1826-1828 Greenwich St, San Francisco, CA 94123

The two-unit residential building at 1826-1828 Greenwich Street, owned by Valerio & Marisa Michelini, is a two-story flats and duplex structure built in 1930 in the Cow Hollow neighborhood. The building has undergone several significant infrastructure improvements over the years, including window replacements in 2003, reroofing work in 1995 (though this permit has since expired), and a complete water service replacement in 2012.

Of particular concern is a pattern of plumbing-related issues, including a sewage backup incident in November 2019 that was notably the third such occurrence in a month, and a flooding incident in September 2012 that was determined to be water-related rather than sewer-related. The property has experienced various maintenance and environmental challenges in recent years, with a concerning escalation of noise-related complaints in late 2024, as indicated by two open excessive noise reports from November 2024.

The building's vicinity has also faced recurring issues with street cleanliness, including multiple reports of human or animal waste between 2018 and 2019, and reports of medical waste (needles) in June 2019. There have been recurring parking enforcement matters, with at least two documented cases of driveway blocking in 2020 and September 2023, both of which were resolved through citations. The building's maintenance history shows attention to basic infrastructure updates, but the clustering of plumbing issues and recent noise complaints warrants attention to the building's environmental context and systems performance.
