The Columbus City Council approved changes to the zoning code on accessory dwelling units last month. Homeowners in residential districts can now apply to build or convert space into a second living unit on their property. The policy directly targets single-family lots across neighborhoods such as Clintonville, German Village and the Near East Side.

Why the change arrives in 2026

City planning records show the amendment responds to rising housing demand recorded in the 2025 annual growth report. Columbus added more than 8,000 residents between 2023 and 2025, according to the Mid-Ohio Regional Planning Commission. The new provisions take effect after the council vote and replace earlier restrictions that limited ADUs to only certain overlay districts.

Residents who own qualifying lots can submit plans for units up to 800 square feet. The change applies to properties zoned R-1 through R-4. Permit fees remain at the standard rate set in the 2026 building department fee schedule. Local advocates note that the process requires review by the zoning administrator within 45 days of a complete application.

Daily effects on Columbus households

Homeowners gain the option to create rental space or housing for family members without moving. A resident on the Near East Side could add a unit above a garage and list it through standard rental channels. Tenants in new units would access the same city water and sewer services already billed to the main address. The legislation states that off-street parking is not required for the additional unit.

The government projects the first permits to be issued by late 2026. The Department of Development will track completed units through its annual housing report. Property owners remain responsible for any increased property taxes calculated under the county auditor's existing assessment rules.
