Summary
Hamilton's R-15, R-10, R-7 and R-5 Single-Family Districts each carry their own minimum yard setbacks under § 550-74E: front yards run from 40 feet in R-15 down to 20 feet in R-5, side yards from 15 feet down to 5 feet, and rear yards from 40 feet down to 25 feet. Larger accessory-building setbacks apply on top of those principal-building lines.

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. Building height in all four zones is capped at 35 feet and 2.5 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.
