New York Building Permits — Complete Guide (2026)
The definitive resource for building permits across New York State and NYC
New York has two distinct permitting worlds: NYC (the most complex permit system in the US, run by DOB) and the rest of NYS (governed by the NYS Uniform Code, administered by municipalities). Heavy snow loads, coastal flood zones, and historic districts are major code drivers statewide.
How building permits work in New York
Outside NYC, building permits in New York are issued by towns, cities, and villages — not counties. Most counties have no building department. Each municipality administers the NYS Uniform Code independently. Frost depth (36–48 inches), heavy snow loads, and coastal flood zones are key compliance factors.

New York county permit guides
Most NY counties don't issue permits directly — municipalities do. These guides cover the key permitting environments in each county area.
How to get a building permit in New York
NYC or outside NYC?
This is the first and most important question. NYC (Manhattan, Brooklyn, Queens, Bronx, Staten Island) uses the NYC Building Code and DOB NOW portal. The rest of New York uses the NYS Uniform Code administered by local municipalities. The processes are completely different.
Find your municipality (outside NYC)
In New York State, permits are issued by cities, towns, and villages — not counties. Most counties have no building department. Locate your town or village and contact their building department directly. Many now have online portals.
NYC: hire a licensed professional
NYC requires licensed architects (RA) or professional engineers (PE) to file most permit applications. Electrical work must be filed by a licensed master electrician; plumbing by a master plumber. Owner-builders cannot self-file most NYC permits.
Check snow load and frost depth requirements
New York has some of the most demanding structural requirements in the US. Ground snow loads range from 30 psf (NYC area) to 70+ psf (Tug Hill Plateau, Adirondacks). Frost depth is 36–48 inches statewide. All foundation footings must be below frost depth.
Flood zone and coastal check
Post-Sandy FEMA maps significantly expanded flood zones in Long Island, NYC coastal areas, and Hudson River communities. Verify your flood zone before designing. Coastal Erosion Hazard Areas (CEHA) have additional NYS DEC setbacks beyond FEMA requirements.
Submit plans and schedule inspections
NYC uses DOB NOW for digital submissions. Outside NYC, processes vary widely by municipality. Upstate NY municipalities are generally more affordable and faster than downstate. Foundation, framing, rough-in, and final inspections are required statewide.
