1901-1909 Larkin St, San Francisco, CA 94109

The three-story multi-family residential building at 1901-1909 Larkin Street in Nob Hill, owned by the Vickie Y Ho Revocable Trust, was constructed in 1906 and contains five units. The property has undergone several significant structural improvements, most notably completing a mandatory Soft Story retrofit in 2023 (designated as Tier 4), which included both commercial and residential portions.

Recent building improvements from 2023 involved accessibility modifications to the commercial space and structural revisions. The building has a history of compliance with various safety requirements, including electrical system upgrades in 2011 to a 300A service, and multiple renovation projects including bathroom updates, commercial space conversions, and ADA improvements. Historical records indicate some past maintenance issues, including lead paint concerns (2001) that were promptly addressed, and a vacant commercial storefront violation in 2017 that was resolved.

Recent 311 calls (2024-2025) show ongoing maintenance of the surrounding area, primarily involving street cleaning and debris removal, though these issues are external to the building itself. The commercial portion of the building was previously converted to accommodate an acupuncture therapy medical office in 2013, and various plumbing and electrical improvements have been documented over the years, including bathroom renovations and mechanical upgrades. The property's compliance with the Soft Story program, with work now complete and a Certificate of Final Completion issued, addresses one of the most critical safety requirements for older buildings in San Francisco.
