OT, and not even politics.
I know only a few of you are experts on Maryland law, but I think it's typical of US law on this.
If an area is zoned for business, is one allowed to build a home, or an apartment whose building is no larger than a business would be allowed to be?
I seem to remember that less problematic uses were permitted. The goal was to keep business and factories out of residential areas, but not the other way around.
(And also be4ween levels 2 and 3. For example, a business could be built in an area zoned industrial, even though the reverse would not be true without special permission. But I don't care much about this one because the dispute on Nextdoor is between business and residential.)
When I google I get lots of hits about what is famously not permitted, and not about this, whether permitted or not. And that's why I ask here were intelligence is available and not merely artificial intelligence.
