1264-1266 21st Ave, San Francisco, CA 94122

The three-unit multi-family residential building at 1264-1266 21st Avenue in the Central Sunset neighborhood, currently owned by Hum Trust, is a two-story structure built in 1988. The property's development history shows a complete transformation from a single-family dwelling, which was demolished in September 1987, to its current configuration as a three-unit residential building, with a basement guest room and bath added in 1989.

Two building permits from 1988 are of note: one for relocating a fireplace, entrance door, and trash cans, and the other relating to street space usage in September 2018 at minimal cost. In recent years, the property has experienced recurring issues with driveway blockages, particularly between 2023 and 2024, with five documented incidents requiring parking enforcement intervention, though often resulting in officers being unable to locate the offending vehicles.

While these parking issues may suggest a pattern of inconvenience for residents, they are external to the building itself. An unrelated incident involving illegal postings was reported in October 2017. The property's documented history shows consistent residential use since its 1987 conversion, with no recorded building code violations or major structural issues in recent years, though the concentration of parking enforcement calls in the last two years is notable.
