Carson FAQ

No. California HSC 115921 and the California Residential Code only regulate water containment structures over 18 inches deep. A small inflatable or kiddie pool below 18 inches does not trigger a building permit.
Do I need a separate electrical or plumbing permit?
Yes. Under the California Building Standards Code adopted by Carson's Building Code chapter, pool electrical bonding/grounding and gas/plumbing for heaters require separate trade permits in addition to the main pool building permit.
