2821 Polk St, San Francisco, CA 94109

The 4-unit, 2-story multi-family residential building at 2821 Polk Street in Russian Hill, owned by Stephen J Schwab and Bai Shan, has undergone substantial renovations over the past few years. Between 2019-2020, the property underwent significant improvements to all four units, including comprehensive kitchen and bathroom remodels, electrical rewiring, hardwood floor replacements, and window upgrades, with individual unit improvements costing between $42,000 to $49,000 each. In addition to these interior renovations, the back house received new siding in July 2020, and several mechanical upgrades were completed during this period including a new furnace, tankless water heater, and the installation of a gas fireplace.

The building's history shows earlier substantial work in 2002-2003 when unit #1 was enlarged with structural modifications including the installation of a steel beam. Safety systems were addressed during recent renovations, including the installation of a 70-amp subpanel in apartment 3 and various electrical upgrades. The property has maintained compliance with housing inspections, showing no significant recent violations.

While there have been multiple 311 calls regarding street cleaning needs and waste removal in the vicinity of the building between 2022-2025, these primarily relate to public sidewalk issues rather than building-specific concerns, and most have been resolved promptly. The building has experienced several alarm system activations over the years, though all were determined to be false alarms or system malfunctions with no reported injuries or actual fires. Prior permits from the 1990s and earlier demonstrate attention to fundamental building safety, including roofing work and seismic improvements such as bolting the mudsill to the foundation and plywood installation to basement walls.
