234 London St, San Francisco, CA 94112

The two-unit residential building at 234 London Street, located in the Excelsior neighborhood, was built in 1906 and is currently owned by Linda Chan and Brian Wong. The property has a documented history of unauthorized modifications and permit violations, most notably in 2004 when multiple violations were filed regarding unpermitted construction of rooms, bathrooms, and a kitchen at the ground level, including the formation of an illegal dwelling unit. These violations were ultimately abated in November 2004.

More recent concerns were raised in June 2022 about potential occupancy overages, with complaints of multiple families residing in the building, exposed wiring, and parking issues associated with the property's use. The building has undergone several permitted improvements over the years, including window replacements in 2015, electrical upgrades in 2004, and a completed sidewalk space permit in 2010. In 2018, there was a hazardous materials complaint that was determined to have no merit by June 2019.

The property has experienced ongoing parking-related issues, with numerous citations issued throughout late 2024 for vehicles blocking driveways and parking on sidewalks. These issues have been consistently documented through 311 calls and parking enforcement actions. Despite the building's age, recent permits have shown efforts to maintain and improve the property, including legal occupancy documentation submitted in 2015, though historical patterns of unpermitted modifications raise concerns about past compliance with building codes and regulations.
