489 Washington Avenue is a property that has worn many hats. Before it was a Pentecostal Church, this Second Empire mansion was a dance studio, a Grand Army Republic meeting hall, and a private family home to a descendant of the father of Irish Republicanism. With every new inhabitant, a piece of the building's architecture was changed.

Lascelles and Grace Maxwell, the original owners of the home, raised their seven children in this house. The Maxwell's children sold the house in 1904 after both of their parents had died. It was then acquired by the Grant Chapter of the Grand Army of the Republic in 1906. The old boy's club was a fraternal organization that supported veterans of the Union Army who fought in the Civil War. The ground floor was converted into a museum to display military memorabilia, which touted all sorts of firearms, uniforms, and possessions of Ulysses S. Grant, whom the chapter was named for. The second story had its walls removed to be converted into a large meeting room, where a variety of social events were held. The groups' membership had dwindled by the late 1920s, and the Hall was sold.

Weber Studio operated out of the space, teaching ballroom, Foxtrot, and the waltz led by A.J. Weber. The hall was still rented out for meetings and other events until 1940 when the property was sold to the Evergreen Church of God. The white stucco was removed and covered with a false brick facade, revealing the original brick in certain areas.
