## Short answer

Do not approve an unpriced change as an open promise. First classify the change, identify the contract pricing method, calculate known cost plus a bounded allowance for unresolved quantity and time, and write a not-to-exceed amount. Compare that exposure with remaining contingency and ask the lender or program administrator whether funds, draws, appraisal, or disclosures change. Authorize only a written scope, cap, responsible signer, evidence due, and next approval gate.

# How to Approve an Unpriced Custom-Home Change Order Without Losing Budget Control

Do not approve an unpriced change as an open promise. First classify the change, identify the contract pricing method, calculate known cost plus a bounded allowance for unresolved quantity and time, and write a not-to-exceed amount. Compare that exposure with remaining contingency and ask the lender or program administrator whether funds, draws, appraisal, or disclosures change. Authorize only a written scope, cap, responsible signer, evidence due, and next approval gate.

## Decide whether the proposal is safe to authorize before a final price

The safest homeowner decision is to authorize only a defined next action, not an undefined amount of work. A proposal can move forward without a final lump sum when the signed contract permits the pricing basis, the unresolved part is measurable, a not-to-exceed cap is written, the people who must approve it are identified, and the next evidence gate is scheduled. If any of those pieces is missing, pause the work, defer the discretionary part, or reject the change while requesting a better proposal.

This guide sits in Brictale’s [homeowner build blog](/blog), where budget controls connect to design, contractor, construction, and handover decisions.

The word “unpriced” hides several different situations. A builder may know the unit rate but not the quantity. A subcontractor may know the labor rate but not the number of hours. A permit reviewer or designer may still be deciding the extent of the change. A material supplier may have supplied an allowance but not a confirmed product. Or the contractor may be asking for an informal authorization before preparing the formal change order. Each situation has a different control. The homeowner’s goal is not to predict the final invoice perfectly. It is to define the maximum exposure, the records that can change it, and the person who may release the next increment of risk.

For a decision today, use this five-part gate:

| Gate | Question | If the answer is no |
| --- | --- | --- |
| Scope | Can another person tell exactly what is added, deleted, or substituted? | Request a marked-up plan, written scope, or room-by-room description. |
| Pricing | Does the signed contract identify the method, allowable costs, and markup? | Do not assume the builder’s customary markup or a generic change-order rule. |
| Exposure | Can you calculate low, base, and high outcomes and write a cap? | Pause unless an emergency requires a narrowly worded protective directive. |
| Authority | Is the responsible signer identified for homeowner, builder, lender, designer, and authority-having-jurisdiction decisions? | Send the proposal to the missing decision-maker before work starts. |
| Verification | Do you know what invoices, time sheets, measurements, approvals, inspections, or lien records are due? | Convert the missing record into a condition of the next payment or approval. |

The result should fit in one sentence: “Authorize [defined work] under [pricing basis] up to $[cap], with [person] responsible for [record] before [next gate], and with [schedule assumption] stated in writing.” If that sentence cannot be written without words such as “whatever it takes,” “we will see,” or “the usual markup,” the proposal is not controlled yet.

### Original contribution: Pending-change exposure worksheet

The original contribution in this guide is the **Pending-change exposure worksheet**. It is a worksheet, not an official inspection form, legal document, lender form, estimate, or substitute for professional review.

**Method:** Extract the signed contract rule, identify the pricing basis, separate known direct cost from unresolved quantity and schedule effects, apply the contract markup and a stated cap, then compare the modeled exposure with contingency, lender treatment, and the evidence due at the next gate.

**Limitations:** This is an illustrative management tool, not a quote, appraisal, legal opinion, lender approval, permit decision, engineering review, or substitute for the signed contract and project-specific advice from qualified professionals.

The worksheet method is to extract the signed contract rule; identify whether the proposal is lump sum, unit price, time-and-materials, cost-plus, allowance, or a mixture; separate known direct cost from unresolved quantity; add the written markup and schedule exposure without double counting; compare the result with remaining contingency and lender treatment; then record the evidence due and the next decision. The worked numbers later in this article are modeled examples. They are illustrative arithmetic, not quotes, market measurements, or a forecast of a particular project.

Its limitations matter. A worksheet cannot determine whether a proposed structural, electrical, excavation, fire-safety, energy-code, or permit change is technically correct. It cannot decide what the signed contract means under the law of the state where the home is located. It cannot force a lender to fund an overage or make a program rule apply to a loan that is not in that program. It can make the uncertainty visible so the homeowner can ask the right professional the right question before committing money.

The worksheet is useful because it keeps four records together that are often separated: the physical scope, the money exposure, the timing exposure, and the approval evidence. A low estimate without a cap is not approval control. A cap without a scope is not protection. A scope and cap without a record of who approved it can still produce a payment dispute. A signed change without a lender check can create a funding problem even when the builder’s arithmetic is correct.

Your next decision after completing this first gate is one of four choices: proceed with a bounded authorization, proceed only with emergency stabilization, pause while evidence is collected, or reject/defer the discretionary change. Do not use the word “approve” to mean all four.

## Separate the signed contract rule from lender and program examples

Use the signed construction contract as the starting document for the homeowner–builder workflow, subject to applicable law and the project’s actual documents. That is a workflow assumption, not a nationwide legal conclusion about which document controls in every jurisdiction. Questions about mandatory notices, payment rights, lien rights, or enforceability belong with counsel in the state, county, municipality, or tribal jurisdiction where the project is located. HUD guidance, Fannie Mae selling-guide requirements, CFPB disclosure rules, university contract exhibits, and local permit decisions may affect a project, but none automatically rewrites a private contract. Start by identifying the jurisdiction and financing structure, then label every rule as contract, lender, program, federal disclosure, or local authority guidance.

This distinction is the most important protection against false certainty. A document may say that a change needs prior approval in one construction-loan program. That does not establish a universal rule that every U.S. homeowner must use the same form. A university contract exhibit may offer excellent questions about itemization and records. It does not prove that a private residential builder owes those records unless the signed contract includes a similar promise. A federal disclosure rule may govern the lender’s Loan Estimate and Closing Disclosure. It does not set the contractor’s markup or tell a homeowner whether the scope is worth doing.

