100 Scott St, San Francisco, CA 94117

The two-story, five-unit multi-family residential building at 100 Scott Street in Hayes Valley, owned by Kingsley Properties LLC, has undergone several significant safety and infrastructure upgrades since its construction in 1959. Most notably, in 2023, the building received a comprehensive fire safety upgrade including a new addressable fire alarm system, smoke detectors, pull stations, and low-frequency horns in all residential sleeping areas, with associated electrical work completed in July 2023.

The building has successfully completed its mandatory seismic retrofit program (Tier 3) and roof replacement, demonstrating compliance with key safety requirements. Prior improvements include the replacement of 29 windows in 2019, including bedroom egress windows and those providing access to fire escapes, as well as the addition of a new ADU at the ground floor (though this permit was ultimately cancelled). The building's history reveals a pattern of fire safety concerns in the late 2000s, with multiple violations recorded in 2008-2010 related to fire extinguishers, escape routes, and fire-proofing, all of which were abated by December 2008.

More recent fire alarm system issues were noted in 2015, though these were promptly corrected. Building complaints from 2010-2012 indicated some maintenance challenges, including dry rot, window leaks, and hot water supply issues, but these were all resolved. The property has experienced recurring exterior maintenance challenges, as evidenced by multiple recent 311 calls regarding graffiti and sidewalk cleanliness between December 2024 and January 2025, though these are primarily street-level issues rather than building-specific problems.
