The Otto & Inga Carlson House is located just north of the downtown Mount Vernon commercial district. The home, constructed circa 1915, is an intact example of the Craftsman Bungalow style, distinguished by its front-facing gable roof and smaller gable covered porch. It boasts all of the typical features of the style including exposed rafter tails, an open entry porch on the main facade, a use of local materials and an open interior.
