What is a defects liability period in construction?
Last reviewed July 5, 2026
A defects liability period is the time after project completion where the contractor is responsible for fixing any defects. It usually lasts from 12 to 24 months, depending on the contract. During this time, the principal can request repairs without extra cost.
Key points
- Defined timeframe for defect repairs.
- Usually 12 to 24 months long.
- Contractor covers costs for defects.
The defects liability period starts once the project is completed and handed over. During this time, the contractor must fix any issues that arise, like faulty workmanship or materials. It's a way to hold the contractor accountable after the job is done, ensuring the work meets the required standards.
