Full Breakdown
Ohio setbacks are local: cities zone inside their limits and townships zone the unincorporated area under ORC Ch. 519 (or use the county Rural Zoning Resolution under ORC Ch. 303). For standalone lots under the county resolution (8.0605), single-family front-yard depth is 35 ft in R-1, 30 ft in R-1A/R-2, and 25 ft in R-3/R-4; minimum one-side yards run 8–15 ft and rear yards 30–45 ft. West Chester and other self-zoning townships, plus cities like Hamilton and Middletown, publish their own setback tables. Verify your zoning district and jurisdiction before building.
Violations & Fines
Encroaching on a required yard is a zoning violation: misdemeanor under 25.51, up to $500 per day, each a separate offense; a variance may be needed.
