Case: the change order that was never written

Lesson 12 of 19~9 minFree previewCurrent as of September 2026Leer en español

A whole-house repipe at $16,400 grows by $2,350 over nine working days: a relocated washer box, a second hose bibb, a rerouted line around a beam nobody knew was there, and an upgraded shutoff the customer asked for while standing in the garage. Every addition was requested, every addition was agreed to, and every addition was verbal. At the final, the customer pays the contract price and disputes the rest, holding a signed notice that says an unwritten change order is not enforceable against her. This case follows the four changes to the final invoice, the small claims hearing, the CSLB complaint that came out of it, and the nine days as they would have gone with a change-order pad in the truck.

What the full lesson covers

  • Four verbal changes worth $2,350 became four unenforceable claims the moment the customer chose to dispute them, because the contract she signed said so (7159(e)(3)).
  • The "unjust enrichment" sentence got the contractor a small claims hearing and $1,100 of the $2,350, less a day of lost work, after a judge heard both sides guess at the value.
  • The complaint to CSLB was not about the money; the investigator cited the missing change orders under 7159(a)(5) because the missing paper was a violation whether or not the customer paid.
  • The final release the customer demanded carried a blank for "disputed claims for extras"; the contractor left it blank and released the extras he was still fighting over.
  • Three minutes per change, on the pad, before the work, would have produced four signed documents and a final invoice with nothing to dispute.
