1280 21st Ave, San Francisco, CA 94122

The 2-unit residential building at 1280 21st Avenue in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1989. The property has undergone two significant permitted modifications: a substantial structural change during construction in 1989 (changing from trus joist to 2x12 as per engineers' plans), and a notable interior expansion in 2001 when an additional two bedrooms and full bathroom were added to the ground floor at a cost of $12,000.

A fire safety inspection in September 2015 identified combustible materials on the property, though this issue was promptly corrected within four days. The most pressing current concern involves an ongoing situation with waste management on and around the property, with multiple "garbage and debris" incidents reported between December 2024 and January 2025.

Specifically, there are three unresolved cases as of now involving loose garbage, yard waste, and potentially other debris, with additional reports of abandoned furniture and defaced parking signage. While most previous waste management issues in this series have been resolved, the persistence of recent complaints suggests an ongoing challenge with waste disposal in the vicinity. The building's documented history shows that while structural modifications and fire safety issues have been properly addressed in the past, the current environmental maintenance challenges appear to be a more immediate concern, though they relate primarily to the street and sidewalk areas outside the building rather than the structure itself.
