A DOB sign-off is the final approval issued by the New York City Department of Buildings (DOB) to confirm that all work on a construction or renovation project has been completed according to code and that all inspections and required documents have been properly submitted. This is the last step in closing out a building permit.

Why Is a DOB Sign-Off Important?

Without a DOB sign-off:

The permit remains open, which can affect property sales, refinancing, or certificate of occupancy (CO) issuance.

The project is considered incomplete or non-compliant.

You may incur penalties or violations for unfinished or unverified work.

Types of Sign-Offs

Final Construction Sign-Off – For general construction work.

Plumbing Sign-Off – Confirms plumbing work was inspected and approved.

Electrical Sign-Off – Issued by a licensed electrician through a separate process with the DOB Electrical Division.

Fire Department (FDNY) Sign-Off – Required for sprinkler or fire alarm systems.

Special Inspections Sign-Offs – Includes structural, energy code compliance, etc.

How to Check Sign-Off Status

You can check a project’s sign-off status using:

DOB NOW: https://www.nyc.gov/dobnow

Search by address, permit number, or job number.

Common Reasons for Delayed Sign-Off

Missing inspections or failed inspections

Open violations (e.g., ECB, HPD)
