1642 Larkin St, San Francisco, CA 94109

1642 Larkin Street is a 3-story, 12-unit multi-family residential building located in Nob Hill, owned by Mecham Family LP and constructed in 1922. The building has undergone several significant safety and infrastructure improvements in recent years, including a completed soft-story retrofit in 2017 (with plywood shear walls and steel frames added at the ground floor), a comprehensive fire alarm system upgrade in 2023 to meet fire code requirements (including low-frequency sounders and new fire panel), and the installation of individual subpanels in most units in 2018 to improve electrical service. The building has an active fire safety maintenance record, with three fire alarm system complaints between 2020-2022 that were corrected, and three carbon monoxide-related incidents (two in 2020, with no injuries reported).

Historical maintenance records show consistent upkeep, including reroofing projects in 1989 and 2015, and temporary shoring work in 2004. The building experienced multiple fire code violations in 2001 related to fire extinguishers and fire proofing, all of which were abated by June 2001. A routine inspection in 2009 resulted in violations for self-closing exterior doors and hot water heater seismic bracing, which were also resolved.

Recently, there have been some infrastructure challenges, including two sewer backup incidents in 2022 and multiple parking enforcement calls for blocking driveways between 2022-2024. The property is classified as Tier 3 in the Soft Story program, with all required work completed and a Certificate of Final Completion issued. The most recent building improvements and active maintenance of fire safety systems suggest a committed approach to maintaining building safety standards.
