Salt Lake County, UT Building Setbacks & Zoning: Setback Rules (2026)

Corner lots in unincorporated Salt Lake County residential zones are subject to additional setback and sight-distance requirements under Title 19. The primary street frontage is determined by the address orientation and receives the full front setback for the zone (typically 20 to 30 feet). The secondary street frontage receives a reduced front setback, commonly 15 to 20 feet, which is greater than a standard side yard setback. This secondary-street setback applies to both the primary dwelling and any street-facing accessory structures such as detached garages. A clear sight-distance triangle is established at the intersection of the two street rights-of-way. The triangle is typically defined by a 25-foot or 30-foot leg along each curb line, and within the triangle no solid fence, wall, hedge, landscaping mass, or structure over 3 feet high is permitted to obstruct driver visibility between 3 and 8 feet above grade. Open ornamental fencing above 3 feet may be allowed if sight-through. Trees within the triangle must be limbed up to maintain at least 8 feet of clearance above grade. Corner-lot fences in the side yard along the secondary street can be up to 6 feet tall outside the sight triangle, consistent with standard fence heights. Driveways on corner lots are typically limited to one street frontage, often the lower-traffic street.
