1546-1548 20th Ave, San Francisco, CA 94122

The two-unit multi-family residential building at 1546-1548 20th Avenue in the Central Sunset neighborhood has a documented history dating back to its 1945 construction. The duplex, currently owned by "Dear Jerry", has undergone several significant infrastructure improvements over the years, including a major electrical upgrade in 2010 that enhanced the service capacity to 200 amps with dual meters and sub-panels, and earlier improvements such as aluminum window installation in 1986 and rear stair repairs in 1993.

The most pressing recent concern involves a notable pattern of waste accumulation and debris management challenges in the vicinity of the property throughout 2024, with multiple reports (at least ten documented cases from February through December 2024) regarding garbage and debris on the street and sidewalks. These incidents, primarily involving loose garbage, yard waste, and abandoned furniture or appliances, have generally been resolved by city services, though several cases were marked as "Closed Unable to Locate".

While these external conditions do not necessarily reflect on the building's internal maintenance, they represent the most significant recurring issue in the building's recent history, particularly during the most recent year of available data. The property's maintenance record shows regular attention to structural and safety improvements, with no documented safety violations or recent building code infractions.
