2331 Folsom St, San Francisco, CA 94110

The three-story multi-family residential building at 2331 Folsom Street, owned by Paulina V. Espinoza, was constructed in 1904 and contains three units. The property has undergone several significant events, most notably its participation in San Francisco's mandatory Soft Story Retrofit Program, which was documented as a violation in November 2017 when the owner failed to submit the required permit application and plans for seismic retrofit work.

This violation, along with associated monthly violation monitoring fees and requirements not to remove an earthquake warning placard, was ultimately abated by March 2018. The building's infrastructure maintenance includes completed reroofing work from 1989 and electrical upgrades for underground utility conversion in 2004. Recent records show a pattern of false alarm activations from 2017 through 2021, primarily related to the building's alarm system and smoke detectors, though none resulted in actual fires or civilian injuries.

The property has experienced an active 311 service record in recent months (2024-2025), with numerous calls related to street cleaning, parking enforcement, and streetlight issues, particularly focusing on problems with vehicles blocking driveways. While these external issues aren't directly related to the building's condition, they reflect the surrounding neighborhood environment. The building's fire safety systems have had multiple activation events, including a cooking fire that was confined to its container, but no serious incidents or injuries have been recorded.
