742-748 Filbert St, San Francisco, CA 94133

The four-unit multi-family residential building at 742-748 Filbert Street, located in San Francisco's North Beach neighborhood, is a two-story flats and duplex structure built in 1907 and currently owned by Lin Jim Hao Yuan. The property has undergone several significant maintenance and improvement works over its history, with the most recent being sewer-related issues in 2023, including a sewage backup from a vent in August 2023 and a sewage discharge incident in September 2024, both of which were resolved by PUC - Sewer Operations.

The building has a documented history of routine inspections by Housing Inspection Services, with multiple violations noted in 2004 that were all abated by November 2004, including issues with fire safety equipment, security features, and stair repairs. Earlier renovation work was performed in the early 1990s, including a major renovation in 1991-1992 involving wall and ceiling modifications and kitchen improvements in Unit #746. The building has received regular attention from city services, with documented 311 calls primarily related to sanitation issues in the surrounding area between 2019-2023, including reports of waste on sidewalks and general cleaning requests.

A notable incident occurred in 1997 involving unauthorized electrical meter connections between units 744 and 748, which took several years to resolve, finally closing in 2013 through the Electrical Inspection Division. While the building has had its share of maintenance and compliance issues over the years, most violations appear to have been addressed promptly, and recent complaints have primarily concerned external infrastructure rather than building-specific problems. The most recent building-specific works on record include a reroofing project from 2007, indicating some attention to major structural elements, though no recent major renovations or improvements have been documented.