### Build a jurisdiction and authority map

Write the project location as city, county, state, and, where relevant, tribal jurisdiction. Then write the decision-maker next to each issue. For example:

| Issue | Authority to identify | What the homeowner can ask for |
| --- | --- | --- |
| Change-order notice, pricing, markup, and payment | Signed owner–builder contract and its incorporated exhibits | The exact clause, notice method, markup definition, and payment trigger. |
| Permit, plan revision, inspection, or certificate effect | The city, county, state, or tribal authority having jurisdiction over the site | Whether the change needs a revised permit, inspection, approved drawing, or other local action. |
| Structural, mechanical, electrical, or life-safety design | The licensed designer, engineer, architect, or trade professional responsible for that design, as required in the actual jurisdiction | The revised detail, calculation, equipment requirement, and professional seal or approval if applicable. |
| Construction draws and contingency | The actual lender, construction administrator, or loan program | Whether the change is eligible, which documents are required, and whether funds must be added before work. |
| Loan amount or permanent conversion | The actual lender and the loan’s investor or program rules | Whether a modified amount, re-underwriting, appraisal, or additional borrower funds are required. |
| Site safety | Builder’s site-safety responsibility and applicable federal or state-plan workplace rules | Who controls the site, what protection is required, and whether work must stop. |

For federal workplace safety, OSHA identifies excavation hazards including cave-ins, hazardous atmospheres, water accumulation, utility conflicts, and struck-by hazards, and its guidance calls for safe access and appropriate protective systems based on conditions. [OSHA’s trenching and excavation eTool](https://www.osha.gov/etools/construction/trenching/) supports that hazard and protection summary. OSHA’s federal excavation standard requires the excavation, adjacent areas, and protective systems to be inspected by a competent person daily before work starts, as needed during the shift, and after a rainstorm or other hazard-increasing occurrence when employee exposure can reasonably be anticipated. [29 CFR 1926.651(k)(1)](https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.651) explains that inspection requirement. OSHA also says its approved state plans must be at least as effective as federal standards but may have different or more stringent requirements. [OSHA’s state-plan explanation](https://www.osha.gov/trenching-excavation/construction) supports that jurisdictional qualification. A homeowner can observe, photograph from a safe location, and ask for the builder’s plan. A homeowner should not enter an unprotected excavation, direct a worker’s protective system, or remotely approve a structural or electrical safety decision.

Brictale’s safety boundary is stricter than a remote budget workflow: do not diagnose, test, enter, or authorize pressure-related or contamination-related conditions remotely. That includes suspected pressurized piping, tanks, gas or air systems, uncontrolled water or sewage pressure, contaminated soil, water, or air, and unknown vapors or residues. Route the condition to the responsible qualified professional and site-safety lead; involve the actual city, county, state, tribal, utility, or environmental authority having jurisdiction when its authority applies, and ask the lender only about funding or documentation. The homeowner may record what was observed from a safe location, but must not turn a photograph, call, or text into a remote safety clearance. OSHA specifically includes hazardous atmospheres and contaminated soil among excavation concerns and assigns inspection and corrective control to a competent person. [OSHA’s competent-person guidance](https://www.osha.gov/etools/construction/trenching/competent-person) explains that role; it does not make the homeowner that person.

Electrical and suspected confined-space conditions have the same non-negotiable Brictale boundary: do not remotely diagnose, test, touch, enter, or authorize the work. For electrical work, the on-site qualified electrician or other electrical professional responsible under the project documents must decide the safe action. For suspected confined-space work, the builder’s designated competent person and on-site site-safety authority, with any required qualified professional, must decide whether anyone may approach, enter, test, ventilate, rescue, or continue; OSHA describes the competent person as someone authorized to identify hazards and take prompt corrective measures. [Use OSHA’s competent-person guidance](https://www.osha.gov/etools/construction/trenching/competent-person) to understand that role, not to self-assign it. The homeowner may report observed facts from a safe location and wait for that on-site decision; a photo, call, or text is not a safety clearance.

### Treat the HUD material as a labeled program example

The HUD Section 184 Alaska construction guidance is useful because it shows what a tightly administered construction-loan process can look like. It describes an estimate that includes contingency, a construction escrow, and a change-order request submitted to the lender for prior approval. It says that if an approved change increases cost, the borrower must place additional money into the construction escrow for payment after acceptance. It also describes written borrower approval before each draw. [HUD’s Chapter 9 guidance](https://www.hud.gov/sites/documents/184pg_ch_9_rev_4_8_11.pdf) is a dated program guide for construction loans in remote rural Alaska, not a national rule.

The same guide describes a contingency reserve of at least 10% in that program context, with an exception process and a maximum stated there, and says unforeseen costs above the reserve are paid by the applicant outside the mortgage agreement. [That HUD contingency provision](https://www.hud.gov/sites/documents/184pg_ch_9_rev_4_8_11.pdf) is valuable as a warning about excess exposure, but you must not copy its percentage into a different project. Your lender may use a different percentage, a different account, a different draw procedure, or no construction escrow at all.

The HUD borrower certification form makes the sequencing warning even clearer for that program: the borrower agrees to secure a written and approved change order before changing the approved work write-up and accepts that work started before acceptance may be at the borrower’s own risk and may have to be paid from personal funds. [The HUD borrower certification form](https://www.hud.gov/sites/documents/184pg_ch_4_rev_4_8_11.pdf) is a program-specific example. Use it to ask your lender, “What is the equivalent condition in my loan?” Do not present it to a builder or lender as if it were automatically your contract.

### Ask the lender about documentation, not just permission

If the project uses a single-closing construction-to-permanent loan that follows Fannie Mae requirements, Fannie Mae’s current guide says an increase to the loan amount is permitted only as necessary to cover documented increased construction costs. It also says the lender must underwrite the loan on modified permanent-financing terms; a mismatch with the last DU submission can require resubmission subject to stated tolerances, while specified term changes, document conditions, or an increased loan-to-value ratio can require updated income, employment, and credit documents and borrower requalification. [Fannie Mae’s current selling-guide page](https://guide-selling.fanniemae.com/sel/b5-3.1-02/conversion-construction-permanent-financing-single-closing-transactions) is for eligible transactions delivered under its requirements; it does not promise that your lender will increase the commitment or fund a discretionary upgrade.

