559-561 20th Ave, San Francisco, CA 94121

The property at 559-561 20th Avenue in the Central Richmond neighborhood is a two-story multi-family residential building constructed in 1918, containing 3 units and classified as Flats & Duplex. The building has experienced several significant maintenance and compliance issues over recent years, most notably a recent remodel of kitchen and bathroom spaces in 2024 (completed at a cost of $64,315) that was initiated in response to an earlier complaint about unpermitted interior work.

This recent renovation included plumbing and electrical updates, with a water heater replacement also issued in July 2024. The building has a documented history of unauthorized modifications, including a 1999 incident involving an illegal apartment in the back, and more recent concerns in 2012 regarding plumbing issues that resulted in water damage and heating problems. The property has undergone various legitimate improvements and maintenance work over the years, including the legalization of additional rooms and bathroom facilities in 1997, and structural work such as reroofing in 1995 and staircase replacement in 1984.

Several building violations have been recorded and subsequently resolved, including flue installation issues in 2009, which was abated in 2012, and concerns about unauthorized kitchen installations. The building's maintenance history shows a pattern of requiring compliance work to address various violations, most recently in 2024, suggesting ongoing challenges with maintaining consistent adherence to building codes and permit requirements. While many historical issues have been resolved, the most recent complaints and permit activity in 2024 indicate that some challenges with unauthorized modifications and compliance with building codes persist.
