3501-3505 Cabrillo St, San Francisco, CA 94121

The property at 3501-3505 Cabrillo Street is a two-unit, two-story multi-family residential building located in the Outer Richmond neighborhood, currently owned by Yu Family Trust and built in 1951. The building has undergone several significant improvements over its history, including a voluntary foundation bolting and plywood-to-stud upgrade in 1990, and two reroofing projects in 1995.

A notable regulatory event occurred in 1987 when there was an investigation into a potential illegal third unit that resulted in either the legalization of two family units or a reversion to the original configuration. Most concerning for current residents is a documented carbon monoxide incident (424) with no civilian injuries, though its date is not specified in the records. The most striking recent activity involves a pattern of parking-related issues, particularly between November 2024 and January 2025, with multiple reports of blocked driveways and sidewalk parking, though enforcement officers were often unable to locate the offending vehicles.

During this period alone, there were at least 10 separate parking enforcement incidents, with some cases being invalid due to incomplete reporting information. Additionally, there was one instance of garbage and debris (noted as glass) that required resolution in November 2024, and one high-priority sign-related issue that was addressed in December 2024. The building's permit history suggests regular maintenance and safety improvements, though the 1995 reroofing permits are now expired.
