Montgomery County has no countywide lot-coverage limit. The maximum percentage of a lot you can build on is set by your city or village zoning code, or by township zoning under Ohio Revised Code 519.02, which regulates the percentage of lot area that may be occupied.
Lot coverage (the share of a parcel covered by buildings and, sometimes, impervious surface) is a local zoning standard in Ohio. Cities and villages set coverage caps by district. In unincorporated Montgomery County, township boards may regulate 'the percentages of lot areas that may be occupied' and yard and open-space sizes under Ohio Revised Code 519.02. There is no single county figure. Residential districts commonly cap building coverage around 25-40 percent, but the exact limit depends on your zoning district, so confirm with your municipality or township before adding a structure or expanding.
Exceeding the permitted lot coverage without a variance can bring a zoning-violation notice, local fines, and an order to remove the excess structure, per your city or township code.
