269-271 21st Ave, San Francisco, CA 94121

The two-unit residential building at 269-271 21st Avenue in the Central Richmond neighborhood, owned by Amesbury Trust, was constructed in 1917 as a two-story flats and duplex structure. The building's maintenance record shows two significant permitted improvements: a completed reroofing project in December 1992 and a completed horizontal extension with new skylights installation in August 1987.

These improvements indicate attention to building maintenance and structural enhancement over the years. The property has experienced multiple parking-related issues in recent years, with six reported incidents between 2019 and 2025, including three documented cases of driveway blocking (in April 2021, February 2020, and July 2019) that required parking enforcement intervention. There were also three reports of abandoned vehicles on nearby streets between May and October 2019, though all vehicles were either gone upon arrival of authorities or complied with regulations when contacted.

Of notable concern is an open case from April 2021 regarding tree roots lifting the sidewalk, which could potentially affect pedestrian safety and property access. The building's vicinity has experienced occasional litter and debris issues, with three reported cases in 2025 (Christmas tree), 2022 (loose garbage), and one parking-related incident in November 2021. In terms of infrastructure maintenance, the most recent building permit on record is from 1992, suggesting that no major structural improvements have been undertaken in over three decades.
