821-823 Pacific Ave, San Francisco, CA 94133

821-823 Pacific Avenue is a 2-story multi-family residential building with commercial space, constructed in 1907 in the Nob Hill neighborhood. The property underwent significant changes in 2018 when major renovations were completed to legalize the upper floor as a residential unit, converting it to a 4-bedroom, 2-bathroom configuration with additional office space.

This work included comprehensive electrical updates, plumbing modifications, and the addition of a bathroom in the commercial space, with permits valued at approximately $118,796. The building has a history of addressing safety concerns, having completed seismic retrofitting in 1996 and compliance with the parapet safety program in 1986. Recent history has been marked by recurring sanitation issues in the vicinity, particularly documented between December 2024 and January 2025, with multiple 311 calls regarding garbage, debris, and human waste on nearby sidewalks, though these were street-related issues rather than building-specific problems.

The building's maintenance record shows attention to infrastructure needs, including sewer trap repairs in 2009 and various interior improvements documented in the 1990s. Fire department records indicate several elevator-related service calls and false alarms, but notably, there have been no reported civilian injuries associated with any incidents. The commercial space portion of the building has seen business transitions, including a recent retail transfer approval in 2023 from Great Wall Ginseng and Herbs to New Wing Lung Food.
