Spa and Hot Tub Inspection Requirements in California
California treats a spa or hot tub as a swimming pool under HSC §115921, so the two-of-seven safety feature rule and the BPC §7195 report apply, unless the spa has a locking safety cover that complies with ASTM F1346 (HSC §115925(b)).
A hot tub or spa is a swimming pool in California. Health and Safety Code §115921 defines a pool as any structure for swimming or bathing over 18 inches deep, and names hot tubs, spas and portable spas. The two-of-seven feature rule in HSC §115922 and the BPC §7195 report apply to a spa, except that HSC §115925(b) excludes a spa with a locking safety cover complying with ASTM F1346.
This guide covers what that definition and that exemption mean at a building permit and at a property transfer, what the inspection report must say about a spa, how the seven features read when the water is a spa, and what an inspector records about the spa's equipment.
A spa is a pool under the Swimming Pool Safety Act
The Swimming Pool Safety Act is Article 2.5 of the Health and Safety Code, sections 115920 to 115929, in force since January 1, 1997. Its definitions section, HSC §115921, settles the first question a spa owner asks: the article does not have a separate category for hot tubs. Every reference to a pool in the article includes a spa.
Structure
Covered by HSC §115921?
Why

HSC §115925(a) exempts public swimming pools
Two consequences follow. When a building permit is issued for a new spa or for remodeling an existing one at a single-family home, HSC §115922(a) requires the spa to be equipped with at least two of the seven drowning prevention safety features, and under §115922(c) the local building official inspects those features before final approval. When the property is transferred, BPC §7195 requires a home inspection to include a noninvasive examination of the spa and the report to identify which of the seven features it has.
The locking cover exemption in HSC §115925(b)
HSC §115925 lists three things the article does not apply to: public swimming pools, hot tubs or spas with locking safety covers that comply with ASTM F1346, and apartment complexes or any residential setting other than a single-family home. The second item is the one that matters for a spa at a house. Our safety cover guide covers what the cover's label must say and how the exemption is documented.
What the exemption does:
At a building permit. A hot tub or spa with a locking safety cover that complies with ASTM F1346 is outside the article, so the two-feature requirement in HSC §115922 does not apply to it. The building department that issues the permit reads the exemption for its own jurisdiction; HSC §115927 preserves local authority.
At a property transfer. BPC §7195 is in a different code and is not touched by the HSC exemption. The home inspection report still identifies which of the seven HSC §115922(a) features the spa has. A locking cover that complies with ASTM F1346 is feature 3 on that list, so the inspector records it, its label and whether the lock engages.
What it does not do. The exemption names hot tubs and spas. A spa built into a pool shares the pool's water, and the pool is not exempt. The pool still needs two of the seven features at permit, and the report at sale covers the pool and the spa.
The exemption turns on the cover, not on the spa. A cover that does not lock, a cover without the ASTM F1346 label, or a lock that no longer engages means the spa is an ordinary pool under the article. An inspector therefore photographs the label and tests the lock rather than taking the exemption as read.
The cover is a checklist item, not a footnote. PoolVerify's California template lists the approved safety cover as one of the HSC §115922 feature rows, with condition, notes and up to 10 photos on the row, so the label and the lock are in the report. See the checklist.
What the report must say about a spa
BPC §7195(a)(2) describes the inspection: at a transfer of real property with a pool or spa, an appropriate inspection includes a noninvasive physical examination of the pool or spa and the dwelling to identify which, if any, of the seven HSC §115922(a) features the spa is equipped with, and whether each is in good repair, operable as designed and, where applicable, appropriately labeled. The inspector is not required to determine whether a feature meets the ASTM or ASME specification.
BPC §7195(c) then sets the report contents:
Which, if any, of the seven features the spa has.
A specific statement if the spa has fewer than two of them.
Whether each feature present is in place, in good repair, operable as designed and, if applicable, appropriately labeled.
A written statement that a pool isolation fence meeting HSC §115923 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 Policy Statement "Prevention of Drowning" (2019).
