735-767 Mason St, San Francisco, CA 94108

The four-story, 17-unit apartment building at 735-767 Mason Street, built in 1908, has undergone several significant structural and safety improvements over the past decade, most notably a complete soft-story retrofit completed in 2015 at a cost of $85,000, bringing the building into compliance with San Francisco's mandatory seismic retrofit requirements. The building's maintenance history shows attention to basic upkeep, including a $23,600 reroofing project completed in 2016 and the installation of new electrical grading in the foundation during the same year.

Recent concerns about building safety and habitability have surfaced, with the most current active complaint filed in March 2024 regarding common areas. A notable incident occurred in July 2019 involving hazardous materials, specifically paint stored near the furnace in the basement.

The building experienced significant maintenance issues in 2012-2013, including multiple complaints about non-functional heaters, mold in bathrooms, and various code violations, though most of these issues appear to have been addressed by 2014. Several historical violations from 2000-2001 were documented, including problems with fire extinguishers and damaged stairs, but these were also abated. The building's owner, Nancy Mar Tr, has completed all required soft-story retrofit work and obtained the necessary certificates of final completion, demonstrating compliance with critical safety requirements.
