William S. Sweatt House (4587 Mulberry Street) - This 2 1/2 story Queen Anne Victorian home is located on the corner of Prospect Avenue and Mulberry Street and has two major entrances; one facing each street. Designed by A.W. Boggs and built by Henry A. Westbrook, it is the last remaining example of their collaberation. It was built for for William S. Sweatt and his wife Nettie in 1891. Mr. Sweatt owned the largest furniture store in Riverside during the late 1880s and 1890s, and was also director of the Orange Growers Bank. It is considered eligible for the National Register under criteria A and B.
If you’re looking for a Victorian house in Riverside, this is the time to buy. The city has two to sell. The historic houses are the 1892 McIntyre house (pictured in the comments below) and 1891 Sweatt house. The city had planned to move the houses to a parcel at Fairmount Boulevard and Third Street, rehab them and sell them to buyers who would promise to live in them. The projected cost was going to be covered by redevelopment funds. That option disappeared after redevelopment agencies were ended by state legislation and the court ruling that upheld it.
