Framing a backyard deck: fresh lumber and a nail gun on new decking

Requirements and size thresholds for deck permits vary by locality. The table below compares what each New York county or city requires. Always confirm with the local office before starting.

Comparing states? See deck permit rules across every locality we cover.

The application steps and inspection sequence for deck permits come from the model code rather than from New York law, so they read the same wherever you build. We keep that walkthrough in one place: how a deck permit application and its inspections work, start to finish. What changes between New York jurisdictions is below: who requires a permit, what they charge, and which office you file with.

Rochester Conditional height of the deck surface above grade Confirmed on official page
Town of Brookhaven Conditional deck rising more than eight inches above grade at any point Confirmed on official page
Town of Hempstead Yes Not specified Confirmed on official page

What a deck permit costs in New York

4 New York jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.

Buffalo

Residential building permit fee schedule: additions, alterations and repairs to residential structures are charged at $5 per $1,000 of construction cost with a $50.00 minimum, on top of the $25.00 application fee, plus a plan review fee of 20% of the permit fee with a $25.00 minimum if the work requires plans. EFFECTIVE 7/1/2025.
