123-137 Pfeiffer St, San Francisco, CA 94133

The 2-story, 11-unit multi-family residential building at 123-137 Pfeiffer St in Telegraph Hill, owned by Vh & M Associates LP, was constructed in 1900 and has undergone several significant modifications and faced various regulatory challenges over its history. Most notably, the building completed its mandatory soft-story retrofit in 2019, which included the installation of steel moment frames and plywood shear walls at a cost of $180,000, with subsequent revisions to replace wood plywood shear walls with Simpson Strong Walls. The retrofit process was marked by compliance issues, with two notices of violation filed in 2017 and 2019 regarding failure to obtain proper permits, though these violations were ultimately abated in September 2019.

The building has faced recurring maintenance and safety concerns over the years, particularly in 2011 when multiple serious issues were documented, including water intrusion, mold, structural problems, and concerns about an unstable upper walkway. A routine inspection in 2005 revealed several safety concerns that required attention, including emergency exit lighting, handrail requirements, and fire escape accessibility issues, though these were marked as not active by 2019. More recently, the property has experienced multiple sewage backup incidents, as documented in 2020-2022 service calls, with the most recent being in October 2022.

The building underwent reroofing work in 1996 and 1998, though these permits have since expired. The property's compliance history shows a pattern of addressing mandatory safety requirements, as evidenced by the completion of the soft-story retrofit program, and responding to various housing and safety concerns when they arise. While many historical violations have been resolved, the building's recent history suggests continuing challenges with basic infrastructure maintenance, particularly regarding sewer systems, as evidenced by multiple service calls in recent years. The most recent soft-story retrofit completion status is noted as Tier 3 with a Certificate of Final Completion issued.
