Augrented Insights Report

The 13-unit, 3-story multi-family residential building at 3643-3645 Buchanan Street in the Marina neighborhood, owned by Cohen Menahem M Trustee, has undergone several significant structural and safety improvements since its construction in 1973. The most substantial recent work was the completion of a mandatory soft-story retrofit in 2018, which included additional ADA bathroom upgrades, demonstrating compliance with seismic safety requirements (Tier 4 status: Work Complete, CFC Issued).

The building's foundation history includes a serious incident in 2004 when the north property line foundation was undermined by excavation at a neighboring property, requiring remedial work to fill voids in the foundation, which was completed by February 2005. The property has experienced recurring fire safety inspections and violations between 2016-2024, with issues ranging from combustible materials and alarm systems to extinguisher maintenance and hazardous materials, though most have been promptly corrected.

Recent 311 calls indicate ongoing maintenance needs, including an open sidewalk defect case from November 2024 involving tree root damage, and various sidewalk cleaning issues in 2021-2024. While there is one active security violation from 2000 regarding security requirements, the building has generally maintained compliance with major safety requirements, though some historical violations from 2004-2006 related to foundation work and egress obstruction have been resolved.
