Augrented Insights Report

The Wong Family Trust's property at 270 21st Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, constructed in 1922. The building's history reveals several significant events, most notably a code enforcement issue in 2008-2009 when an unauthorized third dwelling unit was discovered on the ground floor behind the garage. This illegal unit, consisting of two bedrooms, a living room with kitchen, and a full bathroom, prompted the owner to undertake compliance work in 2009, including the removal of the unauthorized kitchen and bathroom facilities, which was completed with associated plumbing and electrical permits at a cost of $20,000.

The building's maintenance history includes a reroofing project completed in 1998 and a street space permit issued in 2015. More recently, the property has experienced numerous parking-related issues, with multiple complaints about vehicles blocking driveways and parking on sidewalks recorded between 2022 and 2024. There have been at least eight parking enforcement calls in this period, though many resulted in officers being unable to locate the offending vehicles.

The most recent incident occurred in July 2024 involving a sidewalk parking violation. Other community maintenance matters include the removal of an abandoned vehicle in July 2023 and a Christmas tree pickup in January 2023. While the building's major code compliance issue from 2008-2009 has been resolved, the property has experienced ongoing challenges related to on-street parking violations in the surrounding area.
