NYC Apartment Drywall FAQ
Answers to the most common drywall and plaster questions from NYC apartment owners and renters: permits, plaster vs. drywall, co-op rules, fire ratings, and hiring contractors.
Drywall and plaster repair in New York City apartments and brownstones. Pre-war buildings, fire-rated requirements, co-op rules, and working in tight urban spaces.

Doing drywall work in New York City is a different experience than almost anywhere else. The buildings are older, the spaces are smaller, and there are rules about what you can and can't do that don't exist in most other places in the country. A straightforward bedroom repair that would take a half-day in a suburban ranch can turn into a multi-week project in a Manhattan co-op once you factor in board approval and building management requirements.
The biggest variable is the building itself. Pre-war buildings — generally anything built before about 1940 — almost always have original plaster walls. That plaster may be in good condition or it may be crumbling, and the approach to repairs is completely different from standard drywall work. Post-war buildings through about the 1980s are more likely to have original drywall, though many have been patched with materials that don't match what's there. Newer construction is standard drywall throughout.
NYC also has specific fire code requirements. Multi-family residential buildings require fire-rated assemblies in certain locations, which typically means 5/8-inch Type X drywall rather than the standard 1/2-inch. If you're doing work in a NYC apartment that involves opening or replacing walls, it's worth knowing what you're working with before you start.

Local Requirements: NYC Building Code requires permits for most wall work beyond simple patching. Multi-family buildings require fire-rated assemblies in specific locations. Co-op and condo boards typically require alteration agreements for work involving walls, ceilings, or plumbing. Always check with your building management office before starting any work beyond cosmetic repairs.

Pre-war NYC apartments still have the original plaster walls — and patching them is not the same as drywall repair. Mike Torres shares what his friend Danny learned the hard way on a Park Slope brownstone.
