Lincoln FAQ
Is a plug-in portable hot tub exempt from permits?
Even cord-and-plug spas typically require an electrical permit for the dedicated GFCI circuit. Lincoln's $353 Detached Spa permit covers most residential installs - confirm with the Permit Center at 916-434-2470.
Do I need a fence around a covered hot tub?
If your spa has a listed, lockable safety cover meeting ASTM F1346 it counts as one of the two required Section 115922 features, so a separate barrier is not always needed - but the second feature still must be selected.
Rocklin FAQ
Does a portable plug-in spa need a permit in Rocklin?
The structural side typically does not require a building permit, but the electrical circuit (GFCI) and Article 680 bonding still must be inspected, and the spa needs either a locking ASTM cover or an enclosure.
What about a swim spa?
Swim spas usually exceed 18 inches and lack a locking cover during use, so they are regulated as swimming pools under §17.08.150 and the Swimming Pool Safety Act.
