House painting in Waukesha.

The Census Bureau’s American Community Survey (2020–2024) puts the median year built for housing in the City of Waukesha at 1979. In the city, 11.5% of homes were built in 1939 or earlier, 21.7% before 1960 and 51.2% before 1980. So roughly one Waukesha home in seven was built before 1950 and carries decades of old coats, while about one in six went up in the 1990s. Half of all units (50.6%) are single-family detached houses, and 58.8% of occupied homes are lived in by their owners.

A home’s age changes the job. On a house built before 1978, scraping and sanding old paint becomes regulated work once it passes the state’s size thresholds; the lead-safe rules are set out further down this page. The Census counts homes by decade, so the pre-1978 share can only be bracketed: between 37.7% (built before 1970) and 53.9% (built before 1980) of the city’s owner-occupied homes. On a newer house, the first questions are usually the siding material and how well the caulk has held, and we check both at the estimate.

These figures cover the City of Waukesha only. The Village of Waukesha is a separate municipality that the Census reports on its own. The city rules on this page apply only to addresses inside the city.

If your house is a city-designated landmark or stands in one of the city’s historic districts, Waukesha asks for a Certificate of Appropriateness from the Landmarks Commission before most exterior repair work or alterations begin. The Commission meets on the first Wednesday of each month, and applications are due two weeks before the meeting. Build that into the calendar when you book exterior work.

The city publishes a Design Policies Guide that explains which projects need review. We were not able to download it when we wrote this page (October 2026), so we can’t tell you whether repainting alone needs a certificate. Before exterior work on a designated property, ask the Planning Department. The city’s Landmarks page lists the staff contact and suggests talking an application through before you submit it.

The city lists nine historic districts, each with the year it was listed on the National Register of Historic Places: Block C Downtown (1995), Caples Park (1988), College Avenue (1982), East Broadway (1995), Five Points Downtown (1982), Laflin Avenue (1982), Madison Street (1990), McCall Street (expanded in 1993) and Wisconsin Avenue (1982). It also publishes a map of its designated landmarks and districts. If you aren’t sure about your address, the Planning Department can tell you.

National Register listing and city landmark status are two different things. The city notes that some properties have one and not the other. The National Park Service says that National Register listing by itself places no federal restrictions on a private owner; city and state rules still apply. In Waukesha, it is city designation that brings in the Landmarks Commission.

Pewaukee is two municipalities, the City of Pewaukee and the Village of Pewaukee. Each has its own government; the Village contracts with the City for building permits and inspections. The housing is also quite different. Check which one your address is in before you plan exterior work.

City of Pewaukee (American Community Survey 2020–2024): median year built 1993; 28.6% of homes built before 1980; 63.2% single-family detached; 83.2% owner-occupied. Between 20.7% and 33.8% of owner-occupied homes were built before 1978 (the Census bins stop at 1970 and 1980).

Village of Pewaukee: median year built 1985; 40.1% built before 1980; 38.7% single-family detached; 61.4% owner-occupied; 24.7% to 37.9% of owner-occupied homes built before 1978. With fewer than four in ten homes detached, many Village owners share walls or a building with neighbors. If yours is a condominium or townhouse, check whether exterior color and repainting are your decision or your association’s.

The Village has a Historic Preservation Commission. It designates historic landmarks, sites and districts and regulates the construction, reconstruction and alteration of designated sites. Its seven members meet as needed. In its 2024 minutes, the Commission reviewed an exterior lift addition at a church on West Wisconsin Avenue and approved a design whose materials and color match the existing building. We have not found a published list of the properties the Village has designated, so if your home might be one, ask the Village before exterior work.

Neither municipality’s permit page lists painting, and the Village asks residents to contact it before starting work to find out whether a permit is needed. Historic review, upkeep and zoning differ between the two, and our Pewaukee page sets out which rule belongs to which.

Brookfield: the City and the Town of Brookfield are separate municipalities, and we work in both. The City’s code sets rules for keeping painted surfaces up and for fence colors in some locations; our page on those paint and fence rules goes through them.
