Flower Mound FAQ
Do I need a permit for a portable hot tub in Flower Mound?
Plug-in 120-volt portable hot tubs with integrated GFCI generally do not require a building permit, but they must still comply with barrier requirements if capable of holding water 18 inches or deeper. A lockable ASTM F1346 safety cover may serve as an alternative barrier.
Can I drain my hot tub into the street or storm drain?
No. Hot tub drainage must not discharge to stormwater systems or neighboring properties. Water should be directed to sanitary sewer connections or allowed to percolate on your own property away from neighboring lots.
Lewisville FAQ
Do I need a permit for a hot tub in Lewisville?
Yes. An electrical permit is required for hot tub installation. If the spa does not have a locking safety cover, a building permit for a barrier enclosure may also be required. Contact Inspections at (972) 219-3480.
Does my hot tub need a fence around it?
Only if it does not have a locking safety cover that meets ASTM F1346 standards and supports at least 50 pounds per square foot. A compliant locking cover exempts the spa from the separate 48-inch barrier requirement.
