2709-2711 20th St, San Francisco, CA 94110

The two-unit residential building at 2709-2711 20th Street in San Francisco's Inner Mission neighborhood, owned by Gabriel Yu and Wai Hin Cheung, is a two-story flats and duplex structure built in 1900. The property has experienced significant maintenance issues, most notably in 2005 when multiple violations were documented under complaint #200558208, including problems with heating, plumbing, electrical systems, security doors, and interior surfaces. While some repairs were attempted, with permits issued for stair, window, ceiling, and tub repairs totaling $2,000, as well as electrical corrections, the violations remain active as of 2023.

The building has undergone several infrastructure improvements over the years, including a roofing project completed in 1990 and basement wall repairs in 1984. More recent work includes the installation of a new furnace and ductwork in 2008, and electrical improvements in 2009 to the flat, rear deck, and common areas. The property has been subject to numerous parking enforcement issues in recent years, with multiple citations issued between 2020 and 2024 for vehicles blocking driveways and sidewalk parking violations, though many of these cases resulted in officers being unable to locate the offending vehicles.

A sidewalk defect was reported and resolved in 2021, involving missing service and a sunken utility vault. Despite the age of the building and the history of repairs and violations, the property has maintained its class as a multi-family residential building, though the persistence of some active violations from 2005 warrants attention. The owners have demonstrated efforts to address various maintenance issues over the years through the acquisition of appropriate permits and authorized work.
