This is general information from a locksmith, not legal advice, and your city or county building inspector has the final word. Check the current law and your local code before relying on it.
When the rules apply
California's Swimming Pool Safety Act, in the Health and Safety Code starting at section 115920, applies to private single-family homes when a building permit is issued to build a new pool or spa, or to remodel an existing one. At that point the pool must have at least two of the seven drowning prevention features listed in section 115922, and an enclosure that meets section 115923, with the right gates, is one of them. A removable mesh fence with a self-closing, self-latching gate that can take a key lock is another. Older pools that are not being built or remodeled are not automatically caught by it, but the same features are what any parent of a small child should want anyway.
What the gate has to do
For an enclosure to count, section 115923 describes gates that:
- open away from the pool,
- are self-closing, so the gate swings shut on its own,
- are self-latching, so it locks itself when it closes,
- and have the latch release placed no lower than 60 inches above the ground, out of a small child's reach.
The enclosure itself must be at least 60 inches high, with no more than 2 inches between the ground and its bottom, no gaps a 4-inch sphere can pass through, and no handholds or footholds a young child could climb. That is a fencing matter rather than a lock one, but it decides whether the gate counts.
Doors from the house
If a door of the house opens straight onto the pool area, one of the listed features is a self-closing, self-latching device on that door with its release no lower than 54 inches above the floor. That is a lock and hardware job we do; the listed alarm options are for an alarm company.
Why gates fail the test
A pool gate that was compliant when it was installed rarely stays that way on its own. Hinge springs weaken so the gate stops short of closing, gates sag so the latch misses the keeper, and someone props it or lowers the latch to make it easier to open. Checking that the gate closes and latches from any open position, every season, is the whole test.
What we fit
- Magnetic and gravity pool gate latches with the release at 60 inches or above.
- Self-closing hinges, adjusted so the gate shuts from any angle.
- Keyed versions, keyed to the house if you want to lock the pool area.
- Gate adjustment so the latch meets the keeper cleanly.
See our gate locks page. We fit hardware built for the job; whether a particular pool passes inspection is for the inspector.
Questions people ask
Does my existing pool have to meet these rules?
Under the state Act, the requirement of two of seven features is triggered by a permit to build or remodel a pool at a single-family home. Local codes and HOA rules can go further, so check with your city or county.
How high does the pool gate latch have to be?
The self-latching device must be no lower than 60 inches above the ground under Health and Safety Code 115923, and the gate must open away from the pool and close by itself.
Can the gate lock with a key as well?
Yes. Many pool latches take a key, and we can key it to the house so one key locks the pool area.
My pool gate no longer closes by itself. Is that a lock problem?
Usually the hinge springs or a sagging gate. Adjusting or replacing the hinges and realigning the gate brings it back to closing and latching on its own.
