Summary
Unincorporated Utah County's RR-5 Rural Residential Zone requires a 30-foot front yard setback and a 15-foot side and rear setback for every building and structure. Detached accessory structures and accessory dwelling units of 1,500 square feet or less can sit as close as 10 feet to the property line. The same 30-foot and 15-foot minimums govern the RA-5 Agricultural Zone next door.
Location Requirements: The minimum location requirements within the RR-5 zone shall be as follows: Front Setback: All Buildings and Structures, other than certain public facilities, landscaping features and Fences which meet the standards of UCLUO 4, UCLUO 6, and UCLUO 8, shall have a front Setback of at least thirty (30) feet, unless an alternate Setback is required or allowed by UCLUO 4, UCLUO 6, and UCLUO 8. Side and Rear Setback: All Buildings and Structures, other than landscaping features and Fences which meet the standards of UCLUO 4, UCLUO 6, and UCLUO 8 shall have a side and rear Setback of at least fifteen (15) feet, unless an alternate Setback is required or allowed by UCLUO 4, UCLUO 6, and UCLUO 8, or as provided for below: A Residential Accessory Structure, including a Detached Accessory Dwelling Unit, with a Floor Area of 1,500 square feet or less may have a minimum Setback of ten (10) feet.
Full Breakdown
Utah County's land use ordinance (UCLUO) sets yard setbacks by zone under the Location Requirements provisions of each zoning chapter. 12), the minimum front setback is 30 feet for every building and structure, other than fences and certain public facilities that meet the standards of UCLUO 4, 6 and 8. Side and rear setbacks default to 15 feet, but a detached residential accessory structure, including a detached accessory dwelling unit, drops to a 10-foot minimum if its floor area is 1,500 square feet or less.
A further exception lets a recorded large-scale development plat set the controlling setback line instead, provided the development's water system supplies fire hydrants meeting current Utah County fire-flow standards. 08, so most large-lot unincorporated parcels share this baseline. These setbacks stack with, not replace, height and Airport Overlay Zone restrictions: the code notes those provisions can force a larger setback than the zone's base standard. The Utah County Community Development Department's Zoning Administrator checks proposed structure placement against recorded lot lines during building permit and plot-plan review.
Any alternate setback allowed elsewhere in UCLUO 4, 6 or 8, for fences, corner lots, or specific accessory uses, supersedes the base 30/15-foot figures for that particular structure type.
Violations & Fines
Utah County Code § 1.04.010 sets the default penalty for code violations not otherwise classified: a fine up to $1,000, up to six months in the county jail, or both, with each day a setback violation continues charged as a separate offense. The Zoning Administrator enforces setback compliance through building permit and plot-plan review and can withhold approval, or require removal or relocation of a noncompliant structure, before construction may proceed.
