3906 3rd St, San Francisco, CA 94124

The two-story multi-family residential building at 3906 3rd Street in Bayview, owned by Renato Guerrero, was built in 1913 and contains two units plus commercial space. The property has undergone various improvements and maintenance work over the years, with the most recent significant renovations occurring in 2011, including exterior facade work, new signage, and window restorations totaling approximately $17,000.

The building has experienced recurring fire safety system issues, with violations noted in 2024 for fire extinguishers and alarm systems, following a pattern of similar violations dating back to 2021, including sprinkler system concerns in 2022. While most historical building violations from 2008-2018 were addressed and abated, including broken windows and water conservation compliance issues, the property is currently facing multiple open issues as of January 2025, particularly regarding sidewalk conditions and encampment matters outside the building. The commercial portion of the building, previously known as "Taqueria La Laguna," has had several permitted improvements including fire suppression system installations and various electrical upgrades, though many permits from the 2000s are now expired.

Recent activity includes tenant buyouts recorded in October 2024, each valued at $16,500, suggesting significant changes to the residential component of the building. The property has experienced several fire system alarm activations over the years, primarily related to system malfunctions rather than actual fires, though there have been occasional incidents involving smoke and contained fires. A health and safety inspection in 2024 resulted in violation notices that have since been abated, though additional violations from 2023 regarding sprinkler and alarm system maintenance remain open at adjacent addresses.
