3645-3647 Irving St, San Francisco, CA 94122

The multi-family residential building at 3645-3647 Irving Street in San Francisco's Outer Sunset neighborhood is a two-unit structure built in 1946, classified as a Flats & Duplex building, and currently owned by the William & Debra Demattei Trust. The building's maintenance history includes several significant works: in 2004, the rear stairways were repaired in-kind and a reroofing project was completed, though these stairway repairs initially triggered a building violation due to work being performed without proper permits, which was subsequently resolved by June 2004.

Earlier maintenance records show side steps repairs were completed in 1992, and more recently, water service improvements were undertaken in October 2011, with one permit expiring and another being properly completed. The property has experienced various street-level issues in the surrounding area, particularly in recent years, including multiple reports of garbage-related concerns in 2024, such as debris and garbage management issues.

There were also several instances of vehicles blocking driveways in 2021, with citations issued in at least two cases. A construction noise complaint was addressed in August 2024 related to nearby work, and there have been regular calls regarding street cleaning and maintenance from 2018 to 2024, suggesting ongoing challenges with waste management in the vicinity. While these external issues do not directly impact the building's structure or systems, they provide context about the building's immediate environment over the past several years.
