Quick Answer
Tennessee does not have one statewide pool-permit process, every county and many cities run their own building and codes office, so the paperwork differs even between counties 40 minutes apart. State-level rules apply everywhere though: a permit is required for any pool, spa, or hot tub holding more than 24 inches of water, a functioning pool alarm must be installed before a permit is issued, and a safety barrier, generally at least 48 inches high with self-closing, self-latching gates, is required before the pool can be filled.
- Knox County: Knox County Codes Administration (865-215-2325), barrier at least 48 inches, gates self-closing and self-latching opening outward, latch at least 54 inches up.
- Loudon County requires a barrier at least 5 feet high, taller than the typical 48-inch minimum most other counties in the region follow.
- Roane County, Morales Outdoor Living's home base, defines a pool as holding more than 1.5 feet of water, the Roane County Building Department is in Kingston (865-717-0695), or the City of Kingston Codes Enforcement (865-376-0777) may apply inside city limits.
- Cumberland County requires county health department plan approval for any neighborhood or HOA pool serving more than 20 homes, and Blount County requires a separate permit for gas pool heat.
Does every pool need a permit in East Tennessee?
Essentially yes. State law requires a permit for any pool, spa, or hot tub with more than 24 inches of water, plus a functioning pool alarm and a code-compliant safety barrier before it is filled.
Who handles the permit if I build with Morales Outdoor Living?
We do, across every county we serve. We pull the permits, design the barrier to meet local code, and schedule the inspections.
Pool Permit Rules Change at Every County Line
Tennessee does not have one single pool-permit process. Each county (and many cities) runs its own building and codes office, adopts its own edition of the building code, and sets its own fees and inspections. That is why a pool in Maryville, a pool in Sevierville, and a pool in Kingston all follow slightly different paperwork even though they are 40 minutes apart.
Here is a plain-English, county-by-county guide for the areas we serve. When you build with Morales Outdoor Living, we pull the permit and manage the inspections for you, but it helps to know the rules going in.
This is a general guide, not legal advice. Codes change, and city limits often have their own rules separate from the county. Always confirm current requirements with the office listed for your area before construction.
The Rules That Apply Everywhere in Tennessee
A few things are set at the state level and apply across every county and city:
- A permit is required for any swimming pool, spa, or hot tub holding more than 24 inches of water. That covers essentially every inground pool.
- Tennessee's residential pool-alarm law: a city or county cannot issue a permit for the construction or substantial alteration of a residential pool unless the project includes a functioning pool alarm installed before the work is finished.
- A safety barrier is required before the pool can be filled. Most East TN jurisdictions follow the International Residential Code / International Swimming Pool and Spa Code standard: a barrier generally at least 48 inches high, with self-closing, self-latching gates that open away from the pool, a high latch, and no gaps a 4-inch sphere can pass through. (Some areas set their own height, see Loudon below.)
- Electrical work is governed by the National Electric Code (Article 680 for pools) and is part of the permit/inspection.

Knox County (Knoxville, Farragut, Hardin Valley, Bearden, Rocky Hill)
Permit required for pools over 24 inches of water. Barrier at least 48 inches, gates self-closing and self-latching opening outward, latch at least 54 inches up. See our deep dive: Knox County pool permits, fences & safety rules. Codes Administration: 865-215-2325.
Blount County (Maryville, Alcoa, Louisville, Walland, Townsend)
Blount County adopted the 2012 International Building and Fire Codes. Pools require a footing/site inspection and a final inspection, and gas heat (natural gas or propane) requires a separate permit. Decks, patios, and structures under 30 inches in height are exempt from setback and building-permit requirements. Development Services: 865-681-9301.
Loudon County (Lenoir City, Loudon, Tellico Village)
Residential permits are completed in office with a site plan, construction cost, and contractor license. Loudon's zoning resolution requires the pool area to be walled or fenced with a locked gate, no less than five feet in height, taller than the typical 48-inch minimum, so worth planning for. Planning & Codes Enforcement handles permitting.
Roane County (Kingston, our home base, Harriman, Rockwood)
Roane County defines an outdoor pool as one capable of holding water more than 1.5 feet deep. The Roane County Building Department is in Kingston (308 North 3rd St) at 865-717-0695. Inside Kingston city limits, the City of Kingston Codes Enforcement (865-376-0777) may handle your permit, we confirm which applies for your lot.
Sevier County (Sevierville, Pigeon Forge, Gatlinburg, Seymour)
Sevier County requires permits for both in-ground and above-ground pools and has adopted the 2018 International Swimming Pool and Spa Code. The Building Inspections Department oversees permitting and inspections. Cities like Pigeon Forge and Sevierville may have their own code office for in-city projects.
Anderson County (Oak Ridge, Clinton)
Prefabricated pools under 24 inches deep are exempt; anything deeper needs a permit. Anderson County follows the 2012 IBC (§3109 pool enclosures), 2012 IRC Chapter 42, and NEC Article 680. The barrier must be in place before the pool is filled, openings cannot pass a 4-inch sphere, and gates must be self-closing and self-latching. Building & Codes (Clinton): 865-457-6244. Oak Ridge, as an incorporated city, may have additional ordinances.
Cumberland County (Crossville, Fairfield Glade)
Cumberland County uses the 2018 IRC/IBC, and the City of Crossville has a dedicated Swimming Pool and Spa Code chapter. Note: neighborhood/HOA pools serving more than 20 homes require plan approval from the county health department. Codes Department: 931-710-5727.
What This Means for You
The takeaways are simple: nearly every real pool needs a permit, you'll need a code-compliant safety barrier and a pool alarm, and the exact process depends on which county (and whether you're inside city limits). It is exactly the kind of thing that trips up DIY projects and out-of-area builders.
We build across all of these counties, pull the permits, design the barrier to meet local code, and schedule the inspections, so you never have to decode a zoning resolution yourself.
