1842-1846 Mason St, San Francisco, CA 94133

1842-1846 Mason Street is a three-story, 6-unit multi-family residential building constructed in 1908 in San Francisco's North Beach neighborhood. The building has experienced several maintenance and safety concerns over the past twenty-five years, with the most significant recent issue being lead paint hazards in 2020-2021 that required remediation. These violations included peeling lead paint throughout the building, with specific notifications about proper containment and safety procedures for residents.

Other notable concerns included a sewer backup in March 2022, multiple reports of plumbing issues in the early 2000s (including bathroom leaks and repair needs), and various complaints regarding interior and exterior paint conditions. The building underwent some permitted improvements in 2011, including a kitchen remodel and electrical upgrades, though there was also an unpermitted renovation complaint in late 2010. Historical records show repeated attention to roofing issues, with permits for reroofing work issued in 1997.

The property has maintained routine inspection records, with regular follow-ups by housing inspection services, though some past violations related to lead paint, roof deck repairs, and other maintenance issues were officially abated by March 2021. Three-unit building violations from 2004 regarding stairs, exit obstruction, and basement storage access were also resolved. Temporary moving-related parking permits have been requested multiple times between 2013 and 2022, indicating typical residential turnover activity.
