West Valley City, UT Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 7-6-210, titled Specific Requirements, RM Zone, sets the RM district's full dimensional package, and subsection (7) closes it with the coverage cap: no building or group of buildings, including accessory buildings, may cover more than 60 percent of the lot area. That figure sits alongside the zone's other numbers: the minimum lot area is 8,000 square feet for each single unit dwelling and 4,000 square feet per dwelling unit for twin homes, or 20,000 square feet for any other use (1); the front yard setback for residential uses is 25 feet, reducible only through a development agreement between the owner and the City, while nonresidential front and rear setbacks are 20 feet (5); and where the RM lot sits next to a residential use of two stories or less, building height is capped at 25 feet at the minimum side and rear setback, with every additional foot of height requiring an additional foot of setback, up to a total maximum height of 75 feet (6).

No other zone in the West Valley City Municipal Code carries a comparable percentage-of-lot coverage limit; the Agricultural and Residential Standards Table at Section 7-6-202 that governs the single-family zones lists lot size, width, setbacks, and height, but no coverage percentage, making the RM standard a distinct, standalone control on building bulk. The section was last amended by Ordinance No. 18-13 in 2018 and renumbered from its former designation by Ordinance No. 18-42 that same year.
