1100 Jackson St, San Francisco, CA 94133

The 16-unit, 4-story multi-family residential building at 1100 Jackson Street in Nob Hill, built in 1909, has undergone significant improvements and faced various challenges over the years. Most notably, the building completed its mandatory fire safety upgrades in 2021 with the installation of a new fire alarm system including low-frequency horns, smoke detectors, and other safety features. A major soft-story retrofit was completed in 2016 with the installation of a Simpson moment frame over the garage door, demonstrating compliance with San Francisco earthquake safety requirements.

The building has undergone substantial unit renovations, including comprehensive remodels of units 4, 9, 10, and 11 between 2003 and 2013, which included kitchen and bathroom upgrades, electrical rewiring, and plumbing improvements. The property has maintained active fire safety compliance, with regular inspections and corrections, though a 2019 violation related to sprinkler service was noted. Historical issues from 2002 highlighted various maintenance concerns that have since been addressed, including plumbing leaks, damaged surfaces, and pest problems, all of which were officially abated by May 2002. Recent inspection and maintenance records show ongoing attention to building systems and safety features, including electrical upgrades such as the installation of 8 exit signs in 2018.

The building has experienced typical urban incidents, including elevator rescues and kitchen-related emergencies, though none have resulted in civilian injuries. Current maintenance records indicate regular upkeep, with recent fire alarm system maintenance in 2023 showing continued attention to safety systems. The building's owners, 1100 Jackson Assoc LLC, have demonstrated commitment to addressing both immediate and long-term building safety and habitability requirements, as evidenced by the completion of major structural improvements and consistent response to inspection findings. The property's most recent activities primarily involve routine safety system maintenance and responses to normal building operations, with no current active violations or major outstanding issues.
