buildings have copyright laws?
Yes, some building registered trademarks and the style or design may be protected from copying, FOR COMMERIAL purposes.
You may photograph any building, place or thing from any publicly available space, such has roads and sidewalks. basically if you can see it, you can take a picture of it.
If you intend to or eventually make a profit from the image of the building you MAY be sued.
A great example of this is the Rock and Roll and Hall of Fame. Years ago a photographer took a picture from the street and make t-shirts from the image. He sold these and was promptly sued by the buildings architects, designers and management.
Eventually he won, he took it from a public place and millions of the same images are available on FB and the web. it took years and cost a fortune, but he did win.
