665-669 Minna St, San Francisco, CA 94103

The 665-669 Minna Street property is a three-story, six-unit multi-family residential building located in San Francisco's South of Market neighborhood. Built in 1906, this building has undergone numerous modifications and faced several compliance issues over recent years. The most significant period of concern occurred in late 2016, when multiple building violations were documented, including issues with electrical systems, fire safety, and illegal basement construction work.

These violations resulted in a series of completed repairs by April 2017, though some concerns regarding basement modifications persisted through subsequent years. The building underwent a significant plumbing upgrade in 2019-2021 with the installation of six tankless water heaters and associated electrical work, though some related permits were canceled or marked as expired. More recent records show that the building achieved soft-story retrofit compliance (Tier 4) status with work completed and a Certificate of Final Completion issued. There have been several complaints and violations related to fire safety, with violations recorded in both 2016 and 2020, including issues with fire extinguishers, alarm systems, and required permits.

The property has experienced recurring concerns with unauthorized short-term rentals, with violations recorded and subsequently abated in 2014 and 2020. Most recently, in early 2025, there have been multiple 311 calls regarding the area surrounding the building, including reports of encampments and sanitation issues, though these relate more to the neighborhood condition than the building itself. The property has also faced maintenance challenges, with complaints about noise disturbances during construction work in 2019 and concerns about exposed wiring in 2020, which were marked as not active. The building's ownership has undertaken various improvement projects over the years, including attempted additions of accessory dwelling units and multiple infrastructure upgrades, though many permits for these works have either been canceled or withdrawn.
