Custom Home Change Orders: Costs, Timing, and How to Avoid Surprises

A custom home change order is a written agreement that modifies the approved plans, specifications, price, or construction timeline after the original scope has been established. Change orders are common in custom construction, but homeowners should understand the full cost, schedule impact, affected work, and payment requirements before authorizing one.

In Episode 12 of the Building With Breven podcast, Bryan and Steven Byrnes explain why changes arise, how a builder evaluates them, and why a request that sounds simple may involve several trades, additional materials, administrative work, or completed work that must be removed and rebuilt. The goal is not to eliminate every change. It is to make each decision deliberately and document it clearly.

This guide turns the episode into a practical resource for homeowners planning or building a custom home in Central Texas. It focuses on owner-requested changes, which are the primary subject of the episode. Your construction agreement may also address other changes, such as unforeseen conditions or required revisions, so the signed contract remains the controlling document.

Quick Answer: What Should Homeowners Know About Change Orders?

Before approving a custom home change order, confirm all of the following in writing:

The exact work being added, removed, relocated, or replaced

The plan pages, specifications, selections, or details affected by the change

The total price increase or credit, including builder fees or markups stated by the agreement

Whether design, engineering, permits, inspections, or lender approval are required

The effect on the construction schedule and the revised completion date, if any

When payment is due and whether the change can be funded through the construction loan

Who must sign the change order before materials are ordered or work begins

How the approved change will be added to the plans, project log, and homeowner records

Do not rely on a verbal request, text message, or site conversation alone. A documented change protects both the homeowner and the builder by creating one agreed record of the revised scope, price, and timing.

What Is a Change Order in Custom Home Construction?

A change order formally amends the construction agreement after the parties have approved the original scope. The American Institute of Architects describes its G701 change order as a document used to implement changes agreed to by the owner, contractor, and architect, including changes to the contract sum and contract time. A residential builder may use a different form, but the underlying purpose is similar: define the change and record the parties' approval.

Episode 12 starts with the signed plan set. Breven Homes asks homeowners to sign the final pages so the team has a clear construction baseline. If the homeowner later asks to add an electric-vehicle circuit, enclose a dining room, move a wall, change a finish, or revise another part of the approved work, the builder must compare that request with the baseline and determine what else it affects.

Change order versus a minor field adjustment

Not every small adjustment is handled the same way. The episode gives the example of shifting a switch a short distance before insulation and drywall. Breven Homes may treat a limited adjustment like that differently from a request requiring new materials, extra labor, return visits, redesign, or rework. Another builder may document every deviation as a formal change order. Ask for the builder's written policy rather than assuming a small change will be free or informal.

Why Do Change Orders Happen During a Custom Home Build?

The home feels different when it becomes three-dimensional

A floor plan cannot reproduce the experience of walking through framed rooms. Once the walls are visible, a homeowner may notice that a doorway, outlet, furniture layout, sightline, or room relationship would work better another way. That discovery does not necessarily mean the original plan was wrong. It means the physical space revealed information that was difficult to judge on paper.

A need or preference was not included in the final plans

The episode uses an electric-vehicle charger as an example. If the circuit and outlet were not included in the approved electrical plan, adding them changes the original scope. Similar requests may involve extra storage, a different appliance, specialty lighting, low-voltage wiring, an added door, or a finish upgrade.

The homeowner changes a selection or room function

A homeowner may decide to convert an open dining area into an enclosed study, substitute carpet for hardwood, or change a fixture after the related trade has already planned or completed its work. The builder must identify both the added work and any credit for work no longer required. Credits do not always equal the retail price of the deleted item because purchasing, labor, restocking, scheduling, or completed work may also be involved.

The request arrives after construction has advanced

Timing can turn a manageable revision into a difficult one. Moving a wall while framing is underway is different from moving it after electrical, plumbing, HVAC, insulation, drywall, trim, and flooring have been installed. The later request may require demolition, engineering, trade return visits, inspections, replacement materials, and repairs to finished surfaces.

