601 Burnett Ave, San Francisco, CA 94131

The 7-unit, 3-story multi-family residential building at 601 Burnett Ave in Twin Peaks, owned by Trilateral Inc, has undergone significant improvements to its life safety systems in recent years, most notably with a comprehensive fire alarm system upgrade completed in March 2023 costing nearly $35,000, which included the installation of new smoke detectors, heat detectors, pull stations, and horn/strobes. The building has a history of structural maintenance and improvements, including several deck replacements, window upgrades, and roofing work between 1992 and 2022, with the most recent deck-related improvements occurring in 2017.

The property has maintained an active maintenance schedule, addressing various building and safety requirements over the years, though it has experienced some notable issues. In 2017, there was a complaint regarding unsealed work areas and potential lead paint disturbance, and multiple violations were recorded between 2001 and 2017 related to ventilation, fire safety, and weatherproofing, all of which were subsequently abated.

While the building has experienced numerous false fire alarm activations and one smoke detector activation incident (all with zero civilian injuries), these incidents generally correspond to system malfunctions rather than actual emergencies. Recent activity at the property has primarily involved routine external maintenance matters, as evidenced by multiple 311 calls for sidewalk cleaning and general maintenance in late 2023, though these are typical for the area and not indicative of any systemic issues with the building itself.
