Full Breakdown

Building height in Ohio is a local zoning matter. Cities and villages set maximum heights and story counts by zoning district. In unincorporated Montgomery County, township boards may regulate the 'height, bulk, number of stories, and size of buildings and other structures' under Ohio Revised Code 519.02, applied through a comprehensive plan. There is no uniform county height cap. Residential districts often limit homes to about 35 feet or 2.5 stories, but the exact figure depends on your zoning district, so confirm with the municipality or township that governs your parcel before designing or adding a story.

Violations & Fines

Exceeding the local height limit without a variance can bring a zoning-violation notice, fines set locally, and an order to modify the structure, per your city or township code.
