St. George, UT Building Setbacks & Zoning: Setback Rules (2026)

City code Section 10-7B-3 sets minimum yard setbacks for each single-family zone. R-1-6 through R-1-8 require a 20-foot front and street-side setback, a 10-foot rear setback, and a 6- or 8-foot side setback depending on whether a public utility easement exists. Larger-lot zones (R-1-10 through R-1-40) keep the 20-foot front and 10-foot rear setback but raise the side setback to 8 feet. The R-1 zone (density tied to the General Plan) requires a 15-foot front setback, with a 20-foot setback where a garage faces the street; an open porch may encroach 5 feet into that setback.
