Getting a construction permit in New York City is a multi-step process that can be straightforward for minor work or incredibly complex for major projects. This guide walks through the process for the most common scenarios.
Do You Need a Permit?
In NYC, most construction work requires a DOB permit. This includes:
- Any structural changes (moving walls, adding floors)
- Plumbing work beyond minor repairs
- Electrical work (separate DOB electrical permit)
- HVAC installation or major repair
- Facade alterations
- Change of use
- Demolition of any kind
Work that typically does NOT require a permit: cosmetic painting, wallpaper, replacing fixtures (same location), minor carpentry that doesn't affect structure, replacing appliances.
Step 1: Hire a Design Professional
Most DOB filings require plans prepared by a New York State Registered Architect (RA) or Professional Engineer (PE). They will:
- Assess the scope of work
- Prepare construction drawings
- Determine the appropriate job type (NB, A1, A2, A3)
- File the application with DOB
Step 2: File the Application
Applications are filed through DOB NOW (for eligible job types) or through the traditional paper/BIS process. The filing includes:
- PW1 form (Plan/Work Application)
- Construction drawings and specifications
- Zoning analysis
- Energy code compliance (ComCheck or equivalent)
- Applicable fees
Step 3: Plan Examination
DOB reviews the plans for code compliance. Two paths:
- Professional Certification: The architect/PE certifies compliance, and DOB issues approval quickly (1-3 days). Available for eligible project types.
- DOB Examination: A DOB plan examiner reviews the plans. May result in objections requiring revised plans. Timeline: 2 weeks to 6+ months depending on complexity.
Step 4: Obtain the Permit
Once plans are approved, the contractor obtains the work permit. Requirements:
- Licensed contractor with current DOB registration
- Valid insurance certificates
- Safety plan (for certain work types)
- Permit fees paid
Step 5: Construction and Inspections
During construction, DOB conducts inspections at required milestones. The permit holder must:
- Post the permit prominently at the job site
- Request inspections at required stages
- Maintain construction documents on site
- Comply with all conditions of approval
Step 6: Sign-Off
After construction, the design professional certifies completion. Depending on the job type, you may need:
- Letter of completion (LOC) — most alterations
- Certificate of Occupancy — new buildings and A1 alterations that change use
- Temporary Certificate of Occupancy (TCO) — while minor items remain outstanding
