3550 San Bruno Ave, San Francisco, CA 94134

The property at 3550 San Bruno Avenue is a one-story, two-unit multi-family residential building located in Visitacion Valley, owned by Cheng Kai Hang & Lisa Y O C. Built in 1927, this flats and duplex structure has undergone minimal documented major maintenance, with only two significant permits on record: a reroofing project in 2007 costing $8,000, and an electrical upgrade to 175 amps in 2004 (though this permit has since expired).

The building has experienced several maintenance and safety concerns in recent months, particularly throughout 2024. There have been multiple reports of garbage and debris issues, with eight documented incidents between June and December 2024, all of which were resolved by Street and Environmental Services. Of particular concern is a rodent and insect infestation reported in February 2024, which was transferred to the Department of Public Health's Environmental Health division for investigation.

More recently, in August 2024, a sidewalk defect involving lifted pavement was reported, though this case was closed due to insufficient address information. The property has also experienced some issues with street signage, with two defacement incidents reported in June 2024—one of which remains open while the other was transferred to the Department of Public Works for resolution. While many of these issues have been addressed through existing city services, the frequency of recent sanitation-related complaints and the documented pest infestation suggest ongoing maintenance challenges in the immediate vicinity of the building.
