422 9th Ave, San Francisco, CA 94118

The 15-unit, 3-story multi-family residential building at 422 9th Avenue, owned by Trinity G2 Holding LLC and constructed in 1966, has experienced several significant maintenance and safety events over its history. Most notably, there is currently a fire alarm system upgrade in progress (2025) involving new devices and low-frequency sounders in sleeping areas, along with associated electrical work. The building has had recurring issues with its fire alarm system, with multiple violations and corrections between 2013 and 2024, suggesting ongoing challenges with fire safety equipment maintenance.

Recent improvements include a domestic boiler replacement in 2019 and a substantial kitchen and bathroom renovation in unit 205 in 2015, though this renovation prompted a complaint in 2015 regarding after-hours construction noise. Historical issues from the 1990s included multiple water-related problems, with roof leaks documented in 1996-1998 and interior water damage complaints. The building has undergone various structural and systems upgrades over the decades, including exterior framing repairs (2003), a street space permit (2003), and multiple roofing projects.

A notable complaint about unauthorized construction work in 2003 was reported, and five fire escape-related violations were documented in 2002, though these were abated by July 2002. More recent maintenance activity includes three consecutive fire safety inspections between 2021 and 2024, with violations issued in 2020 and September 2024. The property has generally complied with routine inspections, including annual housing inspections, though there were significant tenant complaints about water issues and construction work in the mid-1990s. The building's current owners appear to be actively addressing fire safety concerns, as evidenced by the ongoing fire alarm system upgrade and recent boiler replacement, though the frequency of fire system-related complaints suggests this remains an area requiring attention.
