Rochester NY deck permit rules
Rochester's Bureau of Zoning & Permitting requires a building permit for decks attached to the house and for freestanding decks elevated more than 30 inches above adjacent grade. All applications submitted online at cityofrochester.gov. Documentation: site plan, framing plan, footing details (48-inch minimum depth), and guardrail specifications. Contact Plan Review at 585-428-6526 to confirm documentation requirements before submitting.
Rochester's 48-inch frost depth is the defining structural constraint. All post footings must bear below 48 inches — no concrete is poured before the inspector verifies depth. Standard practice: tube-form concrete piers at 54–60 inches deep. Preservation Districts (Corn Hill, Third Ward, East Avenue, Maplewood, and others) require a Certificate of Appropriateness (COA) from the Preservation Office before a building permit is issued. COA review takes 4–8 weeks — contact the Preservation Office early. NY HIC license required for contractors.
