1661 Leavenworth St, San Francisco, CA 94109

The three-story, six-unit multi-family residential building at 1661 Leavenworth Street in Nob Hill, owned by Valentino Trust, has undergone significant improvements and faced challenges since its construction in 1913. Most notably, the building completed mandatory soft-story seismic retrofitting in 2017 (Tier 3) at a cost of $40,000, demonstrating compliance with current safety standards. Recent upgrades include window replacements in 2019, involving installation of aluminum-clad wood framed windows on the front facade and vinyl sashes on interior windows, with a cost of $9,000.

The building has experienced periodic maintenance issues, as evidenced by multiple complaints and violations in 2011 related to fire safety, including egress obstruction, combustible storage, and inadequate lighting, all of which were abated by July 2011. There were also interior condition issues noted in 2009 regarding the lobby area, though these were resolved within a month. More recent history shows some recurring maintenance challenges, particularly with water infiltration and exterior features.

In 2017, there were multiple complaints about back porch leaks, which prompted inspections and further work. The building has undergone various maintenance and repair work, including plumbing updates with rain leader pipe replacement in 2017, and repairs following a Notice of Violation in March 2017. While there have been no active building violations since 2017, recent inspections and 311 calls (from 2020-2024) have primarily related to street-level issues outside the building proper, such as sidewalk cleaning and graffiti on nearby bike racks. The property has maintained compliance with major safety requirements, as evidenced by the completed soft-story retrofit, and recent building permits indicate ongoing maintenance and improvements to keep the property up to date.
