House painting in Milwaukee.

Milwaukee’s housing is old by any measure. In the Census Bureau’s 2020–2024 American Community Survey, the median home in the city was built in 1953 (margin ±1 year). A third of all housing units (34.0%) date from 1939 or earlier, 63.9% from before 1960 and 84.2% from before 1980.

It is also a city of shared buildings. Single-family detached houses are 39.1% of housing units, while 21.5% of units are in two-unit buildings, the duplexes and two-flats found across the city. Owners live in 41.8% of occupied homes. If you own a two-unit building, tell us at the estimate whether both units are in scope and whether a tenant lives in either, so the schedule can be set with them in mind.

Age also decides whether Wisconsin’s lead-safe rules apply, and the survey does not split at 1978. The closest available figures are a range: between 83.4% (built before 1970) and 90.1% (built before 1980) of owner-occupied homes in the city.

Exterior work runs on a short season: at NOAA’s Mt Mary College station, the nearest climate-normals station to the city, the 1991–2020 median last spring freeze is April 26 and the median first fall freeze is October 18, and at Milwaukee Mitchell Airport, the lake-adjacent reference station, they are April 19 and October 29. Our guide on when to paint outside in Wisconsin sets those dates beside six other stations.

One house type is close to a Milwaukee signature. The Encyclopedia of Milwaukee’s entry on the Polish flat describes it as a small frame workers’ cottage that its owner raised on posts so a brick-walled lower unit could be built beneath it, turning one house into two homes. Chicago and other Midwestern cities call the same form a raised cottage. In Milwaukee the name attached to Polish neighborhoods, where the form spread between 1870 and 1920 as immigrant families needed affordable housing. As the form caught on, some were built as full two-story flats from the start.

For painting, that history means two different surfaces on one house: wood siding and trim above, masonry at the raised basement below. The city’s rehabilitation guide, As Good as New, notes that much of Milwaukee’s remaining cream brick is in the foundation walls of wood-frame houses, and that cleaning the visible courses of a tall raised basement can change how the whole building looks. Wood and brick are prepared and finished differently, so tell us at the estimate whether the brick on your house has ever been painted.

Milwaukee’s historic preservation ordinance dates from 1981 (Milwaukee Code of Ordinances s. 320-21). Once the Common Council designates a building, site or district, exterior changes need a Certificate of Appropriateness (COA) from the Historic Preservation Commission before work begins. The city’s COA page puts it broadly: all exterior repairs, replacements, alterations and building permits at a designated property need one, including jobs that need no building permit, such as re-roofing, re-siding, window replacement and tuck-pointing.

The city’s guide names the two most common causes of exterior paint failure: too much paint and too much moisture. After decades of coats, the paint gets too thick to move with the wood, cracks through to bare siding, lets water in and flakes off. Moisture comes in through leaking flashing, overflowing gutters, damaged shingles and missing trim, and from inside the house; the guide notes that homes heated with steam or hot water run more humid than homes with forced-air furnaces.

Its remedy is to fix the moisture first, then take loose paint back to bare wood in the problem areas, which usually does not mean stripping the whole house. It warns against two shortcuts for stripping paint from wood: high-pressure water blasting, which drives water deep into bare siding so the new paint peels as the wood dries, and sandblasting, which scars wood detail and raises the grain. Whoever you hire, ask how they will clean and strip your siding. Our exterior prep, step by step is on the exterior painting page. On a home built before 1978, scraping and sanding past the limits in the lead-safe rules on this page is regulated work.

Bay View, on the lakefront in the city’s southeastern section, began as a company town. In 1867 the Milwaukee Iron Company built a rolling mill there, with housing for the skilled workers it brought from Great Britain. Bay View became a village in 1879 and joined the City of Milwaukee in 1887, so the city’s permit and preservation rules apply there (the encyclopedia’s neighborhood entry).

In 1982 part of the original company town was listed as the Bay View National Historic District. The National Park Service says National Register listing by itself places no restrictions on what a private owner does with a property, unless the project involves federal funding or licensing. City review comes from city designation, and we found no city historic district in Bay View on the city’s list. Several Bay View buildings are individually designated, among them the Avalon Theater, the Beulah Brinton House, the Kneisler “White House” tavern and the Pryor Avenue Iron Well, and those need a COA for exterior work.

Researching the history of a Bay View house? The city’s preservation office publishes its 1990 Bay View survey and a Bay View walking-tour brochure on its publications page. Our Bay View page draws on both, along with the neighborhood’s Census tracts and its lake weather.

Outside the city limits, Milwaukee’s preservation ordinance and permit list do not apply; each city and village has its own code. We also work in Wauwatosa, which has its own Historic Preservation Commission and three city historic districts; our Wauwatosa page goes through them. In Shorewood, the Census puts the median home’s year built at 1939 or earlier, and 50.9% of housing units date from before 1940; a house there on the National Register needs a village permit for work the Building Inspector does not deem a minor repair (Shorewood’s rule for listed homes). Whitefish Bay’s median year built is 1944 (±3), with 92.0% of units built before 1980, and its Architectural Review Commission sees the permit applications for new buildings, additions and major exterior alterations (when Whitefish Bay’s Commission is involved). Greenfield is newer by comparison: median year built 1974 (±2), with 66.3% of units built before 1980, and fewer than half of its homes are detached houses; our Greenfield page covers its condominiums, its paint-upkeep code and its fence rules. Just north of the county line, the City of Mequon in Ozaukee County has an Architectural Board of its own and a list of 27 designated landmarks (Mequon’s review and landmark rules).

West Allis grew up around the Allis-Chalmers works: six in ten of its homes were built before 1960, and its property maintenance code prohibits chipping, flaking or peeling paint on any exterior surface (West Allis’s peeling-paint rule and rehab loans). Franklin, on the Racine County line, is newer: median year built 1990 (±2), and the old village of St. Martins has zoning districts of its own (Franklin’s St. Martins zoning and fence rules).
