How Fullerton Handles Fence Regulations: A Practical Guide
Fullerton maintains 149 local ordinances across all categories, and 5 of those deal specifically with fence regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Fullerton falls on the strict-to-permissive spectrum compared to other cities.
Retaining Walls
A Fullerton retaining wall over three feet in a front yard, or over four feet in a rear or side yard, needs Director of Development Services approval before it can go in. Fullerton Municipal Code § 15.17.050(G)(2) sets the review trigger and a minor site plan requirement for walls that enlarge buildable area.
Key details: Front yard trigger: Over 3 feet needs Director approval. Rear/side yard trigger: Over 4 feet needs Director approval. Buildable-area walls: Require minor site plan, Chapter 15.47. Landscaping exemption: Decorative terrace walls are exempt. Reviewing office: Director of Development Services.
Constructing a retaining wall above three feet in a front yard or four feet in a rear or side yard without Director of Development Services approval, or without the required minor site plan when the wall enlarges buildable area, violates § 15.17.050(G)(2). It is enforced under § 1.08.010 as an infraction ($100 first offense, $200 second, $500 thereafter within a year) or as a misdemeanor with fines up to $1,000 and up to six months in County Jail, and the city can require the wall be modified or removed.
Material Restrictions
Fullerton Municipal Code 15.17.050 does not enumerate prohibited fence materials, but the Director of Development Services reviews construction materials for compatibility and vision clearance whenever a non-view-obscuring exception is requested. Standard residential fences are typically wood, vinyl, masonry, or wrought-iron.
Key details: City prohibited-material list: None enumerated in FMC 15.17.050. Director review factors: Materials, compatibility, vision clearance. Typical accepted materials: Wood, vinyl, masonry, wrought-iron. Boundary cost-sharing: Cal. Civ. Code 841 (Good Neighbor Fence Law).
Fences using materials the Director deems incompatible (e.g., razor wire, barbed wire, or scrap materials in a residential zone) may be denied a height exception or cited as a public-nuisance Zoning Code violation. Code Enforcement may require removal or replacement. Disputes over boundary-fence materials and cost-sharing between neighbors are governed by Cal. Civ. Code Sec. 841 and resolved in civil court, not by the city.
Height Limits
Fullerton Municipal Code 15.17.050 caps fences and walls in the front yard setback at 36 inches and along side and rear yards at 6 feet. Non-view-obscuring fences may go to 6 feet in setbacks with Director of Development Services approval.
Key details: Front yard setback: 36 inches (3 feet) max. Side and rear yards: 6 feet max. Grade-difference rule: 6 ft high side / 8 ft low side. Non-view-obscuring in setback: Up to 6 ft with Director approval. Through-lot rear at dedicated frontage: Up to 8 ft.
Building a fence taller than allowed by FMC 15.17.050 or its Table 15.17.050.F is a violation of the Zoning Code. The Code Enforcement Division of the Development Services Department investigates complaints, can issue Notices of Violation, and may pursue administrative citations and abatement under Title 15 of the FMC. Solid view-obscuring fences over 36 inches in a front yard, or fences over six feet in side/rear yards without a height exception, must be lowered, removed, or brought into conformance.
Fence Permit Requirements
Under Fullerton Municipal Code 14.04.050, masonry or concrete fences three feet or shorter and all other fences six feet or shorter are exempt from building permits. Taller fences and most retaining walls still require a permit and zoning review.
Key details: Wood/vinyl/wrought-iron fence: No permit if <=6 ft (FMC 14.04.050). Masonry/concrete fence: No permit if <=3 ft. Over those heights: Building permit required. Retaining wall front yard: >3 ft needs Director approval. Retaining wall side/rear: >4 ft needs Director approval.
Constructing a fence over six feet (or over three feet for masonry/concrete) or any retaining wall over the threshold heights without the required building permit is a violation of FMC 14.04.050 and the California Residential Code as adopted by Fullerton. Building & Safety and Code Enforcement may issue stop-work orders, require permit application and inspection, assess plan-check and double permit fees, and order removal of work that cannot be brought into compliance. Zoning Code violations (e.g., front-yard fence height or vision-clearance) are separately citable under Title 15.
Neighbor Fence Rules
Fullerton defers to California Civil Code Sections 841-841.4 (Good Neighbor Fence Act) for shared boundary fence disputes. Adjoining property owners share equal responsibility for maintaining a reasonable boundary fence. The city does not mediate private fence disputes but enforces zoning compliance.
Key details: Governing Law: CA Good Neighbor Fence Act. Cost Sharing: Equal responsibility presumed. Notice Required: 30 days written before work. City Role: Zoning enforcement only. Code Enforcement: (714) 738-6856.
The city does not enforce private boundary fence disputes. Neighbors should resolve cost-sharing disputes through direct negotiation, mediation, or small claims court. Code Enforcement at (714) 738-6856 only enforces zoning compliance (height, materials, setbacks).
Fullerton is more permissive than most cities when it comes to neighbor fence rules. That said, there are still limits.
The Bottom Line
Fullerton'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 Fullerton is broadly strict or permissive.
Keep in mind that Fullerton 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.
