1637-1647 Larkin St, San Francisco, CA 94109

The 6-unit, 3-story apartment building at 1637-1647 Larkin Street in Nob Hill, built in 1907, has undergone several significant structural improvements over the years, most notably completing a seismic soft-story retrofit in 2017 at a cost of $70,000, which has brought the building into compliance with current safety standards. The most recent maintenance work was performed in October 2024, addressing minor dry rot repairs to the back stairs at a cost of $3,000.

Historical records from 2001 show a cluster of violations related to building safety and fire requirements, including issues with stairs, door closures, fire extinguisher maintenance, and combustible storage concerns; however, all of these violations were promptly abated within approximately one month. The building's maintenance history also includes a reroofing project in 2006. Recent activity around the property predominantly involves external street and parking issues, with multiple reports of driveway blocking between 2021 and 2024, though these are not directly related to the building's condition.

There have been two complaints about unauthorized construction work, one in 2016 regarding debris removal practices and another in 2018 about working without permits; both complaints were resolved. The most recent 311 calls from 2023-2024 primarily concern street maintenance and parking issues rather than building-specific problems. The property has maintained its compliance with major safety requirements, including the successful completion of the seismic retrofit program (Tier 3) with a Certificate of Final Completion issued.
