260 San Jose Ave, San Francisco, CA 94110
260 San Jose Avenue, a 27-unit, 3-story multi-family residential building constructed in 1928 in Noe Valley, is currently undergoing significant modernization efforts under the Zanco Trust ownership. The most notable recent development is the addition of seven ADUs (Accessory Dwelling Units), completed in 2023, which included comprehensive upgrades to fire safety systems with new sprinklers and a fire alarm system, as well as hydronic heating modifications to support the new units. The building has been actively undergoing seismic improvements, with a completed soft-story retrofit in 2022, and recent structural work including retaining wall reinforcement in 2023.
Recent safety upgrades include the installation of low-frequency sounders in 2023 to enhance fire alarm capabilities. The property has a history of addressing maintenance and safety concerns, with several fire safety violations documented between 2010 and 2023, though most have been corrected, including recent issues with sleeping area requirements as of November 2023. Previous building violations from 2016 related to interior surfaces and lead hazards were marked as abated by July 2016.
The building's mechanical systems have undergone substantial updates, including multiple boiler replacements and hot water system improvements between 2021-2023. Recent complaints in 2024 regarding property encroachment and construction-related issues were quickly investigated and closed. While there have been various maintenance issues reported over the years, including heating and plumbing concerns in 2021-2022, the property's recent permit activity and responses to violations suggest active management and ongoing improvements to building systems and safety features.
