509-511 Buchanan St, San Francisco, CA 94102

The 4-unit, 2-story multi-family residential building at 509-511 Buchanan Street in Hayes Valley, owned by Rosaire Properties LLC, has undergone several significant maintenance and repair projects since its construction in 1900. Most notably, in January 2016, the building sustained structural damage when a motor vehicle struck its foundation and load-bearing wall, requiring $15,000 in repairs to the brick stem wall and wood cripple wall in the crawlspace/basement, which were completed in July 2017.

In 2013, substantial improvements were made including the installation of a new 200-amp electrical service with five meters and panels, kitchen renovations in unit B, plumbing upgrades, and repairs to the exterior wood deck and staircase, totaling approximately $23,000. The building has a history of addressing maintenance issues, with a 2006 violation prompting multiple repairs including stair repairs, water heater maintenance, and concerns about lead paint that were all resolved by 2017. Recent history shows active maintenance of the property, with routine safety inspections being conducted in 1996, 2000, 2006, 2010, and most recently in 2018.

The building has experienced periodic issues with the surrounding area, as evidenced by multiple 311 calls between 2021 and 2024 regarding sidewalk cleaning and garbage concerns. The property underwent various repair works and improvements over the years, including a 2008 repair of damaged decking boards and a 2013 kitchen cabinet and flooring upgrade, demonstrating ongoing maintenance efforts by the ownership. While the building has had its share of maintenance issues and violations over the years, records indicate that these have generally been addressed through appropriate repairs and improvements, particularly the significant structural work following the vehicle collision incident.
