1845-1849 Mason St, San Francisco, CA 94133

The three-unit residential building at 1845-1849 Mason Street in Russian Hill is a three-story flats and duplex structure built in 1908, currently owned by Dea Wilbert & May Jung. The building's maintenance history shows consistent attention to the roof, with the most recent re-roofing project permitted in 2015 at a cost of $10,500, following an earlier re-roofing permit from 1992 that is now expired.

The property has undergone regular housing inspections by Housing Inspection Services in 1999, 2003, and 2006, all of which were resolved without any noted ongoing concerns. Of particular note is a recent and recurring issue with driveway access, though these incidents do not directly impact the building's internal conditions.

Between March and December 2024, there were nine documented cases of vehicles blocking the driveway, with some resulting in citations being issued (specifically in March and July 2024). While most of these incidents were resolved either through citations or officers being unable to locate the offending vehicles, they represent an ongoing external access challenge for the property. The building's documented history shows regular maintenance compliance and no recorded housing code violations or safety concerns through the most recent data available to October 2023.
