The Leanor is registered as a Historical Building in the National and State Registries

The building located at 2oo South Main is designed with Flemish/Common bond brick walls that have projecting brick sills and segmental arches. It has a corbelled and zipper brick cornice. The interior of the first floor has open chamfered wooden posts with wooden corbel capitals down the middle. The second floor has a full office across the front and a center hall that is flanked by four 1-room apartments on each side. Each pair of apartments has a connecting door.

The building's architectural features include metal grills over the unmodified second-story windows. The removable brick veneer is located above the transom. However, the stuccoed portion of the first floor is a more detrimental remodeling, although the original chamfered wood posts appear to remain in place.

The Leanor's building style, built in 1906, typifies the often-modest construction that accompanied the city's railroad boom. It is constructed of local brick, and its ornamentation is concentrated in its decorative brick-style cornices. Specifically, the building features a zipper brick and dentil cornice on the front and a corbelled cornice stepping down along the side.

This building is listed under the United States Department of the Interior National Park Service Inventory #711.
