Twentieth Street Historic District

Twentieth Street Historic District is a collection of residential buildings in Craftsman and Prairie styles lining the 900 block in West Adams. The area contains houses from different building phases, each showing distinctive features from its era.

Developers began constructing the houses between 1900 and 1908, creating a residential neighborhood that grew in importance. The district gained recognition in 1991 when it was added to the National Register of Historic Places.

The street displays a blend of Prairie, Craftsman, and Victorian design elements that reflect local building traditions. Visitors can see today how different architectural approaches coexist harmoniously along the block.

The district sits about 0.75 mile (1.2 kilometers) north of the University of Southern California, positioned between Washington Boulevard and Toberman and Oak Streets. The area is easy to walk through and offers good views of the house facades from the street.

One residence stands out for its unusual Transitional Victorian architecture featuring an innovative overlapping board frame design. The building also displays a distinctive hip-roofed turret with tent-like configuration, making it a noteworthy architectural study.
