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

Installing a hot tub or spa in Evanston requires a building permit from the Community Development Department at (847) 448-4311. An electrical permit is required for the dedicated 240-volt circuit and GFCI protection mandated by the National Electrical Code. Hot tubs must be placed on a structurally adequate surface and maintain zoning setbacks from property lines. A locking hard cover rated to ASTM F1346 standards is required when the hot tub is not in use. If the hot tub is located within a fenced pool area, it falls under the same barrier requirements as the pool. If located separately, barrier requirements apply if the unit is accessible to children and contains water deep enough to pose a drowning hazard. Drainage from the hot tub must not discharge onto neighboring properties or into the storm sewer system without approval. Indoor hot tub installations require adequate ventilation to prevent moisture damage and must meet all applicable building code requirements for indoor water features. Contact Code Enforcement at (847) 448-4311 for compliance questions.
