634-636 Funston Ave, San Francisco, CA 94118

This two-unit residential building, located at 634-636 Funston Avenue in San Francisco's Inner Richmond neighborhood, is a two-story flats and duplex structure built in 1920 and currently owned by Woo Davis Y. The building's maintenance history shows several significant structural improvements over the years, with foundation reinforcement carried out in 2007 through the installation of foundation bolts spaced at 4-foot intervals, and an electrical upgrade to a 200-amp underground conversion completed in 2003.

In the early 2000s, the property underwent work on a concrete retaining wall and fence, with initial permit application filed in March 2000 for replacement of a tilting structure, followed by a permit renewal in June 2002 for the remaining work. Interior improvements include a bathroom remodel completed in 1995, during which a plaster vanity, toilet, and wall tiles were replaced.

The building's recent history has been relatively uneventful, with the only recorded incident being a graffiti report in December 2019, which was investigated and determined to be harmless USA (Underground Service Alert) markings rather than criminal graffiti. The property appears to have maintained compliance with building codes and regulations, with no documented violations or safety concerns on record since the aforementioned structural improvements.
