322 20th Ave, San Francisco, CA 94121

The two-unit residential building at 322 20th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1922, currently owned by the Hayashi Revocable Living Trust. The building has undergone several significant maintenance and improvement projects over the years, including a $8,500 reroofing project in 2012, window replacements in 1998 (installing 15 windows into existing frames), and street/sidewalk improvements in 2010.

A notable planning record from 1998 indicates that windows in both the front and back of the building were replaced without proper permits, though this case was ultimately closed with no violations found. In recent years, there have been several maintenance and safety-related incidents in the vicinity of the building, though none directly related to the building's structure or systems.

The most recent issues have primarily involved street cleaning matters, with reports of loose garbage in March and May 2024, and the presence of glass reported in June 2022. The building has also experienced minor external issues such as defaced parking signs in 2019 and graffiti on a pole in 2011, neither of which impacted the building's safety or habitability. A scooter-related service request was received in March 2023, which was investigated and resulted in a warning being issued, though this was related to street conditions rather than the building itself.
