435-437 12th Ave, San Francisco, CA 94118

The two-unit residential building at 435-437 12th Avenue in San Francisco's Inner Richmond district is a 2-story flats and duplex structure built in 1925. The property, currently owned by Kenneth Wong, has undergone at least one significant maintenance operation in the past 15 years, specifically a roofing project completed in October 2007 at a cost of $8,000.

Recent incident records from 2023-2024 show several noteworthy events: there are currently two open cases involving the Fire Department (one general complaint from January 2024 and a support services request from January 2016), while a sewer service issue from December 2023 has been successfully addressed by PUC Sewer Operations. The building and its vicinity have experienced recurring graffiti problems over the years, with three documented incidents between 2014 and 2023, including particularly concerning cases of offensive graffiti.

The property has also seen occasional neighborhood issues such as sidewalk parking violations (July 2022) and illegal postings (August 2020), both of which were resolved through official intervention. A recent encampment situation was addressed and closed in September 2024. While the building's maintenance record shows attention to major systems like roofing, the environmental context suggests ongoing challenges with street-level disturbances and occasional infrastructure concerns that have required municipal intervention.
