What Is a Construction Change Order and When Should You Accept One in San Jose?

Quick Answer: A construction change order (CO) is a written amendment to your original contract that specifies additional work, removed work, or a change in materials, along with the associated cost impact and schedule impact. Change orders are normal and inevitable in construction — hidden conditions (rot behind walls, undersized electrical panels, poorly graded subfloor) discovered during work legitimately require a change order. You SHOULD accept a change order if: (1) the work described is genuinely necessary and wasn’t reasonably discoverable before the project started; (2) the price is fair (you can request itemized materials and labor costs); (3) it’s in writing. You should QUESTION or REJECT a change order if: the contractor is adding scope that was already implied by the original contract, the pricing seems inflated without justification, or the contractor refuses to provide written documentation before proceeding.

Common Legitimate vs. Suspicious Change Orders in San Jose Construction

Change OrderLegitimate or Suspicious?
Rotted sheathing discovered behind existing sidingLegitimate — hidden condition not visible before demo
Knob-and-tube wiring discovered during opening wallsLegitimate — hazard requiring code upgrade
Subfloor found to be uneven beyond spec during flooring removalLegitimate if significant; verify with measurements
Owner-requested upgrade (higher-end tile, larger window)Legitimate — owner changed scope
Permit inspector required additional structural bracingLegitimate — inspector-required change
“We need more money for labor” after project is underwaySuspicious — vague, not tied to specific changed scope
Existing item not explicitly listed in contract as “included”Suspicious — check if it was reasonably implied by the scope
Contractor claiming change order is needed for work already begunVery suspicious — work should not proceed without written CO