What Should a Written Change Order Include?

The National Association of Home Builders' contract resources include separate change-order forms for fixed-fee and cost-plus projects. Both identify changes to the specifications or scope and provide for price or cost and completion-time changes to be noted and agreed to by the customer. Your builder's form may look different, but a useful change order should make the decision understandable without relying on memory.

A clear description of the requested change and the reason for it

References to the affected plan sheets, specifications, selections, or room locations

Drawings, marked-up plans, product information, or photographs when words are not enough

The work and trades included, plus any work specifically excluded

The added cost, deleted cost, net credit, allowances, fees, and applicable builder markup

The required deposit or payment timing and whether work is contingent on lender approval

The number of calendar or working days added to the schedule, or a statement that no extension is expected

The revised completion date when the effect can be established

The date through which pricing and material availability remain valid

Approval signatures from the parties required by the contract

The Federal Trade Commission's contractor guidance also recommends a written contract that identifies the work, materials, completion timing, price, and promises made during conversations. Although that guidance is broader than new custom-home construction, the same documentation principle is useful: important commitments should not remain only in calls, texts, or informal conversations.

Why Can a Small Change Cost More Than Expected?

Homeowners naturally compare the quoted change-order price with the visible product. A receptacle, door, fixture, or section of lumber may look inexpensive online, but the product price is only one part of the change. The builder must price the work required to integrate it into an active construction project.

Several trades may be affected

Enclosing a dining room can affect framing, electrical routing, HVAC supply or return locations, drywall, trim, paint, flooring, doors, hardware, plans, and inspections. A structural change may also require the architect or engineer to revise details before a trade can proceed.

Completed work may need to be removed or repeated

If the request arrives after work has been installed, the change-order price may include safe removal, disposal, protection of adjacent finishes, replacement work, repairs, and new inspections. The project is paying not only for the new result but also for the process of undoing and rebuilding part of the original scope.

Trades may charge for additional mobilization

A subcontractor who completed the scheduled visit may need to return outside the original sequence. That return can require travel, setup, supervision, coordination, and a new minimum service charge even when the visible task is small.

The builder must coordinate and document the change

A responsible builder identifies affected trades, obtains pricing, checks constructability, updates the schedule, prepares the change-order document, communicates the approved revision, updates project records, and verifies that the field work matches the agreement. Episode 12 also notes that some contracts allow the builder to charge for the time spent pricing a requested change even if the homeowner ultimately declines it. Confirm that policy before construction begins.

How Does Timing Affect a Change Order?

Changes made before the affected work begins

An early change may still require design work, updated pricing, or different materials, but it can avoid demolition and duplicated labor. If a dining room is enclosed before framing starts, the team can order and schedule the revised scope in the proper sequence. Early does not always mean inexpensive, but it usually gives the team more options.

Changes made while the affected phase is active

A request made during framing, rough-in, or another active phase may be feasible if the builder can pause the affected work without disrupting the rest of the project. Fast homeowner decisions matter because trades may be scheduled closely together and materials may have ordering deadlines.

Changes made after the work is concealed or finished

After insulation and drywall, changing framing or mechanical systems becomes more disruptive. Finished flooring, cabinetry, tile, paint, or exterior materials can increase the amount of protection and restoration required. At some point, a builder may explain that the request is technically possible but not reasonable for the available budget or schedule.

How Does the Change-Order Process Work?

The exact workflow depends on the contract and builder, but Episode 12 describes a process that can be organized into these steps:

Submit the request in writing. Describe the desired outcome, location, product, and reason for the change.

Confirm feasibility. The builder reviews the construction stage, plans, site conditions, code implications, and whether design or engineering input is required.

Identify affected work. The builder traces the request through every related trade, material, inspection, selection, and completed scope.

Review a preliminary range when appropriate. A range can help the homeowner decide whether the team should spend more time developing final pricing.

Obtain final pricing and schedule information. The written change order should show the net cost or credit and the expected effect on completion.

Confirm payment or financing. The homeowner determines how the change will be funded and whether the lender must approve it.

