The 15-unit, 4-story multi-family residential building at 1445 Mason Street in Nob Hill, built in 1913, is currently owned by 1445 Mason G1 Lp and has undergone significant safety and modernization improvements in recent years. Most notably, the building completed its mandatory soft-story retrofit as a Tier 3 property, demonstrating compliance with seismic safety requirements. The building has received substantial fire safety upgrades, including recent work in 2021 to install wireless interior low-frequency sounders in sleeping areas and a 2023 violation related to sprinkler maintenance that was subsequently abated.
Recent maintenance work has included dry rot repairs (2020), bay window repairs (2021), and a complete reroofing (2020), while several units (14, 15, and 16) have received bathroom and kitchen renovations. The building's safety systems have been a recurring focus, with multiple fire alarm and sprinkler system inspections and updates between 2018 and 2023. There have been several fire-related complaints over the years, with the most recent violation in September 2023 related to sprinkler maintenance, though this issue was later resolved.
A recent inspection in March 2024 resulted in multiple citations that were promptly addressed by August 2024, including issues with fire escape ladders, fire extinguisher maintenance, and gas utility shutoff tools. The building's history shows regular maintenance and upgrading of individual units, including electrical work, plumbing improvements, and unit conversions, particularly evident in the renovation of Units 14, 15, and 16, and the earlier work in Unit 5. The property has a history of various maintenance and compliance issues, including a 2011 lead paint violation that was resolved in 2012, and past complaints regarding illegal kitchen modifications, which were addressed promptly.
