563 40th Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 563 40th Avenue in San Francisco's Outer Richmond district, owned by Diamond-1 Trust, was constructed in 1907 and is classified as a two-story apartment dwelling. The building has undergone several significant modifications over its history, most notably a horizontal addition completed in 1993, and more recently, in 2019, the replacement of a garage door at a cost of $1,000.

Historical permit records from the late 1980s and early 1990s show various proposed improvements including electrical work, sheetrock replacement, and attempts at adding basement facilities, though some of these permits were either cancelled or expired. In 2023, multiple reports were filed regarding sidewalk and curb defects in the vicinity of the property, with at least one curb defect complaint still showing as open in March 2023.

The building's maintenance record includes a fire complaint from June 2013 regarding combustible materials, though the condition was reportedly corrected the same day. While there have been numerous incidents of reported abandoned vehicles and parking violations in the immediate area throughout 2024, these are external issues not directly related to the building's conditions. A tenant buyout was recorded at a nearby address (543 40th Avenue) in 2017 involving three tenants and totaling $26,000, though it is not directly linked to this building's current status.
