522-524 5th Ave, San Francisco, CA 94118

The two-story, four-unit multi-family residential building at 522-524 5th Avenue in the Inner Richmond, owned by the Woo Family Revocable Trust, has a significant history of maintenance and safety compliance issues since its construction in 1909. The most recent major work was completed in 2024 with a sewer line repair and house trap replacement. Previous electrical upgrades in 2009 included the addition of a house meter for common area lighting, and a reroofing project was completed in 1989.

The building underwent several routine safety inspections between 1999 and 2016, revealing multiple fire safety concerns. These included violations related to wood stairs, carbon monoxide alarms, fire extinguishers, combustible storage, fire proofing materials, and smoke enclosure door closures, though all were abated by March 2016. The property's more recent history shows continued maintenance attention, including street space permits in 2012 and prompt response to various building system needs.

The building has experienced some environmental issues, with a complaint about mold in 2010 that was resolved in 2012. Recent maintenance activity has been minimal, and the property has generated regular parking enforcement calls between 2018 and 2025, primarily for driveway blocking and sidewalk parking violations. Street cleaning issues have been reported as recently as 2024, though these appear to be external to the building itself. The building's overall permit and violation history suggests a pattern of addressing safety and maintenance concerns promptly when they arise, though with periodic fire safety violations occurring primarily during the 2005-2016 period.
