180-190 San Carlos St, San Francisco, CA 94110

The three-story multi-family residential building at 180-190 San Carlos Street in the Inner Mission, owned by Cheung Wing C & Sioe D, is a 6-unit apartment complex constructed in 1906. The property has undergone several significant safety improvements in recent years, most notably completing the mandatory seismic retrofit program in 2022 at a cost of $92,000, for which they received a Certificate of Final Completion.

In late 2021, the building faced violations related to the Soft Story Program, including failure to complete required work and associated fines, though these were ultimately abated in January 2024. The building has experienced recurring issues with fire safety systems, including violations and complaints regarding sprinkler systems, standpipes, and extinguishers between 2018-2022, though most were marked as "Condition Corrected" or "No Merit." The property has been the subject of multiple 311 calls in recent months, primarily between October 2024 and January 2025, regarding garbage and debris, though these appear to be street cleaning matters rather than building-specific issues.

Historical fire safety violations from 2019 were recorded related to the sprinkler system service and alarm maintenance, but these were subsequently abated. The building's fire alarm systems have experienced occasional malfunctions, including one incident that triggered a false alarm. While there have been various fire safety concerns documented over the years, the most recent notable improvement was the completion of the seismic retrofit requirements, bringing the building into compliance with current earthquake safety standards, which is a significant enhancement to resident safety.
