When does the warranty period for work commence according to the Certificate of Substantial Completion?

The warranty period for work is triggered by the issuance of the Certificate of Substantial Completion. This certificate signifies that the project is sufficiently complete, allowing the owner to occupy or utilize the work. The timing of this event is crucial as it establishes a clear starting point for evaluating the warranty obligations. Warranties typically cover a set period during which the contractor is responsible for addressing any defects or issues that may arise from their work.

This approach promotes clarity between the owner and contractor regarding when to expect the warranty protections to begin, thus preventing any disputes that might arise from differing interpretations of when the work is deemed complete. The other options relate to different phases or aspects of the project timeline, but they do not reflect the formal completion status that triggers warranty liability.
