Lakeville, MN Swimming Pools & Spas: Hot Tub Rules (2026)

Lakeville does not publish a separate hot tub or spa ordinance; spas are addressed through the city's pool barrier provisions (Section 11-21-5.G) and the Minnesota State Building and Electrical Codes that Lakeville enforces. The city's pool barrier rule applies to pools having a depth of 24 inches at any point and a surface area exceeding 150 square feet (about a 14-foot diameter). Many residential hot tubs and spas are smaller than 150 square feet of surface area, so they may fall below the city's pool-permit and pool-fence threshold; however, a spa that meets the depth and surface-area thresholds is treated like a pool and must be permitted and provided with an approved barrier. Regardless of size, electrical work for a hot tub or spa requires a separate electrical permit obtained from the City of Lakeville Inspections Department, and the installation must comply with the Minnesota State Building Code and the National/Minnesota Electrical Code (including required GFCI protection and bonding under the state-adopted code). Because spa coverage depends on dimensions and installation specifics, Lakeville directs residents to confirm permit and barrier requirements directly with the Building Inspection Department at 952-985-4440 before installing a hot tub or spa. This site does not assert a Lakeville-specific spa fence height because the city handout does not state one separately from the general pool barrier rule.