Sign before work begins. The required parties approve the written scope, cost, and time adjustment before materials are ordered or field work proceeds.

Update the project records. The builder adds the approved change to the current plans, specifications, change log, accounting records, and trade instructions.

Verify the completed work. The homeowner and builder confirm that the installed change matches the signed document.

Fixed-Price vs. Cost-Plus Change Orders

Change orders can be used under either pricing structure, but the accounting and risk can look different. Before choosing an agreement, review Breven Homes' explanations of custom home builder contracts and how builders price a custom home. The signed agreement, not the label alone, determines how your specific project will be handled.

Fixed-price change orders

Under a fixed-price agreement, the original price applies to the defined original scope. A requested change is priced separately and added to or deducted from that amount if approved. The homeowner may receive one net price rather than every underlying labor, material, overhead, and profit component. Ask what the quoted amount includes, how credits are calculated, when payment is due, and whether the completion date changes.

Cost-plus change orders

Under a cost-plus agreement, the homeowner typically pays the actual cost of the work plus the builder fee or markup defined by the contract. Episode 12 explains that change-order costs can blend with the original project costs unless the accounting system separates them carefully. Ask whether the standard fee applies, whether complex changes carry a different administrative rate, how estimates are reconciled with actual cost, and how invoices will distinguish original scope from changed scope.

Neither structure removes the need for documentation. A cost-plus project still needs a clear scope and authorization, while a fixed-price project still needs transparency about what the change-order price includes and how the schedule will be revised.

How Do Change Orders Affect Financing and Cash Flow?

A construction loan is generally based on an approved budget and draw schedule. A change order does not automatically increase the loan amount. Depending on the lender and agreement, the homeowner may need to pay for the change directly, obtain lender approval, use contingency funds, or document the revised budget before the builder proceeds.

Before construction, ask both the builder and lender how owner changes will be funded. Breven Homes' episode on financing a custom home build provides additional context for construction loans and draw administration. Keep a running total of approved changes, payments, credits, remaining contingency, and any amount that must be provided outside the loan.

For every proposed change, confirm:

Whether the lender must review or approve the change

Whether the change is eligible to be paid through a future draw

Whether the builder requires payment before ordering or starting the work

Whether an unused allowance or approved credit can offset part of the cost

How the change affects the remaining contingency and cash needed to finish the home

How Can Homeowners Reduce Change Orders Before Construction?

No planning process can guarantee that a custom home will have zero changes. However, decisions made before construction are usually easier to evaluate and coordinate than the same decisions made after work is underway.

Review the final plans room by room

Walk through daily routines on the drawings: entering the home, unloading groceries, preparing meals, working, entertaining, doing laundry, storing seasonal items, charging vehicles, using outdoor spaces, and preparing for future accessibility needs. Episode 13 explains how homeowners can turn ideas into coordinated, buildable floor plans before construction documents are finalized.

For each room, review:

Furniture dimensions, circulation paths, door swings, and sightlines

Outlet, switch, lighting, data, television, speaker, and charging locations

Cabinetry, shelving, storage, appliance clearances, and countertop use

Plumbing fixtures, ventilation, floor drains, and hot-water needs

Windows, privacy, views, natural light, shading, and wall space

Ceiling heights, beams, soffits, registers, access panels, and specialty details

Garage equipment, electric-vehicle charging, workshop needs, and future storage

Outdoor kitchens, pools, landscape utilities, irrigation, drainage, and future structures

Complete major selections early

Selections influence framing dimensions, rough-in locations, electrical loads, cabinet drawings, countertop templates, lead times, and installation details. Choosing appliances, plumbing fixtures, windows, doors, cabinetry, tile systems, lighting, and specialty products early gives the project team time to coordinate them with the plans.

Study the specifications and allowances

Confirm the exact product, quantity, installation scope, and allowance for every important category. A low allowance can create an expected upgrade later even when the product choice feels ordinary. Review common home builder pricing concerns before treating the lowest preliminary number as the most complete proposal.

