In most areas prefabricated, above-ground swim spas and hot tubs under a certain capacity and size do not require a building permit as long as you follow zoning rules. If you’re having a swim spa custom-built or are installing it in-ground however, you will likely need local building, electricity and plumbing permits in order to proceed.

Is a Permit Required to Install a Swim Spa? 

Although building codes vary by state in the U.S, typically a building permit is only required for a swim spa or hot tub with a water capacity of more than 5,000 gallons which exempts most spas. Local zoning rules and Homeowners Association (HOA) guidelines can regulate the location of your swim spa, and may have their own safety and permit requirements such as: its distance from your property line, safety measures like a locking cover, draining restrictions, etc. 

If you’re considering building a deck or gazebo to house your swim spa outdoors, those additional structures will require building permits. You’ll also likely need electrical, plumbing and/or mechanical permits. Consider hiring an electrician and plumber to do the install due to safety concerns about electrical and plumbing hook-ups, and the required adherence to building codes. To ensure that your swim spa is fully compliant, be sure to check with your state, city and local ordinances like a HOA before installing your spa.

While the details may vary by location, the general permit path often looks like this:

1. Contact your local building department: They’ll guide you through the specific permit requirements for your area and provide the necessary application forms.
2. Hire a qualified contractor: For installations requiring permits, enlisting a licensed and insured professional ensures everything is done right and meets code.
3. Submit your permit applications: Be patient, permit processing times can vary.
4. Inspections: Once your permits are approved, expect inspections from building officials, electricians, and plumbers to ensure everything is shipshape.
5. Permit paradise: Upon passing all inspections, you’ll finally receive the green light to let the aquatic fun begin!

Swim spas are single-shell, molded acrylic models that arrive pre-plumbed and pre-wired, ready to install on any sound and level surface indoors or outdoors. All of the components are contained within the unit, and there’s no plumbing that exits the cabinet. Swim spas are also portable, and can be moved to a different location or new home. When you’re requesting permits, remember that a swim spa is basically a large hot tub, it’s not a pool, and its regulations will be the same as a hot tub. 

Swim Spa Installation Considerations

If you’re installing your spa outdoors, you’ll need to know the setback rule, the minimum distance that a building or structure must be set back from your property line. These rules vary based on where you live, and could be 5, 15 or even 25 feet from the property line. Typically if you are within the “safe zone,” the city cannot prevent you from installing a swim spa. Lot coverage is also an important zoning rule when planning your installation. It’s the percentage of your property that’s occupied by a building, driveway, garage, patio, gazebo, etc.

Once you’ve identified an area in compliance with ordinances, you’ll need to ensure there’s a strong, level surface for installation. Swim spas are heavy and require a concrete pad that’s at least 6″ thick or a deck that can support its weight. You’ll need a level surface to ensure that the internal systems can operate and drain correctly. It’s also critical to select a site where water will drain away from your electrical equipment compartment. Indoor considerations include adequate ceiling height, proper ventilation and drainage. 

Swim spas have unique electrical requirements and it’s your responsibility to ensure they’re up to code. Keep in mind most spa technicians have expertise in spa hardware and equipment, but not necessarily in plumbing and electrical systems. While it might be tempting to embark on a do-it-yourself installation, remember that a spa will require both water and electricity. For your safety and ease, we highly recommend hiring professional plumbers and electricians to do the job for you.
