Change orders are the formal way we capture any change to the originally agreed scope, drawings, or specifications after construction has begun on your lot. On custom homes we design and build, change orders commonly arise from owner-driven design refinements (moving a wall, upgrading finishes, adding built-ins), unforeseen site conditions (rock, grading complications, utility relocations), or adjustments required by permitting or engineering. Because each change affects materials, subcontractor schedules, and often municipal approvals, we treat them as contractual amendments rather than informal promises — documented with a clear description, cost breakdown, and schedule impact before work proceeds.
Our process is designed to be fast and transparent. When you request a change or we identify a condition that requires one, we prepare a written change order outlining the scope, line-item costs (materials, labor, subcontractor adjustments), any applicable allowances being reconciled, our standard markup, and the expected time extension. You’ll receive that estimate for review; once signed, the change order becomes part of the construction contract and is billed either as an add-on to the next draw or as a separate invoice depending on timing. For site-driven changes that affect permits or engineered work we include any necessary resubmittal fees and clarify whether the change will trigger a permit revision or additional inspections.
To keep change orders from derailing budget or schedule, we recommend making as many finish and layout decisions as possible during design and selections, maintaining a contingency line in your budget, and using our regular selection appointments to lock allowances. We also provide unit pricing for common items where practical, so you can make quick, informed decisions in the field without open-ended cost surprises. Our goal is to manage changes efficiently: documented approvals, clear cost allocations, and schedule updates so you always understand the impact on your custom home’s completion on your lot in the Denver area.
What is a change order and what types might I encounter during custom home construction?
A change order is the written amendment to your construction contract that records any work, material, or scope change after the original agreement is signed. From our experience, a legitimate change order always describes exactly what will be added or removed, notes any immediate impacts on price or schedule, and becomes part of the contract documents so there’s no confusion later. Verbal directions are common on job sites but don’t substitute for the formal change order you’ll want in writing before work proceeds.
Change orders fall into a few practical categories you’ll see on a custom home: owner‑requested upgrades or design changes (moving a wall, changing cabinetry or fixtures), designer/architect revisions (redrawn plans that change scope), unforeseen site conditions (hidden rock, buried debris, or concealed structural issues), inspector or code‑required corrections, and material substitutions or availability issues. They also range in scale from small “field changes” (a light moved a foot) to major scope changes (adding a room or changing foundation type), and each type is handled differently in how we price and schedule the work.
To manage them efficiently, follow a couple of builder-tested practices: make as many finish and layout decisions as possible before construction starts; when you request a change, ask for a written change order that lists scope, a clear price or estimate, and the expected schedule impact before any work begins; and group small requests when practical to avoid repeated mobilization and setup costs. We maintain a running log of all change orders and will provide itemized descriptions so you can see exactly what changed from the original contract — that transparency is the simplest way to avoid surprises.
How much will a change order cost, and how are allowances, pricing methods, markups, and contingencies handled?
As your builder I price change orders in one of three ways depending on the scope: a lump-sum fixed price for a clearly defined scope, time-and-materials (T&M) when the scope is uncertain, or unit pricing for repetitive items (e.g., per linear foot of trim). Allowances are placeholder dollar amounts in the contract for items you haven’t selected yet — when you pick a product that costs more than the allowance we issue a change order for the overage (and if it costs less you get a credit). To avoid surprise costs, get realistic allowances at the start and ask for ballpark quotes so you know whether an allowance needs to be increased before workmanship or long-lead purchases begin.
Most builders add a markup to subcontractor and material costs on change orders to cover project overhead, coordination time, and warranty exposure; in our market that markup typically ranges from 10–18% depending on how involved the change is. Expect additional line items when applicable: sales tax, permit amendment fees, engineering or inspection costs, and any restocking or freight charges. Always request a line-item breakdown on the change order showing subcontractor labor, materials, tax, permit costs, and the builder’s markup so you can compare proposals or seek multiple estimates — opaque single-number change orders are the easiest way for costs to escalate unnoticed.
Plan a contingency in your project budget specifically for change orders and unknowns: for most Denver custom homes I recommend 8–12% of construction cost (use 5% for very well-defined builds, 12–15% for highly customized designs or remodels with hidden conditions). To keep change order spending under control, finalize selections early, get firm “not-to-exceed” quotes when possible, batch non-urgent changes so we minimize remobilization and ordering fees, and require written change orders with a clear price and scope before work or purchases begin.
Who must sign a change order and how long will approval take?
