Do NYC DOB Permits Expire?

Yes, permits issued through the NYC Department of Buildings (DOB) in the DOB NOW: Build system do expire—and knowing when and why is crucial for contractors, property owners, and project managers.

Unlike older paper-based permits, digital permits issued via DOB NOW have built-in expiration triggers designed to ensure active oversight and compliance. A permit will expire on the earliest of three possible dates: the expiration of required insurance coverage (such as general liability, disability, or workers’ compensation), the end of a professional license tied to the permit (like a contractor’s license), or one year from the date the permit was issued.

This means even if your project timeline allows for longer work, the permit itself may lapse well before completion if supporting documents aren’t kept current. For example, if your liability insurance renews annually in June but your permit was issued in April, your coverage could end in June—automatically triggering permit expiration two months early unless you update the DOB.

Similarly, if a licensed professional—such as a design professional or contractor—lets their license lapse, the permit tied to their credentials is no longer valid. The system is designed to promote accountability and ongoing compliance, not just one-time approval.

To avoid delays or work stoppages, it’s essential to monitor all expiration dates associated with your permit: insurance, licenses, and the one-year issuance window. Renewals or updates can often be submitted through DOB NOW, but acting proactively is key.

In short, NYC DOB permits aren’t “set and forget.” They require ongoing management. Staying ahead of expiration dates keeps your project legal, safe, and moving forward without surprise interruptions.
