Building permits in Rockland County, New York
Find the right authority before you build. Rockland County permitting follows New York law — here is exactly who issues the permit and where to start.
Cities issue permits
Town, city and village building departments (Rockland County’s Buildings & Codes handles county licensing, not residential permits)
Rockland County does not issue residential building permits through a county building department. Permits are issued by the towns, cities and villages (e.g., Towns of Clarkstown, Orangetown and Ramapo, and villages such as Spring Valley and Nyack). The county’s Buildings & Codes department runs county licensing programs (e.g., home-improvement contractor licensing and trade examination boards) rather than residential permitting.
