Yes, I was the one who provided the original image that is attached to this note. IANAL, but I am pretty sure we are not violating Google's copyright by merely discussing their streetview image. All we are using it for is to determine that the building still looked the same in 2024 as it did when I photographed it in 2021.

All that being said, I think the main issue is what it means for the building to be "abandoned". It may be legally owned by the city because no one is paying tax on it or claims to own it. Or it may be in that condition because the owner for some reason doesn't want to use it. If there a glossary somewhere for OSM?
