Deck Construction Permits in Columbus
Local Rule
Columbus Building and Zoning Services
Columbus follows the statewide RCO exemption: a freestanding deck 200 square feet or less, 30 inches or less above grade, not attached to the house and not serving a required exit door needs no permit; an attached deck needs one regardless of size, since it fails the "not attached" condition. The city requires a site plan, construction drawings with dimensions and structural details, and foundation specifications including footing depth, processed through its online portal. Central Ohio's frost depth runs 32 to 36 inches. A real administrative quirk: Ohio has no statewide contractor license, and the Columbus metro has more separate city registration offices than anywhere else in the state, so a contractor working across Columbus, Upper Arlington and Dublin must register separately with each.

How This Compares to Franklin County
Columbus's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:
Franklin County Building Dept / City of Columbus
Franklin County (Columbus) works under the 2019 Residential Code of Ohio (RCO), a statewide code, Section 102.10(9) exempts small decks and Section 507 governs deck construction. A building permit is required once a deck exceeds the small-deck exemption, and because most decks are attached and over 30 inches, most need a permit. The distinctive Columbus rule is separate from the building permit: the City of Columbus requires ZONING approval for any deck exceeding 169 square feet, regardless of height or whether it is attached, to confirm setbacks, lot coverage, and easements. A defining climate factor: Ohio's frost depth in the Columbus area is 32 inches, so all deck footings must reach at least 32 inches below finished grade, the footing inspection happens after post holes are dug to frost depth and before concrete. The post must bear on a minimum of 6 inches of concrete (Table 507.3.1). Framing plans must show ledger size and bolting method, joist size/span/spacing, and beam size a
