2762-2764 Filbert St, San Francisco, CA 94123

This two-story, three-unit multi-family residential building located at 2762-2764 Filbert Street in Cow Hollow was built in 1922 and is currently owned by the Victor Bertolozzi Living Trust. The property has undergone significant renovations since 2022, including major foundation work ($98,000), comprehensive interior remodeling ($1.5 million) across all floors, and the addition of a new roof deck. Recent improvements include the installation of a fire sprinkler system ($39,502) with related underground service, and comprehensive electrical upgrades featuring a new 400-amp panel with four meter stack.

The building now features modern amenities such as radiant heating, a heat pump system, and updated plumbing infrastructure servicing multiple bathrooms and kitchens. The renovation process has generated several construction-related complaints, particularly regarding unauthorized work and sidewalk/blockage issues, though most have been resolved through enforcement actions or permit adjustments. Notably, there were past concerns in 2015 about unpermitted window replacements and in-law unit conversion attempts.

Recent building permits issued throughout 2024-2025 indicate the property is nearing completion of its major upgrades, though some permits such as the 2023 plumbing permit for extensive bathroom and kitchen work have expired. The property has maintained active communication with city agencies regarding construction impacts, as evidenced by multiple 311 calls and prompt responses from city departments. The renovation work has drawn attention to historical resource considerations, with at least one Historic Resource Assessment (HRA) conducted. The building's modernization efforts have focused on maintaining safety standards through updates like the fire sprinkler installation while dramatically improving the unit's overall infrastructure, as evidenced by the comprehensive nature of the electrical, plumbing, and mechanical system upgrades.
