How many pool safety features does California require for a home pool?
When a building permit is issued for a new pool or spa, or a remodel of an existing one, at a private single-family home, California Health & Safety Code §115922 requires at least two of seven drowning-prevention features. A fence is only one of the seven. Three pairs do not satisfy the rule: an exit alarm plus a self-closing, self-latching device on the same door; an exit alarm plus a door latch on separate doors; and a safety pool cover plus a pool alarm. The local building official inspects the features before final approval. The section was last amended by SB 552, effective January 1, 2025.
The seven features
Section 115922(a) says that when a building permit is issued for the construction of a new swimming pool or spa, or the remodeling of an existing one, at a private single-family home, it “shall be equipped with at least two of the following seven drowning prevention safety features.” The statute’s “enclosure” means “a fence, wall, or other barrier that isolates a swimming pool from access to the home” (§115921(c)).
| Feature (§115922(a)) | What the statute requires |
|---|---|
| 1. Enclosure | An enclosure that meets §115923 and “isolates the swimming pool or spa from the private single-family home.” |
| 2. Removable mesh fencing | Meets ASTM F2286, “in conjunction with a gate that is self-closing and self-latching and can accommodate a key lockable device.” |
| 3. Safety pool cover | Manual or power-operated, “accompanied by a label verifying that the cover meets the specifications of” ASTM F1346-23. |
| 4. Exit alarms | On the home’s doors and windows that give direct access to the pool or spa without an intervening enclosure. When opened or left ajar they make a continuous audible alarm or a repeating verbal warning. Battery-operated or wired. |
| 5. Self-closing, self-latching device on home doors | On the doors that give direct access to the pool or spa, with the release mechanism “no lower than 54 inches above the floor.” |
| 6. Pool alarm | In good repair, sounds on accidental or unauthorized entrance into the water, and “meet and be independently certified to” ASTM F2208. An alarm attached to a child, designed for individual use, “is not a qualifying drowning prevention safety feature.” |
| 7. Other means of protection | Equal or greater protection than the features above, independently verified by an approved testing laboratory against ASTM, ASME or another nationally recognized standards body, and labeled. |
Three pairs that do not count
Section 115922(b) says the requirement “is not satisfied by any of the following”:
| Pair that does NOT satisfy the rule (§115922(b)) | In plain terms |
|---|---|
| (1) An exit alarm and a self-closing, self-latching device on the same door | Features 4 and 5 combined on the same door. |
| (2) An exit alarm and a door latch on separate doors | An exit alarm (feature 4) on one door and a door latch on another. |
| (3) A safety pool cover and an alarm described in paragraph (6) | Features 3 and 6 together. |
Two different heights: 54 inches and 60 inches
The 54-inch figure applies to the release mechanism on a self-closing, self-latching device on the home’s doors (feature 5). The 60-inch figures apply to a feature-1 enclosure: the fence itself and the latch on its gates.
| Enclosure rule (§115923) | Requirement |
|---|---|
| Gates | Open away from the pool, self-closing, with a self-latching device “no lower than 60 inches above the ground.” |
| Height | Minimum 60 inches. |
| Ground clearance | Maximum vertical clearance from the ground to the bottom of the enclosure: 2 inches. |
| Gaps | Gaps or voids, if any, must not allow passage of a sphere 4 inches in diameter or larger. |
| Outside surface | No protrusions, cavities or other characteristics that serve as handholds or footholds that could enable a child under five to climb over. |
Inspection and exemptions
- Inspection: before final approval of the permitted work, “the local building code official shall inspect the drowning safety prevention features required by this section and, if no violations are found, shall give final approval” (§115922(c)).
- Not covered: public swimming pools; hot tubs or spas with locking safety covers that comply with ASTM F1346; and an apartment complex or any residential setting other than a single-family home (§115925).
- Safety cover wording: the statute says “safety pool cover” with an ASTM F1346-23 label. It does not use the word “net.” Whether a product sold as a pool net qualifies depends on whether it carries that label and is a cover under the statute’s terms. Confirm with the building official.
- When it applies: the rule is triggered “when a building permit is issued.” The text we read does not mention existing pools that are not being permitted. Ask your building department about your situation.
Other pool permit rules in the same article
For a new pool or spa, §115928 requires suction outlets set up to provide circulation (at least two hydraulically balanced outlets per pump at least three feet apart, or alternatives such as skimmers or perimeter overflow) and covered with anti-entrapment grates that cannot be removed without tools. For a remodel or modification of an existing pool, toddler pool or spa, §115928.5 says the permit shall require upgrading existing suction outlets with anti-entrapment grates. Anyone contracting to build or do permitted work on a pool or spa must give the consumer notice of the article’s requirements (§115924(a)).

It does not say which two features are cheapest or best, and it gives no prices. It is not legal advice, and your local building department applies the code to your project. For the City of San Diego process see pool fence permit in San Diego, the pool fence requirements and the code checklist.
Questions
How many pool safety features does California require for a home pool?
At least two of seven, when a building permit is issued for a new pool or spa, or a remodel of an existing one, at a private single-family home (Health & Safety Code §115922(a)).
Does a fence count as one of the two features?
Yes. An enclosure meeting §115923 that isolates the pool or spa from the home is feature 1. Removable mesh fencing with a self-closing, self-latching gate is feature 2.
Which pairs of safety features do not satisfy the rule?
Three: an exit alarm and a self-closing, self-latching device on the same door; an exit alarm and a door latch on separate doors; and a safety pool cover and a pool alarm (§115922(b)).
Does a pool safety net count?
The statute names a “safety pool cover” that carries a label verifying it meets ASTM F1346-23. It does not use the word “net.” Ask your building official whether a specific product qualifies.
What height must a California pool fence be?
At least 60 inches, with no more than a 2-inch gap under the bottom, no gap that passes a 4-inch sphere, and gates that open away from the pool and self-close and self-latch with the latch no lower than 60 inches above the ground (§115923).
