1645 Golden Gate Ave, San Francisco, CA 94115

1645 Golden Gate Avenue is a 3-story, 6-unit multi-family residential building constructed in 1913, currently owned by City Ring 2 LLC. The property has undergone several significant upgrades in recent years, most notably a mandatory soft-story retrofit completed in March 2024 and a major fire alarm system upgrade issued in June 2024, which includes the installation of low-frequency horns and replacement of fire alarm devices. The building has a documented history of improvements, including substantial unit renovations in 2015-2016, with Units 1 and 4 receiving kitchen and bathroom remodels, and electrical upgrades including replacement of Federal Pacific panels and installation of new electrical systems.

The building has experienced several maintenance and safety concerns over its history. In 2009, a cluster of violations was documented, including issues with stairs, ceilings, interior surfaces, and security requirements, all of which were abated by October 2009. More recently, a complaint was filed in November 2020 regarding the building's status as a soft-story structure, though this appears to have been addressed with the completion of the retrofit in 2024.

The property has undergone regular routine safety inspections, with the last one conducted in 2019. While there have been some exterior issues reported through 311 calls and complaints, such as graffiti (2015), a water leak (2014), and various street-related concerns, these have generally been resolved promptly and do not appear to indicate any ongoing structural or safety concerns. A fire incident was recorded in 2017, though it was determined to be a false alarm with no civilian injuries.
