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.