Ask the lender four separate questions:

1. Does this change affect the approved construction budget, the schedule of values, the draw request, the commitment, the appraisal, or the permanent-loan conversion?
2. What document must be signed before the builder starts: a lender change form, revised budget, updated plans, borrower funds deposit, or something else?
3. Is the change eligible for loan proceeds, or must it be paid with cash outside the loan?
4. Will an additional inspection, draw fee, modification, re-underwriting, title endorsement, or disclosure be involved?

The CFPB’s Regulation Z Appendix D says that inspection and handling fees, including draw fees for staged disbursement of construction proceeds, are finance-charge loan costs that must be disclosed accurately in the Loan Estimate and Closing Disclosure or applicable addendum timing. [CFPB Appendix D](https://www.consumerfinance.gov/rules-policy/regulations/1026/d/) addresses the lender’s disclosure obligation for covered multiple-advance construction loans. It does not tell you that a particular fee will be charged, nor does it replace your loan documents.

The next decision is whether the proposal is controlled by the contract and funding process you actually have. If you cannot identify both, do not treat a text message, site conversation, or verbal “go ahead” as a complete authorization.

![Decision map showing an unpriced change moving through scope, pricing, exposure, authority, and verification gates before proceed, cap, pause, defer, or reject.](https://brictale.com/images/home/build/budgeting/approve-unpriced-custom-home-change-order/unpriced-change-decision-gate.webp)

## Identify the pricing basis before you calculate the cap

You can only calculate a credible maximum exposure after you know how the change will be priced. Read the signed contract and its incorporated exhibits for the order of precedence, notice deadline, required form, markup, allowance, labor rate, unit-price schedule, cost-plus definition, time extension, and payment condition. Then classify the proposal. If it combines methods, split it into separate lines rather than allowing one blended number to hide the uncertainty.

The Case Western Reserve University facilities exhibit is a useful comparison because it expressly describes lump-sum, unit-price, and cost-plus methods and calls for itemized support. It is an example of contract administration, not a nationwide homeowner rule. [The exhibit’s pricing-method section](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf) says the applicable method depends on the contract provisions and the owner’s rights under that exhibit.

### Lump sum: fixed scope, fixed amount, visible exclusions

A lump-sum change is the easiest to budget when the scope is complete and the amount is truly fixed. Ask for a line-item proposal that states labor, materials, equipment, subcontractors, taxes, permits, design, credits, exclusions, schedule effect, and whether markup is already included. The Case Western Reserve exhibit describes itemized lump-sum proposals with material quantity takeoffs, item prices, labor-hour information, and extensions. It also says supplier quotations should use unit prices for specific items rather than only “lot pricing.” [Those itemization provisions](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf) are a checklist for questions, not a term of your contract unless adopted.

Do not call a proposal lump sum if it contains “allowance,” “estimated quantity,” “to be determined,” “cost to follow,” or “owner to pay actual.” Those words may be reasonable in a temporary authorization, but they describe a different risk. Convert the open item to a unit rate, time-and-materials rule, or bounded allowance.

Before signing a lump sum, compare the new scope with the original scope line by line. Look for deleted work that should create a credit. Ask whether the builder can charge markup on both the addition and the deletion. Check whether the change replaces an allowance or merely adds to it. Confirm who owns the unused material if the selected product changes. Record whether the fixed price includes the complete installation, testing, cleanup, inspection, startup, documentation, and warranty handoff.

### Unit price: known rate, unresolved quantity

A unit-price change is often the best bridge when quantity is the only uncertainty. The formula is:

**Unit-price exposure = unit rate × quantity + applicable fixed costs + markup or included indirect cost + schedule exposure − credits.**

The contract must define the unit. “Per foot” could mean installed linear foot, trench foot, pipe foot, or a measured run that includes fittings. “Each” could include labor, fasteners, testing, trim, and disposal—or only the item. Ask for the measurement rule and who verifies the final quantity. The Case Western Reserve exhibit describes unit-price proposals with itemized quantities tied to specific drawings and applies unit prices to net differences of the same item. [Its unit-price provisions](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf) show why the measurement record matters.

For an unresolved quantity, use three scenarios:

| Scenario | Quantity | Unit rate | Direct quantity cost | What changes the scenario |
| --- | ---: | ---: | ---: | --- |
| Low | 40 LF | $85/LF | $3,400 | Field measurement confirms short run and no added access work. |
| Base | 60 LF | $85/LF | $5,100 | Current drawing and builder takeoff are used. |
| High | 90 LF | $85/LF | $7,650 | Field condition, tie-in, or revised layout increases measured run. |

These figures are illustrative only. They are not a market quote, a local price, or a prediction. If the unit rate itself may change, create a second sensitivity: low, base, and high rates. If the change could add a second unit such as fittings or disposal, list that unit separately. A single blended “per-foot” number can hide a large fixed cost at the beginning and end of the work.

Set the cap above the high modeled exposure only when the added room is intentional and affordable. A cap that equals the base case is not a cap if the known uncertainty points higher. If the high case is unacceptable, the answer is not to label the base case “not to exceed.” Narrow the scope, require a field measurement, defer the work, or reject it.

### Time-and-materials or cost-plus: open books with an outside limit

Time-and-materials pricing can be appropriate for emergency stabilization or genuinely unknown conditions. It is dangerous when the homeowner authorizes “time and materials” without defining rates, allowable costs, markup, records, schedule, and the maximum amount. Define labor categories and rates, whether labor burden is included, equipment rates, supplier discounts, subcontractor markup, taxes, disposal, travel, supervision, small tools, permits, design, and warranty work.

The Case Western Reserve exhibit provides a model for this control: it describes actual direct labor, labor burden, materials, and major equipment plus an approved markup, allows the parties to agree on a maximum price, and calls for daily time sheets distinguishing extra work from base-contract work. [The cost-plus and time-sheet provisions](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf) are not automatically yours, but they show the records a controlled authorization can require.

A useful written directive says that no cost above the cap is payable without a further signed change. It says whether the cap includes tax and schedule cost. It states that unused allowance is credited, not silently consumed. It says the builder must notify the homeowner at a trigger—for example, when 50% of the cap is spent or when the high-case quantity is reached. It states the frequency of reporting and the time allowed for a new decision.

