801-803 Columbus Ave, San Francisco, CA 94133

The property at 801-803 Columbus Avenue in Russian Hill is a three-story, multi-family residential building with three units, constructed in 1933, and includes retail space. The building has experienced several significant issues in recent years, most notably a November 2023 violation regarding unpermitted modifications to the commercial space, including the installation of a wet bar, full bathroom, and loft. This violation, which resulted in a March 2024 permit requirement to remove unpermitted work, appears to be closely related to two complaints filed in 2023 regarding unauthorized residential occupancy of the commercial space.

The building has a history of maintenance and safety concerns, including an active lead paint hazard violation from 2017, and problems with water drainage systems documented in complaints from 2006 and 2012. Earlier maintenance work includes a complete reroofing project completed in 2018 at a cost of $24,500, and structural underpinning work in 2003. The property has had multiple fire alarm responses, though none resulted in injuries or confirmed incidents, including false alarms and a gas leak in 2014.

Recent exterior maintenance issues have been documented through 311 calls, with reports of garbage, debris, and tree overgrowth affecting the property. The commercial space has a documented history of unauthorized use as a private nightclub and music venue (2018), and there have been multiple inquiries regarding its proper use and occupancy status. The building's current owners are required to remove unauthorized modifications and ensure proper use of the commercial space to comply with recent planning enforcement actions.
