How Salt Lake City Handles Fence Regulations: A Practical Guide
Salt Lake City maintains 165 local ordinances across all categories, and 4 of those deal specifically with fence regulations. 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.
Height Limits
Salt Lake City caps front-yard fences at 4 feet and side/rear fences at 6 feet in residential zones, and requires a building permit for nearly every fence under Zoning Code Section 21A.40.120.
Key details: Front-yard fence height: 4 feet max. Side/rear fence height: 6 feet max. Building permit: Required for nearly all fences. Placement: Entirely within property lines. Overlay districts: Foothill, Historic add extra rules.
Unpermitted or over-height fences are zoning violations; the city can seek a court order to enter and abate them, then bill the owner and file a property tax lien for costs (Section 21A.20.090/.100). Uncodified violations default to a class B misdemeanor up to $1,000 (Section 1.12.050).
Retaining Walls
In Salt Lake City's Foothills Protection and FR-1/FR-2/FR-3 districts, retaining walls cap at 4 feet above established grade, and any wall taller than that needs a state-licensed structural engineer's stamp tied to a geotechnical report.
Key details: Max height (no engineer): 4 feet above established grade. Trigger for wall requirement: Cuts/fills over 2 feet. Terrace spacing (4-ft walls): 3 feet horizontal minimum. Terrace spacing (6-ft walls): 5 feet horizontal minimum. Engineer required: Any wall over 4 feet tall.
Building or stacking a retaining wall over 4 feet without an engineer's stamp, or terracing walls closer than the required horizontal separation, is a zoning violation the Zoning Administrator can require to be redesigned or removed before further grading or building permits are issued.
Material Restrictions
Salt Lake City zoning bans barbed wire, razor wire, and electric security fences on residential property, limiting them to agricultural, commercial, and manufacturing zones.
Key details: Barbed wire in residential zones: Not a permitted use. Razor wire allowed zones: M-1, M-2, EI only. Electric fence near residential: Prohibited if abutting. Barbed wire max strands: 3, min 7 ft high. Electric fence perimeter wall: 6 ft min, nonelectrical.
Zoning enforcement issues a notice of violation for a nonconforming fence; the property owner must remove or bring the barbed wire, razor wire, or electric fencing into compliance, with fines for continued noncompliance.
This is one of the stricter rules in Salt Lake City's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Fence Permit Requirements
Salt Lake City requires a building permit before building almost any fence, with a fee tied to construction cost or valuation.
Key details: Permit trigger: Nearly all fences, any height. Fee basis: Construction cost/valuation. Extra plan detail: Required over 6 ft or masonry. Overlay districts: Foothills, Historic, FR-1–FR-3 add rules.
Building without the required permit exposes the fence to a stop-work order and removal or retroactive permitting through the Building Services Division, plus permit fees assessed after the fact.
The Bottom Line
Salt Lake City's fence regulations 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.
