A Change Order Changes the Agreement

A change order is a written modification to the construction agreement. It may add, remove, or revise work and may affect price, schedule, materials, responsibilities, or other contract terms. The original contract and approved plans remain the baseline; the change order records the specific departure from that baseline.

Why Change Orders Occur

A change does not automatically mean that someone made a mistake. Renovation work involves existing conditions, evolving decisions, and coordination among many parties. Common sources include:

  • A homeowner requests different or additional work.
  • Demolition reveals a condition that could not reasonably be evaluated earlier.
  • A specified product becomes unavailable and a substitute is selected.
  • A design detail is revised or clarified after construction begins.
  • An inspector, utility, engineer, or code requirement creates additional work.
  • The team identifies an omission, conflict, or coordination issue in the project documents.

Start with the Contract Process

Before construction begins, understand who may request a change, who prepares the price, who has authority to approve it, and whether work can proceed before written approval. The contract should also explain how markups, time extensions, allowances, credits, and disputed changes are handled. If the language is unclear or the issue is disputed, obtain appropriate professional or legal guidance rather than relying on assumptions.

What a Complete Change Order Should Explain

  • Scope: exactly what work is being added, removed, or revised.
  • Reason: what created the need for the change.
  • Price: the added cost, credit, or method used to determine the amount.
  • Schedule: any added time or effect on upcoming milestones.
  • Approval: the required signatures or written authorization and date.

Review the Scope Before the Price

A price cannot be evaluated well if the proposed work is vague. Confirm what is included, what is excluded, which materials or finishes are assumed, and whether demolition, disposal, design, permits, supervision, protection, patching, and related trade work are covered. A low price with missing scope may become more expensive later.

Understand the Price

The appropriate level of detail depends on the contract and the size of the change. For a meaningful cost, ask for enough information to understand labor, materials, subcontractor costs, taxes, contractor markup, credits, and applicable allowances. The goal is not to challenge every dollar; it is to confirm that the amount corresponds to the scope and follows the agreed pricing method.

Evaluate the Schedule Impact

A change can affect more than its installation time. It may require revised drawings, engineering, permit review, material procurement, trade resequencing, or rework. Ask whether the change affects a milestone or the critical path, when the decision must be made, and whether approving it later would create a larger delay.

Allowances Are Not Automatically Change Orders

An allowance is an amount carried in the contract for an item that was not fully selected or priced when the agreement was signed. The final selection may create an allowance reconciliation—a charge or credit based on the contract terms. A separate change order may still be needed when the selection changes labor, scope, quantities, supporting work, or schedule. Review both the allowance and the related scope instead of looking only at the product price.

Do Not Rely on Verbal Approval

Jobsite conversations are useful for identifying options, but they are easy to remember differently. A casual statement such as “go ahead” can create uncertainty about cost, scope, or authority. Follow the contract's written approval process before changed work begins, except when an immediate safety or property-protection response is required. Document emergency decisions as soon as practical.

Track the Cumulative Effect

A series of individually reasonable changes can materially alter the project. Maintain a current change-order log showing requested, pending, approved, rejected, and completed items. Track the original contract amount, approved additions and credits, current contract value, payments, schedule adjustments, and any unresolved proposals. Pending changes should be considered in budget forecasts even before final approval.

Separate Must-Do Changes from Optional Choices

When several changes arise at once, classify them. Some correct unsafe conditions, code issues, or concealed damage. Others protect the intended design or performance. Still others are upgrades that may be desirable but optional. This distinction helps homeowners prioritize contingency funds and make deliberate tradeoffs.

A Practical Review Process

  • Confirm why the change is needed and who requested it.
  • Compare the proposed scope with the original contract and documents.
  • Identify reasonable alternatives, including leaving the work unchanged when feasible.
  • Review the full cost, credit, and schedule effect—not only the visible item.
  • Ask questions and resolve unclear assumptions before approval.
  • Approve, reject, or revise the proposal in writing and update the project records.

Coach's Perspective

The most difficult change orders are often not the largest ones; they are the ones homeowners feel pressured to approve without enough context. Construction may be waiting, walls may be open, or a crew may need an answer. Ask the project team to identify the decision deadline and the consequence of waiting. That creates space to evaluate the change without pretending every decision can remain open indefinitely.

Questions to Ask Before Approving a Change

  • What changed from the original scope, and why?
  • Is this work required, recommended, or optional?
  • What alternatives were considered, and what are their tradeoffs?
  • Does the price include all related labor, materials, patching, and markups?
  • Is there a credit for work or materials no longer being provided?
  • How will this affect milestones, completion, and other pending decisions?
  • When must I decide, and what happens if I do not approve it?

Common Misconceptions

Every change order means the contractor made an error. Changes may result from homeowner requests, concealed conditions, product availability, design coordination, or outside requirements as well as errors or omissions.

A small change will have a small impact. The visible work may be minor while the supporting design, procurement, trade coordination, rework, or schedule effect is significant.

Verbal agreement is enough if everyone understands the request. Written documentation protects all parties by confirming scope, cost, schedule, and authorization.

Foundation Tip

Keep one decision-ready change log and review it during every project meeting. For each open item, record the owner, status, estimated cost, decision deadline, and potential schedule effect. This makes pending exposure visible before it becomes a budget or timeline surprise.

Closing Thought

Change orders are most manageable when they are treated as informed project decisions rather than interruptions. A consistent written process, clear scope, complete cost and schedule information, and an updated project forecast help homeowners adapt while protecting the renovation's larger goals.
