Augrented Insights Report

The 6-unit multi-family residential building at 521 Arguello Blvd in San Francisco's Inner Richmond neighborhood, owned by Philip & Mildred Wong since 2014, was constructed in 1971 and is classified as a 2-story apartment building. The property has undergone two significant roofing projects: a recent reroofing in 2019 costing $10,250, and an earlier reroofing in 1994, though the latter permit has expired.

The building's history includes four routine housing inspections between 2001 and 2016, with most notable issues arising from the 2001 inspection when multiple fire safety violations were recorded, including egress obstruction, fire extinguisher maintenance, and gas meter instructions - all of which were resolved by June 29, 2001. A similar egress obstruction was documented in the 2010 inspection, which was resolved by September 2011. Recent external issues around the building (2022-2024) have primarily involved street-level concerns, including multiple reports of bicycle lane blocking (most frequently), and various street cleanliness matters such as garbage, debris, pavement defects, and encampment reports.

While these recent incidents suggest ongoing challenges in the immediate vicinity, they are primarily related to street conditions rather than the building itself. The most recent building-related inspection on record was a routine safety inspection conducted in 2016, though no significant violations or complaints have been recorded since then. The property's documented history shows previous fire safety concerns were addressed promptly, and recent building maintenance (roof replacement) indicates ongoing upkeep of the property infrastructure.