"Transfer" under §7195(e) means a sale, exchange, installment land sales contract, lease with an option to purchase, other option to purchase, or ground lease coupled with improvements, of one to four dwelling units. The full report duty, including what "noninvasive" leaves out, is in our BPC §7195 home inspection guide.

The seven features when the water is a spa
The list is the same as for a pool; the HSC §115922 guide sets out each feature in full. What changes at a spa is where the inspector looks.
The seven drowning prevention safety features listed in HSC §115922(a).
HSC §115922(a) feature
What the inspector looks at on a spa
1. Enclosure meeting HSC §115923
A fence around a raised spa or deck: at least 60 inches high, gate opens away from the water, self-closing, self-latching with the latch at least 60 inches above the ground, no gap passing a 4-inch sphere, no more than 2 inches at the bottom
2. Removable mesh fencing meeting ASTM F2286
Gate self-closing, self-latching and able to take a key-lockable device
3. Safety pool cover with a label verifying ASTM F1346-23
The label, the lock and the cover's condition; this is also the HSC §115925(b) exemption feature
4. Exit alarms on the home's doors and windows with direct access
Sliding doors and windows onto the deck the spa sits on; the alarm sounds a continuous alarm or repeating verbal warning when the door or window is opened or left ajar
5. Self-closing, self-latching device on the home's doors with direct access
Release mechanism no lower than 54 inches above the floor
6. Pool alarm certified to ASTM F2208
Placed in the spa and sounding on entry into the water; a wearable alarm on a child does not qualify
7. Other means of protection
Independently verified by an approved testing laboratory to an ASTM, ASME or other nationally recognized standard, with a label
One line of the statute matters more at a spa than at a pool. HSC §115922(b) says the two-feature requirement is not satisfied by a safety pool cover together with a pool alarm. A spa owner who relies on the cover cannot add a floating alarm as the second feature; the second feature has to be an enclosure, mesh fencing, exit alarms, door devices or an approved other means. Nor does an exit alarm plus a self-closing door device count as two, whether on the same door or on separate doors.
For a spa on a deck reached through a sliding door, the practical pairs are a locking ASTM F1346 cover with exit alarms on the doors and windows, or the cover with self-closing, self-latching devices on the doors. The gate and latch numbers for a fenced spa are in the pool gate latch guide.
Suction outlets on a spa
Drain covers are not one of the seven features, and HSC §115922 says nothing about them. Suction outlets are governed by two other sections of the article. HSC §115928 applies when a permit is issued for a new pool or spa: at least two suction outlets per pump, hydraulically balanced and at least 3 feet apart, or an alternative such as skimmers or perimeter overflow, with anti-entrapment grates per ANSI/APSP-16 that cannot be removed without tools. HSC §115928.5 applies at a remodel permit and requires existing suction outlets to be upgraded to ANSI/APSP-16 grates.
Spas carry a larger share of entrapment incidents than their numbers suggest. The CPSC's May 2019 report on circulation and suction entrapment incidents from 2014 to 2018 counted 11 victims, all under 15; 7 of the 11 incidents were in spas, and both deaths were in spas. In a spa inspection the inspector photographs each suction outlet cover, notes whether it is intact and fixed with fasteners that need a tool, and counts the outlets per pump. The entrapment types and the emergency response are in our suction entrapment guide; the federal rule for public pools is in the Virginia Graeme Baker Act guide.
Equipment and electrical observations at a spa
The seven features and the suction outlets are the statutory part of a spa inspection. The rest is a condition record. PoolVerify's California template carries the same additional categories for a spa as for a pool: pool equipment (pump, filter, heater, chlorinator, automation system), electrical (GFCI protection, bonding, lighting, timer, wiring condition), plumbing (visible leaks, valves, returns, skimmer, main drain) and structure (deck and coping, tile, plaster, steps and ladder, drains).
Because a BPC §7195 inspection is noninvasive, these are observations, not tests: the pump and jets run, the heater fires when called, the control panel responds, the GFCI trips on its test button, visible bonding is connected, there are no visible leaks at unions and valves, and the shell, steps and deck are intact. A gas or electrical concern is written as an observation with a recommendation for a licensed contractor, not as a code determination. The report keeps these items separate from the seven features so that the feature count in the compliance summary is not confused with equipment condition. The pool equipment inspection guide covers the equipment pad in more depth.
