2219-2221 Steiner St, San Francisco, CA 94115

The property at 2219-2221 Steiner Street is a two-unit residential building located in San Francisco's Pacific Heights neighborhood, constructed in 1940 and consisting of two stories with a garage. The current owners, George Chen, have proposed significant modifications to the building, including both horizontal and vertical additions, reconfiguration of unit layouts, facade improvements, and expansion of the roof deck. These proposed changes, which would add a fourth floor to the structure, were initiated through a permit application in January 2025, though similar proposals from February 2024 were cancelled.

Historical records show a completed horizontal extension with an 8'x11' sun deck in 1986. Previous modification attempts include unauthorized construction of a roof deck in 2011 and 2012, though these complaints were subsequently abated. The property underwent significant infrastructure upgrades in 2009, including the installation of a new water heater system and a complete electrical service upgrade to 200-amp service with multiple meters and panels.

More recently, the building's area has experienced several quality of life issues as documented in 311 calls throughout 2023-2024, including reports of garbage and debris, graffiti on mailboxes, and a pavement defect. While some of these issues were resolved or transferred to appropriate authorities, an open pavement defect case remains as of April 2024. A notable building complaint from December 2014 regarding alleged commercial use of the garage has been marked as inactive, and no recent fire or safety incidents have been reported.
