520 Holloway Ave, San Francisco, CA 94112

The property at 520 Holloway Avenue is a two-story, three-unit multi-family residential building constructed in 1926 and owned by Yu Zhuo Cheng & Lily Li. The building underwent significant improvements in the late 2000s, including a substantial vertical addition and remodel completed in 2004 ($344,000), followed by the installation of a comprehensive fire safety system in 2008 that included sprinklers throughout the building ($18,000) and a new fire alarm system ($4,000). Additional plumbing and electrical upgrades were performed in 2008, including the installation of new kitchens, bathrooms, and modern electrical systems.

A solar panel system was added in 2011, demonstrating commitment to energy efficiency. The building has experienced several notable issues over its history, particularly between 2000 and 2003, including multiple violations related to safety concerns such as deteriorated exhaust ducts, utility shut-off tool requirements, egress obstructions, window repairs, and drainage pipe issues. These violations were all properly abated by November 2000.

Recent complaints have focused primarily on parking issues around the property, with multiple reports of sidewalk parking and toter management between 2023-2024. Two significant complaints regarding unauthorized construction were filed in 2009 and 2011, though these were eventually resolved. A recent fire complaint from 2013 was found to have no merit, and there are no recorded civilian injuries from any fire incidents associated with the property. The building's maintenance history shows regular inspections and prompt attention to safety concerns, particularly regarding fire safety systems, which are now in place throughout the building.
