1150 Union St, San Francisco, CA 94109

1150 Union Street is a 9-story, 51-unit multi-family residential building constructed in 1930 in the Russian Hill neighborhood, currently owned by V & L Union Lp. The property has undergone various significant improvements over recent years, with particular attention to fire safety systems. Most notably, from 2019 to 2024, the building has seen substantial fire safety system upgrades including the replacement of the fire alarm panel, installation of new smoke detectors and pull stations, replacement of the fire pump and sprinkler system components, and implementation of evacuation maps.

Despite these improvements, the building has experienced recurring fire safety violations, with the most recent violations in 2024 related to the sprinkler/standpipe systems and sleeping area requirements. The building's maintenance history shows regular upkeep, including a 2018 boiler replacement and a 2017 kitchen and bathroom remodel in unit #706. However, there have been several concerning incidents and complaints.

In 2019, there was a power outage affecting half the building, including elevators and stairwell lighting, which residents indicated was not an isolated incident. More recently, in 2023-2024, the building experienced water damage issues (complaint filed July 2023) and underwent multiple repairs related to building systems and safety requirements. The property has a documented history of elevator problems, with multiple incidents of trapped passengers recorded as false alarm responses by the fire department, and has received attention from housing inspection services for various code compliance matters, including a 2019 investigation into carbon monoxide and smoke detector compliance.
