3775 Fillmore St, San Francisco, CA 94123

The 12-unit, 3-story apartment building at 3775 Fillmore Street, owned by 3775 Fillmore LLC, was constructed in 1928 and has undergone several significant improvements over the years. Most notably, the building completed its mandatory soft-story retrofit program in 2021 after initially securing permits in 2018, which included engineering work valued at approximately $96,000.

The building's seismic safety infrastructure was previously reinforced in 1992 with mudsill bolting and epoxy work. Recent maintenance records from 2024 indicate ongoing challenges with the building's fire safety systems, including multiple fire alarm system and fire extinguisher violations that were corrected between May and September 2024, though these suggest persistent issues with the building's fire safety equipment. The building's mechanical systems have seen substantial upgrades, including the installation of a new steam boiler, backflow device, hot water heater, and storage tank in 2017 (though a boiler permit violation was recorded in January 2022), as well as unit-specific improvements such as the 2007 renovation of Unit #3's kitchen and bathroom.

Historical records show various infrastructure improvements including reroofing in 2002, ground-level parking upgrades (also 2002), and several plumbing and electrical upgrades. Recent 311 calls from late 2024 indicate typical urban maintenance issues outside the property, including reports of flooding, tree maintenance needs, and pavement defects on Fillmore Street, though these are municipal infrastructure issues rather than building-specific problems. The building's fire safety history shows a pattern of false alarms and system malfunctions, though no civilian injuries have been recorded in association with these events.
