400 Anza St, San Francisco, CA 94118

The 21-unit, three-story apartment building at 400 Anza Street in San Francisco's Lone Mountain neighborhood, owned by 400 Anza Partners LLC, has undergone significant improvements and faced several safety-related issues since its construction in 1975. Major recent upgrades include the 2016 addition of five new dwelling units, legalization of a fourth floor unit, and completion of mandatory soft-story retrofit work.

The building's fire safety systems have received substantial attention, with the installation of comprehensive sprinkler systems in 2018 (garage and first floor) and fire alarm system upgrades in 2019, including new monitoring capabilities and device compatibility improvements. Despite these improvements, the building has experienced recurring safety and maintenance issues, as evidenced by several fire safety complaints between 2016 and 2024 regarding extinguishers, sprinkler systems, exit maintenance, and a recent sleeping area requirement violation in December 2023. Historical maintenance problems include water damage incidents in 2008, reports of mold and bathroom issues in 2015, and tenant complaints about aging carpets and maintenance concerns dating back to 1997.

The property has also undergone various unit improvements, including electrical panel replacements, bathroom fan installations, and general unit modernization work in 2018. While the building has had multiple fire-related incidents recorded (including cooking fires and alarm activations), none resulted in civilian injuries. The property maintains a record of addressing most violations and complaints, with many being marked as "Condition Corrected" or "Abated," though some issues remain concerning in terms of pattern and frequency.
