What requires a permit, what is exempt, and how the Residential Code of Ohio applies to outdoor living projects in Licking County — New Albany's east side, Granville, Pataskala, and Johnstown. Reviewed August 2026.
Ohio's Residential Code (RCO) sets the baseline: permits are required for attached decks, roofed structures, and detached buildings of 200 square feet or more — one-story detached accessory structures under 200 square feet are exempt, including from frost footings. Pools holding more than 24 inches of water require a permit and a 48-inch barrier under Ohio Revised Code 3781.102, with self-closing, self-latching gates latched at least 54 inches above grade. The Licking County Building Code Department serves most of the county; New Albany and some municipalities handle their own — and with the Intel-driven growth wave, permit offices here are busier than they have ever been. Complete plans matter more than ever.
At-grade paver and concrete patios are flatwork — generally no building permit, though setbacks and drainage apply, and New Albany's architectural standards add their own review layer. Anything structural bears below Ohio's 32-inch frost line, and retaining walls over four feet from the bottom of the footing typically require a permit and engineering.
Attached decks require a permit and inspections — frost-depth footings, ledger attachment, and guardrails. A detached one-story accessory structure under 200 square feet is exempt; a pavilion or pergola built for living space, attached to the home, or carrying electrical, gas, or a motorized louvered roof should be planned as permitted, engineered work. Allscape submits stamped engineering with every motorized pergola application.
