571-573 6th Ave, San Francisco, CA 94118

The two-unit residential building at 571-573 6th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1905 and owned by Wong Geequen. The property has a documented history of air ventilation system issues, most notably in April 2019 when a complaint was filed regarding problems with the fresh air inlet system including a missing perforated cover, clogging issues, and concerns about a house trap installation.

This violation, which fell under the city's plumbing regulations, was officially noted on April 12, 2019, though the current status is listed as not active with no clear indication of resolution date. The building has experienced recurring parking-related issues in recent years, with multiple incidents between 2023 and 2024 involving vehicles parking on sidewalks or blocking driveways. Most of these incidents involved the same vehicle (a Toyota) occurring weekly or bi-weekly during mid-2023, with at least two citations issued and several instances where officers were unable to locate the offending vehicle.

The most recent parking complaint was filed in February 2024 regarding sidewalk parking, resulting in a citation. Prior to this, there were also abandoned vehicle complaints recorded in April 2019 and 2018, though these vehicles were gone upon officer arrival. While these parking issues affect the street environment around the building, it's important to note that they occurred in public spaces rather than directly affecting the property's infrastructure or residential systems.
