267 24th Ave, San Francisco, CA 94121

The three-story duplex at 267 24th Avenue, owned by the Thomas I & Kay K Koike Trust, has undergone several significant infrastructure improvements since its construction in 1922. The building's mechanical systems have been notably upgraded, with the installation of new hot water boilers in both 2011 and 2007, including a 75,000 BTU unit and a Laars boiler with circulation pump and expansion tank.

The electrical system received a significant update in March 2013, when 125-amp three-gang metering and multiple panels were installed for both units, along with additional outlets in unit 269. A street space permit was issued in July 2020, though the cost was listed as $0.00. The property has experienced typical urban challenges, with the most recent issues documented through 311 calls.

These include an open pavement defect report from August 2024, and a street cleaning issue related to loose garbage in August 2023, which was resolved with before-and-after photos. A notable incident occurred in March 2013 involving a sewage backup, which was promptly addressed and resolved by the PUC Sewer Operations through flushing and maintenance of both the side and main sewer systems. Between October 2016 and July 2017, there were multiple reports of abandoned vehicles in the vicinity, all of which were resolved when the vehicles were found to be gone upon inspection.
