How long do I have to submit a delay claim under AIA A201?
Last reviewed July 5, 2026
You have 21 days from the date of the event causing the delay to submit a claim under AIA A201. If you fail to do so, you may lose your right to compensation for that delay.
Key points
- 21-day deadline for delay claims
- Starts from the date of the delay event
- Failure to submit may waive your rights
AIA A201 requires contractors to provide written notice of delays within 21 days. This notice should include the cause of the delay and the anticipated impact on the project schedule. Missing this deadline can jeopardize your ability to claim for additional costs or time extensions.
