3130-3132 San Bruno Ave, San Francisco, CA 94134

The property at 3130-3132 San Bruno Ave is a two-story, two-unit multi-family residential building located in the Portola neighborhood, owned by Lin Wan Quan & Chen Yueling. The building has an extensive renovation history spanning over two decades, with significant work occurring between 2013-2019. The most notable series of events began in 2016 when a complaint was filed alleging unauthorized construction work beyond the scope of permitted plans, specifically regarding a rear structure that had been reportedly modified from a single-story to a two-story building with multiple residential units, new windows, and stucco replacement. This complaint led to multiple subsequent permit applications (2019) to address the situation and legalize the existing rear building modifications, culminating in a director hearing in February 2019.

The building underwent substantial permitted improvements between 2013-2018, including a 408 sq. ft. horizontal addition to the second floor of unit 3132 San Bruno Avenue, which included a master suite and expanded family room ($75,000). This work was accompanied by new plumbing and electrical installations for an addition featuring one bedroom, one bathroom, and a laundry room. Earlier repairs in 2002 addressed various issues including dry rot, window replacements, and reroofing, while a conversion from overhead to underground electrical service was completed in 2004.

More recent concerns have emerged, particularly a series of 311 calls from late 2024 through early 2025, including multiple reports of garbage and debris, though these primarily relate to street cleaning issues rather than building safety. A sanitation issue involving a sewage back-up discharge from a side sewer vent was reported and resolved in December 2024. Additionally, there is currently an open issue regarding a sidewalk defect caused by tree roots, reported in December 2024. The building's history reveals a pattern of addressing both permitted and unpermitted work through subsequent permit applications and inspections, particularly in response to building violations. The most recent permit activity suggests ongoing efforts to bring all building modifications into compliance with current codes and regulations.
