FENCE RULES – CLARK (COUNTY), NEVADA

OVERVIEW

Residential fences are permitted on private property within Clark County, subject to local regulations.

This page applies to properties in the unincorporated areas of Clark County; incorporated municipalities regulate fences under their own ordinances.

Clark County’s residential fence rules are not contained in a single stand-alone fence ordinance. They appear across Clark County Code Title 30: Unified Development Code, Clark County Code Chapter 22.02: Building Administrative Code of Clark County, the Clark County Fence/Block Wall Building Permit Guide, and department guidance from the Clark County Building Department, Current Planning, Public Works Development Review, and Code Enforcement – Public Response Office.

This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted materials do not state a specific limit or requirement, this page notes that the code does not specify one.

Compiled From Clark County Code Title 30: Unified Development Code, Clark County Code Chapter 22.02: Building Administrative Code of Clark County, Clark County Fence/Block Wall Building Permit Guide BPG-232, Clark County Building Department guidance, Code Enforcement – Public Response Office guidance, and Southern Nevada Building Officials Regional Standards as of May 2026.

GOVERNANCE

Clark County regulates fences in the unincorporated county through Title 30: Unified Development Code and Chapter 22.02: Building Administrative Code of Clark County.

Title 30 controls zoning, fence and wall height, location, setbacks, sight zones, materials, overlay districts, access gates, and maintenance standards. Chapter 22.02 and the Fence/Block Wall Building Permit Guide control fence permit exemptions, permit submittals, engineering triggers, and inspections.

Building-code administration is handled by the Clark County Building Department. Zoning review for fence height, location, and landscaping is handled through Current Planning. Drainage and right-of-way review is handled by Public Works Development Review. Complaint-based enforcement is handled by Code Enforcement – Public Response Office.

PERMIT AND APPROVAL REQUIREMENTS

• Building / Fence Permit: Clark County requires a fence permit unless an exemption applies. Type A fencing not over 6 feet high and not part of a pool barrier is exempt. Type B fencing, including retaining walls, not over 24 inches in height at any location is exempt. Repair of block walls 6 feet in height or less is exempt only when the repair is no greater than 20 linear feet. Fences over 6 feet require a building permit, and residential perimeter block walls over 24 inches require a building permit.

• Block Walls Over 6 Feet: Clark County guidance states that block walls over 6 feet require an administrative deviation from Comprehensive Planning.

• Fence Permit Review: Fence permit applications are submitted through the Clark County online permit system and are routed for review by Zoning Permit Sign-Off, Public Works Development Review, and Building Plans Examination.

• Zoning Sign-Off: Current Planning reviews fence permits for compliance with applicable zoning codes, including fence height, location, and landscaping requirements.

• Drainage and Right-of-Way Review: Public Works Development Review reviews fence permits for site drainage and right-of-way issues. Clark County states that no permits will be issued for fences or retaining walls that block natural drainage channels.

• Property-Line Walls: If a fence or block wall is located on the property line, the permit guide requires a notarized Property Line Authorization form.

• Engineering: Type A fencing over 8 feet, Type A fencing that requires a fence permit and has less than 50% open surface area, and extensions that increase the height of an existing Type A or Type B fence require engineering from a Nevada licensed design professional. Fencing 8 feet or less that is at least 50% open does not require engineering.

• Retaining Walls: Retaining Type B walls over 24 inches require a grading plan sealed by a registered design professional.

• Fire-Access Gates: A gate installed across a fire apparatus access road requires approval by the fire code official and a Fire Prevention Bureau installation permit.

• Historic Designation Overlay: In a Historic Designation Overlay, Design Review is required before significant alteration to any exterior structure visible from a street.

FENCE PLACEMENT RULES

• Required Setbacks: Title 30 allows fences and walls in required setbacks, subject to the applicable fence and wall height limits.

• Property-Line Placement: Fences and walls may be located on the property line where allowed by Title 30 height and location standards. For permit applications, walls located on the property line require a notarized Property Line Authorization form.

• Permit Site Plan: Permit drawings must show the proposed fence or block wall in relation to property lines, streets, other rights-of-way, existing buildings, landscaping, driveways, existing drainage courses, and sight zones.

• Drainage Channels: Clark County states that no permit will be issued for fences or retaining walls that block natural drainage channels.

• Rights-of-Way and Sidewalks: Fences, walls, and retaining walls must be maintained so they do not obstruct, block, pose a direct threat, or impede vehicular or pedestrian travel along a sidewalk or street.

• Access Gates: A single-family dwelling may restrict access with an access gate. If access to the dwelling is from an arterial or collector street, the access gate must be set back at least 20 feet from the property line.

• Utility Safety: Nevada law requires underground utility notification through Nevada 811 before excavation. For fence projects that involve digging, including fence post holes, notice must be provided before excavation begins.

FENCE HEIGHT AND VISIBILITY RULES

• Residential Front Setback: In residential districts, fences and walls are limited to 3 feet within the first 15 feet of the front setback. A fence may be increased up to 6 feet if decorative. In the RS80, RS40, RS20, and RS10 districts, a 6-foot high wall is permissible along collector and arterial streets.

• Residential Setbacks and Property Lines: In residential districts, fences and walls are limited to 6 feet in all setbacks or on the property line, except where the front-setback rule applies.

