Rental Weatherization Inspections


Wisconsin Rental Weatherization Program

Starting January 1, 1985, most residential properties in Wisconsin have had to meet minimum energy conservation standards at the time of ownership transfer. Private state-certified inspectors are hired by owners to check properties for compliance with the standards. The Register of Deeds in your county will not record the transfer of a property unless:

  • An inspector has certified the property; or
  • The buyer has filed a Stipulation to bring it up to Code within a year; or
  • The property or transfer is shown on the Real Estate Transfer Return to be excluded from the Code; or
  • The buyer has filed a Waiver with the Department of Commerce stating that the building will be demolished within two years.

The Weatherization Standards

The following weatherization standards are code requirements:

  • WINDOWS must be double-glazed or equipped with storm windows. Exempted are windows in doors and furnace rooms. Windows located in basements, which are not habitable rooms may be permanently sealed and insulated to R-5 in lieu of double-glazing or installing storm windows.
  • PATIO DOORS AND INWARD-SWINGING EXTERIOR DOORS must be insulated and double-glazed; or be equipped with a storm door, unless they are provided with a vestibule. Storm doors must have self-closing devices.
  • WEATHERSTRIPPING must be installed on exterior storm doors.
  • CAULKING or glazing compound must be applied to exterior joints of storm doors and to glazing of storm windows. The Department will accept blower door testing of the building, per Comm 67.11(3), in lieu of the prescriptive infiltration measures.
  • MOISTURE CONTROL – Ventilation must be installed in attics and crawl spaces at a rate of 1 sq. ft. of free area of ventilation per 300 sq. ft. of floor area. A vapor barrier must cover the ground in crawl spaces.
  • INSULATION must be installed in "accessible" areas to the levels shown in the Code (see the following condensed table). "Accessible" means the space can be reached without removal or alteration of any finish materials of the permanent structure. For example, enclosed wall cavities are considered inaccessible and do not require insulation. However, an unfinished attic with floorboards must be insulated under the boards, if not insulated on top.
