Driveway Gates in Los Angeles: Setback, the Right-of-Way Permit and Gate Safety

A driveway gate looks like a product you buy. In Los Angeles it is closer to a small permitted structure that happens to move, and it sits at the boundary between three different sets of rules: zoning, the public right of way, and gate safety.

Most of the gates that get into trouble here did not fail because of the steel. They failed because of where they were put.

The first question: where does your property actually end?

Almost every homeowner assumes the property line is at the sidewalk or the back of the curb. It usually is not.

In much of Los Angeles the public right of way extends past the sidewalk and into what looks like your front yard, sometimes by several feet. That strip is city land. Building on it, or swinging a gate over it, is not a zoning question at all.

This is the single most useful thing to check before designing anything at the front of a property, and it is also the thing that most often turns a simple gate into a longer conversation.

The right-of-way permit almost nobody expects

When a front yard fence, a non-retaining wall or a gate encroaches into the public right of way, the Bureau of Engineering handles it through a revocable permit, usually called an R-permit.

Two things about it are worth understanding.

First, the tiers. A front yard fence, wall or gate that conforms to the Zoning Code is generally processed as a Tier 1 revocable permit. If the case needs a field investigation, it moves to Tier 2, with a higher fee and a longer timeline.

Second, and more important: the word revocable is not decoration.

A revocable permit means the city has allowed a private object on public land and can require its removal later, at the owner's expense, if the city needs that land. It is not a defect in the process, it is the nature of the arrangement. But it is worth knowing before you spend serious money on a gate that sits on city property rather than on yours.

Where there is a choice, building entirely within your own property is the version that does not carry that condition.

Setback: the rule that exists to keep a car out of the street

A gate that opens directly onto the sidewalk creates a predictable situation: the driver stops, the car waits, and the back half of it is in the traffic lane or across the sidewalk.

So the governing principle is simple. A vehicle arriving at the gate has to be able to wait completely clear of the roadway, without blocking the sidewalk or a crosswalk.

The Department of Transportation's driveway design guidance puts a number on it, and the number depends on the street. On an arterial the expectation is on the order of twenty feet back from the curb face or edge of roadway, so that a vehicle can stop in front of the gate and out of traffic. On a quiet residential street the required depth is usually less.

This is the constraint that kills more gate designs than any other, because on a short driveway there may simply not be twenty feet to give. When that happens, the honest answers are a sliding gate rather than a swing gate, a gate set further back at the garage rather than at the street, or no gate.

Swing, slide or cantilever, and why the driveway decides

• A swing gate is the cheapest and the most common, and it needs the most room: clear space for the leaves to open, and level ground through the arc

• A sliding gate needs length alongside the driveway for the gate to retract into, which many lots do not have either

• A cantilever slide carries its own weight on a counterbalance and does not run on a ground track, which matters on a driveway that slopes or that would fill a track with debris

• A bi-folding or telescopic gate costs more and exists precisely because the first three do not fit

The slope of the driveway is usually the deciding factor, and it is the one that gets measured last. A swing gate on a driveway that rises toward the house will bind, and no amount of hardware fixes geometry after the fact.

Height: your gate is a fence

For height purposes the Zoning Code treats a gate the same way it treats a fence, which in a required front yard means 3 feet 6 inches. That surprises people who have seen plenty of tall gates around the city. The rules, and the route to going taller, are in fence height rules in Los Angeles.

The tall gates you see are generally in one of three situations: they sit behind the required front yard rather than in it, they went through the Planning approval for greater height, or they are simply non-conforming and nobody has complained yet. The third is a real category, and it is also the one that becomes a problem during a sale.

Automatic gates: the safety standards are not optional

An automated gate is a powered machine that moves a heavy object across a space people walk through. The industry has two standards that matter, and they cover different halves of the job.

• UL 325 governs the gate operator: entrapment protection, how the operator must detect an obstruction, and how it must behave when it does

• ASTM F2200 governs the gate itself: how it is built and installed, including the screening and clearances that stop a person being caught by the moving gate

An operator that meets UL 325 fitted to a gate that does not meet ASTM F2200 is not a safe installation. Both halves have to be right, and the sensors have to be installed and aimed correctly rather than simply present.

This matters most where children and pets are around, which is to say at a residential driveway. It is also the area where the cheapest quote and the correct installation differ the most, and where the difference is invisible until something goes wrong.

Emergency access, and the things that come after the gate

If the gate crosses a route the Fire Department relies on, the Fire Department has its own requirements, including approved emergency access hardware so that a gate can be opened when the power is out and nobody is home.

Plan for the power failure generally. A gate with no manual release, no battery backup and no key override is a gate that will eventually trap a car on the wrong side of it.

The same goes for deliveries, trash collection and anyone who needs to reach the property on foot. A gate is a permanent change to how the address works, not just to how it looks.

What else usually comes with the job

A gate at a driveway rarely arrives alone. The posts need real foundations, there is usually a conduit run for power and the intercom, the driveway approach at the curb may be its own separate permit through the Bureau of Engineering, and commercial sites often add protection for the gate mechanism and the posts, which is where bollards come in.

The gate itself is fabrication, and the same considerations about steel, galvanizing and coastal exposure apply as for any exterior metalwork: metal fabrication services in Los Angeles. If the same project also has stairs or a raised deck behind the gate, the numbers for those are in guardrails and metal railings.

That is the argument for having a general building contractor run it rather than a gate supplier: the gate is one of six things, and the other five are concrete, electrical, permits and the public right of way.

Common questions

Do I need a permit for a driveway gate?

Usually more than one, and they come from different places. Zoning governs the height, the Bureau of Engineering governs anything in the public right of way, and the structural and electrical work has its own permits. Whether all of them apply depends on where the gate sits.

My driveway is short. Can I still have a gate?

Sometimes, with a sliding gate or by moving the gate back toward the house. Sometimes the honest answer is that a gate at the street would put a car in the road, and that it should not be built.

Can I automate an existing gate?

Often, but the gate has to be suitable. Many older gates do not meet the current standards for an automated installation, and adding an operator to them creates the entrapment risk those standards exist to prevent.

What does it cost?

Span, material, swing or slide, the foundations, how far the power has to run, the automation and access control, and which permits are in play all move it substantially. Rather than publish a figure that would be wrong for your driveway, we will look at it with you.