• Adjacent More Intense District: When adjacent to a more intense zoning district, fence and wall height along a common lot line may be permitted to the maximum height of the more intense district.

• Outside Setback Area: Fences or walls proposed outside of a setback area are limited to the primary structure height or accessory structure height, whichever is less.

• Decorative Features: Lamps, lighting, and decorative features on top of fence posts or columns may exceed the maximum allowable fence or wall height by no more than 1 foot.

• Height Measurement: Fence and wall height is measured from the high side of finished grade to the highest point of the fence, wall, or hedge. Within the front yard of single-family residences, height is measured from the top of the curb.

• Sight Zones: Sight zones must be established and maintained at intersections of public streets, private streets, alleys, and driveways. Except for listed exceptions, no structure, vegetation, or object may exceed 24 inches in height within a sight zone, measured from the top of the adjacent curb or future top of curb if no curb exists.

• Rural Neighborhood Preservation NPO: Within the Rural Neighborhood Preservation Neighborhood Protection Overlay, walls and non-decorative fences over 3 feet in the front setback are prohibited, except agricultural fencing in conjunction with a permissible agricultural and livestock use unless otherwise stated by Title 30.

• Red Rock Overlay: In the Red Rock Overlay, fences and walls, including retaining walls, must complement the architecture and exterior materials of the primary structure. No fence or wall may exceed 6 feet in height, except walls in conjunction with commercial development with frontage on a State Highway may be up to 8 feet. Retaining walls may not exceed 4 feet.

MATERIAL AND CONSTRUCTION LIMITS

• Allowed Materials: Clark County requires fences and walls to be made of high-quality, low-maintenance, durable materials. Listed materials include brick, stone, stucco, decorative concrete masonry unit, wrought iron, metal picket, pre-cast concrete that replicates brick, stone, stucco, or CMU, closed-style wood or stockade fencing, omega or welded wire, wood or concrete rail fencing, chain link with or without weather-resistant color, composite wood, durable vinyl, and durable aluminum.

• Nonurban Area Fencing: In the Nonurban Area, traditional farm fencing such as smooth wire mounted on posts, or alternative fencing used to confine domestic animals, is allowed when compatible with the rural character of the immediate area.

• Prohibited Materials: Clark County prohibits electrically charged fences in the Urban Area, except where battery-charged fencing is separately allowed. Barbed wire and concertina wire are prohibited except for security fencing allowed under Title 30. Fences constructed of chicken wire, corrugated metal, fabric, rope, fiberboard, plywood, or other non-traditional fencing materials are prohibited.

• Battery-Charged Fencing: Battery-charged fencing is allowed only in nonresidential zoning districts, in the Urban Area in the RS80 and RS40 districts, or in a residential zoning district in the Nonurban Area. The battery may not exceed 12 volts. The fence must be surrounded by a nonelectric perimeter fence or wall at least 5 feet high. Maximum height is 10 feet or 2 feet higher than the perimeter fence or wall, whichever is greater. Warning signs must be placed at intervals of no more than 40 feet.

• Red Rock Overlay Materials: In the Red Rock Overlay, chain link and coated chain link fences are prohibited. Wildlife-friendly fencing is required along conservation area boundaries. Traditional farm fencing or alternative domestic-animal fencing may be used when compatible with the character of the immediate area.

• Regional Standard Designs: Clark County allows Southern Nevada Building Officials Regional Standard designs to be used in place of structural drawings and calculations within the height limits of the applicable standard, but a copy of the applicable regional standard must still be submitted with the permit package.

PRIVATE RESTRICTIONS

Private covenants, deed restrictions, HOA rules, private development standards, and planned community documents operate independently from Clark County fence rules and may be more restrictive.

Clark County states that Title 30 regulations are in addition to private easements, covenants, deed restrictions, and other private agreements, and that the County is not responsible for monitoring or enforcing private agreements or restrictions.

REVIEW AND ENFORCEMENT CONTEXT

Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:

• Permit-Required Fences: Type A fences over 6 feet, Type B fences or block walls over 24 inches, and non-exempt block-wall repairs may be reviewed through the Clark County fence or building permit process.

• Zoning Review: Fence height, location, front-setback limits, landscaping requirements, overlay standards, and administrative deviations for block walls over 6 feet may be reviewed through Current Planning.

• Drainage and Right-of-Way Review: Fences and retaining walls that affect drainage channels, rights-of-way, or required site drainage may be reviewed by Public Works Development Review.

• Sight and Travel Obstructions: Fences, walls, vegetation, or objects in sight zones are subject to the 24-inch sight-zone standard. Fences and walls must not obstruct travel along sidewalks or streets or block the view of traffic signals, signs, directional devices, or sight zones.

• Material Restrictions: Prohibited materials, electrically charged fencing, battery-charged fencing, chain-link restrictions in the Red Rock Overlay, and barbed or concertina wire limitations may be reviewed under Title 30.

• Required Inspections: Permitted fence and block-wall work may require inspections, including footing inspection before concrete foundations are poured and masonry pre-grout inspection before masonry fences or retaining walls are grouted.

• Complaint-Based Enforcement: Code Enforcement – Public Response Office handles complaints involving zoning violations, unpermitted construction, building violations, and related Clark County Code issues.
