Queens County, NY Permit Requirements: Renovation Permits (2026)

New York City has among the strictest permit requirements in the nation for home renovations. The DOB categorizes alterations into three types: Alteration Type 1 (major changes affecting exits, occupancy, or structural elements), Alteration Type 2 (multiple work types like plumbing and electrical), and Alteration Type 3 (minor, single work type like plumbing only). All alteration types require plans filed by a registered architect (RA) or licensed professional engineer (PE), except for certain Minor Alterations that may be filed without professional certification. Work exempt from permits includes: painting, plastering, minor plumbing repairs (like replacing a faucet without changing pipe location), installing kitchen cabinets, flooring, and tile work that does not modify walls or wet areas. Work requiring permits includes: any structural modifications, electrical work (all electrical work must be performed by a licensed electrician), plumbing work (modifications or new installations), HVAC installation or replacement, window or door replacement that changes opening size, kitchen and bathroom renovations involving plumbing or electrical changes, and any addition of habitable space. In Queens, common renovation scenarios include gut renovations of pre-war housing stock in neighborhoods like Astoria, Woodside, and Jackson Heights; additions to single-family homes in eastern Queens; and conversions for compliance with accessibility requirements. DOB plan review timelines vary: Professional Certification (self-certification by the architect/engineer) is the fastest track. Standard review takes 4–8 weeks. Queens has its own DOB borough office for permit processing at 120-55 Queens Boulevard, Kew Gardens.
