The Near West Side became a Conservation District in 2019 but has been on the National Register of Historic Places since 1997. The conservation district features Bloomington's largest collection of vernacular buildings including the Gable Ell and Hall and Parlor forms.  

Many of these homes have had few modifications over the years so original details abound such as decorative rafter tails and attic vents, limestone foundations and retaining walls, and late 19th century windows, doors, and porches. The neighborhood has remained relatively intact for the past century and still conveys the distinct architectural character from their period of construction. 

City staff and district residents are currently working on the design guidelines.
