350 Union St, San Francisco, CA 94133

350 Union Street is a 90-unit, 3-story multi-family residential building constructed in 1965 located in Telegraph Hill, currently owned by Trinity G2 Holding LLC. The property has undergone several significant safety and maintenance upgrades in recent years, including a fire alarm system replacement in 2019-2020 ($60,000), the installation of new fire alarm booster panels and circuits in 2020, and most recently, reroofing work scheduled for 2024 ($181,350). The building has experienced recurring fire safety issues, with violations noted for alarm system maintenance and sprinkler service requirements in 2020, and a current open violation from October 2023 regarding sleeping area requirements.

Multiple fire complaints between 2012 and 2023 have been documented, including issues with blocked exits (2016) and hazardous materials (2021), though most were corrected promptly. The building has a history of water-related problems, particularly in 2008 when multiple complaints were filed regarding leaks in the courtyard deck, bathroom water damage, and interior water damage. A 2022 inspection raised concerns about the integrity of an old brick retaining wall on the property's west side.

Recent maintenance issues include electrical work completed in 2020-2021 focusing on exterior outlets and lighting, with ongoing concerns about potentially overgrown trees and property damage (most recently reported in 2024). The property has experienced several pest-related issues, with a rodent/insect infestation reported in December 2024 and previous complaints about bedbugs and bathroom mold in 2015. A cluster of street space permits was issued between 2012-2019, suggesting regular use of public space around the building for various activities.
