731-733 21st Ave, San Francisco, CA 94121

The two-unit residential building at 731-733 21st Avenue in the Central Richmond neighborhood, owned by Kerrie and Sean Malone, is a two-story flats and duplex structure built in 1923. The building's maintenance and improvement history includes a significant kitchen remodeling project in 2007 that involved electrical upgrades (including new switches and receptacles), plumbing work (sink gas line installation), and cabinet replacements, though these permits are now expired.

Prior to this, the property underwent window improvements in 2005 with the installation of 11 vinyl windows, and received a complete reroofing in 1988. The building's more recent history has been marked by numerous parking-related incidents, with eight documented cases of driveway blocking between 2020 and 2024, resulting in several citations issued to offending vehicles.

Each incident was addressed by responding parking enforcement officers, though in some cases the vehicles were not located or other resolutions were noted. The property has also required general sidewalk and street cleaning services, as evidenced by three separate incidents of loose garbage reported between December 2020 and April 2021, though most of these cases were resolved promptly, with at least one resulting in no debris being found. While the building's structural and systems maintenance appears to have been regularly attended to based on permit records, the more recent history shows a pattern of parking enforcement issues in the vicinity of the property.
