520 Buchanan St, San Francisco, CA 94102

The 19-unit, 3-story multi-family residential building at 520 Buchanan Street in Hayes Valley, owned by 520 Buchanan Street LLC, has undergone significant renovations and faced several notable issues since its construction in 1924. Most recently, in late 2024, substantial work is being done in Unit #11, including kitchen remodeling and interior improvements, with permits totaling over $96,000. The building has seen considerable unit renovations between 2019 and 2021, including conversions of kitchens to bedrooms and vice versa in Units #6, #11, #17, and #26, along with electrical upgrades, bathroom rehabilitations, and modernization of various systems.

A significant fire safety upgrade was completed in 2021 with the installation of low-frequency sounders in sleeping areas, while 2024 saw recurring fire safety violations related to sprinkler systems, alarm systems, and UL certification that were subsequently noted as requiring correction. The property has a history of maintenance and compliance challenges, particularly around 2015-2016, when there were multiple violations including water damage, inadequate heating, and concerns about construction work being performed without proper permits. A notable complaint was filed in 2020 regarding non-essential construction during health orders, and in 2016, concerns about lead dust and water intrusion were documented.

However, many of these historical issues appear to have been addressed, as evidenced by more recent renovation activity focusing on unit modernizations and system upgrades. The building has completed its soft-story seismic retrofit requirements, achieving Tier 2 compliance. Recent maintenance records show regular plumbing and electrical work being performed, though the property has experienced some recurring issues with fire safety compliance that have required attention.
