Clarksville, TN Swimming Pools & Spas: Fencing & Safety Requirements (2026)

The Building and Codes Department lists spas and hot tubs in permanent installations among the structures requiring a pool permit, alongside in-ground pools, above-ground pools and associated decks. The zoning ordinance defines a swimming pool as a structure above or below grade designed to hold water for recreational use, which pulls spas into setback and building permit rules. A private residential or therapeutic tub is outside state jurisdiction. Once a hot tub serves an apartment building, condominium, homeowners association, subdivision or health club, Tennessee Department of Health rules classify it as a Type D public swimming pool, requiring a permit through the local health department, approved plans, and a four-foot enclosing barrier with self-closing, self-latching gates.