As your builder, we require every change that affects scope, price, or schedule to be documented on a written change order and signed by the homeowner and an authorized representative of the builder before work begins. If your contract names an architect, interior designer, or HOA as part of the approval chain, their sign-off is also required for items in their scope; subcontractors typically do not sign the change order but their pricing and schedule impacts will be attached. Never accept or rely on verbal approvals — they create disputes. If you want someone else (spouse, agent, designer) to approve on your behalf, provide written, dated delegation in advance so we can accept their signature without delay.
Expect response and turnaround windows to be stated in your contract; typical timelines for pricing a straightforward change are 3–10 business days, but complex items or long‑lead materials can take longer. For expedited or emergency changes we can act faster, but you should expect an acceleration premium and immediate partial payment for materials and labor to secure priority scheduling. We also require homeowners to return signed change orders within an agreed window (commonly 7–10 days); if you miss that window we may hold pricing, delay ordering, or proceed with the original plan to avoid site disruption — either outcome can increase your cost.
Who can authorize a change in practice matters because approvals trigger purchase orders, subcontractor schedules, and lien exposure. Lenders often require homeowner signatures for financed extras, and an unauthorized signature from someone who lacks written delegation can expose you to extra charges or lien risk. Practical steps: confirm the builder’s authorized signer in the contract, name a single homeowner contact to speed decisions, insist every change order include the exact cost, payment terms, and schedule impact, and keep dated copies. If you and the builder disagree, stop work only on the affected portion and document the dispute in writing so there’s a clear record while issues are resolved.
How will a change order affect my construction schedule, lead times, and possible acceleration costs?
A change order can move trades and inspections around on the critical path and create downstream gaps where work cannot proceed. If the change affects framing, structure, envelope penetrations, or main mechanical runs, we often have to pause one sequence until the change is resolved — that pause converts into a measurable delay because electricians, plumbers, and drywall crews are scheduled tightly. When you request a change, insist we provide a revised schedule that shows which milestones shift, which activities become critical, and an estimated number of calendar days lost so you can see the real impact on move-in and financing deadlines.
Long-lead items are the most common drivers of multi-week delays: windows, custom cabinetry, specialty doors, stone, and certain appliances or HVAC equipment frequently have manufacturer lead times that range from 4–16 weeks. If the change means re-specifying an item we’ve already ordered or committed, you’ll likely face new lead times plus restocking or cancellation penalties. Before you sign a change order, ask us to confirm current supplier lead times in writing and whether any orders must be cancelled and reordered — that information determines whether the delay is days or months.
If you need the project back on the original timeline, acceleration is possible but not free. Typical acceleration costs include overtime premiums for crews (often 1.5x–2x hourly rates), weekend mobilizations, expedited freight for materials, additional supervisory time, and sometimes fees to rebook inspections. We will provide a line‑item acceleration quote and an updated schedule showing the new, guaranteed dates and the cost to achieve them. A practical approach is to accelerate only the activities on the critical path, get written acceptance of who pays for acceleration, and freeze scope changes during the acceleration window so the new dates hold.
What contract clauses, notice requirements, and documentation should I include to prevent and resolve change order disputes on my custom home?
From my experience building custom homes in the Denver area, the single most important contract clause is a strict “written change order only” requirement that defines what constitutes a valid change. That clause should require a signed, dated change order form that includes a clear scope of work, references to the original contract pages or line items, and an explicit statement of any schedule impact. Also include a concealed-conditions/latent-conditions clause that spells out how unforeseen site conditions will be handled (notice timeline, who obtains bids, and how costs are documented), and a suspension/stop-work clause that allows either party to pause work for safety, nonpayment, or unapproved changes until the issue is resolved.
Documenting every change so it can be traced back is the practical defense against disputes. Require that each change order include itemized pricing (with backup vendor quotes or subcontractor bids attached), a projected change to the completion date, and any alternates or allowance adjustments noted. Keep a running change order log that we update weekly and provide to you—this log should show original contract value, incremental changes, cumulative total, and paid/unpaid status. For verbal or emergency directives, insist on a short written confirmation window (typically 24–72 hours) that converts the verbal instruction into a formal change order or records the reason the work proceeded under a temporary authorization.
Even with good paperwork, disagreements happen; the contract should prescribe a practical, staged dispute-resolution process. I recommend requiring an initial meet-and-confer within a fixed short window, followed by non-binding mediation, and only then arbitration or litigation if necessary—this saves time and cost and keeps the project moving. Include a timeline for submitting formal claims (so issues don’t languish) and a clause allowing neutral third‑party cost or schedule assessment (an independent estimator or an architect) to provide an impartial baseline. Finally, maintain copies of all communications, invoices, delivery tickets, photos, and field reports—these are what an arbitrator or mediator will want to see, and they usually resolve disputes far faster than relying on memory or informal notes.
