Carson FAQ
Do I need a permit for an inflatable kiddie pool in Carson?
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.
How do I apply for a pool permit in Carson?
Apply through the Carson Civic Access self-service portal (cityofcarsonca-energovweb.tylerhost.net) or in person at Building & Safety. Plans must show the pool, barrier, equipment, electrical bonding, and a checklist of two SB 442 drowning-prevention features.
South Gate FAQ
Do I need a permit for a small inflatable kiddie pool?
No. California Residential Code §R105.1 and CBC §105.1 only require a permit for pools deeper than 24 inches. Portable inflatable pools under that depth do not require a building permit, though water-conservation rules under MWELO and any drought declarations still apply.
Does South Gate require a separate electrical permit for the pool pump?
Yes. Pool electrical bonding, GFCI protection, and pump/heater circuits fall under the California Electrical Code Article 680 and require a separate electrical sub-permit, typically pulled by the pool contractor or a licensed C-10 electrician.
