358-360 20th Ave, San Francisco, CA 94121

The property at 358-360 20th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, built in 1907 and currently owned by Wong Fan Wa. The building has undergone several significant structural improvements over the years, including seismic upgrades and foundation repairs completed in 1996 (with associated dry rot repairs), and interior alterations in 2001 that added two rooms including a study and bedroom on the ground floor.

However, the property has faced notable regulatory challenges, most significantly in March 2001 when a complaint was filed regarding an unauthorized three-room apartment with full bathroom and kitchen on the ground floor, resulting in violations for improper construction without permits, inadequate fire safety features, and minimum ceiling height violations. This complaint was eventually abated by March 28, 2001. The building's maintenance history includes several residential plumbing issues, including malfunctioning shower systems reported in late 2003, and more serious concerns documented in 1999 such as water leaks through light fixtures, ceiling issues, unsafe stairways, and access problems to utility meters.

More recent activity at the property primarily involves external maintenance and neighborhood issues, with multiple 311 calls between 2017 and 2025 regarding sidewalk cleaning, garbage collection, and parking enforcement. The most recent building permits on record from 2010 were for sidewalk and street space improvements, indicating some attention to public space maintenance, though these are relatively minor compared to earlier structural work. The property's history shows a pattern of addressing significant structural issues (like the 1996 seismic upgrades) while also contending with ongoing maintenance and compliance challenges, particularly during the late 1990s and early 2000s.
