845-847 Columbus Ave, San Francisco, CA 94133

The two-unit residential building at 845-847 Columbus Avenue in Russian Hill, managed by 845 Columbus LLC, is a two-story flat and store structure built in 1907. The property has undergone several significant renovations in recent years, including a complete reroofing project in 2020 costing $6,000, and substantial interior upgrades in 2019-2020 that included kitchen, bathroom, and living room remodeling with associated electrical and plumbing work totaling approximately $27,500.

Window replacements were also carried out in 2019, involving installation of double-hung wood windows with integrated ogees in the front facade. Recent concerns pertain primarily to external conditions around the property, with multiple 311 calls (nine in total between June and December 2024) reporting issues with garbage, debris, and human waste on the street, though these are public space concerns rather than building-specific issues. There was one reported incident of disorderly behavior related to Muni services in November 2024.

A notable historical incident involved a cancelled investigation in 2021 regarding potential unauthorized short-term rental activities through Airbnb and VRBO platforms, though this was subsequently addressed through platform coordination. The building's maintenance record shows attention to basic upkeep and improvements, with completed permits indicating proper oversight of both structural and aesthetic enhancements. Two fire safety complaints from February 2012 regarding fire extinguishers were documented but marked as "Condition Corrected."
