471 6th Ave, San Francisco, CA 94118

The property at 471 6th Avenue in the Inner Richmond is a two-story, 4-unit multi-family residential building constructed in 1974 and owned by Chen Chan Chuan. The building has undergone significant renovations over the past decade, with the most recent major work occurring in 2019 when twelve front windows were replaced with Milgard aluminum series windows to comply with building codes.

Prior to this, in 2018-2019, substantial remodeling occurred in multiple units, including renovations to kitchens, bathrooms, and bedrooms across units 1, 3, and 4, with an initial complaint in 2018 regarding potentially structural changes involving kitchen wall removal. The building experienced several notable issues between 2015-2019, including multiple fire safety violations in 2019 related to blocked exits, fire extinguishers, combustible materials, and sprinkler systems, though these were subsequently corrected and abated. There have been past concerns regarding unauthorized work, as evidenced by a 2019 complaint about unpermitted window replacements, though this was later addressed through proper permitting.

The building underwent routine housing inspections in 2002, 2010, and 2015, and has had several maintenance updates including a new roof in 1988 and 2004, and the installation of AC stair lifts in 2011. Recent infrastructure issues include documented flooding and sewage backup incidents in 2024, suggesting potential ongoing plumbing system challenges. The property has had periodic issues with parking enforcement, mechanical equipment noise, and various environmental maintenance matters as recorded in 311 calls.
