538-540 20th Ave, San Francisco, CA 94121

The two-unit residential building at 538-540 20th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1923, currently owned by the Wayne & Helen Szeto Trust. The building's maintenance record shows a historical reroofing project completed in 1997, though this permit has since expired.

The property has experienced several parking-related incidents between 2019 and 2024, with three documented cases in October 2019 involving a black BMW X3 blocking driveways, one of which required officer intervention and resulted in a citation, while another was addressed but could not be validated when officers arrived. A sidewalk parking incident was reported in November 2019 but could not be validated by responding officers. The most recent incident was recorded in June 2024, involving damaged property that required follow-up communication from the PUC - Billing department, though the case was eventually resolved.

The building's documented history primarily shows routine maintenance and some external infrastructure issues rather than major structural problems or health/safety concerns. The property has experienced occasional issues with neighboring vehicles, particularly between 2019 and 2024, though these appear to be isolated incidents rather than systemic problems. The relatively low number of complaints and incidents over the past several years suggests general stability, with the most recent notable event being the property damage reported in mid-2024.
