Step-by-step
Determine the Permit Type
Identify which permit type you need: NB (New Building), A1 (Major Alteration), A2 (Multiple Work Types), A3 (Minor Alteration), or DM (Demolition). The scope of work determines the filing type and required documents.
Hire a Licensed Professional
Most permit applications require a licensed Professional Engineer (PE) or Registered Architect (RA) to prepare and file the application. They are responsible for the design and for certifying compliance with the Building Code.
Prepare Required Documents
Gather required documents including architectural drawings, structural calculations, zoning analysis, energy code compliance, site safety plan (for certain projects), and owner authorization. Requirements vary by project scope.
File Through DOB NOW
Your PE or RA files the application through DOB NOW Build at a810-dobnow.nyc.gov. They submit the job filing, upload plans and supporting documents, and pay the filing fee. The system assigns a job number for tracking.
Respond to Examiner Objections
DOB plan examiners review the filing and may issue objections requiring changes or additional information. Your professional responds to objections through DOB NOW. This back-and-forth continues until the filing is approved.
Obtain the Work Permit
Once the job filing is approved, you can pull the actual work permit. The permit must be displayed at the job site. Work cannot begin until the permit is active. Post the permit in a visible location.
