171 Guerrero St, San Francisco, CA 94103

The two-story, five-unit multi-family residential building at 171 Guerrero Street, built in 1925, has undergone several significant upgrades and faced recurring safety system challenges over the past two decades. Most recently, in 2024, electrical work has been completed in both Unit 3 and Unit 4, following previous electrical improvements in Unit 1A in 2021. The building has undergone important safety upgrades, including a voluntary seismic retrofit in 2010, a fire alarm system installation and upgrades in 2018, and various roof replacements in 2003 and 1988.

However, there have been persistent fire safety system issues, with violations and complaints regarding alarm systems, sprinklers, and extinguishers recorded in 2024, 2023, 2022, and 2020, though all were corrected upon inspection. The building's history shows attention to structural and safety improvements, including the removal of an unpermitted deck and stair in 2006 for fire safety compliance. A routine housing inspection in 2003 identified several safety concerns, including handrail repairs, roof deck safety, and entrance door reinforcement, all of which were promptly addressed within two months.

More recently, in 2024, there have been multiple reports of driveway blocking incidents requiring parking enforcement, suggesting ongoing challenges with parking management in the area. The building has experienced several false fire alarm incidents and detector activations over the years, though notably, there have been no reported civilian injuries from these events. While the property management has generally addressed violations and maintenance issues, the frequency of fire safety system concerns suggests this remains an area requiring ongoing attention.
