Cedar Park FAQ
Do I need a fence around my backyard hot tub in Cedar Park?
Not if the spa has a lockable, ASTM F1346-rated safety cover. With a compliant cover, the 2021 ISPSC adopted in Article 3.01 exempts spas from the 48-inch barrier rule. Without a cover, the spa must be enclosed like a pool.
Can I install a plug-in 110V hot tub without a permit?
A building permit is still required, but a portable cord-and-plug spa under 50 gallons may not need a separate electrical permit. Confirm with Cedar Park Development Services at 512-401-5100 before installing.