Do not use a cap as permission to spend the whole cap without evidence. Require a running log with date, worker or crew, activity, hours, material receipt, equipment, quantity installed, cumulative cost, remaining cap, and forecast to complete. If the contract does not give inspection or audit rights, ask counsel whether a proposed written change can add a practical record requirement.

### Allowance, estimate, and directive: three different temporary tools

An allowance is a temporary budget line, not automatically a fixed price. It should state what it includes, what it excludes, the basis for adjustment, and how the final credit or charge is calculated. An estimate is a forecast that can move. A directive is an instruction to perform defined work before the final change amount is negotiated. Do not let the contractor’s label decide the financial effect.

For a temporary directive, write the reason for acting before price is final. There are two different reasons: preventing imminent damage and preserving a convenience or preference. A leaking temporary roof opening may require immediate protection; a larger window, upgraded tile, or extra outlet usually can wait for pricing and approval. Emergency work should be limited to stopping the hazard or damage, with the discretionary enhancement split into a later decision.

The Case Western Reserve exhibit describes a situation in which changed work may proceed on a cost-plus basis with an agreed not-to-exceed price and written confirmation while the parties negotiate the final change. That is a model of a bounded directive, not a right that every homeowner has. [Its notice-to-proceed language](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf) reinforces the need to confirm the temporary instruction in writing.

Your next decision is the pricing method that can be verified. If no method can be stated, the proper output is a request for information or a pause—not an open-ended authorization.

## Calculate maximum financial exposure with the worksheet

The maximum exposure is the highest amount you are willing and able to commit under the stated assumptions, not the contractor’s first estimate. Build it from separate lines so that the unresolved quantity, markup, schedule, and lender effects remain visible. Use the high case for the authorization cap when the high case is credible and affordable; otherwise change the scope or defer the decision.

### Worksheet: identify the change before entering money

Copy this table into your project decision log. Empty cells are not neutral; they are evidence due before the next gate.

| Field | Homeowner entry | Why it matters |
| --- | --- | --- |
| Change ID and date |  | Prevents a verbal request from becoming an untraceable commitment. |
| Original scope and document reference |  | Establishes what was already included and what may be credited. |
| Proposed change |  | Defines the addition, deletion, substitution, or correction. |
| Reason |  | Separates owner preference, design coordination, concealed condition, code/permit issue, and emergency protection. |
| Pricing basis | Lump sum / unit price / T&M / cost-plus / allowance / mixed | Determines which inputs and records are required. |
| Responsible estimator |  | Names builder, trade, designer, or other person responsible for the number. |
| Contract clause and notice requirement |  | Prevents a project custom from replacing the signed agreement. |
| Known direct labor, material, equipment, and subcontractor cost | $ | Creates an auditable starting point. |
| Unresolved quantity and unit |  | Makes the uncertainty measurable. |
| Low / base / high quantity |  | Shows sensitivity instead of hiding a single guess. |
| Markup and what it includes | % or $ | Avoids double counting overhead, profit, supervision, and warranty. |
| Credits or deleted work | $ | Prevents the new cost from ignoring scope removed. |
| Permits, design, testing, inspection, tax, disposal, and fees | $ | Captures project costs outside the visible material price. |
| Schedule days low / base / high | days | Connects money to time and handoffs. |
| Carrying cost per day | $/day | Models temporary housing, interest, storage, insurance, and other documented effects. |
| Contingency before change | $ | Measures remaining resilience. |
| Other committed changes not yet paid | $ | Avoids treating unused contingency as available twice. |
| Lender or program treatment |  | Records eligibility, deposit, draw, appraisal, and disclosure questions. |
| Not-to-exceed cap | $ | Defines the maximum authorized exposure. |
| Responsible signer |  | Identifies who may authorize the scope and money. |
| Evidence due before start, draw, and closeout |  | Turns verification into a condition, not a hope. |
| Result | Proceed / capped proceed / pause / defer / reject | Makes the next decision visible. |

### Formula: direct cost, uncertainty, time, and credits

For a unit-price change, calculate each scenario independently:

**Scenario exposure = known direct cost + (quantity × unit rate) + permits/design/testing/fees + schedule days × carrying cost per day + markup − credits.**

If markup applies only to certain direct costs, apply it only to those lines. If the unit rate already includes markup or indirect cost, do not add it again. If the contract calls for separate tax, disposal, or subcontractor markup, show those lines explicitly. If schedule days overlap with an existing delay, do not charge the same day twice; record the assumption and ask the builder to identify the critical-path effect.

For time-and-materials work, use:

**Scenario exposure = labor hours × contract labor rate + material receipts + equipment hours × contract equipment rate + approved subcontractors + stated fees + applicable markup + schedule exposure − credits.**

The cap should cover the high case only if it is a real authorization you can tolerate. It should include a trigger for re-approval before the cap is reached. If the cap is $12,500, the builder should not be told “you have $12,500 to spend”; the instruction should say what work can be done, which records are required, and when the builder must stop and request a new decision.

### Worked example: modeled unit-price sensitivity

Consider an illustrative custom-home change involving additional site drainage work. This example does not establish a price for excavation, drainage, pipe, labor, or any location. It is a calculation demonstration only. Because excavation can expose workers to cave-ins, utilities, water, and hazardous atmospheres, a qualified builder and the site’s responsible safety professional must control the work. The homeowner should remain outside the work area and should not treat this example as field direction.

