747-749 20th Ave, San Francisco, CA 94121

The two-unit residential building at 747-749 20th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1923, currently owned by the Wong Calvin Y & Mai T Trust. The building has undergone some significant improvements over the years, most notably a substantial renovation in October 2017 that included the installation of a replacement window facing the backyard garden and conversion of wooden sidings to more durable Hardie cement plank sidings, along with CDX wood sheathing, with a documented cost of $30,000.

Additionally, there is a historical record of reroofing work completed in March 1997, though this permit has since expired. The property has experienced numerous parking-related incidents in the surrounding area, particularly during 2019-2024, though these incidents have not directly involved the building itself.

There were eight reports of abandoned vehicles or illegal parking situations, including multiple cases of vehicles that were gone by the time authorities arrived, one instance of an unverified parking issue, and one case where a citation was issued. The most recent incident reported was an abandoned vehicle case from August 2024, with all external incidents resolving without direct impact on the property. While these parking issues appear to be a recurring theme in the neighborhood, they seem to be managed through appropriate channels as demonstrated by the various agency responses recorded in the 311 call data.
