1901-1907 Union St, San Francisco, CA 94123

The three-story multi-family residential building at 1901-1907 Union Street in Cow Hollow, built in 1900 and currently owned by 1901 Union LLC, has undergone significant recent improvements and faced ongoing regulatory challenges, particularly regarding its rooftop deck. Most notably, in 2022-2023, the building underwent a substantial tenant improvement project to convert a second-floor space from office to restaurant use, including the buildout of restrooms, dining areas, and kitchen facilities, at a cost of approximately $315,591.

This project has been accompanied by multiple related permits for fire suppression system installations, plumbing work, and electrical connections, most recently including rooftop deck compliance work valued at $12,000 in August 2023. The building has experienced ongoing regulatory scrutiny related to the rooftop deck, with active building violations as of July 2023 regarding unauthorized deck size and installation, following earlier complaints in 2013 and 2022 about unpermitted construction. Recent construction activities have generated resident complaints about early morning work hours, though these issues were resolved promptly in June 2023.

The property has also undergone various infrastructure improvements, including bathroom renovations for accessibility, reroofing work completed in late 2021, and multiple gas fireplace installations in 2023. Historical records indicate past regulatory matters including a 2009 complaint about blocked exits (deemed without merit) and a 2010 issue with fire extinguishers that was promptly corrected. The building's most recent modifications appear to focus on both residential and commercial improvements, with particular attention to maintaining compliance with city regulations regarding building additions and fire safety systems.
