1234 23rd Ave, San Francisco, CA 94122

This two-story, three-unit multi-family residential building located at 1234 23rd Ave in the Central Sunset neighborhood was built in 1911 and is currently owned by Kim Alexander Y H & Patrici. The property has experienced several significant maintenance and safety issues over its history, with the most pressing concerns being a series of sewage-related problems in 2024, including multiple sewage back-up discharges from catch basins and a side sewer vent. Other notable recent improvements include the installation of new front stair rails for code safety in 2016, and various plumbing updates between 2013-2015, including the replacement of a water heater and sewer repairs.

The building has a documented history of violations and complaints from 2000-2016, particularly during 2013 when there were multiple issues including lack of hot water, exposed electrical wiring, and hallway lighting problems, though most of these issues appear to have been resolved by 2015. The property has undergone several significant structural modifications over the years, including the conversion of attic space and legal basement apartment work in 1986. Earlier maintenance records show roofing work was performed in 1998, however, this permit has since expired.

Recent complaints in 2024 regarding the building's curb defect and waste management suggest ongoing maintenance challenges, while multiple parking enforcement calls indicate recurring issues with driveway access. The most recent tenant buyout in the vicinity occurred at 1238 23rd Avenue in 2022 for $35,000. While many historical violations have been addressed, the recent pattern of sewage-related problems and ongoing maintenance issues suggests continued attentiveness to building systems is required.
