Custom Home Change Orders: How They Should Work
A change order is not merely a price. It is a documented change to scope, money, time, and responsibility.
Changes are common in custom construction, but unmanaged changes create some of the most painful disputes. An owner request, design refinement, concealed condition, code response, product discontinuation, or field conflict can affect multiple trades and the schedule. A disciplined process identifies the reason, evaluates alternatives, calculates direct and indirect effects, secures approval, and updates the contract documents before work proceeds whenever practical.
At a glance: Classify the change, document the source, define scope, price direct and related work, calculate fee and time, obtain required approvals, update documents, and track cumulative impact.
Classify why the change exists
Owner change, design error or omission, code or authority requirement, unforeseen condition, substitution, value-engineering option, allowance reconciliation, and builder means-and-methods issue may carry different responsibility. Classification should be based on facts and contract terms rather than blame language. The team can solve the problem more effectively when the source and governing documents are clear.
Describe complete scope and alternatives
A request such as “move the wall” may affect structure, electrical, HVAC, flooring, trim, cabinetry, paint, permit drawings, and adjacent rooms. The proposal should show what is added, removed, relocated, repaired, and excluded. Where practical, present alternatives with different cost or schedule outcomes. Sketches, revised drawings, samples, and product data should be attached.
Calculate money and time transparently
Show labor, material, equipment, subcontractor cost, tax, freight, restocking, design and engineering, supervision, general conditions, fee, and credit. Explain how markup is applied under the contract. Identify schedule impact, procurement effect, resequencing, and decision deadline. A change with no stated time effect may still delay work if approval arrives after a trade has mobilized.
Require authorization before changed work
Define who can approve changes and whether lender consent is required. Verbal field direction should be documented immediately. The contract should address emergencies, disputed work, time-and-material tickets, and not-to-exceed authorization. Trades and site staff should not accept scope changes from unauthorized family members or consultants.
Update the entire project record
An approved change should update contract sum, completion date, budget forecast, drawings, specifications, schedule, selections, procurement, and decision log. Track pending changes and potential exposures separately from approved changes. Cumulative impact can be substantial even when individual changes feel small.
The Builder Concierge point of view
Builder Concierge makes changes visible across design, budget, schedule, and approvals. The platform’s decision record should show what changed, why, who approved it, and what it affected, preventing the same change from being interpreted differently by owner, builder, and designer.

Frequently asked questions
Can a builder proceed without a signed change order?
Contracts often address emergencies, field directives, time-and-material work, and disputed conditions differently. The safest practice is clear written authorization under the agreed process; obtain legal advice for disputes.
Why do change orders include markup?
Contracts may permit builder fee, overhead, supervision, insurance, and other costs on changes. The basis and percentages should be defined before construction.
Can a change order reduce the price?
Yes. Deletions or lower-cost scope may create a credit, adjusted for actual savings, restocking, committed work, redesign, and contract terms.
How can I reduce change orders?
Complete site investigation, coordinated design, selections, constructability review, and owner decisions before construction. Some unforeseen conditions and legitimate improvements may still occur.
