Hot tubs and spas in Carson are regulated identically to swimming pools under California Health and Safety Code § 115921, which defines a 'swimming pool' to include hot tubs and spas containing water over 18 inches deep. A building permit (plus electrical, and plumbing/gas if applicable) is required through Carson Building & Safety. The most common SB 442 compliance path for spas is a locking ASTM F1346 safety cover (HSC § 115922(a)(3)) plus a second feature such as a self-latching gate or door alarm.

Carson FAQ
Does my plug-in 110V hot tub need a permit in Carson?
Yes if the water depth exceeds 18 inches. HSC § 115921 includes hot tubs in the definition of 'swimming pool,' and the California Building Standards Code adopted by Carson's Building Code chapter requires a building and electrical permit regardless of whether the spa is 110V plug-in or 240V hardwired.
Is a locking cover alone enough to satisfy SB 442 for my spa?
No. An ASTM F1346 locking safety cover counts as one of the seven SB 442 features under HSC § 115922(a)(3), but the statute requires at least two features. A second feature — typically a self-closing/self-latching door device or enclosure — is also required.
Can I install a hot tub on my apartment patio?
Generally no without landlord consent and a permit. Multi-family installations also raise HSC §§ 115921–115929 questions about whether the spa is treated as 'public' under § 115925, which has different (more stringent) commercial-pool requirements regulated by LA County Environmental Health.
