3528-3530 Sacramento St, San Francisco, CA 94118

The two-unit residential building at 3528-3530 Sacramento Street in Presidio Heights, owned by Cobbs Revoc Tr, was constructed in 1900 and has undergone several significant renovations and safety upgrades over its lifetime. Most notably, in 2020, the property received an accessibility modification regarding the technical infeasibility of accessing second-floor offices under the accessible business entrance program.

A major remodeling project was completed in 2003-2004, which included the installation of an elevator, extensive electrical upgrades (including 400-amp service and new circuits), fire sprinkler system improvements on the third floor, and the addition of a rear deck and exit stair. The building's safety features were further enhanced with the installation of a comprehensive automatic fire sprinkler system in 1992 containing 107 heads.

Recent activity at the property has primarily involved routine maintenance and parking-related issues, with multiple reports of driveway blocking between 2018 and 2024, and various street cleaning matters. A potentially concerning incident was recorded in the fire incident file as a "toxic condition, other" with no civilian injuries reported, though no specific date or details were provided. The building's infrastructure upgrades from 2003-2004 included significant improvements to both residential and commercial spaces, with particular attention to fire safety, electrical systems, and accessibility, though the 2020 accessibility modification indicates ongoing challenges in this area.
