Las Vegas, NV Fence Regulations: Permit Requirements (2026)

Clark County Code Title 30 (Unified Development Code) administered by Clark County Department of Building and Fire Prevention requires a permit for any fence, wall, or retaining wall exceeding 6 feet in height above finished grade. Masonry and concrete block walls (extremely common in desert Las Vegas Valley construction) typically require a permit regardless of height because they involve footings, rebar, and structural engineering. Wood, chain link, and wrought iron fences under 6 feet generally do not require a building permit but still must comply with Title 30.56 setback and height standards. Permit applications go through the Department of Building and Fire Prevention and require site plan, property survey showing setbacks, elevation drawings, and for masonry over 4 feet a structural engineering detail. Fees are calculated on valuation. Corner lots have reduced allowable heights in front yard vision triangles (typically 3.5 feet). Walls on top of retaining structures count toward combined height. HOAs across Summerlin, Spring Valley, Enterprise, and Mountains Edge often impose stricter architectural review in addition to the county permit.
