EV charger installations in Dane County are governed by the Wisconsin DSPS Uniform Dwelling Code (UDC) and state electrical code SPS 316 based on NEC Article 625. Madison, Fitchburg, and Middleton all issue expedited electrical permits. Wisconsin 2023 Act 121 clarifies that private EV charging is not a regulated utility.
Wisconsin regulates EV charging installations primarily through DSPS-administered electrical code SPS 316 (adopting NEC 2020/2023 Article 625) and the UDC (Wis. Admin. Code SPS 320-325) for one- and two-family dwellings. Residential Level 2 (240V) charger installation in Madison requires an electrical permit from Building Inspection (MGO §29.07) with typical fees of $60 to $120. Fitchburg, Middleton, Verona, Sun Prairie, and Stoughton require the same under their adopted UDC. 2023 Wisconsin Act 121 (effective March 2024) declares that owners of EV charging stations are not public utilities and may charge by the kilowatt-hour, removing prior regulatory barriers. New commercial construction in Madison requires EV-capable parking spaces under the Sustainable Madison Sustainability Plan and MGO §28.141 for certain large developments. The Wisconsin Condominium Ownership Act Wis. Stat. §703.165 protects unit owner EV installation rights in condos. A GFCI-protected 240V circuit, proper load calculation, and disconnecting means are required under NEC 625.
Unpermitted EV circuit work may trigger stop-work orders from Madison Building Inspection with re-inspection fees (MGO §29.07) typically $100 to $500. Non-compliant installations must be remedied before power-up. Condo boards blocking lawful installations violate Wis. Stat. §703.165 and face injunctive relief.