Assume the following modeled inputs:

- Known direct cost for a revised connection and fixed mobilization: **$2,400**.
- Unresolved quantity: **40, 60, or 90 LF**.
- Illustrative unit rate: **$85/LF**.
- Illustrative markup assumption: **10% on the known direct and unit-price work**. This is not a claimed industry standard; replace it with the signed contract rule.
- Permit/design/inspection allowance: **$650**, to be verified with the local authority having jurisdiction and the responsible designer.
- Carrying-cost sensitivity: **$120/day**, a homeowner-entered assumption, not a quote.
- Schedule sensitivity: **3, 5, or 8 days**.
- Credits: **$0** in this example because no original work is deleted.

| Scenario | Quantity cost | Direct work before markup | 10% modeled markup | Schedule exposure | Fixed professional/fee line | Modeled exposure |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| Low: 40 LF, 3 days | $3,400 | $5,800 | $580 | $360 | $650 | **$7,390** |
| Base: 60 LF, 5 days | $5,100 | $7,500 | $750 | $600 | $650 | **$9,500** |
| High: 90 LF, 8 days | $7,650 | $10,050 | $1,005 | $960 | $650 | **$12,665** |

The arithmetic is: direct work before markup equals $2,400 plus quantity cost. Markup equals 10% of that direct-work subtotal. Schedule exposure equals days multiplied by $120. Modeled exposure adds the fixed $650 line. If the homeowner can tolerate no more than $10,000, the proposal cannot be approved with the high-case quantity and schedule still open. The choices are to measure the work before authorization, reduce the scope, set a cap below the high case and stop at the trigger, or defer/reject the discretionary portion.

Sensitivity is more useful than false precision. If the carrying assumption rises from $120/day to $250/day, the base schedule line becomes $1,250 rather than $600, increasing the base modeled exposure to $10,150. If the unit rate rises from $85/LF to $105/LF while the base quantity remains 60 LF, the quantity line becomes $6,300 and the base exposure becomes $10,820. If both occur, the homeowner should not use the original cap. Write the changed input, date, source, and approval before accepting the revised forecast.

![Comparison graphic showing low, base, and high modeled change-order exposure with quantity, markup, schedule, and cap sensitivity.](https://brictale.com/images/home/build/budgeting/approve-unpriced-custom-home-change-order/change-exposure-sensitivity-comparison.webp)

### Worked example: modeled time-and-materials cap

Now assume an illustrative repair to resolve an unforeseen condition. Again, no figure below is a quote. The contract may use completely different rates or prohibit this method.

- Labor: **48 hours × $72/hour = $3,456**.
- Materials: **$2,150**, supported by itemized receipts.
- Major equipment: **14 hours × $95/hour = $1,330**.
- Approved subcontractor: **$1,800**.
- Direct-cost subtotal: **$8,736**.
- Illustrative markup assumption: **12% = $1,048.32**.
- Permit, disposal, or testing allowance: **$450**.
- Schedule exposure: **6 days × $120/day = $720**.
- Modeled base exposure: **$10,954.32**.

An illustrative $12,500 cap leaves $1,545.68 between the modeled base and the cap. That difference is not automatically a contingency reserve. It is the remaining room for the defined work, and it disappears if the labor hours, materials, equipment, subcontractor scope, or schedule increases. The written authorization should require notification when the direct-cost subtotal reaches $7,000, when 36 labor hours are used, or when the work will exceed six days—whichever occurs first. The builder then supplies a forecast and the homeowner decides whether to stop, amend the cap, reduce scope, or reject the remaining work.

If the builder says the cap is impossible to manage because the condition is unknown, narrow the directive to investigation or stabilization. For example, authorize a limited exploratory step with its own cap and a deliverable: measured condition, photographs taken by the builder for the project record, affected drawings, a proposed permanent remedy, and updated low/base/high costs. Do not authorize permanent work merely because exploration was necessary.

### Compare exposure with contingency without borrowing certainty

Your remaining contingency is not the same as unspent budget. Start with the original contingency. Subtract approved changes, committed but unpaid changes, lender-required reserves, and any known owner selections that still lack a final price. Then compare the high modeled exposure, not only the base, with what remains. If the high case consumes most of the reserve, a small additional change can leave the project fragile.

Record three balances:

1. **Contract balance:** original contract amount plus signed changes and credits.
2. **Cash exposure:** money the homeowner may need to pay outside the loan, including ineligible changes, deposits, fees, and overruns.
3. **Funding balance:** what the lender or program has confirmed is eligible and available in the relevant account or draw structure.

These balances can diverge. A change may be contractually allowed but not loan-eligible. A lender may accept a revised budget but require additional borrower funds. A builder may have a signed change but still need a permit or inspection before proceeding. A contingency line may exist in the budget but not be withdrawable at the homeowner’s discretion. The HUD Section 184 materials illustrate this separation by linking contingency use and increased-cost changes to escrow and lender approval in that program context. [HUD’s construction-loan change-order guidance](https://www.hud.gov/sites/documents/184pg_ch_9_rev_4_8_11.pdf) should be read as an example of a program gate, not a universal financing rule.

Your next decision is the maximum amount you will authorize and the maximum amount you will fund. They should be the same only if the contract, lender, and cash plan all support that conclusion.

## Run the approval sequence with named handoffs

An unpriced change should move through a sequence: capture, classify, price, technical review, lender check, written authorization, controlled execution, measurement, payment verification, and closeout. The homeowner coordinates the decision but should not silently take over the builder’s estimating, engineering, site-safety, or lender responsibilities.

The handoff has five distinct lanes: the homeowner captures the request, checks the exposure, obtains the required responses, and signs the financial decision; the builder or trade defines the field scope, supplies the pricing basis, controls execution, and reports measured cost and time; the designer or engineer answers the technical-design question; the actual city, county, state, tribal, utility, or other authority having jurisdiction answers the permit and inspection question; and the lender or program administrator answers funding, draw, disclosure, and re-underwriting questions. The sequence is capture, classify, assemble inputs, price, technical and permit review, funding check, written authorization, controlled execution, measurement, payment verification, and closeout. Each lane answers only its own question, so one party’s signature or site visit does not stand in for another lane’s approval.

![Swimlane sequence showing change-order handoffs among homeowner, builder, designer or engineer, local authority, and lender from request through closeout.](https://brictale.com/images/home/build/budgeting/approve-unpriced-custom-home-change-order/change-order-approval-handoff-sequence.webp)

### Step 1: capture the request and freeze informal authorization

Create a change ID. Record who raised the issue, when, where it appears in the plans or site, what will happen if nothing is done, and whether the request is an emergency. Send a short written response: “Received for review; this is not authorization to proceed except for separately identified emergency protection.” This protects the decision boundary without asserting a legal result.

Ask the builder to identify whether the change is an owner request, a design revision, a correction to an omission, a concealed condition, a permit or inspection requirement, or a safety measure. Responsibility and cost treatment may depend on that classification under the contract. Do not decide fault from photographs or a remote conversation. Preserve the original drawings and the affected revision so the comparison can be made later.