Portable spas and swim spas
A portable spa is named in HSC §115921, so nothing above changes because the unit can be moved. Most portable spas ship with a rigid cover; the exemption in HSC §115925(b) applies only if that cover locks and complies with ASTM F1346, which the inspector confirms from the label. Whether a portable spa installation needs a building permit is a question for the local building department, and HSC §115924 requires anyone contracting to build a spa or do permitted work on one to give the consumer notice of the article's requirements.
A swim spa holds water over 18 inches deep and is intended for swimming, so it is a pool under the definition. It is usually too large for a locking cover of the kind the exemption describes, so at a permit it needs two of the seven features like any other pool.
Limitations
This guide is general information about California law, not legal advice; the current text of HSC §115921, HSC §115922, HSC §115925 and BPC §7195 on leginfo.legislature.ca.gov controls, and the building department that issues a permit may apply additional local requirements. Public spas and spas at apartment complexes are governed separately. PoolVerify is inspection software for California residential pool safety inspections; it does not perform inspections, certify inspectors, or issue compliance certificates.
Frequently asked questions
Do spas require the same safety inspections as swimming pools in California?
Yes. HSC §115921 defines a swimming pool as any structure for swimming or recreational bathing that holds water over 18 inches deep, and names hot tubs, spas and portable spas. The two-of-seven feature rule in HSC §115922 applies at a building permit, and BPC §7195 requires the home inspection report at a transfer to identify which features the spa has. HSC §115925(b) exempts a spa with a locking safety cover that complies with ASTM F1346.
Is a hot tub with a locking cover exempt from California pool safety law?
Yes, from the Swimming Pool Safety Act. HSC §115925(b) says the article does not apply to hot tubs or spas with locking safety covers that comply with ASTM F1346. The exemption depends on the cover, so an inspector records the cover's label and whether the lock works. BPC §7195 is a separate code and still asks the home inspection report at a transfer to identify which features the spa has.
Does a spa cover count as one of the seven safety features?
Yes. HSC §115922(a)(3) lists a manually operated or power-operated safety pool cover accompanied by a label verifying that it meets ASTM F1346-23. Two combinations do not count as two features under HSC §115922(b): a safety cover with a pool alarm, and an exit alarm with a self-closing door device on the same door or on separate doors.
Do I need a fence around a hot tub in California?
Not necessarily. An enclosure meeting HSC §115923 is one of the seven features, and a new or remodeled spa at a single-family home needs two of the seven when the permit is issued. A spa with a locking safety cover complying with ASTM F1346 is exempt from the article under HSC §115925(b). Where a fence is used, the gate latch sits at least 60 inches above the ground.
What qualifications do I need to perform spa inspections in California?
None set by the state. California has no home inspector license and no pool inspector license, and BPC §7195(d) defines a home inspector as any individual who performs a home inspection. BPC §7196 holds the inspector to the duty of care of a reasonably prudent home inspector, and BPC §7197 lists the unfair practices, including repairing an inspected property within 12 months. CREIA and InterNACHI are voluntary associations.
Are hot tub drain covers one of the seven safety features?
No. HSC §115922 lists drowning prevention features and does not cover drains. Suction outlets are governed by HSC §115928 at a new pool or spa permit and HSC §115928.5 at a remodel permit, which require anti-entrapment grates per ANSI/APSP-16. The CPSC's 2019 report counted 11 entrapment incidents from 2014 to 2018, 7 of them in spas, and both deaths were in spas.
Conclusion
A spa inspection in California is a pool inspection with two extra questions. Does the spa have a locking safety cover that complies with ASTM F1346, which takes it outside the Swimming Pool Safety Act under HSC §115925(b)? And if the cover is the first feature, is the second one something other than a pool alarm, since HSC §115922(b) does not count that pair? The report at a sale identifies the features either way, states if there are fewer than two, and records the condition of each.
