Ooh, I actually know a little bit about this!
A property owner can put whatever TF restrictions they want in the lease—and they often do! But just because it's in a contract doesn't mean it's legal (e.g. contract to kill).
Let's say a property owner finds out their tenant is working from home. They claim a violation of the lease and start eviction proceedings. That's dumb AF.
- This would only ever be used as an excuse for a tenant they don't like.
- If it came before a judge, even they would be like, "WTF?" And would probably not demand an explanation, but instead would point to mountains of case law that say a property owner can't dictate what people can and can't do within a rental property as long as those activities don't impact the property (e.g. the value).
- That's when the property owner would have to explain how Joe Schmoe working from home is somehow worse than retiree Judy Anywoman who stays at home all day every day.
