242 20th Ave, San Francisco, CA 94121

This two-unit multi-family residential building, located at 242 20th Avenue in the Central Richmond neighborhood, is a two-story flats and duplex structure built in 1907, currently owned by Lina Chan Lee. The building has undergone some maintenance over the years, including a reroofing project in 1995 and a water heater replacement in 2019.

A significant compliance issue arose in October 2011 when multiple violations were filed regarding defective vent pipes in the north lightwell, which were eventually abated by February 2012 after receiving multiple Notices of Violation and a Final Warning Letter. The property has generated numerous 311 calls between 2019 and 2024, primarily related to street cleaning and garbage issues, with the most recent incidents occurring in November 2024 involving garbage and debris.

Several parking enforcement calls have been made regarding driveway blocking between 2019 and 2022, though enforcement officers were often unable to locate the offending vehicles. The building's only recorded fire incident was a false alarm. While the property has experienced some maintenance issues in the past, there are no active violations or ongoing tenant buyout cases on record.
