1851-1853 Mason St, San Francisco, CA 94133

The two-unit residential building at 1851-1853 Mason Street in Russian Hill, owned by Lena Cresci Revoc Trust, has a documented history dating back to its 1908 construction. The property has undergone several roof maintenance works, with the most recent reroofing project occurring in May 2021 at a cost of $12,500, following earlier efforts in 2004 ($10,000) and 1988, suggesting regular maintenance of this critical building component.

The building's recent history from 2015 onward shows two significant sewage backup incidents in March 2015 that required attention from PUC Sewer Operations, though these issues were ultimately resolved. The property has experienced ongoing challenges with parking enforcement, particularly regarding driveway access. There have been three documented cases of driveway blocking in 2023 alone, resulting in citations.

The building's immediate vicinity has also seen issues with abandoned vehicles in June 2015, with two separate incidents involving a Honda Accord and a Nissan truck, though both vehicles were gone upon inspection. In late 2019, there were requests related to curb painting and maintenance, including interactions with the MTA regarding a legitimate red zone establishment for the property. While the building's major systems have required attention over the years, the regular roofing maintenance suggests proactive care of the building's infrastructure.
