One unit includes a reception/office area with a private restroom and an attached bay, while the two additional spaces are set up as warehouse areas, each with its own restroom. The building is described as suitable for uses such as a contractor’s operation with storage and yard needs or an auto repair setup.

Located at 80 Barham Avenue in Santa Rosa, California, the site includes a lot size of approximately one third of an acre. A private well is included with the property, which can be a practical facility feature for certain on-site operations. The overall layout supports having multiple working areas under one roof.

For buyers seeking flexible space that can be operated by a single business across multiple bays and rooms, this arrangement offers practical separation between office and warehouse components. The mix of reception/office and warehouse areas with restrooms can support contractor logistics, light industrial storage, or auto-related repair use, depending on the tenant’s operating needs. The property is offered for sale.
