2135 Sacramento St, San Francisco, CA 94109

The 36-unit, 5-story apartment building at 2135 Sacramento Street in Pacific Heights, built in 1900 and currently owned by Golden Century LP, has undergone significant maintenance and improvements over the years. Most recently, in 2024 and 2023, the building has seen window replacements in units 407 and others, demonstrating ongoing efforts to improve energy efficiency. However, the property has experienced serious safety concerns, particularly in May 2023 when multiple gas leak and carbon monoxide detector incidents were reported on the 5th floor, including problematic handling of a carbon monoxide alarm situation involving the boiler system.

These incidents occurred shortly before the building's elevator permit expired, leading to additional complaints. The building has also faced various violations, all of which were officially abated by August 2017, including issues with security, smoke detection, fire proofing, and combustible storage. More recent violations include a December 2023 sleeping area requirement violation that remains open.

The building's maintenance history includes systematic window replacements (2003, 2004, 2023-2024), boiler replacements in 2014-2015, and a seismic upgrade completed in 1998. While there have been several parking enforcement issues recorded in 2024, these are external to the building itself. The property's documented history shows a pattern of both maintenance upgrades and safety concerns that have required attention over the years.
