622-624 10th Ave, San Francisco, CA 94118

The property at 622-624 10th Avenue in San Francisco's Inner Richmond district is a two-story, three-unit multi-family residential building constructed in 1915, currently owned by Judy L. Cheng.

The building has undergone several significant modifications over the years, with the most recent work occurring in July 2023 when three windows were replaced on the rear facade, complying with eero requirements. The property experienced a notable period of renovation between 2021-2023, prompted by a 2019 complaint about possible unpermitted living space, during which a bathroom, wet bar, and kitchenette were added to the first floor, along with associated plumbing and electrical work. These improvements were completed under proper permits following previous complaints about unpermitted construction.

The building has a history of maintenance and upgrades, including a 200-amp electrical service upgrade in 2007, siding repairs and painting in 2013, and several significant structural improvements in 1991 including horizontal addition, stucco replacement, and kitchen remodeling. Various complaints about permit violations and safety issues have been recorded over the years, including concerns about unpermitted construction in 2012, non-working outlets and fused wiring in 2001, and a roof replacement without proper permits in 2008, though all these issues were eventually abated. Of particular note is the building's involvement in short-term rental activity, as evidenced by multiple Airbnb listings, leading to regulatory scrutiny in 2019 when the property was directed to cease rentals of less than 30 days, a violation that was eventually closed and abated.
