Filing for a building permit in New York City involves fees, processing time, and regulatory hurdles that can surprise first-time filers. This guide covers what to expect in 2026.
Types of NYC Building Permits
- New Building (NB): New construction from the ground up
- Alteration Type 1 (A1): Major alterations that change use, egress, or occupancy
- Alteration Type 2 (A2): Multiple work types not affecting use or egress
- Alteration Type 3 (A3): Minor alterations — one type of work (plumbing, electrical, etc.)
- Demolition (DM): Full or partial demolition
Permit Fee Structure
DOB permit fees are based on construction cost:
- Filing fee: Varies by job type. NB and A1 jobs start around $200-$500 plus per-unit and per-square-foot fees
- Plan examination fee: Typically 20-30% of the filing fee
- Inspection fees: Included in most permit fees
- DOB NOW fees: Some job types have specific digital filing fees
For a typical apartment renovation (A2), expect $1,000-$5,000 in DOB fees. For new construction, fees can range from $10,000 to $100,000+ depending on building size and complexity.
Processing Timeline
Processing times vary significantly by job type and complexity:
- Professional Certification: 1-3 days. A registered architect or PE certifies the plans, bypassing DOB plan examination. Fastest option for eligible projects.
- DOB NOW filings: 2-4 weeks for straightforward alterations
- Standard plan examination: 4-8 weeks for simple projects, 3-6 months for complex ones
- New Building applications: 6-12 months from filing to permit issuance
Common Delays
- Objections: DOB plan examiners raise objections requiring revised plans. Each cycle adds 2-4 weeks.
- Landmarks: Properties in historic districts require LPC approval before DOB filing
- Zoning issues: BSA variances or special permits can add 6-12 months
- Other agency approvals: FDNY, DEP, DOT may require separate approvals
Expediting Options
Licensed expeditors (professional filers) can navigate the DOB system more efficiently. They know the processes, relationships, and common pitfalls. A good expeditor can shave weeks off processing time, especially for complex filings.
