How Chico Handles Fence Regulations: A Practical Guide

Chico maintains 96 local ordinances across all categories, and 6 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.

Approved Materials

CMC §19.60.060(F) prohibits barbed wire, razor wire, and electrified fencing in all zoning districts unless approved by use permit in a commercial or industrial zone. Approved commercial electrified fences must sit behind a 6-ft perimeter fence with warning signs.

Key details: Barbed wire: Prohibited in residential; use-permit in C/I only. Razor wire: Prohibited in all zones (CMC 19.60.060(F)). Electrified fence: Use permit + 6-ft perimeter + warning signs. Code section: CMC §19.60.060(F).

Installing prohibited fence types (barbed/razor/electric) without authorization is a CMC violation. Code Enforcement may order removal, and continued violations carry administrative citations and abatement costs under CMC Title 1.

This is one of the stricter rules in Chico's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Neighbor Fence Rules

Chico defers to California Civil Code §841, the Good Neighbor Fence Act. Adjoining owners are presumed to share equally in the cost of a boundary fence's construction, maintenance, and replacement. A landowner planning fence work must give 30 days' written notice to neighbors.

Key details: Governing law: Cal. Civil Code §841 (Good Neighbor Fence Act). Default cost split: 50/50 presumption. Notice required: 30 days written, prior to construction. Local rule: No Chico ordinance — state law applies.

There is no Chico Code Enforcement action for cost-share disputes — these are civil matters under Civ. Code §841. Failure to provide the 30-day notice can be used by the neighbor as a defense against contribution claims.

Height Limits

Under Chico Municipal Code (CMC) §19.60.060, front-yard fences on standard parcels are capped at 3 feet, while side and rear yard fences may rise to 7 feet. Greater heights require an administrative use permit or use permit through the Planning Division.

Key details: Front yard (by-right): 3 ft max (CMC 19.60.060). Side/rear yard: 7 ft (8 ft w/ admin permit). Permit path for taller front fence: Admin use permit (4 ft) or use permit (6 ft). Code section: CMC §19.60.060 + §19.60.070.

Fences exceeding the by-right height limit without an approved use permit are zoning violations enforced by Chico Code Enforcement. Typical remedy is a notice ordering the fence be lowered or permit obtained; civil penalties accrue under CMC Title 1 for continued non-compliance.

Retaining Walls

Per CMC §16.10.020 and the City of Chico Building FAQ, retaining walls 4 feet or less in height (measured from bottom of footing to top of wall) that do not support a surcharge are exempt from building permits. Walls exceeding 4 feet, supporting a structure/fence, or impounding hazardous liquids require a building permit with engineered plans.

Key details: Permit-exempt height: ≤ 4 ft, no surcharge. Permit required: > 4 ft OR any height with surcharge. Engineering required: Yes, for permitted walls. Code section: CMC §16.10.020 + CBC.

Building without a required permit can result in stop-work orders, double permit fees, and forced removal or engineering retrofit. Code Enforcement may post the structure unsafe under the California Building Code.

Pool Barriers

Chico enforces the California Swimming Pool Safety Act (HSC §115920–115929, amended by SB 442). New or remodeled pools/spas at single-family homes must install at least two of seven drowning-prevention safety features, including a 60-inch enclosure meeting Cal. Building Code Appendix AX.

Key details: Minimum features required: 2 of 7 (SB 442, eff. 1/1/2018). Enclosure height: 60 inches minimum. Max gap: 4-inch sphere cannot pass. Governing law: Cal. HSC §115920–115929.

Failure to install required safety features results in failed building inspection and inability to obtain a Certificate of Occupancy or final approval. Property owners face civil liability under HSC §115929 and personal injury exposure for non-compliant pools.

This is not one of those rules that cities tend to ignore. Chico actively enforces its pool barriers requirements.

Permit Requirements

A building/zoning permit is generally required in Chico for fences over 6 feet or masonry/retaining walls; pool barrier fences must meet the California Building Code. Standard residential fences at the height limit may be permit-exempt.

Key details: Permit: Over 6 ft / masonry. Pool Fences: CBC barrier required. Standard Fences: Often permit-exempt. Authority: Building / planning.

The Bottom Line

Chico is tougher than many cities when it comes to fence regulations. Out of the 6 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Chico, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
