1150 Hyde St, San Francisco, CA 94109

The 6-unit, 3-story multi-family residential building at 1150 Hyde Street in Nob Hill, owned by Grant Kwok, has undergone several significant infrastructure improvements since its construction in 1912. Most notably, the building completed its mandatory soft-story retrofit in 2020, which included a $40,000 seismic improvement to address earthquake safety concerns. Recent maintenance work includes a completed boiler installation in 2016, and previous plumbing improvements in 2008 involved replacing the house trap and sewer repairs.

The building has shown periodic concerns with basic systems and habitability standards, particularly between 1998-2009, with documented issues including inadequate heat, plumbing problems, security concerns, and various maintenance violations. These earlier problems led to multiple housing inspection cases, though all were eventually resolved. The building's permit history shows consistent attention to maintenance and upgrading systems, including electrical improvements in 2007 for garage lighting and emergency systems, door replacements, and various interior repairs.

Several code enforcement cases from 2007-2009 required attention to issues such as a malfunctioning intercom system, broken windows, and smoke detector installation. The most recent violations were addressed in October 2020, and there have been no active housing complaints since. Recent 311 calls primarily relate to external street maintenance issues rather than building-specific problems, suggesting improved internal conditions. The building's completed soft-story retrofit, which obtained its Certificate of Final Completion (CFC), indicates compliance with current seismic safety requirements, though it was noted that there were temporary issues with monitoring fees and posted earthquake warning placards in early 2020 that were subsequently resolved.
