570 Union St, San Francisco, CA 94133

570 Union Street is a 3-story, 17-unit multi-family residential building constructed in 1965, currently owned by Rosano Properties LLC. The property has undergone several significant improvements in recent years, including an ongoing window and door replacement project (initiated September 2024) costing $147,000, and a voluntary fire alarm system upgrade completed in September 2023. The building has experienced recurring fire safety system-related issues, with multiple violations and complaints regarding alarm systems, sprinkler systems, and sleeping area requirements between 2014 and 2024.

Most recently, in July 2024, a violation was issued regarding the alarm system maintenance, while an open violation from November 2023 pertains to sleeping area requirements. Historical fire safety concerns were addressed promptly, with past violations for blocked exits (2017), and various system-related issues being corrected or found as having no merit. The building's maintenance history shows attention to basic infrastructure, including a reroofing project recorded in 1992, though this permit has since expired.

During its history, the property has undergone three routine housing inspections (2000, 2005, and 2007), with all issues being resolved. Recent 311 calls from 2024 primarily involve external matters such as sidewalk blockages, waste issues, and graffiti removal, rather than building-specific concerns. Two carbon monoxide incidents and three false alarm/fire call incidents were recorded by fire services, all resulting in no civilian injuries. The building's management has shown a pattern of addressing violations and complaints, with many issues being promptly corrected or resolved, though some recent violations related to fire safety systems remain open or were only recently abated.
