I'm sure there's lots, but lease says no X, tenant insits on doing X seems like a reasonable thing to evict about, but not a reasonable thing to ask the police to adjudicate.
At least as long as 'no X' is a reasonably moral thing to restrict. So no pets, no working on cars in the parking lot, no smoking, no loud noises/no more than N police noise complaints, etc. At least my moral code allows one to form a contract that restricts such thing and that when one party refuses to honor a (reasonable) contract, the other party should be able to require the breach be mended or the contract be ended, and that some breaches can't be mended.
Some things that might not be stated in a lease but would also be reasonable to evict for could include no interfering in the quiet enjoyment rights of neighbors, no storing of dangerous goods, no causing dangerous/unsafe situations.
Why is it moral to restrict random stuff in a rental contract? Would no programming be moral to you?
I don't see why that would be an immoral restriction.
I don't think it's a reasonable restriction, but unreasonableness doesn't make it immoral. At the same time, if you make an agreement not to program in a rental and then you program, shouldn't you need to stop or leave? I might have moral concerns about how one enforces a restriction against programming, it's probably intrusive
Now, if your question is no programmers and/or no overnight guests who are programmers and/or you can have six tenants in the unit, but no more than three who are unmaried programmers... Then my moral compass is pointing towards no. Restricting the practicing of a profession on premesis seems fine, descriminating against the practitioners is ick.
Pets, and car maintenance can both damage the property. Noise in the quiet time disrupts other tenants
Does programming cause property damage or impact other tenants?
