Tinley Park, IL Swimming Pools & Spas: Hot Tub Rules (2026)

Tinley Park requires a building permit for hot tub and spa installation when the unit holds 24 inches or more of water. Electrical work must comply with NEC Article 680 including GFCI protection on the dedicated circuit and proper bonding of the spa shell and equipment. A licensed electrician must install the dedicated circuit. Permanently installed spas typically require a 240V dedicated circuit; portable plug-in spas on 120V circuits also require GFCI protection. Setbacks from property lines must be met (generally 5 feet from side and rear lot lines in most residential zones). Spas are not permitted in front yards. A safety cover meeting ASTM F1346 (rigid enough to walk on and lockable) exempts the spa from pool barrier requirements; without such a cover, the spa must be enclosed by a 48-inch barrier like a pool. Noise from spa equipment must not exceed Village nuisance noise standards. Steam escaping from hot tubs toward neighbor properties should be considered in siting. Draining used spa water should follow MWRD guidance; chlorinated water should be dechlorinated before discharge to prevent damage to soil and storm drainage.
