3151-3155 23rd St, San Francisco, CA 94110

The building at 3151-3155 23rd Street in San Francisco's Inner Mission neighborhood is a two-story multi-family residential structure built in 1880, containing four units plus ground floor commercial space, currently owned by Richard D. Fong and Kerri Ma. The property has undergone several significant modifications since the mid-1980s, including foundation work and staircase replacement in 1985, and multiple attempts to establish a coin-operated laundry facility in the early 1990s.

While most building permits from 1988-2009 are now expired or completed, the property has experienced notable maintenance and safety issues, particularly in a serious 1997 complaint that documented rodent and roach infestations, severe water damage, non-functional fire alarms, and plumbing problems, though these were resolved by August 1998. Recent building activity is primarily centered around external maintenance, with multiple 311 calls in late 2024 regarding garbage and debris on the street and sidewalk. While these calls were consistently resolved, they indicate ongoing issues with waste management in the immediate vicinity.

A 2009 housing inspection complaint marked as "routine" was resolved by February 2010. Of particular note, the property was briefly leased to the Mission Mental Health Clinic for approximately three years, though this arrangement has since ended. The building's historical records show regular maintenance and improvement efforts by various owners over the decades, with the most recent significant building permit related to street space and sidewalk repair issued in 2009. All records indicate that there have been no recent fire incidents or civilian injuries associated with the building.
