Pools and spas when you buy or sell in California: the pool safety law in plain words

Short answer: California's Swimming Pool Safety Act says that when a building permit is issued to build a new pool or spa at a single-family home, or to remodel one, it needs at least two of seven safety features. Those include a fence around the pool, a safety cover and door alarms. The law ties this to a permit, not to a sale. When a home with a pool or spa is sold, though, the inspection report has to list which of the seven features it has. It also has to say so if there are fewer than two.

I'm Weston Clark, a real estate agent with Compass in San Diego. A lot of homes around here have a pool or a spa. When one of my clients buys or sells one, the same questions come up. Does the pool need a fence? What will the inspector say? Do we have to fix anything before closing? The answers are in a short state law, so here's what it says, quoted, and what it means in everyday words. I'm not a lawyer, and this isn't legal advice. Your inspector and your city's building department have the final word on your home.

What counts as a pool

The law starts with a definition. Health and Safety Code section 115921 says: "'Swimming pool' or 'pool' means any structure intended for swimming or recreational bathing that contains water over 18 inches deep." It adds that this "includes in-ground and aboveground structures and includes, but is not limited to, hot tubs, spas, portable spas, and nonportable wading pools."

In plain words: if it holds water more than 18 inches deep and people get in it, it counts. That's true whether it's dug into the ground or sits above it. A backyard hot tub counts too.

When the safety rule applies

Here's the main rule, from section 115922. When "a building permit is issued for the construction of a new swimming pool or spa or the remodeling of an existing swimming pool or spa at a private single-family home," the pool or spa "shall be equipped with at least two of the following seven drowning prevention safety features."

Put simply: if you get a permit to build a new pool or spa, or to remodel one, at a house, you need at least two of the seven safety features listed below. A building permit is the city's approval to do construction work. The law was last updated effective January 1, 2025.

The same section says that before the work gets its final sign-off, "the local building code official shall inspect the drowning safety prevention features required by this section." That means the city's building inspector checks the features before the job is approved as done.

And section 115924 says anyone "entering into an agreement to build a swimming pool or spa, or to engage in permitted work on a pool or spa covered by this article, shall give the consumer notice of the requirements of this article." In everyday words: your pool contractor has to tell you about these rules when you hire them.

Notice what the rule doesn't say. It doesn't list selling a home as a reason to add features. Under this state law, the trigger is a permit for new or remodel work. Your city can have its own rules, so it's worth asking about your home.

The seven safety features

Here's each one from section 115922, with what it means:

A pool fence. The law says "An enclosure that meets the requirements of Section 115923 and isolates the swimming pool or spa from the private single-family home." That's a fence or wall between the house and the pool. The next section explains what makes it count.
Removable mesh fencing. "Removable mesh fencing that meets the ASTM International F2286 standard in conjunction with a gate that is self-closing and self-latching and can accommodate a key lockable device." ASTM is a group that writes product standards. This is a mesh fence you can take down, with a gate that closes and latches on its own and can take a lock.
A safety pool cover. "A manually operated or power-operated safety pool cover that is accompanied by a label verifying that the cover meets the specifications of the ASTM International F1346-23 standard." It can be manual or motorized, but it needs a label showing it meets that standard.
Exit alarms. Alarms on "doors and windows that provide direct access to the swimming pool or spa without any intervening enclosure." The law says they sound a steady alarm or "a repeating verbal warning, such as a notification that 'the door to the pool is open.'" They can run on batteries or be wired in.
Self-closing, self-latching doors. "A self-closing, self-latching device with a release mechanism placed no lower than 54 inches above the floor" on doors that open straight to the pool. In other words, the door closes and latches on its own, and the release is at least 54 inches up.
A pool alarm. "An alarm … that, when placed in a swimming pool or spa, will sound upon detection of accidental or unauthorized entrance into the water." It has to be certified to the ASTM F2208 standard. The law also says an alarm a person wears "is not a qualifying drowning prevention safety feature."
Other protection that works as well. The law allows "Other means of protection" if it protects at least as well as the others. It also has to be checked by an approved testing lab and come with a label showing it meets the standards.

Pairs that don't count as two

Section 115922 also says some pairs don't meet the rule:

"An exit alarm and a self-closing, self-latching device on the same door."
"An exit alarm and a door latch on separate doors."
"A safety pool cover and an alarm described in paragraph (6)," meaning the pool alarm.

Simply put, those combinations won't add up to the two features the law asks for. Your contractor and the building inspector will know which pairs work for your layout.

What makes a pool fence count

Section 115923 says the fence or wall has to have all of these:

Gates that "open away from the swimming pool, and are self-closing with a self-latching device placed no lower than 60 inches above the ground."
"A minimum height of 60 inches." That's 5 feet tall.
"A maximum vertical clearance from the ground to the bottom of the enclosure of two inches." So no more than a 2-inch gap at the bottom.
Openings that "do not allow passage of a sphere equal to or greater than four inches in diameter." In plain words, no gap a 4-inch ball could fit through.
An outside "free of protrusions, cavities, or other physical characteristics that would serve as handholds or footholds that could enable a child below the age of five years to climb over." That means nothing on the outside that makes it easy to climb.

