4095 Mission St, San Francisco, CA 94112

The 19-unit, 3-story multi-family residential building at 4095 Mission Street, constructed in 2011 and currently owned by 55 Trumbull Street LLC, has experienced several significant events related to safety systems and building maintenance over recent years. Most notably, there is currently an open violation regarding sleeping area requirements issued in November 2023, and a backflow preventer replacement and hydronic boiler inspection project from 2022 that has since expired.

The building's fire safety systems have required multiple attention points, with violations and corrective actions related to sprinkler/standpipe systems, exit maintenance, and extinguishers recorded between 2016 and 2023, though most were resolved promptly. A recent permit from June 2023 demonstrates ongoing maintenance of fire alarm systems, specifically adding a new heat detector and elevator recall system.

The property has experienced some operational issues, including a vacant commercial space complaint filed in June 2023, which remains active, and a similar vacant storefront complaint from 2019. Recent infrastructure concerns have been documented through multiple 311 calls from late 2024 to early 2025, primarily related to garbage and debris removal, with several cases involving street cleaning needs and pavement defects requiring attention. The building's recent activity shows continued attention to fire safety systems and infrastructure maintenance, though there are still open violations related to sleeping area requirements and parking sign maintenance as of late 2024.
