Rohnert Park FAQ
Can I install barbed wire on top of my fence in unincorporated Sonoma County?
Not in residential or K zones. Permit Sonoma's adopted fence standards (PJR-133) prohibit barbed wire and razor wire in those zones; you may install them in agricultural, commercial, or industrial zones.
Is chain-link fencing allowed?
Yes. Woven metal fencing, including chain-link and hog wire, is on the list of permitted materials for residential and K zones.
Can I leave my concrete-block fence unfinished?
No in residential and K zones. Exposed (uncovered) concrete masonry units are prohibited; CMU walls must be covered with stucco, plaster, or veneer.
Santa Rosa FAQ
Can I top my Santa Rosa residential fence with barbed wire?
No, not by right. Section 20-30.060.G allows barbed wire only in agricultural, open space, or industrial areas. If your fence merely abuts a residential use, a Minor Conditional Use Permit is required.
Do I have to use special materials for a fence touching my house in a fire-hazard area?
Yes. If your home is in a designated Wildland Urban Interface (WUI) area, the portion of any new fence attached to the dwelling or an accessory structure, plus the first 5 feet of that fence, must be built with non-combustible materials. The requirement drops to 3 feet if the building has fire sprinklers.
Are there other prohibited fence materials in Santa Rosa?
The Zoning Code itself only specifically restricts barbed wire. However, fences must meet the California Building/Residential Code structural standards, and the Building Official may refuse a permit for any fence that creates a fire-access or traffic-safety hazard under Section 20-30.060(E).
