Change Order

Definition

A change order is a formal written modification to an existing contract or scope of work that documents additions, deletions, or alterations to the original project agreement, including any resulting changes to cost and timeline.


What Is a Change Order?

A change order is a contractual document that modifies the original scope of work, cost, or timeline of a project. In construction, renovation, and design projects, change orders are an expected part of the process—unforeseen conditions, client preference changes, and design refinements all necessitate formal amendments. The key is to document every change in writing before the work is performed, protecting both the contractor and the client.

When Change Orders Are Needed

#### Client-Requested Changes

The most common trigger is a client who wants to upgrade materials, add features, or modify the design after the original contract is signed. Each change must be documented with revised specifications, pricing, and timeline impact.

#### Unforeseen Conditions

During renovation or construction, hidden problems such as structural damage, outdated wiring, plumbing leaks, or code violations may require additional work that was not included in the original scope.

#### Design Modifications

Interior designers and architects frequently issue change orders when design concepts evolve, materials become unavailable, or site conditions require adjustments to the original plan.

Essential Elements of a Change Order

A proper change order includes: a reference to the original contract, a detailed description of the change, the reason for the change, the cost impact (itemized), the schedule impact, and signature lines for both parties. It should be executed before the changed work begins.
