1470 9th Ave, San Francisco, CA 94122

The 12-unit, 3-story apartment building at 1470 9th Avenue in the Inner Sunset, owned by Tan Trust, has undergone significant improvements and modifications since its construction in 1963, with the most substantial work occurring between 2017-2020. Notably, the building added two accessory dwelling units (ADUs) in 2017 as part of a $180,000 project, followed by comprehensive fire safety upgrades including a new NFPA 13 fire sprinkler system ($32,712) throughout the ground floor in 2019 and fire alarm system modifications in 2020 ($15,000).

The building has completed its mandatory soft-story retrofit (Tier 3) and met fire safety requirements through several inspections and upgrades, including recent work in December 2023 for sprinkler maintenance and boiler permit renewals. The property has experienced some maintenance challenges over the years, including a notable heating complaint in 2016 regarding insufficient temperatures in one unit during winter, and several historical boiler permit issues that have required attention between 2001 and 2020.

While there have been multiple fire safety complaints registered between 2005 and 2023, these have generally been resolved quickly, with most being determined to have "No Merit" or were promptly corrected. Recent activity suggests ongoing maintenance and compliance efforts, as evidenced by the December 2023 renewal of sprinkler and plumbing permits. The building has also experienced periodic issues with parking violations and sidewalk maintenance, with several complaints about blocking driveways between 2016-2024, though these are external to the building's operations.
