Originally part of the Town of Brookfield, Elm Grove became a village in 1955. Elm Grove has the highest per capita income of any community in eastern Waukesha County. Not surprisingly, it has the highest home values in the area also. Elm Grove’s hallmark is spacious homes located on large lots. Because of its small size, most of Elm Grove was built up by the 1970’s. Often thought of as a barrier to through traffic, since no major street runs through the village, residents enjoy quiet neighborhoods with limited traffic as a result.
