1166 Pine St, San Francisco, CA 94109

The four-story, 12-unit multi-family residential building at 1166 Pine Street, owned by Larkin David G & Tang Trang, was constructed in 1921 and has experienced several significant maintenance and safety issues over its history. Most concerning are recent fire safety violations, with the most recent documented in July 2023 regarding sprinkler system maintenance, and previous violations in 2022-2020 related to multiple fire code compliance issues. The building's infrastructure has undergone several notable improvements, including a complete plumbing upgrade in 2014 with the installation of new bathtubs, sinks, and sewer pipes, as well as the replacement of the steam heating boiler in 2009.

The building has a documented history of staircase safety concerns, including repairs to wood rear stairs in 2010 and historical issues with dry rot in 1993 and 1996. A significant common area complaint was filed in April 2024, though it was abated within two weeks. The property's maintenance history shows regular attention to major systems, including reroofing work in 2003 and the installation of solar panels for hot water in 1984 (though this permit is now expired).

The building has undergone multiple routine housing inspections over the years, with varying degrees of compliance, including issues with fire escape maintenance and gas utility shutoff tools as recently as 2024. Historical complaints from the late 1990s/early 2000s indicate past concerns about electrical systems and security features such as mailboxes, though many of these issues appear to have been resolved. The building's location in downtown San Francisco has also experienced various street-related issues, as evidenced by multiple 311 calls in 2024 regarding garbage, debris, and encampments in the vicinity, though these external factors do not directly reflect on the building's internal conditions.
