943 Columbus Ave, San Francisco, CA 94133

The three-story, four-unit multi-family residential building at 943 Columbus Ave in Russian Hill, constructed in 1927, has undergone several significant renovations and maintenance projects over the past two decades. Most notably, there was a substantial restaurant remodel in 2013 costing $75,000, during which a UL300 fire system was installed and comprehensive electrical work was completed, including rewiring of the entire unit and first floor. The building has received regular maintenance including reroofing in 2014, installation of vinyl siding with foam insulation in 2006, and various unit-specific improvements.

A concerning incident occurred in April 2020 involving unauthorized water shutoff that affected the entire building, though this complaint is now listed as not active. The building experienced a series of fire safety violations in late 2005, including issues with fire escape ladders, fire extinguishers, and smoke detector requirements, though these were all abated by December 2005. More recent fire complaints in late 2016 regarding blocked exits and exit maintenance were also corrected.

The property has maintained a good safety record since then, with two cooking-related fire incidents recorded but with no civilian injuries reported in either case. Recent maintenance records show regular upkeep, including street space permits in 2013 and 2015, though there have been recurring issues with sidewalk blockage due to scooters, with multiple reports from 2024. The building's infrastructure has been systematically upgraded, with significant plumbing and electrical work completed in various units between 2006 and 2013. The most recent documented building issues have been primarily related to street-level conditions rather than building-specific problems, with multiple reports in 2024 regarding sidewalk debris and cleaning needs, though many were resolved without requiring action.
