627 41st Ave, San Francisco, CA 94121

The property at 627 41st Avenue in San Francisco's Outer Richmond neighborhood is a two-story, five-unit multi-family residential building constructed in 1962, currently owned by Knowland G & Lika Yu Ng Rev. The building has experienced several significant maintenance and safety issues over its history, with the most recent concerns arising in early 2023 regarding unauthorized structural work and unpermitted bathroom remodeling, though these complaints have since been marked as "Not Active." In 2002, the building went through a period of multiple violations requiring attention to various safety systems, including fire escape maintenance, central alarm system repairs, and fire proofing, all of which were abated by June 2002.

More recently, in 2016, a wall heater was installed, and a reroofing project was attempted in 2003. The building has faced recurring issues with garbage disposal systems, plumbing fixtures, and general maintenance problems, as evidenced by complaints in 2001-2002 and 2024.

Multiple 311 calls in late 2023 and 2024 have been logged regarding litter receptacle maintenance, suggesting ongoing challenges with waste management in the vicinity of the building. The most recent tenant buyout in the neighborhood, at 618 42nd Avenue, occurred in July 2024 for $110,000 involving one tenant, though it is unclear if this directly relates to the subject property.
