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

1540, Minimum Lot Standards, governs every lot in the R-1 Residential Single-Family zone: a minimum 9,000-square-foot lot area, 75-foot lot width, 25-foot front yard, 8 feet on each side yard, a 25-foot rear yard, and a building height cap of two stories or 30 feet. 140, Supplementary Setback And Yard Requirements, adds the rules that make those numbers work in practice. Every part of a required yard must stay open from the ground to the sky, with only narrow exceptions: chimneys and bay windows up to six feet wide can project 24 inches into a yard, unsupported cornices, eaves, gutters and unroofed porches and steps can project further, and light-control screens attached to the main wall can extend three feet into a yard.

Accessory buildings get their own break: side and rear yards for a shed, garage or other accessory structure can shrink to three feet, but only if the structure sits at least six feet behind the principal building, sixteen feet from a neighbor's principal building, and eight feet from any adjacent vacant lot. A required yard on one lot can never be borrowed to satisfy another lot's setback, and no owner may sell or lease away the space needed to meet the county's width, yard, or parking minimums.

Corner lots carry an added visibility rule: nothing in the sight triangle, from two and a half feet to ten feet above the street's centerline grade, may block the view within 40 feet of the intersection. Davis County Community Development administers these standards through the building permit and site plan review process.
