719 21st Ave, San Francisco, CA 94121

The two-unit residential building at 719 21st Avenue in San Francisco's Central Richmond neighborhood is a two-story flats/duplex structure owned by the Chi Family Trust and constructed in 1922. The building's maintenance record shows minimal documented work, with the only permit on file being for reroofing completed in 1993, though this permit has since expired.

The property has generated several 311 calls over the past few years, with the most recent incident occurring in December 2024 involving a driveway blocking situation that resulted in a citation being issued. Two noise-related complaints were filed during 2022 and 2020, with the latter being deemed invalid when reported through the incorrect channel.

A general cleaning issue involving loose garbage was reported and resolved in February 2022. While the building's permit and complaint history isn't extensive, it's worth noting that the relatively few permits on record since its 1922 construction might suggest limited documented maintenance activity, though this doesn't necessarily reflect the current condition of the building.
