590 Bosworth St, San Francisco, CA 94131

590 Bosworth Street is a mixed-use, three-story building constructed in 2004, currently owned by Dental Properties LLC. The building features one residential unit and commercial space used primarily as a dental office. The property has undergone several significant telecommunications-related modifications, including the recent installation of new T-Mobile antennas in December 2024 (cost: $35,000) and various electrical upgrades to support telecommunications equipment. The building's history includes some concerning safety issues, particularly regarding fire safety systems.

Most recently, in August 2024, violations were issued for alarm systems and fire extinguishers, though these were later abated. Historical fire safety violations from 2019 included issues with emergency lighting, building owner contact postings, and alarm systems. The property experienced construction-related incidents in 2003-2004 involving foundation damage to a neighboring property during renovation work, though these issues were promptly addressed. Recently, starting January 2025, there have been multiple 311 calls regarding the property, primarily related to graffiti and debris on the exterior, with several cases remaining open as of January 2025. The building underwent a vacant storefront violation in early 2023, which was resolved by June 2023.

A tenant buyout was processed in November 2024, involving two tenants and totaling $15,080. In terms of future use, there are ongoing discussions about using both ground and second floors for dental office purposes, with permits indicating the intention to renovate interiors while maintaining existing square footage. The building's earliest records show it was developed as a mixed-use structure with dental office space on the ground and second floors, plus residential units above. The property has undergone various modifications and improvements over the years, including skylight guard installation (2018) and multiple telecommunications system upgrades to support T-Mobile equipment. The history of the property shows a pattern of maintaining commercial dental office space with periodic residential unit changes, though recent issues with vacant storefront enforcement and fire safety violations indicate areas requiring attention.
