450 Green St, San Francisco, CA 94133

450 Green Street is a three-story, multi-family residential building constructed in 1907 in the Telegraph Hill neighborhood, currently owned by SF Green LLC and containing 4 units. The property has experienced several significant issues in recent years, most notably including multiple active and expired violations and complaints regarding unauthorized construction and modifications. Of particular concern is an active complaint from 2021 regarding unpermitted awnings, and previous compliance issues related to unauthorized units and facade alterations.

In 2015, a major renovation effort was undertaken to legalize an unauthorized unit and bring various features to code, though this work generated subsequent complaints about unpermitted construction. The building has also faced multiple safety-related violations, including several fire safety concerns in 2005 (all of which were abated), and more recent issues in 2016 regarding dangerous habitability, including exposed wiring and unpermitted work. Recent building improvements have primarily focused on obtaining final inspections for previously approved work, with multiple permit applications in July 2024 indicating completion of earlier approved projects.

The property has undergone various unit improvements over the years, including kitchen and bathroom remodels, window replacements, and flooring upgrades, though some of this work has been undertaken without proper permits, as evidenced by multiple complaints. The building has maintained active compliance efforts, with several permits being processed or completed in recent years, including remediation of past violations. The property has experienced persistent exterior maintenance issues, as evidenced by multiple 311 calls in 2024 regarding garbage and debris, though these are primarily related to street cleaning rather than direct building conditions. A tenant buyout occurred in late 2021 for $15,000, affecting one tenant at the Varennes Street address.
