2354-2356 20th Ave, San Francisco, CA 94116

The two-story multi-family residential building at 2354-2356 20th Avenue in Parkside, owned by Raymond Woo, was constructed in 1946 and contains flats or duplex units. The building's maintenance record shows several significant repair and improvement projects over the years, including a reroofing project completed in 2008 at a cost of $6,500, and window replacements in 1998 when old wood sash windows were upgraded to vinyl framed dual glazed units.

More recently, in 2019, a street space permit was issued with a nominal cost of $1. The property has experienced several infrastructure issues in the surrounding area, particularly in 2016, when there were multiple reports of sidewalk and pavement defects near the building. These incidents included a collapsed sidewalk and a collapsed utility vault, which required immediate attention from the San Francisco Water Department and the Bureau of Street Use and Mapping.

The utility issues prompted multiple service requests and follow-up inspections throughout early 2016, indicating a period of significant external maintenance needs in the immediate vicinity of the property. While these infrastructure issues were eventually resolved, they represent the most notable challenges faced by the building and its surroundings in recent history. The most recent building permit activity from 2019, while minimal in cost, suggests ongoing attention to property maintenance and compliance requirements by the current owner.