### Step 2: assemble the input packet

The homeowner should provide the signed contract, incorporated plans and specifications, current schedule of values, approved allowances, prior changes, current contingency, draw status, and the reason for considering the change. The builder should provide a written scope, pricing basis, assumptions, exclusions, quantities, schedule effect, and records required. The designer or engineer should provide the revised detail when the change affects design responsibility. The lender should state funding and documentation conditions. The local authority having jurisdiction should decide permit and inspection questions for the actual site.

Do not ask one person to answer every question. A builder may know sequencing and labor; a structural engineer may know whether a detail is adequate; a lender may know draw eligibility; a city or county reviewer may know whether a permit revision is required. The homeowner’s job is to make the handoff explicit and wait for the responsible answer before approving the dependent work.

### Step 3: request the proposal in the right form

For lump sum, request a line-item amount with additions, deductions, tax, markup, schedule days, exclusions, and completion condition. For unit price, request unit definitions, measured quantity, low/base/high quantities, measurement method, rate validity, and who signs the final measurement. For time-and-materials, request labor categories and rates, equipment rates, allowable materials, subcontractor treatment, markup, daily records, update frequency, and cap. For an allowance, request the exact item, selection deadline, included installation, credit/charge formula, and price source.

The Case Western Reserve exhibit’s itemized approach is useful because it places materials, quantities, labor hours, and extensions next to one another. It also describes a right to verify pricing data in the underlying records for the period stated in that exhibit. [The exhibit’s verification provisions](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf) should prompt you to check your actual contract for audit, invoice, and record-retention rights rather than assuming them.

### Step 4: obtain technical and local review

If the change touches structure, load paths, excavation, retaining conditions, electrical service, gas, fire separation, egress, foundations, drainage, energy compliance, or equipment sizing, route it to the qualified professional responsible for that subject. Ask for the revised drawing, specification, calculation, or written instruction that makes the scope buildable. The homeowner should not approve technical work by comparing two product photos or by relying on an internet diagram.

Ask the authority having jurisdiction for the actual local effect: permit revision, inspection sequence, fee, reinspection, approved drawing, or certificate consequence. Name the city, county, state, or tribal authority in the project record. Do not write “code requires” unless the responsible jurisdiction or professional has identified the actual provision and it applies to this site.

For work near utilities or below grade, keep the homeowner out of excavation and utility-clearance decisions. OSHA’s federal excavation standard requires a competent person to inspect before work, daily, as needed during the shift, and after a rainstorm or other hazard-increasing event when employee exposure can reasonably be anticipated. [29 CFR 1926.651(k)(1)](https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.651) is the exact inspection provision, while [OSHA’s competent-person guidance](https://www.osha.gov/etools/construction/trenching/competent-person) describes the authority to identify hazards and take prompt corrective measures. These are safety boundaries, not homeowner excavation procedures. Do not diagnose, test, enter, or authorize a pressure-related or contamination-related condition from a remote conversation; route it to the responsible qualified professional, site-safety lead, or actual authority having jurisdiction as applicable.

### Step 5: obtain the lender or program response

Send the lender a concise packet: original scope, proposed change, low/base/high exposure, cap, funding source, schedule effect, revised plans if any, permit status, and requested draw timing. Ask for a written response that distinguishes “eligible for loan proceeds,” “requires borrower deposit,” “requires revised documents,” “requires inspection,” and “not eligible.” Keep the response with the change record.

If the lender says the change affects the commitment or permanent conversion, ask what happens to the loan amount, appraisal, title, underwriting, cash-to-close, or permanent payment. Fannie Mae’s guide states that documented increased construction costs are relevant to loan-amount increases in its eligible transaction context; the practical lesson is to document the cost before expecting financing treatment. [Fannie Mae’s construction-to-permanent guidance](https://guide-selling.fanniemae.com/sel/b5-3.1-02/conversion-construction-permanent-financing-single-closing-transactions) is not a guarantee for your loan.

If the lender charges staged-draw inspection or handling fees, ask where they appear and when they are due. CFPB’s Regulation Z guidance treats those fees as disclosed loan costs for covered multiple-advance construction loans. [CFPB Appendix D](https://www.consumerfinance.gov/rules-policy/regulations/1026/d/) supports asking for the disclosure treatment; it does not establish the fee amount.

### Step 6: sign the narrowest written authorization

The authorization should identify the change ID, revised documents, pricing basis, cap, included and excluded work, schedule assumption, permits and inspections, funding source, payment condition, reporting frequency, stop triggers, responsible signers, and next gate. State that work outside the scope or above the cap requires a new written authorization, subject to the contract and any emergency terms.

Do not rely on a signature block alone. The body of the document should say whether it changes the contract price, contract time, both, or neither until later measurement. It should say whether a deduction is included. It should say whether the builder may order long-lead materials and under what cap. It should state what happens to unused allowance or unspent cap.

### Step 7: close the change with measurement and records

At the next draw or invoice, compare installed work with the approved scope. For unit price, use a dated quantity measurement signed by the designated parties. For time-and-materials, compare daily time sheets, receipts, equipment logs, and subcontractor invoices with the approved work. For lump sum, confirm the stated completion condition and any inspection or testing requirement. For every method, record credits, unused allowances, and schedule outcome.

Where the loan program requires it, the lender may need an inspection or specific draw documents before funds are released. The HUD Section 184 Alaska guide describes inspections, draw requests, and written borrower approval as part of its program-specific process. [HUD’s draw and change-order section](https://www.hud.gov/sites/documents/184pg_ch_9_rev_4_8_11.pdf) demonstrates why a homeowner should not treat construction progress and lender release as the same decision.

The next decision is whether the evidence supports payment and closeout. If the quantity, receipt, permit, inspection, or lien record is missing, pause that payment or escalate through the contract process rather than silently rolling the amount into the next draw.

## Verify the change before work, payment, and closeout

Verification should be staged: verify authorization before work, verify actual quantity and condition during work, verify completion before payment, and verify the final record before closing the change. A homeowner may collect documents and ask questions, but technical inspections, engineering opinions, worker safety, and local approval belong to the responsible professionals and authorities.

