Prefabricated hot tubs
Custom Inground hot tubs
In most states and cities, prefabricated above ground hot tub under a certain capacity and size do not require a building permit.
So, you likely won’t need a building permit if you are installing an average-size above ground (portable) hot tub.
This changes, though, if you are having a hot tub custom-built, or are installing an in-ground hot tub. In that case, you will need a building permit to proceed.
Even if you are planning to install a prefabricated above ground hot tub, you will still need to adhere to your local code enforcement offices for electrical codes.
For example: you need to have an electrician check your electrical sources to make sure there is no risk of electrical shock.
State Specific Requirements
In addition to general requirements, many states and even counties enact their own safety and permit requirements for hot tubs.
Here are some examples:
Of course, these permit requirements vary by location. So be sure to check with your local permit office before making any decisions or installing your hot tub.
