Full Breakdown
The Allen County Zoning Ordinance caps building height by district. In the R1 Single Family Residential district, the maximum height for a primary building is 40 feet and for an accessory building is 25 feet. Exceptions and additional restrictions apply under the Development Standards Waivers section (A.C.C. 3-4-5-3), the Sign standards, the Residential Impact Mitigation section (A.C.C. 3-4-4-15), and the Airport Overlay Districts (A.C.C. 3-4-11). Lighting poles serving a residential use are limited to 25 feet. Other districts (agricultural, higher-density residential, commercial) have their own height maximums, so confirm the standard for your parcel's zoning with the Department of Planning Services.
