1650-1656 Mason St, San Francisco, CA 94133

The two-story, four-unit multi-family residential building at 1650-1656 Mason Street in North Beach, owned by Hom/teshima Tr, was constructed in 1925 and has undergone several significant events throughout its history. The building experienced a noteworthy series of violations in November 2007, when multiple safety and maintenance issues were documented, including problems with walls/ceilings, water heater seismic bracing, door security, and various fire safety requirements such as fire extinguishers and utility shutoff tools. All these violations were officially abated by December 17, 2007.

More recent records show routine housing inspections in 1999, 2004, and 2011, suggesting regular oversight of building conditions. The property has undergone some structural maintenance work over the years, including a reroofing project completed in 1991 and a door replacement project in 1989. While there have been two fire-related incidents recorded—an accidental alarm activation and a gas leak—both occurred without civilian injuries. The building's location has experienced frequent parking enforcement issues, particularly in recent years, with numerous calls made between 2020 and 2025 regarding vehicles blocking driveways, parking on sidewalks, and other violations.

Most of these cases were either resolved through citations or resulted in officers being unable to locate the offending vehicles. The most recent activity at the address includes a 2025 encampment report (unable to locate) and a 2023 driveway blocking incident that resulted in a citation. While the building has a history of safety violations, it's noteworthy that all recorded violations were addressed within a reasonable time frame, and there have been no major documented safety incidents in recent years. The building's age and status as a multi-family residential structure suggest it has undergone typical urban maintenance and compliance processes over its nearly century-long existence.
