1437-1439 23rd Ave, San Francisco, CA 94122

The property at 1437-1439 23rd Avenue in the Central Sunset neighborhood is a 2-unit, 2-story multi-family residential building constructed in 1939, currently owned by the Deborah Quock Living Trust. The building has undergone several significant modifications and repairs over the years, with the most recent being a complete re-roofing project costing $12,000 completed in October 2024. Notable historical events include a period of regulatory scrutiny in 2006 when the building faced multiple violations related to an unauthorized ground floor unit.

These violations, documented through several complaints and violation notices, involved unpermitted living and business spaces, including office rooms, a wet bar area, and an improperly installed bathroom. The violations were ultimately resolved by November 2006 through proper permit acquisition and modifications. More recent building maintenance includes electrical upgrades in 2006, such as the installation of a 150A feeder and various electrical fixtures.

The property has also experienced some maintenance and safety concerns, as evidenced by a collapsed sidewalk report from November 2024 (currently open) and a public health complaint that was transferred to the San Francisco Department of Public Health in October 2024. The building's history shows regular upkeep, with various improvements and repairs documented through building permits, though there have been occasional issues with parking violations and waste management in the surrounding area, as reflected in multiple 311 calls between 2022 and 2024. A minor cooking-related fire incident was recorded with no civilian injuries.
