3167 23rd St, San Francisco, CA 94110

The property at 3167 23rd Street in San Francisco's Inner Mission neighborhood is a six-unit multi-family residential building constructed in 1906. The building has undergone several significant maintenance and upgrade projects over the past two decades. Most notably, in 2003-2004, the building underwent extensive repairs including window, bathroom, sink, and flooring repairs, roof replacement, and heating system upgrades, with a total estimated cost of $25,000 plus $8,780 for roofing alone.

During this period, the property faced multiple violations related to interior surfaces, plumbing, and electrical systems, including issues with mold/mildew, water damage, floor covering, and various fixture repairs, all of which were officially abated by February 2004. The building's infrastructure was further improved through a series of important upgrades, including electrical system modernization with meter replacements (2006), rear cottage electrical repairs (2003), and a complete sewer replacement (2009). More recent maintenance includes street space usage permit in 2009 and gas heater replacement in 2004.

The property underwent routine housing inspections in 2011 and 2014, and while there have been numerous 311 calls in the vicinity since 2022, most relate to public space issues rather than building-specific concerns. The most recent building-related complaint was in 2024 regarding general cleaning, which remains open. A notable current issue is a collapsed sidewalk reported in March 2023, which is still listed as open. The building's last recorded planning action was for a DPH referral related to Cottage Food Operator status, which was approved.
