100-102 Corbett Ave, San Francisco, CA 94114

The two-unit residential building at 100-102 Corbett Avenue in Corona Heights is a two-story flats and duplex structure built in 1953, currently owned by Joseph E. Kelley and Gary Lea. The building has undergone several significant improvements over the years, including a comprehensive window and door replacement project in 2011, which involved installing 18 windows and 2 doors with fiberglass frames and energy-efficient specifications at a cost of $21,000.

Earlier renovations include a reroofing project completed in 1991 and the installation of underground electrical service in 2004. A street space and sidewalk permit was issued in 2009. The property and surrounding area have experienced notable environmental maintenance challenges in recent months, particularly during 2024, with multiple reports of garbage and debris issues, including three instances of overflowing city garbage cans and other waste concerns between March and November 2024.

The area has also faced some infrastructure and maintenance issues, such as a defaced parking sign in March 2024, problems with overgrown and damaged trees in early 2024 (including emergency removal of a fallen tree in February), and a graffiti incident in December 2023. While these external issues have been systematically addressed by city services and marked as resolved, they may impact the immediate residential environment. The building's permitted improvements suggest regular maintenance and upgrading of core systems, though no recent structural modifications or major system overhauls have been recorded.
