476-480 Duboce Ave, San Francisco, CA 94117

The three-unit, three-story multi-family residential building at 476-480 Duboce Avenue in Hayes Valley, owned by Brigitte & Anglito Uson, has a construction history dating back to 1900. The property has undergone several significant maintenance and infrastructure upgrades, most recently completing a sewer line replacement from foundation to house trap in February 2024, which suggests active maintenance of essential systems.

Previous improvements include the replacement of three console heaters in 2013 and various structural repairs in 2020 involving non-street visible siding boards at the back porches. A notable cluster of violations was recorded in March 2009 related to fire safety, lead paint hazards, and structural issues, though all were abated by May 2009, demonstrating responsive management to regulatory requirements.

The building has maintained compliance with safety measures since these violations were addressed. The property has experienced recurring issues with graffiti and street cleaning matters in the immediate vicinity, with several reports between 2022 and 2024, though these are external to the building itself. The most recent documented works, including the 2024 sewer line replacement, indicate ongoing commitment to building maintenance, while the resolution of past violations suggests improved building management practices.
