Rialto FAQ
Do I need a permit for a portable spa or hot tub in Rialto?
Yes. Even self-contained spas require an electrical permit (and usually a building permit) under Title 15 RMC and the California Electrical Code adopted by reference.
Does SB 442 apply to my existing pool?
Only if you remodel for $1,500 or more, or build new. Existing pools predating Jan 1, 2018 are grandfathered until a qualifying remodel.
San Bernardino FAQ
Do I need a permit for a portable pool in San Bernardino?
If the pool holds water more than 18 inches deep you need a building permit under Title 15 and CBC Appendix V. Small wading pools below that depth are generally exempt but still must comply with nuisance and drainage rules.
Can I pour my own pool without a contractor?
Owner-builder projects are allowed, but you must still obtain all required permits and pass every inspection. Most homeowners hire a licensed C-53 swimming pool contractor because of the engineering and electrical complexity.
