421-423 Chestnut St, San Francisco, CA 94133

The property at 421-423 Chestnut Street is a three-story, two-unit multi-family residential building located in San Francisco's North Beach neighborhood, constructed in 1907 and currently owned by the Chew Family Living Trust. The building experienced significant maintenance and safety issues in 2022, which resulted in multiple violations and repair work. These included problems with windows, unsafe exterior stairs, electrical issues, plumbing concerns, and interior surface damages, as documented in complaints filed between July and October 2022.

The property was placed under a lead hazard warning in July 2022, leading to window replacement work to comply with regulations, as well as repairs to the rear stairwell for safety compliance, both completed in 2022 at costs of $15,000 and $5,000 respectively. Additional maintenance work included roof waterproofing completed in February 2022. The building underwent a tenant buyout in May 2023, with one tenant compensated $175,000.

Recent history shows ongoing community issues, including multiple parking enforcement actions between 2022 and 2024, noise complaints, and a sewer flooding incident in 2020. Several maintenance and safety violations documented in 2022 were abated by June 2023, including issues with mold/mildew, damaged walls and ceilings, and the need for various building safety improvements such as fire extinguishers and utility shutoff tools. The property has been subject to routine inspections, and while many violations have been addressed, some recent complaints indicate continued concerns, including an open excessive noise complaint filed in June 2024.
