Do you need a permit for a fence or block wall in Los Angeles?

In the City of Los Angeles, a block, brick, stone or concrete wall over 3.5 feet needs a building permit. Wood and wrought iron fences need one only over 10 feet. One design skips the permit up to 6 feet: masonry pilasters with open wrought iron or wood between them. Zoning height limits still apply to every fence, permit or not.

Two rules are at work. The fence permit turns on material and height, and zoning sets the height for each yard. We check both for the address before we design a block wall along a property line.

Which rule applies to your fence or wall?

Each row is one case. City rows apply inside the City of Los Angeles only.

How tall can a fence or wall be in each yard?

LADBS bulletin P/ZC 2023-002 lays out fence heights in the required yards. The front yard allows 3.5 feet in R zones and 6 feet in A and RA zones. A front yard fence can reach 8 feet only with City Planning approval.

Side and rear yards have their own limits. On a lot 40 feet wide or more outside a Hillside Area, the limit is 8 feet. On a narrower lot, or any lot in a Hillside Area, it is 6 feet.

Height is measured from the natural ground next to the fence. On sloping ground, the bulletin has its own method for the maximum height. Hedges count too, since the zoning code treats hedges and thick shrubs as a fence or wall. ZIMAS, the city’s Zone Info Map Access System, shows which zone your parcel is in.

When does a block wall need a permit?

LADBS, the city’s Department of Building and Safety, issues the building permit. Its bulletins treat a freestanding block, brick or stone wall as a masonry fence. Those need a permit over 3.5 feet, and so does any swimming pool barrier.

LADBS bulletin P/BC 2026-080 describes a fence that needs no permit up to 6 feet. Masonry or concrete pilasters can be up to 6 feet tall and 1 foot 4 inches wide. They must stand at least 6 feet apart, center to center. We build the brick pilasters and low wall sections for these fences, with caps to match the house.

Between the pilasters, solid masonry can rise to 3 feet 6 inches. Everything above that has to be open wrought iron, wood or another lightweight material. No part of the fence can top 6 feet, and a pool barrier never qualifies.

That exemption covers the building permit only. Zoning still applies, so in an R-zone front yard even a pilaster fence stops at 3.5 feet. The full 6 foot version fits side and rear yards, or a front yard where zoning allows it.

Is the sidewalk edge your property line?

Not always. The LADBS fence bulletin warns against assuming the inside edge of the sidewalk is the property line. In the city, the parkway strip and the sidewalk are part of the public right of way. If the line is in doubt, a property survey settles it before a footing goes in.

In the right of way, the fence permit is a Revocable Permit from the Bureau of Engineering. The Bureau applies the same zoning heights there as on private land. On private land, LADBS issues the permit instead.

An over-height fence in the right of way needs a City Planning variance first. The same goes inside a Fence Height District (LAMC 13.10) or a Historic Preservation Overlay Zone (HPOZ). Without the variance, the Bureau will not issue the permit. Specific Plans and other overlays can add their own fence rules too.

What if you live outside the City of Los Angeles?

Sherman Oaks, Hollywood, Brentwood, Bel Air and Pacific Palisades are inside the City of Los Angeles. The city rules above apply there. Altadena and La Crescenta-Montrose are different: they are unincorporated, so LA County rules apply.

For a freestanding fence or block wall, County Public Works puts the fence permit line at 6 feet. A 7 or 8 foot concrete wall needs a permit and inspection. A wall that holds back any soil may need a permit even under 6 feet.

The County’s Department of Regional Planning also limits where and how high a wall can go. Its approval can depend on whether the fence stands in the front, side or back yard.

Glendale, Burbank, Pasadena, San Marino, Beverly Hills and Santa Monica are separate cities with their own fence rules. The County’s advice there is to check with the city’s planning department.

Is it a fence or a retaining wall?

Everything above is about walls that stand free. Once a wall holds back soil, it is a retaining wall with its own permit rules. Our guide to permits for walls that hold back soil covers those.

Quick check: if the soil sits higher on one side of the wall, the wall is holding soil back. That puts it in the same category as our retaining walls built for sloped lots.

Who pays for a fence or wall on the property line?

For a fence dividing two properties, California Civil Code 841 sets the starting point. The Good Neighbor Fence Act of 2013 rewrote it. The statute presumes adjoining landowners share an equal benefit from that fence. Unless they agree otherwise in writing, each is presumed equally responsible for its reasonable costs.

A landowner who plans to spend on the fence must give each adjoining landowner 30 days of written notice first. The notice names the problem, the proposed fix, the estimated cost, the proposed split and a timeline. For a sense of the numbers, see what a block wall costs per linear foot.

The equal share is a starting presumption. A court can order a smaller share, or none, if an equal split would be unjust. Before work starts, we suggest a short written agreement with your neighbor that sets out the plan and the split.

How the permit question fits into your wall project

We settle the fence permit question for the address before we design a wall. In the city, LADBS reviews the plans for a fence before it issues the permit.

The permit is handled as part of the job, with the paperwork filed for you where the agency allows it. One Yelp reviewer wrote that we came out the same day to measure and quote a brick fence rebuild. Every wall starts with a site visit, and the height limit and permit path go into your free written quote.
