What is the warranty period for a Contractor's work according to AIA A201?

The warranty period for a Contractor's work according to AIA A201 is set at one year after substantial completion. This period is crucial as it establishes the time frame during which the contractor is responsible for correcting any defects in workmanship or materials. After substantial completion, the owner is typically able to occupy and use the building, but potential issues may arise that need to be addressed. The one-year warranty is intended to protect the owner during this period, allowing them to identify and report defects, which the contractor is obligated to remedy without additional charge.

Additionally, this warranty period follows industry standards and reflects the common practice in construction contracts, providing a balance of accountability for contractors while allowing owners peace of mind during the transition to occupancy. The other options either reflect shorter periods which would not provide adequate protection to the owner or longer durations that are not standard in the AIA documents.
