Hot Tubs

In most cases, a hot tub installation does not require a plumbing permit because there are no direct connections to the plumbing system. If you have a hot tub that has a direct plumbing connection, a plumbing permit is required.

A mechanical and electrical permit is required for a hot tub installation using gas heating. An electrical permit is required for a hot tub installation using electric heating.

If your hot tub will be placed on an elevated deck that is more than 30 inches above grade, there may be requirements related to the structural design of the deck. Please contact Development Services Center staff for more information if this situation pertains to the placement of your hot tub.

Any hot tub is required to have either a sandfiltration system or cartridge filter system. The backwash from a sandfiltration system will need to discharge to either the public sewer or to an on-site system approved by BDS, separate from the drainfield. If you have questions about filtration for your hot tub, please contact Environmental Soils at (503) 823-6892.
