52 Sanchez St, San Francisco, CA 94114

The 12-unit, 4-story multi-family residential building at 52 Sanchez Street in Duboce Triangle, owned by Dere Investment Associates, has undergone several significant upgrades and faced various challenges since its construction in 1907. Most notably, the building completed mandatory soft-story seismic upgrades in 2016-2017, involving additional footings and structure reinforcement, achieving "Work Complete, CFC Issued" status as a Tier 4 property. A major fire incident in 2004 required comprehensive repairs including kitchen and bathroom replacements, roof work, and electrical system rewiring, costing approximately $300,000.

More recently, in 2022, the building received a new hydronic boiler installation, and various fire safety improvements have been made, including a 2023 correction of combustible materials issues and previous violations in 2019 regarding alarm systems and extinguishers. The building's history includes a series of routine inspections and some concerning incidents in the early 2000s, particularly multiple violations related to fire safety, smoke detection, and building maintenance in August-October 2002, all of which were subsequently abated. Electrical system upgrades were performed in 2004-2005, including rewiring of multiple units and kitchen installations.

Recent housing inspections in 2016 and 2023, though not revealing any ongoing concerns, indicate regular oversight of building conditions. The property has maintained relatively active response to fire safety issues, with various violations being promptly addressed through repairs or corrections, including a significant focus on maintaining fire alarm systems and extinguishers. The building's recent history shows ongoing maintenance and upgrading of essential systems, though there have been occasional issues requiring correction, such as a 2023 combustible materials complaint and previous fire alarm system concerns.
