6439-6441 California St, San Francisco, CA 94121

The property at 6439-6441 California Street is a two-story mixed-use building constructed in 1911, containing two residential units and ground-floor commercial space. The building has undergone significant improvements in recent years, including a change of use from limited coffee shop/retail to a non-formula retail restaurant in 2018, comprehensive reroofing in 2020, installation of a fire suppression system in 2022, and various plumbing and electrical upgrades. Notable structural improvements include the replacement of a wooden staircase with a steel spiral stair in 2019 and various bathroom and kitchen remodels totaling approximately $130,000 in permitted work between 2016 and 2022.

The building currently faces several active concerns that warrant attention. Most pressing is an active complaint from March 2023 regarding possible unpermitted work and construction noise, as well as a vacant commercial storefront violation related to monthly monitoring fees. The property has a history of maintenance issues, including heating system problems, electrical concerns, and plumbing problems, though many of these were addressed through subsequent repairs and upgrades.

Recent infrastructure maintenance has included sidewalk repairs in 2022 and plumbing work in 2020-21. The building experienced a sewage backup in December 2023, which was promptly resolved. Past violations from 2010 included issues with heating systems and electrical fixtures, which were subsequently abated. The property's commercial space has undergone various transformations over the years, including controversies over backyard use and smoking, though most recent commercial modifications have been properly permitted.
