3334 San Bruno Ave, San Francisco, CA 94134

The 9-unit, 3-story multi-family residential building at 3334 San Bruno Ave in Visitacion Valley, owned by Chen Cai Jin & Zhao Christi, has undergone several significant improvements and faced multiple compliance challenges since its construction in 1965. Most notably, the building completed mandatory soft-story seismic retrofitting in 2019-2022 (Tier 3) with a $80,000 retrofit that included adding steel moment frames, despite recent complaints in October 2023 regarding potentially incomplete work and exposed metal creating safety concerns. The building underwent substantial exterior maintenance, including multiple siding replacement projects between 2021-2022, converting to Hardi plank siding at a cost of $8,000.

A controversial attempt to add three ADUs in the rear of the first-floor garage was filed in 2021 but appears to have faced legal scrutiny, with complaints dating back to 2020 about unauthorized construction. The property has a history of addressing critical maintenance issues, including a significant bathroom and kitchen remodel in Apartment #3 in 2019, restoration of unit #7 under Ordinance 43-14 for in-law legalization, and various fire safety compliance measures. Multiple building violations were recorded in 2014-2018 related to fire safety, including issues with fire escape maintenance, smoke enclosure doors, and heat supply to occupied rooms, all of which were eventually abated.

Recent tenant buyouts in 2019-2020 indicate some turnover, with one unit receiving $45,000 in compensation. The property has also faced various maintenance challenges as evidenced by 311 calls and complaints, including plumbing issues reported in early 2022 and multiple reports of construction work occurring without proper permits in 2022 that attracted neighborhood complaints about early morning construction disrupting residents. The building's exterior and surrounding area have been the subject of periodic sanitation concerns, as reflected in multiple 311 calls regarding garbage and debris between 2024-2025.
