140 Seal Rock Dr, San Francisco, CA 94121

The two-unit residential building at 140 Seal Rock Drive in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1947, currently owned by Terence W. and Nancy F. Chan.

The building's maintenance record shows minimal permitted work, with only one documented roofing project from 1995, though this permit has since expired. The property has experienced some external infrastructure issues relating to public spaces in close proximity to the building. In October 2020, there was a resolution regarding a lifted sidewalk and a missing round sewer cap that required transfer to monument services for correction.

More recently, in January 2021, there was a report of trash dumping in the neighborhood that was handled by the Parks Department and transferred to the Golden Gate National Recreational Area authorities. While these incidents occurred near the property, they were primarily related to public infrastructure and neighborhood issues rather than problems with the building itself. The historical data indicates limited recorded maintenance or improvements to the structure over the past three decades.
