643-645 22nd Ave, San Francisco, CA 94121

The property at 643-645 22nd Avenue in the Central Richmond neighborhood is a two-story, three-unit multi-family residential building constructed in 1988, currently owned by the Amy Yuen Trust. Significant recent improvements include the 2018 legalization of an unauthorized dwelling unit (643A) which added two bedrooms and one bathroom, with no exterior changes.

More recent safety upgrades have focused on fire protection systems, with the installation of a new fire sprinkler system for the ground floor completed in 2021 (at a cost of $15,000), along with a comprehensive fire alarm system. The building has undergone several maintenance updates, including reroofing work completed in early 2020 ($19,800), and recent plumbing and electrical upgrades in December 2022 that included kitchen renovations and the installation of smoke detectors. The property has experienced recurring issues with illegal parking, particularly sidewalk parking, with multiple citations issued between 2019 and 2021, suggesting a persistent challenge in the vicinity regarding parking enforcement.

However, these parking violations occurred on public streets rather than on the property itself. Other service calls have generally been routine in nature, including waste management and street cleaning matters. The building's documented history shows appropriate attention to safety upgrades and maintenance, with all recent permits being properly completed and closed, indicating compliance with local regulations and building codes.
