How Salt Lake City Handles Building Setbacks & Zoning: A Practical Guide
Salt Lake City maintains 165 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Salt Lake City falls on the strict-to-permissive spectrum compared to other cities.
Setback Rules
In the R-1/7,000 single-family zone, Salt Lake City requires a 25-foot rear yard, 6-foot interior side yards (10 feet on one side of interior lots), and a front yard matched to the block face.
Key details: Rear yard (R-1/7,000): 25 feet. Interior side yard: 6 ft / 6 ft+10 ft. Front yard default: 20 feet. Front yard rule: Matches block-face average.
Building within the required yard without an approved variance, special exception, or accessory-structure exemption is a zoning violation subject to a stop-work order and correction through the Salt Lake City Building Services/Planning Division.
Lot Coverage Limits
In the R-1/7,000 single-family zone, Salt Lake City limits building coverage, the footprint of every principal and accessory building, to 40% of the lot area, leaving the rest as yard, driveway, or open space.
Key details: R-1/7,000 max coverage: 40% of lot area. FR-1/43,560 max coverage: 25% of lot area. Counts toward cap: principal + accessory buildings. Enforcement: Zoning Administrator, civil fines. Fine (residential): $50 per day per violation.
Zoning Administrator enforcement; unpermitted overage triggers a stop-work/correction order, then civil fines of $50 per day per violation on residential property until corrected (§ 21A.20.040.A).
Structure Height Limits
Single-family homes in Salt Lake City's R-1/12,000 district top out at 28 feet to the ridge on a pitched roof, or 20 feet on a flat roof, measured from established grade.
Key details: Pitched roof max: 28 feet to ridge. Flat roof max: 20 feet. Interior side wall max: 20 feet at setback line. District example: R-1/12,000 Single-Family. Historic overlay: Landmark commission can add height.
Building without a permit that reflects the height limit risks a stop-work order and required modification from the Salt Lake City building permits division; contested height disputes go to the board of adjustment for a variance.
The Bottom Line
Salt Lake City's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Salt Lake City is broadly strict or permissive.
All of the above reflects Salt Lake City's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
