3301-3303 Fillmore St, San Francisco, CA 94123

The property at 3301-3303 Fillmore Street is a 5-unit mixed-use building constructed in 1900, currently owned by the Norton Family Trust. The building was recently converted from retail to educational use (Mathnasium tutoring center) in 2019, with associated improvements including an electrical sign installation and occupancy revision to accommodate 30 students.

The property has undergone significant renovations over the years, including major work in 2009-2010 involving comprehensive plumbing, electrical, and interior updates, such as kitchen and bathroom renovations across multiple floors, window replacements, and complete electrical system upgrades to 400 amps with dedicated meters for each unit. The building has experienced several fire safety-related incidents and violations, particularly between 2006 and 2020, including issues with alarm systems, sprinkler systems, and multiple fire code violations in June 2020, though these were subsequently corrected or abated.

More recently, in early 2025, there have been multiple open complaints related to public health and safety, including noise, environmental health concerns, and garbage maintenance issues. The property's maintenance history shows regular upkeep, including street space and sidewalk repairs in 2009, though the volume of recent 311 calls suggests ongoing concerns with property maintenance and neighborhood interactions.
