Akron, OH Accessory Structures: ADU Permits (2026)

An Akron homeowner pursuing a second dwelling unit on a single-family lot today works within several overlapping frameworks. First, Title 15 Chapter 153 (legacy zoning code) classifies most residential property as Class U1 (single-family) or U2 (two-family) districts. A second self-contained dwelling generally requires the lot to sit in a U2 or higher district that already permits two-family use, or for the property to obtain a variance or conditional use approval from the Board of Zoning Appeals under Article 11. Article 5 Section 153.260 governs accessory structures (detached garages, sheds, in-law suites without a full second kitchen) — it permits accessory structures customarily incident to U1, U2, UD, or UHD uses, but a fully independent dwelling with its own kitchen and bath traditionally is not 'accessory' under this section. Second, the city adopted a Form-Based Zoning Code on March 11, 2024 (approved by Council, layered onto Chapter 153) that establishes transect zones with more permissive missing-middle housing standards in designated corridors and neighborhoods. Third, the Ohio Building Code (OAC 4101:8, adopting the 2019 Residential Code of Ohio) governs construction; permits are issued by the Akron Building Inspection Division. Fourth, the Ohio Fire Code (OAC 1301:7-7, adopting the IFC) governs separation, egress, and smoke/CO alarms. Local press and the Akron-Cleveland Association of Realtors report that informal ADU practice in Akron permits units up to roughly 800 square feet with owner-occupancy expectations, but homeowners should verify current standards with Planning and Urban Development before designing.
