2455-2457 Post St, San Francisco, CA 94115

The three-unit residential building at 2455-2457 Post Street in Lower Pacific Heights is a three-story flats and duplex structure built in 1900, currently owned by Kevin Kelly and Marg Cullinan. The building has experienced significant plumbing and sewer issues in recent months, with three separate sewage backup incidents reported between December 8-12, 2023, involving 4-inch vents and manhole covers, as well as a sewage discharge incident in July 2024.

In July 2008, the property underwent repairs from minor fire damage affecting two bedrooms, which included sheetrock replacement, floor refinishing, and surface repainting, along with the installation of a new gas furnace and associated ductwork, and the addition of smoke detectors and electrical outlets. The building has a history of maintenance work, including two separate roofing projects (in 1995 and 2001), a horizontal addition and skylight replacement in 1989, and a compliance upgrade in 1985. More recent calls for service have primarily been related to exterior maintenance issues, including garbage and debris removal, tree maintenance, and parking violations.

The property has experienced several fire-related incidents through its history, though none resulted in injuries or significant damage, including cases of system malfunctions, gas leak detections, and a contained cooking fire. The building underwent a routine housing inspection in November 2000, which was promptly addressed, and all reported issues have been resolved according to official records. The most recent structural modifications were focused on basic upkeep and compliance with safety standards, and no major renovations or changes to the building's footprint have been recorded in recent years.
