Full Breakdown
Suffolk County enforces the New York State Uniform Fire Prevention and Building Code only for buildings it owns, under authority the state's Executive Law gives counties for county-owned structures built or altered after January 1, 1984. Under Code § 344-2, a permit for that county-building work is issued by the Department of Public Works and the Fire Marshal's Office after review, with narrow exceptions like minor repairs and small farm buildings. The county runs no comparable permit office for private property: Suffolk's ten towns and their incorporated villages, not the county, issue building permits for homes and businesses.
Violations & Fines
Starting county-building work without the Chapter 344 permit lets the Department of Public Works or Fire Marshal's Office halt it. This law reaches only county-owned buildings; unpermitted private construction is enforced by your town or village code office instead.