Include the builder during design

Architectural ideas should be evaluated for construction sequence, trade coordination, material availability, budget, and site conditions before they become expensive to revise. Breven Homes' process brings planning, design, selections, and pricing together before the final construction agreement so the team can reduce unresolved details entering the field.

Questions to Ask About Change Orders Before Signing

What types of changes require a formal change order?

Who is authorized to request and approve a change?

Will you perform any changed work before the document is signed?

How are pricing requests, design time, estimating time, and declined changes charged?

How are builder fees or markups calculated under this contract?

How are credits for deleted work calculated?

Will I receive trade invoices or another cost breakdown under a cost-plus agreement?

How will the schedule extension and revised completion date be documented?

When is payment due, and must the lender approve the change?

How will approved changes be added to the plans and communicated to the trades?

What happens if the requested material becomes unavailable or increases in price?

How are emergency field decisions handled when waiting would stop construction?

Questions to Ask Before Approving a Specific Change

What problem are we solving, and is there a less disruptive alternative?

Which trades, materials, plans, inspections, or completed work will be affected?

Is the price final, an allowance, or an estimate subject to actual cost?

Does the amount include design, engineering, permits, taxes, delivery, and builder fees?

Are there credits for work that will no longer be performed?

How many days will this add, and could material lead time extend the delay further?

How will this be funded, and when must payment be made?

What drawings, product information, or samples are attached to define the result?

Who will update the plans and verify the field installation?

What happens if we decide not to proceed after final pricing is prepared?

How Breven Homes Approaches Changes

Episode 12 presents change orders as a normal part of custom construction, not automatically as a failure or conflict. The emphasis is on setting expectations, identifying the cost and schedule effect, obtaining written agreement, updating the plan set, and keeping the homeowner experience organized.

Breven Homes' current custom home building process is designed to define the property, plans, selections, allowances, specifications, scope, and fixed price before construction. Its frequently asked questions also explain that changes are documented and agreed to by both parties before execution. Project-specific requirements remain subject to the signed agreement.

Frequently Asked Questions

Are change orders normal when building a custom home?

Yes. A one-of-a-kind home may evolve as the plans become a physical space and as homeowners refine priorities. The important issue is not whether a change occurs, but whether its scope, price, timing, and approval are documented before the work proceeds.

Can a homeowner make changes after construction starts?

Often, but feasibility depends on the construction stage, structural and code requirements, product availability, budget, and schedule. A builder may determine that a late change is technically possible but financially impractical or too disruptive to the agreed timeline.

Do all change orders increase the price?

No. Removing or substituting work can produce a credit, but the net credit may account for completed work, restocking, cancellation charges, design time, or other contract terms. The written change order should show the calculation and the resulting contract adjustment.

Why does a change order affect the completion date?

A change may require new design or engineering, revised permits, material ordering, trade rescheduling, demolition, inspections, or repeated work. The delay should be evaluated as part of the approval, not discovered after the change is underway.

Is a verbal approval enough for a construction change?

A verbal discussion can start the review, but the final authorization should follow the written process required by the contract. The written record should state what is changing, the price or credit, the schedule effect, and the parties' approval.

Are change orders different under cost-plus contracts?

The changed scope still needs approval, but cost-plus accounting may use actual invoices plus the contractually defined builder fee rather than one fixed change-order price. Ask how the builder separates original-scope costs from change costs and whether a different fee applies to complex revisions.

How much contingency should be reserved for changes?

There is no universal percentage that fits every project. The appropriate amount depends on the completeness of the plans and selections, site uncertainty, contract structure, lender rules, and the homeowner's tolerance for upgrades during construction. Discuss a project-specific contingency with the builder and lender before signing.

Make Every Change a Fully Informed Decision

A change order is not merely permission to perform extra work. It is the record that connects a revised design decision to its construction scope, cost, schedule, payment, and approval. Homeowners can reduce surprises by studying the plans, completing selections early, understanding the contract, keeping a realistic contingency, and refusing to proceed until the written change is clear.
