California Pool Fence Requirements at a Glance
State and local laws change. This information reflects our best research as of September 2026, but you must confirm current requirements with your local building department before installing or modifying any pool barrier. The Swimming Pool Safety Act applies statewide, and cities and counties can add rules on top of it; San Jose, Sacramento, Riverside and Palm Springs do.

California Pool Barrier Law
California's Swimming Pool Safety Act, Health and Safety Code (HSC) §115920 to §115929, applies when a building permit is issued to build a new pool or spa, or remodel an existing one, at a private single-family home. It covers pools and spas holding water more than 18 inches deep, in the ground or above it.
Under HSC §115922(a), the pool or spa must have at least two of these seven drowning prevention safety features:
- An enclosure that meets §115923 and isolates the pool or spa from the house
- Removable mesh fencing meeting ASTM International (ASTM) standard F2286, with a self-closing, self-latching gate that can take a key lock
- A manual or power safety cover labeled as meeting ASTM F1346-23
- Exit alarms on the house doors and windows that open directly onto the pool or spa
- 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 that sounds when someone enters the water. Alarms worn by a child do not count
- Another means of protection at least as effective, verified by an approved testing laboratory to a recognized standard and labeled
Three pairings do not count as two features: an exit alarm and a self-closing latch on the same door, an exit alarm on one door and a latch on another, and a safety cover with a pool alarm. The local building official inspects the features before giving final approval. [HSC §115922(b), (c)]
The 60-inch figure belongs to the enclosure. If you choose one, HSC §115923 requires it to be at least 60 inches high, with no more than 2 inches of clearance at the ground, no gap a 4-inch sphere can pass through, no handholds or footholds a child under 5 could use to climb, and gates that open away from the pool, self-close, and have a self-latching device no lower than 60 inches above the ground. The state does not require an enclosure: a safety cover plus exit alarms, for example, also meets the Act. Some cities go further: Los Angeles, San Jose, Sacramento, Riverside and Palm Springs all require an enclosure (see below).
The Act does not apply to public pools, to hot tubs and spas with locking safety covers meeting ASTM ES 13-89, or to apartment complexes and other settings besides single-family homes. [HSC §115925]
Above-Ground Pools in California
The Act defines a swimming pool as any structure for swimming or recreational bathing with water more than 18 inches deep, including above-ground pools, hot tubs, spas and portable spas. When a building permit is issued for one at a single-family home, the two-feature rule applies.
The pool wall itself is not one of the seven features, so an above-ground wall does not count toward the two, however tall it is. One compliant pairing is a 60-inch enclosure meeting §115923, or ASTM F2286 removable mesh fencing with a self-closing, self-latching, key-lockable gate, plus exit alarms on the doors and windows that open onto the yard.
The Act is triggered by a building permit. Whether a portable or soft-sided pool needs one is up to your local building department, so ask before you set it up.
California requires two of seven safety features for permitted pools, and cities can add their own rules. Confirm which features your building department accepts before installing.
City & County Variations in California
The Act sets the state baseline, and cities and counties can add their own rules. The rows below come from local codes where we found them. Where we have not verified local details, we point you to our city guide.
| City / County | Requirements & Permit Notes |
|---|---|
| Los Angeles City of Los Angeles | The Los Angeles Municipal Code (LAMC) requires residential pools on lots with one to three homes to be completely enclosed, with a barrier at least 60 inches high and no more than 2 inches of ground clearance (LAMC 91.3109.4 and 91.3109.4.1). A pool with a power safety cover, or a spa with a safety cover, meeting ASTM F1346 is exempt. Existing pools, fish ponds 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). |
| San Diego | The City of San Diego's Information Bulletin 712 (June 2021) requires pool site plans to show every barrier, its height and its gates. The county publishes its rules for unincorporated areas in form PDS 379. See our San Diego guide. |
| San Jose Santa Clara County | The city's Permit Center (April 2026) requires a new or remodeled pool or spa on a single-family property to be completely enclosed and to have at least two more drowning prevention features (City Code Chapter 17.28). Unincorporated Santa Clara County requires a complete enclosure at least 5 feet high (County Code B18). |
| Sacramento | City Code 15.64.070 requires every pool to be completely enclosed by a fence at least 5 feet high, and the city's pool form applies the two-feature rule on top. Unincorporated Sacramento County adopts the 2021 International Swimming Pool and Spa Code for residential pools (County Code 16.36). |
| Riverside Riverside County | The City of Riverside requires a barrier at least 60 inches high around the pool (RMC 16.19.020). In unincorporated Riverside County, the county's barrier letter (December 2025) requires two barriers: a 5-foot primary enclosure and a secondary feature, with mesh allowed only as the secondary. |
| Palm Springs | The city's building code amendment makes the enclosure one of the two required features in every case (City Code 8.04.015, CBC 3109.2.1). |
| Fresno | We found no added city enclosure rule. The city's consumer notice requires barriers and alarms to be inspected and approved before the pool is plastered or filled. |
| Other cities | Ask your building department whether it has local pool enclosure rules in addition to the state Act. |

Pool Fence Cost in California
We found no published source that prices pool fences by state or city, so these are national installed ranges from our pool fence cost guide. Quotes where you live can land above or below them.
| Material | Installed, per linear foot | Full breakdown |
|---|---|---|
| Removable mesh | $15 to $35 | Mesh fence cost |
| Aluminum | $30 to $60 | Aluminum fence cost |
| Vinyl / PVC | $20 to $45 | Vinyl fence cost |
| Tempered glass | $90 to $500 | Glass fence cost |
National typical installed ranges, not quotes. Multiply by your fence perimeter. Some sources include one gate in the figure; extra gates, permits and hard deck surfaces add to the total.

California Pool Fencing: SB 552 and Local Enforcement
California's Swimming Pool Safety Act is a statewide law, but local building departments enforce it at the permit, and the rules have tightened. Since January 1, 2018, under SB 442, permitted new and remodeled pools at single-family homes need two of the seven features rather than one. SB 552, signed September 27, 2024 and effective January 1, 2025, amended the feature list, including the ASTM F1346-23 cover standard, and set out the pairings that do not count as two features.
SB 442 also reached home sales: a home inspection of a property with a pool or spa must identify which of the seven features it has, under Business and Professions Code §7195.
Because California requires two of its seven drowning prevention features, plan both before the inspection.
