Fence Laws and Permits in LA: What to Know Before You Build

A new fence is a straightforward project — until it isn't. Skip a permit, miss a setback, or build over a property line, and a simple install can turn into fines, legal disputes, or a forced tear-out.

For homeowners in Los Angeles and the San Fernando Valley, here's the checklist worth working through before any contractor breaks ground.

When You Need a Permit in LA

In the City of Los Angeles, LADBS generally requires a permit for fences taller than:

• •3.5 feet: in front yards
• •8 feet: in side and rear yards (some neighborhoods cap at 6 feet)

Pool barriers, retaining walls used as fences, and fences in Hillside Areas or Very High Fire Hazard Severity Zones have additional review requirements regardless of height.

Outside the City of LA, unincorporated parts of the County and individual cities (Calabasas, Hidden Hills, Agoura Hills) apply their own height thresholds. Always confirm with your local building department before assuming.

Property Line Considerations

A property line dispute is one of the most common — and most expensive — fence problems we see.

• •Get a survey.: If you don't have a current survey, get one. Visible markers, old fences, and "where the lawn ends" are not reliable property line indicators.
• •Talk to your neighbors first.: Even when you're 100% on your own land, a courtesy conversation prevents most disputes. Shared fences also fall under California Civil Code Section 841, which governs cost-sharing.
• •Mind the setback.: Many cities require fences to be set back from the property line in certain zones — particularly on corner lots and near intersections, where visibility triangles apply.

Height Restrictions in Practice

For most residential properties in LA:

• •Front yard: 3.5 feet max for solid fencing; up to 42 inches for open picket without a permit
• •Side and rear yard: 6 to 8 feet, depending on jurisdiction
• •Corner lots: Stricter rules to maintain driver visibility
• •Pool barriers: 60 inches minimum, with picket spacing under 4 inches

Hillside neighborhoods often have additional view-protection rules — your fence may not exceed certain heights at certain elevations to preserve neighbor sightlines.

HOA Rules Are Separate

If you're in an HOA community, the city permit is only half the equation. Your CC&Rs and Architectural Guidelines may restrict materials, colors, picket styles, and gate designs — and HOA approval is required before installation.

California Civil Code Section 4765 gives HOAs up to 45 days to respond to a complete application. Submit your HOA package and your city permit application in parallel to keep your timeline tight.

What Happens if You Skip This

The realistic consequences of building without proper permits or approvals:

• •Stop-work orders and fines from LADBS
• •Required removal or modification at your expense
• •HOA fines and liens
• •Disclosure complications when you sell

Permits are cheap. Tear-outs aren't.

How a Good Contractor Helps

An experienced local fence contractor should know the height limits and setback rules for your jurisdiction, prepare a permit-ready site plan, and walk a permit through LADBS or your local building department on your behalf.
