358-360 12th Ave, San Francisco, CA 94118

The 3-unit multi-family residential building at 358-360 12th Avenue in the Inner Richmond, owned by Helen N Leong, was constructed in 1912 and is a 3-story flats and duplex structure. The building has experienced several significant maintenance and safety issues over the past two decades, most notably a series of problems in 2016-2018 involving water intrusion, mold, leaking ceilings, and maintenance concerns including front stair repairs and basement ceiling work. In July 2016, multiple violations were recorded that categorized the property as a "nuisance," with issues including weatherproofing problems, required building permits, plumbing violations, and a notable complaint about no heat, hazardous wiring, insect/rodent issues, and a gas leak.

Earlier violations from 2001 had addressed security, fire safety, and building maintenance issues including stair repairs and alarm system problems. Recent building permits show limited activity, with the most notable work being front stair repairs and basement ceiling repairs in 2016 costing $4,000. The property has experienced recurring issues with water and sewer systems, as evidenced by multiple 311 calls in 2020 regarding sewage backup and water concerns.

While there have been improvements made over the years, including the resolution of some violations and complaints, the building's history shows a pattern of maintenance challenges that have required intervention from housing inspection services. A cooking fire incident was recorded, though it was contained with no civilian injuries reported. The most recent confirmed building activity was a street space permit issued in February 2018.
