How Chico Handles Fence Regulations: A Practical Guide
Chico maintains 133 local ordinances across all categories, and 4 of those deal specifically with fence regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Chico falls on the strict-to-permissive spectrum compared to other cities.
Retaining Walls
Chico exempts retaining walls up to 4 feet from setback rules, allows walls 4 to 6 feet in a setback only when the exposed face points inward, and treats anything taller as a main structure needing full zoning compliance.
Key details: Up to 4 ft: Exempt from setbacks. 4-6 ft in setback: Only if face points inward. Over 6 ft: Treated as main structure. Governing section: CMC § 19.60.090(F)(4).
An unpermitted retaining wall that violates the height or setback thresholds in § 19.60.090 can draw a stop-work order and require modification or removal to bring it into compliance.
Material Restrictions
Chico prohibits barbed wire, electrified fencing, and razor wire on fences and walls in every zoning district; electrified fencing is allowed only in commercial or industrial zones with a use permit and Civil Code safeguards.
Key details: Barbed wire: Banned in all zoning districts. Electrified fence: Commercial/industrial use permit only. Razor wire: Prohibited residentially. State overlay: Civil Code § 835 safeguards apply.
Installing barbed wire, electrified fence, or razor wire without a qualifying commercial/industrial use permit is a zoning violation; the Director can require removal or refer the property for code enforcement.
Compared to other cities, Chico takes a harder line on material restrictions. The enforcement and penalty structure reflects that.
Fence Permit Requirements
Chico exempts fences 6 feet or under from a building permit, but zoning still caps residential fences at 3 feet in front yards and 7 feet in rear/side yards, with taller heights requiring an administrative or use permit.
Key details: Front yard limit: 3 ft by right. Rear/side yard limit: 7 ft by right. Building permit exempt: fences 6 ft or under. Taller fence needs: admin or use permit.
Building a fence taller than the zoning height limit without the required administrative or use permit is a code violation enforceable as an infraction under the general penalty provision, § 1.04.120; the City can require removal or after-the-fact permitting and approval.
Height Limits
Where multi-family, commercial, or manufacturing property in Chico adjoins a residential zone, the code requires a 6-foot sight-obscuring wood fence or masonry wall along the shared property line for privacy screening.
Key details: Governing section: § 19.60.060(H)(1). Standard height: 6 feet, wood or masonry. With lattice top: Up to 7 feet allowed. Triggers when: Multi-family/commercial adjoins residential.
Building without the required screening wall, or below the mandated height, is an infraction under § 1.04.120, enforced by the Community Development Director as a zoning code violation with each day counted as a separate offense.
The Bottom Line
Chico's fence regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Chico is broadly strict or permissive.
All of the above reflects Chico'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.