What the law doesn't cover

Section 115925 says "The requirements of this article do not apply to any of the following":

"Public swimming pools."
"Hot tubs or spas with locking safety covers that comply with the ASTM International F1346 standard."
"An apartment complex, or any residential setting other than a single-family home."

In everyday words: this law is about pools and spas at houses. A spa with a locking cover that meets the standard is left out. So is a shared pool at a condo or apartment building. If you're buying a condo, the homeowners association can tell you about the shared pool. My HOA guide explains what to ask for.

What your home inspector checks

This is the part that touches almost every sale of a home with a pool. California's home inspector law, Business and Professions Code section 7195, says that when a home with a pool or spa is sold, "an appropriate inspection shall include a noninvasive physical examination of the pool or spa and dwelling for the purpose of identifying which, if any, of the seven drowning prevention safety features" the pool or spa has.

It also says what goes in the written report. The report "shall identify which, if any, of the seven drowning prevention safety features … the pool or spa is equipped with and shall specifically state if the pool or spa has fewer than two." It notes "whether those features are in place, in good repair, operable as designed, and, if applicable, appropriately labeled." And it includes a statement that a pool fence "is the most studied and effective drowning prevention safety feature for preventing a child from accessing a pool or spa unsupervised, according to the American Academy of Pediatrics."

Put simply: a home inspector looks at the pool and the house and writes down which of the seven features are there and whether they work. If there are fewer than two, the report says so plainly. "Noninvasive" means the inspector looks and tests without taking anything apart. The law also says the inspector doesn't have to decide whether each feature meets the detailed product standards. My home inspection guide covers the rest of the inspection.

If you're buying a home with a pool or spa

Read the pool section of the report. It will list the features and say if there are fewer than two. That gives you a clear picture before you remove your inspection contingency. That's the part of your offer that lets you back out or ask for repairs after the inspection.
Ask about permits. Ask the seller whether the pool or spa was built or remodeled with permits, and when. Permit records show what work the city approved.
Plan ahead for a remodel. If you want to redo the pool after closing and the work needs a permit, the two-feature rule applies to that job. It's easier to plan for it from the start.
Ask the inspector. If something in the pool section isn't clear, ask the inspector to walk you through it. They can show you what each feature looks like on that home.

If you're selling a home with a pool or spa

Expect the report to cover it. The buyer's inspector will list which features your pool or spa has. It helps to know your answer before you list.
If you're planning a pool remodel before you list, and it needs a permit, plan for at least two features as part of the job. The building inspector checks them before final approval, so leave time for that.
Share what you know. If you have permits or records for the pool, keep them handy. My disclosures guide covers what sellers share in writing, and my seller prep guide covers getting ready to list.
Selling as-is? The inspection still happens, and the pool section is still in the report. My as-is guide explains what that means for you.

Getting the small safety items done early makes escrow, the stretch between an accepted offer and closing, go more smoothly. My guide to smoke alarms and water heater straps covers the other safety items California asks about when you sell.

Common questions

Do I have to add a pool fence before I sell my home in California?

Not because of the sale by itself. The state's Swimming Pool Safety Act ties its rule to a building permit. That means a permit to build a new pool or spa at a single-family home, or to remodel one. That's when the pool needs at least two of seven safety features, and a fence that meets the law is one of them. Your city can have its own rules, so ask your inspector or the city's building department about your home.

What are the seven pool safety features?

There are seven. A fence or wall between the pool and the house. Removable mesh fencing with a gate that closes and latches on its own. A labeled safety pool cover. Exit alarms on doors and windows that open to the pool. Self-closing, self-latching devices on those doors. A certified pool alarm that sounds when someone gets in the water. And other tested, labeled protection that works at least as well.

Does a hot tub or spa count as a pool under this law?

Yes. The law defines a pool as any structure for swimming or bathing with water over 18 inches deep, and it names hot tubs and spas. One exception: the law doesn't apply to hot tubs or spas with locking safety covers that meet the ASTM F1346 standard.

Will my home inspector check the pool safety features?

Yes. When a home with a pool or spa is sold, California law says the inspection report has to list which of the seven features it has. It has to say so clearly if there are fewer than two, and note whether the features are in good repair and working.

Does the pool safety law apply to condos?

No. The law says it doesn't apply to an apartment complex or any home other than a single-family home, and it doesn't cover public pools. If you're buying a condo with a shared pool, ask the homeowners association about it.

If I remodel my pool before I sell, do I need to add safety features?

If the work needs a building permit, yes. The law says a pool or spa remodel at a single-family home with a building permit needs at least two of the seven features. The building inspector checks them before giving final approval, so plan for them early.
