Fence Regulations in Tempe, AZ: What Residents Actually Need to Know

If you live in Tempe or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Tempe has 6 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Neighbor Fence Rules

Tempe does not require neighbor consent to build a fence on your property, but fences must be within your property lines. Shared boundary fences are governed by Arizona state law, which generally splits costs equally between benefiting property owners.

Key details: Neighbor Consent: Not required if on your property. State Law: ARS 33-1231 — shared boundary fences. Cost Sharing: Equal for partition fences benefiting both. Property Lines: Survey recommended for disputes.

Fences built over property lines may result in civil disputes. The city does not mediate private property line issues but enforces zoning compliance. Fences that block sight triangles on corner lots are subject to enforcement.

Tempe is more permissive than most cities when it comes to neighbor fence rules. That said, there are still limits.

Retaining Walls

Tempe requires building permits for retaining walls over 4 feet in height. Walls exceeding 4 feet must be designed by a licensed engineer. Combined height of retaining wall and fence on top counts toward height limits. Retaining walls must not redirect drainage onto neighboring properties. The building code (Chapter 8) and Zoning and Development Code govern retaining wall construction.

Key details: Permit Threshold: Over 4 ft requires building permit. Engineering: Required for walls over 4 ft. Combined Height: Wall + fence counts toward zoning limits. Drainage: Must not redirect water to neighbors. Soils: Expansive clays in some Tempe areas.

Retaining walls over 4 feet built without permits or engineering may face stop-work orders, fines, and mandatory remediation.

Height Limits

Tempe's zoning code limits residential fence heights to 6 feet in side and rear yards and 3 feet in front yards. Corner lots may have additional visibility triangle requirements to ensure driver sight lines at intersections.

Key details: Front Yard Max: 3 feet. Side/Rear Yard Max: 6 feet. Corner Lots: Sight triangle restrictions apply. Code: Tempe Zoning and Development Code.

Fences exceeding height limits receive code enforcement notices requiring modification within a set period. Non-compliance may result in fines and mandatory removal.

Permit Requirements

Tempe generally does not require a building permit for standard residential fences up to 6 feet in height. Fences exceeding 6 feet, masonry walls, and fences with electrical components require a permit.

Key details: Permit Exempt: Standard fences up to 6 feet. Permit Required: Masonry walls, over 6 feet, electrical. Pool Fences: Must meet safety barrier requirements. Setbacks: Must comply regardless of permit.

Building a fence requiring a permit without one may result in a stop-work order and requirement to obtain the permit retroactively. Non-compliant fences may need to be modified or removed.

If you are coming from a city with tighter rules, you will find Tempe gives residents more flexibility on permit requirements.

Material Restrictions

Tempe's Zoning and Development Code regulates fence materials in residential zones. Common permitted materials include block, stucco, wrought iron, wood, vinyl, and chain link. Barbed wire, razor wire, and electric fences are prohibited in residential districts. Chain link may be restricted along street frontages. Many Tempe neighborhoods have HOA-imposed material requirements.

Key details: Permitted Materials: Block, stucco, wrought iron, wood, vinyl, chain link. Prohibited in Residential: Barbed wire, razor wire, electric fences. Chain Link: May be restricted along street frontages. HOA Rules: Many neighborhoods have additional material requirements. Maintenance: Deteriorated fences must be repaired or replaced.

Fences built with prohibited materials may result in code compliance citations and orders to replace with approved materials.

Pool Barriers

Tempe enforces strict pool barrier requirements aligned with Arizona state law (ARS 36-1681). All pools, hot tubs, and spas with water over 18 inches deep must be enclosed by a barrier at least 5 feet high with self-closing, self-latching gates. Gate latches must be at least 54 inches above grade. The city inspects pool barriers during construction, remodels, and property sales.

Key details: State Law: ARS 36-1681. Barrier Height: 5 feet (60 inches) minimum. Gate Latch: 54 inches above grade, self-closing/self-latching. Opening Size: No gap allowing 4-inch sphere. House Doors: Self-closing device and alarm if opening to pool.

Non-compliant pool barriers are serious safety violations with fines, mandatory correction orders, and potential liability under ARS 36-1681.

Compared to other cities, Tempe takes a harder line on pool barriers. The enforcement and penalty structure reflects that.

The Bottom Line

Compared to many U.S. cities, Tempe gives residents more room on fence regulations. 2 of the 6 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Tempe'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.
