Full Breakdown
Section 550-74E sets out the "area and yard requirements (detached dwellings)" table governing Hamilton's four core single-family districts. Minimum front yard depth runs 40 feet in R-15, 30 feet in R-10, 25 feet in R-7 and 20 feet in R-5. Minimum side yard width, each side, runs 15 feet in R-15, 10 feet in R-10 and R-7, and just 5 feet in R-5. Minimum rear yard depth runs 40 feet in R-15, 30 feet in R-10, 25 feet in R-7 and 25 feet in R-5.
Accessory buildings get their own, smaller setback numbers in the same table: 15 feet to the side line and 20 feet to the rear line in R-15, tightening to just 5 feet to either line in R-5, with a minimum 10-to-20-foot separation required between an accessory building and any other building on the lot. 5 stories under Subsection D, with accessory buildings limited to 15 feet. Hamilton's larger-lot districts carry even bigger numbers: the RRC and R-25 Zones require a 50-foot front yard and 50-foot rear yard under § 550-73B(7), and that table adds 40 feet to the minimum front or rear setback for any lot abutting a limited-access, arterial or major collector roadway.
Violations & Fines
Building or expanding a structure that doesn't meet its zone's front, side or rear yard minimum is a zoning violation the Township enforces under the general penalty at § 1-2: a fine up to $2,000, up to 90 days' imprisonment, or up to 90 days of community service, decided by the judge. A property owner who wants relief from these setbacks has to apply to the Zoning Board of Adjustment for a variance rather than simply building over the line.
