271-273 23rd Ave, San Francisco, CA 94121

The property at 271 23rd Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1925 and currently owned by the Ada Y Hom 1991 Living Trust, this flats/duplex-style building has undergone several significant improvements in recent years. Most notably, between 2023 and 2024, the building received substantial window and roof upgrades, including the replacement of multiple windows with energy-efficient retrofit options, costing approximately $28,430 in 2023, followed by a revision in 2024 that modified the scope to include 11 windows with aluminum wood-clad materials.

The building also received a new roof in March 2024, with the roofing work valued at $16,000. Historical records show an earlier roofing project completed in 1992. The property has been subject to various municipal service calls over the past few years, primarily related to street and sidewalk maintenance issues.

The most recent concerns include a pavement defect reported in August 2024 and two instances of human or animal waste removal in 2022. There have been several parking-related incidents in the vicinity, including two cases of driveway blocking in 2024 and 2021. The building's surroundings have experienced typical urban maintenance issues, as evidenced by multiple street cleaning calls, including responses to general cleaning needs, overflowing garbage cans, and one Christmas tree removal request in early 2023. While these external issues don't directly impact the building's structural integrity, they do provide context about the immediate neighborhood environment.
