Fence Regulations in Santa Rosa, CA: What Residents Actually Need to Know

If you live in Santa Rosa or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Santa Rosa has 5 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Material Restrictions

Santa Rosa City Code Section 20-30.060.G prohibits barbed wire fencing in residential, commercial, and other non-agricultural areas, allowing it only in agricultural, open space, or industrial areas. Barbed wire abutting residential uses requires a Minor Conditional Use Permit. In Wildland Urban Interface (WUI) areas, fences attached to dwellings or accessory structures must use non-combustible materials for the first 5 feet (or 3 feet if sprinklered).

Key details: Barbed wire - residential abutments: Minor CUP required. Barbed wire - allowed without CUP: Agricultural, open space, industrial only. WUI non-combustible zone: First 5 ft of fence touching dwelling (3 ft if sprinklered). Wood post material: Redwood or pressure-treated Douglas fir #2+. Code sections: SRCC 20-30.060(G), 18-22 R337.10.3.4.

Installing barbed wire in residential or commercial zones without a Minor Conditional Use Permit, or installing a combustible fence in a designated WUI area, is a Zoning Code and Building Code violation. Code Enforcement may require removal of non-conforming materials and may issue administrative citations or refer the matter for misdemeanor prosecution under City Code Chapter 1-28.

Approved Materials

Santa Rosa zoning permits standard residential fence materials (wood, vinyl, masonry, ornamental metal, chain link). Barbed wire, razor wire and electrified fencing are generally prohibited in residential zones.

Key details: Allowed: Wood, vinyl, masonry, metal. Restricted: Barbed/razor/electric. Regulated Under: Zoning. Zone-Dependent: Yes.

Contact your local code enforcement office for specific penalty information.

Santa Rosa is more permissive than most cities when it comes to approved materials. That said, there are still limits.

Height Limits

Santa Rosa Zoning Code Section 20-30.060 caps residential fences at 36 inches within the front-yard or exterior-side setback, and 6 feet within an interior-side or rear-yard setback. A 6-foot fence with 2 feet of lattice (8 feet total) is allowed by right outside the front/street-side setback, but any fence over 7 feet requires a Building Permit.

Key details: Front-yard setback: 36 inches max. Exterior side (street-side) setback: 36 inches max. Interior side / rear-yard setback: 6 feet (8 ft with lattice). Outside required setback: 6 feet (8 ft with lattice). Building Permit threshold: Any fence over 7 feet.

Building a fence taller than Table 3-1 limits without a Minor Director Conditional Use Permit (for heights in residential setbacks) or without a Building Permit (for any fence over 7 feet) is a Zoning Code violation. Santa Rosa Code Enforcement may issue a notice of violation, require removal or height reduction, and pursue administrative citations under City Code Chapter 1-28. Fences within a vision triangle that obstruct visibility must be removed regardless of permit status.

Permit Requirements

Santa Rosa requires a Building Permit for any fence exceeding 7 feet in height. A 6-foot fence with 2 feet of lattice (8 feet total) is allowed by right without a zoning permit in interior side, rear, or out-of-setback locations, but the 7-foot Building Permit threshold still applies. Heights beyond the Table 3-1 limits also require a Minor Director Conditional Use Permit (not available in a vision triangle).

Key details: Building Permit trigger: Any fence over 7 feet. Zoning permit (no Building Permit): Up to 7 ft (or 8 ft with lattice) in allowed locations. CUP for extra height: Minor Director Conditional Use Permit, Section 20-30.060.D. Temporary construction fences: Exempt (Section 20-30.060.F) if Building Code compliant. Permit portal: Permit Santa Rosa (online).

Building a fence over 7 feet without a Building Permit, or exceeding Table 3-1 heights without a Minor Director CUP, is enforceable by Code Enforcement via stop-work order, administrative citation, and required removal. Submitting Building Permit applications for fences that interfere with Fire Department access or create traffic hazards will be denied under Section 20-30.060(E).

Neighbor Fence Rules

Santa Rosa follows California Civil Code for boundary fences. Costs for boundary fences are shared equally between neighbors. Disputes may be resolved through mediation.

Key details: Cost Sharing: Equal per CA Civil Code §841. Consent: Not needed if on your property. Boundary Fences: Shared responsibility. Disputes: Mediation available through county.

Fence disputes are civil matters between neighbors. The city does not mediate private property disputes but enforces code compliance.

If you are coming from a city with tighter rules, you will find Santa Rosa gives residents more flexibility on neighbor fence rules.

The Bottom Line

Compared to many U.S. cities, Santa Rosa gives residents more room on fence regulations. 2 of the 5 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.

Keep in mind that Santa Rosa can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
