What Is a Change Order?

A change order is a formal, written amendment to a construction contract that adjusts the scope, price, or schedule after work has already begun.

Owners and contractors use change orders to document agreed adjustments.

What Does a Change Order Typically Cover?

  • Additional or revised scope of work
  • Adjusted price for the change
  • Revised timeline, if applicable
  • Both parties’ signatures confirming agreement

Why Are Change Orders Important?

Discovering rotted subfloor during a bathroom remodel, for example, typically triggers a change order covering the extra repair cost before work continues. Verbal agreements to change scope without a written change order are a common source of payment disputes, since there’s no documented agreement on price if a disagreement arises later.

Change Order vs. Scope of Work

The scope of work defines the original agreed project; a change order modifies that original scope after the fact. Every change order effectively rewrites part of the scope of work it’s attached to.
