quiet enjoyment is this really a thing?

[Dustin J Woods]

I modified a house with a walk out basement from Single Family into 2 units. My plan is to live in the smaller downstairs unit. I finished the upstairs renovations and now have renters in it, but the down stairs is not finished. It needs a lot of work. I've been trying to be accommodating about the process but the tent is not being cooperative so now my contractor pulled the plug because he is afraid of this Quit Enjoyment law. When I say the tenant isn't cooperative, I mean that I asked if we could work until 9 pm and her response was I want in writing what hours you plan to be working. That didn't answer my question. This is just one example of how my conversations go with them. Ugh! So frustrating. Before they even signed a lease we had several discussions about me living there. Should I just leave it until the lease is up? If I push the issue could they really sue me or something? What's the worst case scenario?
