619 Clayton St, San Francisco, CA 94117

The 2-story, 4-unit multi-family residential building at 619 Clayton Street in Haight Ashbury, owned by the Sanguinetti Family Trust Ag and constructed in 1904, has undergone significant recent improvements, most notably the addition of a ground floor accessory dwelling unit in 2016 (completed at a cost of $78,842) which included comprehensive fire sprinkler installation and modernization work totaling over $40,000. The building has seen substantial unit improvements between 2016 and 2019, including bathroom and kitchen remodels in various units, electrical upgrades, and the installation of a 200-amp service with six-meter main for five units. A notable plumbing emergency occurred in February 2022 involving a collapsed sewer that was promptly repaired.

The building had historical violations in 2002-2004 related to an unauthorized basement unit and various maintenance issues, including fire safety concerns, which were all resolved and are now marked as not active. Recent maintenance and safety improvements include the installation of a sprinkler monitoring system in 2019, though there was an expired permit for an attempted domestic water service replacement from 2019. The property has experienced recurring issues with illegal parking and graffiti in the vicinity, as evidenced by multiple 311 calls in 2023-2024.

Two fire incidents were recorded, but neither resulted in injuries or actual fires. The building appears to be actively maintained, with no current open violations or active tenant complaints, and recent work has focused on modernizing building systems and maintaining safety compliance. The most recent tenant buyout occurred in September 2018, totaling $46,300 for one tenant.
