1327-1329 12th Ave, San Francisco, CA 94122

The property at 1327-1329 12th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1905 and currently owned by the Cheng Family Trust. The building has undergone several significant maintenance and improvement projects, including a complete reroofing in 2019 costing $21,000, and a comprehensive remodel in 1987 that added bedrooms and bathrooms.

However, the property has experienced multiple compliance issues, particularly in 2016 when it faced violations related to lead paint hazards, interior surface maintenance, sanitation problems, and evidence of rodent infestation, with these violations being abated by March 2017. More concerning are the recurring complaints from 2018-2021 regarding potential illegal construction in the backyard, specifically relating to a shed structure that allegedly reappeared after being previously removed, with neighbors expressing concerns about fire hazards and rodent issues. In February 2018, multiple complaints were filed regarding possible illegal basement units with kitchens being rented out, though these complaints were subsequently marked as not active.

The building's maintenance history shows attention to basic upkeep, such as the 2019 reroofing project, but the property has attracted multiple neighborhood concerns over the years, including sanitation issues, structural compliance questions, and unauthorized modifications. Recent activity at the property has been limited to typical urban neighborhood issues such as garbage, sidewalk blocking, and abandoned vehicle complaints, none of which directly relate to the building's condition or safety. While some historical violations and complaints have been addressed, the pattern of recurring issues, particularly regarding unauthorized structures and potential illegal units, indicates ongoing challenges with building code and zoning compliance.
