Sauna permits in Middleton, WI

Middleton is simple on paper: every accessory building needs a combined zoning and building permit, whatever its size. The complication is wood. Middleton's code bans outdoor solid-fuel heating devices, meaning any not inside a dwelling. Read literally, that could reach a wood-fired sauna stove, so confirm in writing before choosing wood.

Red flag: confirm in writing

Middleton §13.03 and §17.02(5)(b) treat "outdoor solid fuel" heating devices, meaning any not inside a dwelling, as banned or a nuisance. A sauna stove is inside a building, but not a dwelling. Until the city puts an interpretation in writing, an electric heater is the safer choice in Middleton.

Electric heaters avoid this question entirely. A Wingra or Monona with a 240V heater is permitted like any other accessory building.

Good to know in Middleton
  • Saunas over 70 sq ft go through plan review, which adds time. A Wingra-size sauna stays under it.
  • One combined $80 fee covers zoning and building.
  • Ask the building inspector about wood stoves before you order, not after.
