Los Angeles / LA County at a Glance
California Law: Two of Seven Safety Features
The state rule is the Swimming Pool Safety Act, Health and Safety Code (HSC) sections 115920 to 115929. When a building permit is issued for a new pool or spa, or a remodel, at a single-family home, HSC 115922 requires at least two of seven features:
- An enclosure meeting HSC 115923 that isolates the pool from the house
- Removable mesh fencing meeting ASTM International (ASTM) standard F2286, with a self-closing, self-latching gate that takes a key lock
- A safety cover labeled as meeting ASTM F1346-23
- Exit alarms on the house doors and windows that open directly to the pool
- Self-closing, self-latching devices on those doors, with the release at least 54 inches above the floor
- A pool alarm certified to ASTM F2208 (alarms worn by a child do not count)
- Another means at least as effective, verified by an approved testing laboratory
Some pairings do not count as two, such as a safety cover with a pool alarm (SB 552, effective January 1, 2025). An enclosure under HSC 115923 is at least 60 inches high, with no more than 2 inches at the ground, no gap a 4-inch sphere passes, and gates that open away from the pool and self-close with a latch no lower than 60 inches.
The state does not require an enclosure. The City of Los Angeles and unincorporated LA County do: see below.
Who Enforces What in Los Angeles
Where your address sits decides which local rules apply on top of the state Act.
| Area | What we verified |
|---|---|
| City of Los Angeles | LAMC 91.3109.4 requires residential pools on lots with one to three homes to be completely enclosed, and 91.3109.4.1 sets the barrier at 60 inches with no more than 2 inches at the ground. A pool with a power safety cover, or a spa with a safety cover, meeting ASTM F1346 is exempt. Existing pools and other bodies of water 18 inches or deeper need a fence at least 4½ feet high with a self-latching gate (LAMC 91.6109). Permits come from the Department of Building and Safety (LADBS). |
| Unincorporated LA County | Public Works' Building Code Manual 3109.2 (April 22, 2025) says County Code Title 11, Chapters 11.50 and 11.51, require every new or altered pool to have an enclosure that completely surrounds it: at least 60 inches high, no more than 2 inches at the ground, and a latch release no lower than 60 inches. Double gates, gates over 4 feet wide and driveway gates are not allowed as enclosure gates. |
| Long Beach, Pasadena, Glendale, Burbank, Santa Monica and other cities | Each has its own building department and may have its own local rules on top of the state Act. Ask yours before you design. |

Frequently Asked Questions
Los Angeles Pool Fencing: Two Rulebooks at Once
California's law is about safety features; LA's local codes are about enclosure. In the city and in unincorporated county areas, a new or remodeled pool needs both: a 60-inch barrier around the pool, and two of the state's seven features. The barrier counts as one of the two only if it isolates the pool from the house.
Settle both at the design stage. Decide how the barrier runs relative to the house doors, then pick the second feature to match, before you submit plans.
