1083-1099 Union St, San Francisco, CA 94133

The 6-unit, 3-story apartment building at 1083-1099 Union St in Russian Hill, built in 1912 and currently owned by Woo Fmly Tr, has undergone several significant improvements and faced multiple maintenance challenges over its recent history. The building completed a mandatory soft-story retrofit in 2018 at a cost of $38,000, demonstrating compliance with seismic safety requirements.

Major mechanical upgrades include the replacement of a low-pressure steam boiler in 2010 and a backflow device in 2015. The property had a cluster of building violations and complaints in late 2009 through early 2010, primarily concerning heat-related issues, window maintenance, and fire safety systems, all of which were resolved by November 2010. Recent years have shown improved maintenance, though there has been a notable pattern of parking-related issues in the vicinity, with multiple 311 calls in 2023-2024 regarding driveway blockages and sidewalk access.

The building's fire safety systems experienced two alarm incidents in recent years, though neither resulted in any injuries or fires. The most recent building inspection records suggest no active violations or complaints, indicating improved property management standards. The property's historical records show regular compliance with routine inspections dating back to 1999-2005, and all known code violations and complaints have been addressed and resolved according to official records.
