Hot tubs and spas in Dane County are regulated under Wis. Admin. Code SPS 390 (ISPSC) and state electrical code SPS 316. A 240V dedicated GFCI circuit requires an electrical permit in Madison (MGO §29.07). Locking safety covers meeting ASTM F1346 can satisfy the UDC barrier requirement.
Wisconsin regulates residential spas and hot tubs under Wis. Admin. Code SPS 390 (adopting the International Swimming Pool and Spa Code) and SPS 320-325 (Uniform Dwelling Code). Electrical connections must comply with SPS 316 and NEC Article 680, requiring a dedicated 240V circuit with GFCI protection within sight of the spa. Madison Building Inspection (MGO §29.07), Fitchburg, Middleton, Verona, Sun Prairie, and Stoughton all require an electrical permit (typical fee $60 to $150). A plumbing permit may be required for direct drainage connection under SPS 382. Barrier requirements under ISPSC 305 apply unless the spa has a lockable safety cover meeting ASTM F1346 standard; the cover must be in place whenever the tub is not actively supervised. Setbacks from property lines match accessory-structure zoning: typically 5 feet side, 10 feet rear in Madison MGO Ch. 28. Decks supporting hot tubs must be designed for at least 100 psf live load, typically requiring engineering. Dane County Ch. 11 Shoreland Zoning imposes setback requirements within 75 feet of the ordinary high-water mark on Yahara lakes.
Unpermitted electrical work MGO §29.07: stop-work, double permit fees, forfeiture $100 to $500. Missing or non-compliant safety cover without barrier: immediate correction, use prohibited. Shoreland setback violations Dane County Ch. 11: daily fines and remediation.
