212 23rd Ave, San Francisco, CA 94121

The three-story multi-family residential building at 212 23rd Avenue in San Francisco's Central Richmond neighborhood is a 1906 flats and duplex structure owned by Bernstein Martin D. The property underwent significant renovation work in 2009-2010, including substantial plumbing and electrical system upgrades, bathroom/shower installations, and various housing improvements with a complete rewiring of the entire building. Recent infrastructure improvements include the installation of a hydronic heating system in 2017, comprehensive electrical system upgrades (including new 200-amp service and multiple appliance installations), and various plumbing works.

The building's maintenance history shows attention to critical systems, with three expired plumbing permits from 2010-2013 related to water lines, furnaces, and gas piping, though it's worth noting that some permits remained incomplete. Several concerning events have been recorded over the building's history, though none appear to be current threats. A plywood barricade issue in 2001 (resolved within four days) and a front landing collapse in 1999 (resolved in just over a month) were documented as housing complaints. There have been two fire-related incidents on record, including a minor cooking fire in 1998 and a carbon monoxide detector activation in 2016, neither resulting in civilian injuries.

Recent occupancy-related issues have primarily consisted of parking violations, including multiple cases of driveway blocking and sidewalk parking between 2022-2024, as well as some street cleaning matters. A tree maintenance issue affecting the building was identified in 2022 but was classified as not removal candidate at that time. The building's permit history suggests regular maintenance and upgrading of essential systems, with most recent work focusing on heating, electrical, and plumbing systems, though some permits have expired without final inspections being clearly documented. A CEQA clearance was issued for alteration and remodel work, indicating proper regulatory processes have generally been followed.