### Before work starts

Use this pre-start checklist:

- Original scope and affected drawing revision are attached.
- The reason for the change and the consequence of doing nothing are written.
- The pricing method and contract clause are identified.
- Low, base, and high quantities or hours are shown.
- Markup is stated and its included costs are listed.
- Credits and deleted work are shown.
- Permit, design, inspection, testing, tax, disposal, and schedule lines are addressed.
- The not-to-exceed cap is written in dollars and applies to a defined scope.
- A stop trigger and a forecast-update trigger are written.
- The responsible homeowner and builder signers are named.
- The lender or program response is attached if financing could be affected.
- The local authority having jurisdiction or responsible designer has answered permit and technical questions.
- The builder confirms site-safety responsibility and the homeowner will not enter hazardous work areas.

For a program-specific example, HUD’s borrower certification says the borrower will secure written and approved change orders before changing the approved work write-up and accepts risk for work started before acceptance. [Read that form in its own program scope](https://www.hud.gov/sites/documents/184pg_ch_4_rev_4_8_11.pdf); do not generalize it to every loan.

### During work

Set a reporting interval suited to the uncertainty. A small, fixed lump sum may need a completion check. A large time-and-materials excavation may need daily records. The report should show cumulative direct cost, markup, schedule days, quantity installed, remaining cap, and forecast to complete. Ask for an immediate notice if a condition changes the high case, affects the critical path, requires a permit revision, or changes the design.

For unit price, require a measurement record that can be reconciled to a drawing, field dimension, delivery ticket, or other project record. For material, require invoices or purchase orders that identify the item, quantity, and project allocation. For labor, require category, hours, and task. For equipment, require the equipment identity, hours, and rate basis. For subcontractor work, require the subcontractor scope and the builder’s markup treatment. These records are not proof that the price is fair by themselves; they show what was purchased and performed.

The Case Western Reserve exhibit makes this relationship explicit in its model cost-plus clauses: daily time sheets distinguish extra work from base work, and the owner’s representative can examine records to verify pricing data under the exhibit. [Use the exhibit as a record checklist](https://case.edu/facilities/sites/default/files/2024-10/410%20Pricing%20of%20Construction%20Contract%20Change%20Orders.pdf), while checking whether the signed home contract grants comparable rights.

### At the draw or invoice

Do not approve a draw merely because the contractor requests it. Match the request to the payment condition in the contract and loan documents. Check work completed, accepted materials, inspections, approved change orders, lien waivers or releases where required, and the remaining cap. If the lender’s inspector or the authority having jurisdiction has a separate role, do not substitute a homeowner photograph for that professional record.

The CFPB disclosure rules and HUD program guidance address different things. CFPB Appendix D addresses lender disclosure of construction-loan inspection and handling fees. HUD Section 184 Alaska guidance addresses a particular construction-loan administration process that includes inspection and draw records. [CFPB’s disclosure guidance](https://www.consumerfinance.gov/rules-policy/regulations/1026/d/) does not approve the work. [HUD’s program guide](https://www.hud.gov/sites/documents/184pg_ch_9_rev_4_8_11.pdf) does not govern a conventional loan unless the project is actually in that program context.

### At completion and closeout

Close the change with a final line-item reconciliation. Record the approved cap, actual direct cost, markup, credits, schedule change, lender treatment, and amount paid. Attach final drawings, permit or inspection records, equipment serials if relevant, warranties, maintenance instructions, and releases required by the actual contract. Mark the change “closed” only when the physical work and financial record both match the authorization.

If the final amount is below the cap, record the unused balance. It may return to contingency, become a credit, or remain subject to the contract or lender process. Do not assume it is automatically available for a new upgrade. If the final amount exceeds the cap, do not backdate approval. Record the reason, stop further non-emergency work, and ask for a new decision under the contract. A later signature may resolve the project’s next step, but it does not make the earlier open authorization precise.

Your next decision is whether the completed change improves the home enough to justify the cash, schedule, maintenance, and financing effects. Closeout is not a paperwork afterthought; it is the evidence needed for the next change and for later ownership.

## Choose proceed, cap, defer, or reject when the price is still open

Proceed only when the scope is defined, the pricing basis is contract-compatible, the high modeled exposure fits the financial plan, the lender and local handoffs are clear, and the records due are written. Cap when work must continue but quantity or hours remain uncertain and a real stop trigger can protect the homeowner. Defer when the work is desirable but not necessary to protect the project, comply with an identified requirement, or preserve a time-sensitive opportunity. Reject when the scope, exposure, authority, or evidence cannot be made acceptable.

### Proceed with a bounded authorization

Choose proceed when all of these are true:

- The change solves a documented problem or fulfills a deliberate owner decision.
- The original scope and the new scope can be compared.
- The contractor has identified the pricing basis and contract clause.
- The high case is acceptable or has been reduced through measurement and scope control.
- The written cap covers the defined work and schedule assumption.
- The lender has confirmed treatment when funding may be affected.
- Required professional and local reviews are complete or the authorization is expressly limited to the pending step.
- The next payment and closeout evidence are known.

The approval sentence should state the cap, but it should also state the stop rule. Example: “Proceed with the revised utility chase shown on drawing A-203 revision 4 using the contract unit rates; measured quantity will be verified at installation; total change exposure may not exceed $9,800 including the stated markup, permit, inspection, and five schedule days; builder must notify owner at $7,000 direct cost or if the quantity exceeds 60 LF; no work outside the described chase is authorized.” This is a modeled drafting example, not a legal form.

### Proceed with a capped investigation or emergency stabilization

Choose capped proceed when the project cannot safely wait, but the permanent solution is unknown. Split the work into two authorizations. The first authorizes only investigation, temporary protection, or stabilization with its own cap and records. The second will authorize the permanent change after the condition is measured and priced. For example, a temporary weather barrier, controlled water removal, or a limited exploratory opening may be different from installing a redesigned permanent system.

The separation prevents an emergency from becoming a blank check. State who decides that the emergency is over. Require a report by a fixed time or event. State whether the contractor can continue after stabilization without a new signed decision. Where the condition includes excavation, electrical exposure, structural instability, gas, fire, or confined space risk, the qualified professional and site-safety authority decide what work is safe.

