4420 California St, San Francisco, CA 94118

The two-story, four-unit multi-family residential building at 4420 California Street, owned by William C Chan & Gayle Trus, was constructed in 1962 and has undergone limited documented maintenance over the years. The only recorded significant building improvement was a reroofing project conducted in 2000 with a value of $6,000.

The property has experienced two routine housing inspections by Housing Inspection Services, one in 2001 and another in 2008, with the latter revealing a fire safety violation regarding egress obstruction that was promptly resolved within two days of being reported. The building's location has been subject to various municipal maintenance issues in the surrounding area, particularly in 2024, with multiple reports of street cleaning needs, graffiti, and noise complaints.

There have been three documented fire incidents, though none resulted in civilian injuries: a cooking fire contained to a container, a false alarm, and a water-related issue. While the building itself has maintained basic compliance with housing codes, as evidenced by the resolution of the 2008 violation and the absence of recent building-specific complaints, the surrounding areas has experienced various municipal maintenance challenges that have required attention from different city agencies.
