2645 Polk St, San Francisco, CA 94109

2645 Polk Street is a 12-unit, 3-story multi-family residential building constructed in 1950, currently owned by Mehan Properties LLC. The building has undergone several significant infrastructure upgrades in recent years, including a steam boiler replacement in June 2023 and an upcoming fire alarm system modification scheduled for August 2024 that will include upgrading the fire panel, updating devices for compatibility, and installing low-frequency sounders in sleeping areas.

Historical maintenance records show a complete reroofing project costing $19,250 in 2002, though there have been some recurring issues with building systems that required attention, such as a 2015 backflow device replacement and a 2014 water heater installation. The building has experienced periodic fire safety concerns, with violations documented in 2021 related to fire extinguisher hydro-testing, building owner contact posting requirements, and alarm system maintenance - though all these violations were subsequently abated.

There was also a fire complaint in 2021 regarding the alarm system that resulted in a violation being issued, and a carbon monoxide detector activation (with no CO detected) recorded as a fire incident. The property has undergone routine housing inspections between 1999 and 2011, with a notable series of violations in 2006 concerning malfunctioning emergency exit lights and damaged ceiling repairs in exit hallways, which were all abated by May 2006. Recent activity around the property includes several 311 calls regarding street cleaning issues between 2021 and 2024, and a graffiti incident reported in September 2023, though these exterior maintenance matters don't directly impact building safety or resident experience.
