1849 Larkin St, San Francisco, CA 94109

The 6-unit, 3-story multi-family residential building at 1849 Larkin Street in Nob Hill, owned by Thomas Ong and Betty Ong Szet, has undergone several significant improvements since its construction in 1910. Most recently, in July 2023, the building received an upgrade to its fire alarm system to comply with San Francisco Fire Code requirements, following a similar electrical modification completed in April 2023 that included installing low-frequency sounders in sleeping areas for enhanced safety.

The building has also addressed important structural concerns, completing mandatory seismic soft-story upgrades in 2016, and obtaining a Certificate of Final Completion (CFC). Other notable improvements include a reroofing project in 2018 and substantial interior improvements to a retail space in 2014, which included comprehensive electrical and plumbing work, though some of these permits ultimately expired. The building's maintenance and safety record shows regular attention to necessary updates, particularly regarding safety systems.

While there have been two routine housing inspections (in 1999 and 2003), no significant violations or concerns were noted. A recent cluster of 311 calls from August to December 2024 primarily related to parking enforcement issues and sidewalk cleanliness matters outside the building, as well as some garbage and debris complaints, though these appear to be more related to street-level conditions rather than directly indicating problems with the building itself. The property has maintained compliance with fire safety requirements, with no merit found in a 2014 fire alarm system complaint, marking it as a building that has proactively addressed both safety and structural requirements, particularly focusing on modernizing its fire safety systems and complying with seismic retrofit mandates.
