301 28th Ave, San Francisco, CA 94121

The three-story, mixed-use building at 6619 California Street in the Central Richmond neighborhood, constructed in 1911, contains three residential units and is currently owned by the Wing K Quock Trust. The property has experienced several significant maintenance and compliance issues over recent years, most notably a cluster of building violations in 2017 that required attention to building safety and habitability concerns, including repairs to weatherproofing on exterior walls and windows, floor coverings, and the installation of carbon monoxide detectors. These violations, along with associated water leak and mold problems, were all abated by May 2017.

More recent issues include a water leak complaint in May 2022 and several plumbing concerns, including the replacement of a water heater in September 2021 and problematic water quality issues in 2021. The building has undergone various structural modifications over its history, including a 1985 one-story addition and partial reroofing work in 2017. A notable recent development is the ongoing work to comply with accessibility requirements, with a permit filed in October 2023 for the installation of a push-button door operator. The property's approved planning records indicate successful legalization of a third dwelling unit (Unit No.

6623) in 2017, along with various other improvements including facade restoration and stair replacement. The building has experienced a few fire department calls, primarily for equipment problems and alarm malfunctions, though none resulted in civilian injuries. While the property has a history of maintenance issues, most violations and complaints have been resolved through proper channels, though some recent concerns about water quality and leaks persisted for extended periods. The three-unit building is currently focusing on accessibility improvements, as evidenced by the most recent permit application, suggesting ongoing commitment to building maintenance and compliance, though this work has not yet been completed as of October 2023.
