637-641 Cole St, San Francisco, CA 94117

The three-unit residential building at 637-641 Cole Street in Haight Ashbury is a three-story flats and duplex structure built in 1906, currently owned by Richard and Kathleen Hardwig. The property has undergone several notable maintenance activities over the past two decades, including two roofing projects — most recently in October 2019 at a cost of $15,450, and an earlier project in 2000 which expired at $8,995.

Street space and sidewalk repairs were completed in 2008, demonstrating attention to exterior public areas. The building has experienced periodic maintenance issues and housing inspections, with a significant fire safety violation in 2006 regarding fire proofing materials, though this was abated within two months.

Other tenant-reported issues included a malfunctioning kitchen appliance and plumbing problems in 2011, rat infestations and a broken front door frame in 2007, and various routine inspections throughout the 2000s that were promptly resolved. While there have been four graffiti incidents reported near the building between 2016 and 2022, these were typically addressed promptly by city services, and there has been one case of loose garbage requiring general cleaning in 2018. The property's documented history suggests regular maintenance and prompt response to violations, though the presence of multiple graffiti incidents and some maintenance issues over the years may be worth noting.
