9-11 Carl St, San Francisco, CA 94117

The two-unit residential building at 9-11 Carl Street, owned by the Thorina H Rose Living Trust, is a two-story flats and duplex structure built in 1908 in the Parnassus/Ashbury Heights neighborhood. The property has undergone several significant maintenance and safety improvements in recent years, most notably a comprehensive rear renovation in 2021 that included the replacement of rear siding (450 square feet), installation of 12 new rear windows, repair of dry rot in framing, and replacement of a non-conforming rear stair, totaling approximately $43,000 in improvements.

A previous attempt to address stair safety issues in 2020 and 2012 was withdrawn, highlighting the importance of these completed renovations. The building's systems were updated in 2013 with the installation of a new York furnace. The property has experienced several parking-related issues in recent years, with multiple complaints about driveway blocking between 2023 and 2024, though responders were often unable to locate the offending vehicles.

There have been minor neighborhood maintenance issues recorded, including a defaced parking sign in 2019, two resolved cases of graffiti and illegal postings in 2013, and a sidewalk defect due to tree roots documented in 2010. Historical records show various interior improvements from 1997-2002, including bathroom fixture replacements, pantry modifications, and kitchen renovations, indicating regular maintenance of the unit interiors over the years. The building's recent permit history demonstrates significant attention to safety compliance and structural maintenance, particularly regarding egress requirements.
