475-477 Arlington St, San Francisco, CA 94131

The duplex at 475-477 Arlington Street in Glen Park, built in 1975 and owned by the Chan/Yuen Family Trust, has undergone several significant improvements and faced some regulatory scrutiny over its history. The property has seen consistent window upgrades over the years, with recent work in 2016 replacing six windows in the back of the building with wood windows, following a 2014 installation of four energy-efficient Anderson Fibrex windows facing the street.

Other notable improvements include a complete reroofing in 2008, kitchen renovations in 2005 (which initially prompted a building violation for unpermitted work that was later resolved), and electrical upgrades including the installation of five new receptacles in 2005. The building's history includes multiple inspections regarding potential unauthorized unit conversions, with complaints filed in 1996, 1997, and 1999 concerning possible illegal units in the garage and various living spaces, though these issues were documented as resolved.

Safety features have been maintained, with records showing fire sprinkler system renewals in 1995. More recently, from late 2022 through 2025, there have been recurring issues with parking violations near the property, particularly concerning blocked driveways and abandoned vehicles, though these are municipal issues rather than building-specific concerns. The most recent documented building work was the 2016 window replacement project, which represents the latest investment in the property's maintenance and improvement.
