The county resolution controls buildable area through minimum lot size and density rather than a fixed coverage percentage: R-1 needs 20,000 sq ft, down to 6,500 sq ft in R-4. Cities and self-zoning townships set their own coverage rules.
Butler County's Rural Zoning Resolution does not impose a single lot-coverage percentage for houses; instead it limits building intensity through minimum lot area, minimum frontage, required yards, and density. Under Section 8.0605, standalone single-family lots require a minimum of 20,000 sq ft in R-1, 15,000 in R-1A, 9,000 in R-2, 7,000 in R-3, and 6,500 in R-4, each with prescribed frontage and yards that together cap footprint. Maximum gross density ranges by district (e.g. 1.9 units/acre in R-1). Cities and self-zoning townships set their own coverage and impervious-surface rules.
Over-building a lot beyond permitted area/yards is a zoning violation: misdemeanor under 25.51, up to $500 per day; a variance may be required.
