What are the pool fence rules in California?

Updated November 2026

When a building permit is issued for a new pool or spa, or for remodeling one at a single-family home, California's Swimming Pool Safety Act requires at least two of seven drowning prevention features. An enclosure is one of them, and it has to be at least 60 inches tall, leave no gap a 4-inch sphere can pass, and have self-closing, self-latching gates that open away from the pool.

What are the seven safety features?

Health and Safety Code section 115922 lists them, as of November 2026:

An enclosure that meets section 115923 and isolates the pool or spa from the house.
Removable mesh fencing that meets ASTM F2286, with a self-closing, self-latching gate that can take a key lock.
A safety pool cover that meets ASTM F1346.
Exit alarms on doors and windows that open directly to the pool area.
Self-closing, self-latching devices on those doors, with the release at least 54 inches above the floor.
A pool alarm that meets ASTM F2208 (wearable child alarms do not count).
Other means at least as protective, independently verified.

Some pairs do not count as two features, such as a pool cover plus a pool alarm.

What makes an enclosure qualify?

Section 115923 describes it:

At least 60 inches tall.
No more than 2 inches from the ground to the bottom of the fence.
No gaps or openings that let a 4-inch sphere through.
No outside protrusions, cavities or other footholds or handholds a child under five could use to climb over.
Access gates that open away from the pool and are self-closing, with a self-latching device no lower than 60 inches above the ground.

Does this apply to my existing pool?

The state requirement is tied to a building permit for a new pool or spa or a remodel. It is still a good standard for any pool where children may visit. Local building codes can add their own barrier rules, so check with your city.

What about Oakland specifically?

Oakland's local building code amendments leave swimming pool barriers out of the usual fence permit exemption, so plan on a city permit for the barrier. See Oakland fence permits and our pool fences.
