Before You Build in Columbus, OH: Permit & Rule Checklist (2026)

All residential swimming pools deeper than 24 inches in Columbus must be enclosed by a barrier at least 48 inches high with self-closing, self-latching gates. The requirement comes from the Ohio Residential Code, Appendix G, and is enforced by Columbus Building and Zoning Services.

Ohio has no Good Neighbor Fence Act for residential properties. ORC §971.02 covers agricultural partition fences only. Boundary disputes resolved through common law.

Columbus allows fences up to 6 feet in side and rear yards without a building permit. Fences over 6 feet require a permit and setback compliance. Front yard fences are restricted by vision clearance requirements. Columbus City Code §3321.05.

Columbus enforces residential pool barrier rules through the Ohio Residential Code (OAC 4101:8) Appendix AG, which adopts IRC Appendix G/AG105 and applies to any pool, hot tub, or spa with water depth greater than 24 inches. Barriers must be at least 48 inches high with no openings allowing a 4-inch sphere to pass. Gates must open outward and be self-closing and self-latching, with the release mechanism at least 54 inches above the bottom of the gate. The Columbus Department of Building and Zoning Services issues pool permits and inspects barrier compliance.

Columbus passed Ordinance 2526-2025 (effective late 2025) amending Title 33 (Zoning Code) to allow Accessory Dwelling Units (ADUs) by right in all residential and apartment districts (Chapters 3332 and 3333). The ordinance removes most variance hurdles, exempts ADUs from added parking, frontage, and lot-width requirements, and permits internal (basement/attic), attached (above garage), and detached ADU types. ADUs must remain clearly accessory and subordinate in scale to the principal dwelling.

Columbus permits tiny homes on permanent foundations as standard single-family dwellings if they meet the Ohio Residential Code minimums, including Appendix Q small-dwelling provisions. Tiny homes on wheels are treated as recreational vehicles and are not allowed as permanent residences on residential lots.

Columbus regulates sheds as accessory structures under Title 33 Zoning Code §3332.38 (Private garage). Sheds 200 square feet or larger require a building permit under the Residential Code of Ohio. Accessory structures must be located in the rear yard, set back at least 5 feet from side and rear property lines, separated from the principal dwelling, and may not exceed 30% rear-yard coverage in residential districts.

Columbus permits fire pits meeting commercial standards with screen top or chimney. Must maintain 15-foot setback from structures. Open-flame fires limited to clean seasoned firewood or natural gas. Smoke complaints can result in forced extinguishment.
