House painting in Elm Grove.

The Census Bureau’s American Community Survey (2020–2024) puts the median year built for housing in the Village of Elm Grove at 1962 (margin ±3 years). The 1950s were the biggest building decade, with 26.5% of the village’s 2,446 housing units; the 1960s add 17.6% and the 1970s 18.2%, so 62.3% date from 1950 through 1979. Another 12.1% were built in 1939 or earlier, and only 11.2% in 1990 or later.

Those decades follow the village’s history. The Encyclopedia of Milwaukee’s entry on the village dates the first twenty residential lots to 1869, and the village’s 2007 comprehensive plan places them in the triangle between Watertown Plank Road and Juneau Boulevard. The encyclopedia describes commuters to Milwaukee arriving in the 1920s and 1930s and rapid suburban growth after World War II, and the plan dates the Brinsmere Manor and Indian Hills subdivisions to the 1930s. Elm Grove was part of the Town of Brookfield until it incorporated in 1955, and by 1960 it had just under five thousand residents.

It is a village of owned, detached houses. Single-family detached homes make up 76.2% of units, and owners live in 88.5% of occupied homes. About one unit in five (19.9%) is in a building of three or more units; if yours is a condominium, check the association documents before you plan exterior work or pick a color.

Age also decides whether Wisconsin’s lead-safe rule applies, and in Elm Grove it often will. The Census counts homes by decade, so the share built before 1978 can only be bracketed: between 65.9% (built before 1970) and 84.7% (built before 1980) of the village’s owner-occupied homes.

Elm Grove gives one body a say over the look of exterior work.

Paint is part of upkeep in the village code. The Elm Grove Property Maintenance Code, chapter 220, requires exteriors to be “maintained by painting or otherwise protected to prevent deterioration or a blighting influence upon neighboring properties” (§220-13B), and stairs and porches to be kept in good repair (§220-13C). It defines deterioration to include breaks, holes, rot, cracking, peeling, rusting and inadequate paint (§220-5). The chapter applies to every building in the village, whenever and however it was built (§220-3), and the Building Inspector and the Zoning Administrator enforce it (§220-6).

On a house that is fifty or sixty years old, paint usually gives out first where water sits: the bottom edges of siding and trim, window sills, porch floors and railings, and walls that stay damp. That is where most of the prep time goes. We scrape failing paint back to a sound edge, sand, spot-prime bare wood, and cut out caulk that has shrunk away from trim before any finish coat goes on.

The village enrolled in the Tree City USA program in 1990, and a 2006 inventory counted 8,245 trees along its streets, according to the 2007 comprehensive plan. The same plan describes Underwood Creek, a tributary of the Menomonee River, running through the village from its northern edge to the southeast corner at 124th Street and Bluemound Road, the floodway and floodplain fringe overlay districts that regulate land beside it, significant floods in 1997 and 1998, and a $12 million flood management project approved in 2005.

Shade and water change how a wall takes paint. A wall under trees or close to the creek dries slowly after rain and dew and is where mildew and algae grow first. We wash those walls with a mildew treatment and let them dry fully before primer goes on, and where gutters overflow or soil and mulch sit against siding, we point it out, because no paint outlasts a wall that stays wet. If you are planning an addition or other building work near the creek, ask the village about the floodplain rules first.

Elm Grove has no historic preservation commission. None appears among the boards in chapter 7 of the village code or on the village’s list of committees, commissions and boards, so it is the Building Board, not a preservation body, that reviews exterior changes. The 2007 comprehensive plan counted 108 Elm Grove records in the Wisconsin Historical Society’s Architecture and History Inventory, most of them from a systematic survey in 1992, and noted that an inventory record carries no regulatory or legal conditions.

The one Elm Grove listing on the National Register of Historic Places that we found is the Visitation Convent Complex at 13105 Watertown Plank Road, listed in 2011. The Wisconsin Historical Society’s register record traces the School Sisters of Notre Dame’s convent there to the 1850s and dates its contributing buildings from 1899 to 1958, among them the German Renaissance Revival Notre Dame Hall of 1899 and the Classical Revival Maria Hall of 1921. The National Park Service says National Register listing by itself places no restrictions on a non-federal owner unless the project receives federal assistance, usually funding or licensing and permitting.
