The Tumbleson House is an unoccupied historic house is between 1268 and 1528 square feet, and located next to, but separate from the county’s open space occupied caretaker’s residence. The circa 1890s stone building was most likely constructed by John Tumbleson, the original land patent holder for this part of the Hall Ranch Open Space property. The county purchased the property in 1994 and landmarked the building complex in 1998. The county completed a rehabilitation of the house in 2001. Prior to the rehabilitation project, asbestos testing was completed in 1999, but limited to the tile floor and their adhesive. As a result of the positive test results received from Analytica Solutions for the tile floor samples, the county contracted with Misers Asbestos Removal to remove the asbestos containing floor materials in June 1999.  In 2018, the county contracted with Heron Enterprises, USA to provide asbestos consultation services and develop a detailed asbestos abatement work plan. Oak Environmental completed the asbestos abatement following Herron’s work plan. Exterior lead paint test results did not return a hazardous lead reading.
