Deck Construction Permits in Buffalo

Local Rule

City of Buffalo Permit and Inspection Services

The city's own guidance confirms any deck attached to the home, or any freestanding deck more than 30 inches above grade, requires a building permit from Buffalo's Permit and Inspection Services office; a specific small-deck square footage exemption was not confirmed directly for the city. A distinctive local layer: a deck in one of Buffalo's historic districts may need additional review from the Preservation Board if it is visible from the street. Western New York frost depth runs about 42 inches, among the deeper requirements in the state.
