Fullerton FAQ
Do I need a permit for a hot tub in Fullerton?
Portable plug-in hot tubs generally do not require a building permit, but hardwired electrical connections require an electrical permit. Permanently installed spas with structural support, dedicated circuits, or gas connections need building permits. Contact the Building Division at (714) 738-6856.
Do I need a fence around my hot tub in Fullerton?
If the water depth exceeds 18 inches, a 60-inch barrier is required around the spa. However, an approved locking safety cover meeting ASTM F1346 standards may serve as an alternative to a full perimeter barrier for hot tubs and spas.
How close to my property line can I put a hot tub?
Spas must meet the zoning district's setback requirements. In R-1 zones, this is typically 5 feet from side and rear property lines. Equipment must also be positioned to minimize noise impacts on neighbors.
Midway City FAQ
Does a hot tub need a fence in unincorporated Orange County?
A spa or hot tub deeper than 18 inches is treated like a pool under the OC note sheet and the California Pool Safety Act, so the enclosure and secondary-barrier rules apply. However, a spa with an approved locking safety cover meeting ASTM F1346 can qualify as a drowning-prevention feature under state law (HSC 115925).
Do I need a permit for a spa heater?
Yes, spa heating equipment must be installed under permit and may be installed only if the manufacturer certifies the system per 2019 California Energy Code Section 110.4. A cover must be installed if the outdoor spa uses a heat pump or gas heater, and equipment noise must stay within OC Noise Ordinance Section 4-6-5 limits.
