544 Guerrero St, San Francisco, CA 94110

The 6-unit apartment building at 544 Guerrero Street, built in 1925 and located in Mission Dolores, has undergone several significant safety upgrades over the past decade. Most recently, in early 2023 and continuing into 2024, the building received comprehensive fire alarm system upgrades costing approximately $28,090 to comply with current fire code requirements, including the installation of low-frequency sounders in all living areas and bedrooms. In 2014, the building completed a mandatory soft-story retrofit as a Tier 3 property, ensuring improved seismic safety.

The building has experienced several maintenance and safety-related issues over its history, particularly noted in 2002-2005 when multiple violations were documented regarding egress obstructions, handrail repairs, and stair conditions, though these violations were subsequently abated. More recent complaints from 2023 focused on general maintenance, peeling exterior paint, and improper storage, all of which have been resolved. The building's electrical systems have been regularly maintained, with significant upgrades completed in 2005 including the installation of new 60-amp subpanels across all floors.

Historical records show previous concerns about fire safety, including a 2011 issue with the alarm panel and a 2005 complaint regarding inadequate rear stair lighting and smoke detectors, though these have been addressed through subsequent upgrades. The property has experienced two fire-related incidents on record, both of which were false alarms with no injuries reported. Recent 311 calls (2024-2025) primarily relate to street-level issues outside the building, such as debris and encampments, rather than building-specific concerns. The current owner, 544 Guerrero Street LLC, has maintained focus on compliance and safety improvements, as demonstrated by the recent fire system upgrades and historical adherence to mandatory retrofitting requirements.
