Full Breakdown
Columbus City Codes § 3332.18(C), in Chapter 3332's residential-district rules under Title 33 Zoning, caps building coverage at 50 percent of lot area: no dwelling, 'alone or together with any other building or roofed structure,' may occupy more than half the lot, and the same 50 percent cap applies to manufactured homes. The limit governs R-rural, R-1 through R-4, R-2F, LRR, RRR, RR, SR and MHD districts under the long-standing Title 33 code. Columbus also adopted a 2024 Zoning Code (Title 34), effective July 30, 2025, that applies in designated corridor areas and may set different coverage standards there.
Violations & Fines
Violating the coverage cap is a first-degree misdemeanor under Columbus City Codes § 3305.99; each day the violation continues counts as a separate offense with its own penalty.
