371 Guerrero St, San Francisco, CA 94103

The 4-unit, 2-story multi-family residential building at 371 Guerrero Street in Mission Dolores, owned by Marchi & Smith Family Trust, has undergone significant infrastructure improvements since its construction in 1939. Most notably, in late 2024, the building completed fire alarm system upgrades to comply with current safety standards, including installation of low-frequency sounders in sleeping areas and compatibility updates to the fire alarm control panel.

The building has received substantial mechanical upgrades over the past decade, including a comprehensive repiping of the plumbing system in 2011, house trap replacement in 2009, and multiple wall furnace installations and replacements between 2007-2008. The property has maintained responsiveness to safety and compliance issues, as evidenced by prompt remediation of violations from a 2011 routine inspection, which included work on the central alarm system, fire extinguishers, and self-closing exterior doors.

While there have been several quality-of-life issues reported through 311 calls in recent years, including graffiti (2023), sidewalk defects (2023), and waste removal needs, these cases were generally addressed through normal municipal processes. The building's maintenance history shows regular attention to infrastructure needs, though some permits from earlier years, such as a 1999 reroofing project, are listed as expired. The most recent building improvements, particularly the fire safety upgrades, demonstrate ongoing commitment to maintaining current safety standards, though the building's age and history suggest regular maintenance and updates have been necessary to address its infrastructure needs over time.
