Altadena FAQ
Do I need a permit to build a pool in Altadena?
Yes — building, plumbing, and electrical permits are all required from LA County Building & Safety under Titles 26–30.
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.