### Pause or defer the discretionary scope

Choose pause when the work is optional and the price, quantity, financing treatment, or design is unresolved. A pause is not indecision; it is a deliberate choice to preserve budget and evidence. Ask the builder to carry a temporary line in the change log, identify the last date at which the decision affects schedule or procurement, and state whether deferral creates a known later cost.

Choose defer when a decision can be made after a higher-priority dependency. A cabinet upgrade may wait for final layout coordination. A finish selection may wait for a sample and allowance reconciliation. A larger window may wait for structural and energy review. A site change may wait for a survey or utility location. Put a date on the deferral and define the next gate; otherwise deferred choices become late decisions with less leverage.

### Reject the proposal or the method

Reject the proposal when the owner does not want the result, the cap exceeds the available exposure, the work conflicts with the design brief, the lender will not fund it and cash is unavailable, the schedule effect is unacceptable, or the builder cannot supply the records required by the contract. Reject the method when the proposed “allowance” has no adjustment formula, the proposed T&M has no rates or cap, or the proposed lump sum is full of unresolved exclusions.

A rejection should be precise: “Do not perform the proposed upgrade; preserve the original scope and notify us if procurement, permit, or schedule consequences require a separate decision.” Do not reject a safety measure that is necessary to protect workers or the home. Instead, ask the responsible builder or professional to isolate the protective work from the disputed discretionary scope and price it separately.

### Failure matrix: common ways the control breaks

| Failure case | What the homeowner may observe | What it does not prove | Safer next action |
| --- | --- | --- | --- |
| “We need a yes today; price to follow.” | Work is described as urgent, but no cap is offered. | It does not prove that all work is urgent or that the final cost is small. | Authorize only emergency stabilization with a cap and require a permanent proposal. |
| “It is just an allowance.” | A budget line exists with no final selection or installation scope. | It does not prove the allowance covers tax, labor, trim, or installation. | Request included/excluded items, selection deadline, and credit/charge formula. |
| “The unit price is fixed.” | Rate is stated but quantity is not measured. | It does not prove the rate covers every fitting, mobilization, disposal, or markup. | Define the unit, measurement method, fixed costs, and high quantity. |
| “T&M is transparent.” | Hours and receipts will be sent later. | It does not prove the rates, markup, task allocation, or cap are controlled. | Set rates, records, reporting trigger, and not-to-exceed amount before start. |
| “The lender will include it.” | The original loan includes a contingency or construction budget. | It does not prove this change is eligible or that the commitment increases. | Obtain written lender treatment and identify any borrower deposit or disclosure. |
| “The inspector saw it.” | Someone visited the site or viewed a photograph. | It does not prove design approval, permit approval, quantity acceptance, or lender release. | Identify the inspector’s authority and the exact report or approval required. |
| “We can fix the paperwork later.” | Work has started under a text, call, or field conversation. | It does not prove the change is authorized or fundable. | Stop non-emergency work and document the scope, cost, time, and responsibility before continuing. |
| “There is plenty of contingency.” | The budget shows an unused reserve. | It does not prove other pending changes, lender holds, or cash needs are covered. | Reconcile original, committed, approved, and lender-available balances. |

If a builder refuses a reasonable request for the contract basis, quantity, cap, or records, do not fill the gap with your own estimate and call it approval. Bring the contract, proposal, drawings, budget, and communication history to a construction attorney, architect, engineer, owner’s representative, or other qualified professional appropriate to the issue. That is especially important when the dispute involves payment rights, delay, lien exposure, or alleged defective work.

## Make the next decision visible in your project record

The next decision is not “Did we sign the change?” It is “What must happen before the next dollar, day, or irreversible piece of work is committed?” Write that gate at the bottom of the worksheet. A useful record includes the decision, date, signer, scope reference, cap, current forecast, evidence still due, and the person responsible for delivering it.

Use this compact decision log:

| Decision record | Entry |
| --- | --- |
| Current result | Proceed / capped proceed / pause / defer / reject |
| Authorized action |  |
| Maximum exposure |  |
| Maximum schedule effect |  |
| Funding source | Contract budget / contingency / lender draw / homeowner cash / unresolved |
| Evidence due next |  |
| Responsible person |  |
| Date or trigger for next gate |  |
| Condition that stops work or payment |  |
| Final closeout record |  |

For a homeowner with a construction loan, keep the contract balance, cash exposure, and funding balance on the same page. For a homeowner paying directly, keep the same structure but replace lender fields with payment milestones, receipt requirements, and any local permit or inspection handoffs. For a project in the United States, name the actual city, county, state, or tribal authority whenever a permit or local rule is involved. For a project using the HUD Section 184 Alaska process, identify the lender and program administrator and follow the actual program documents rather than this guide’s general worksheet.

The worksheet can also improve the builder conversation. It does not accuse the builder of overcharging when it asks for a measurement basis. It does not reject a legitimate unknown when it provides a fair cap and a record path. It separates the homeowner’s decision to buy an outcome from the builder’s responsibility to price and perform the work. It gives the lender a documentable funding question instead of a vague request to “cover the overage.” It gives the designer or authority having jurisdiction a defined technical question instead of a request for remote approval.

### Compact originality brief

Current answers commonly explain that change orders alter cost or schedule, describe contingency in general terms, or list pricing methods from a contractor or lender perspective. The missing decision is how a homeowner should authorize an incomplete proposal without converting uncertainty into unlimited exposure.

This guide’s original contribution is the pending-change exposure worksheet plus two sensitivity models. It can be checked by reproducing the formulas, replacing the illustrative inputs with the signed contract’s rates and the project’s measured quantities, comparing the high case with the reconciled contingency and cash balance, and verifying each lender, permit, design, inspection, and payment handoff against its actual document. Its limits are explicit: it is not a quote, code interpretation, professional inspection, lender approval, legal opinion, or empirical study.

The final test is simple: could a person who was not in the site conversation read the change record and know what is being authorized, how much exposure is allowed, who must act next, what evidence is due, and when the homeowner gets to decide again? If yes, the unpriced change has become a controlled decision. If not, preserve the original scope and ask for the missing boundary before authorizing more work.
