Dealing with a landlord is just like dealing with HR at work - they aren’t there for YOU. The tenant here wasn’t stupid, just naive. Besides, from a liability standpoint, a tenant should NEVER do any property upgrades or repairs without some kind of written agreement (and hopefuly waiver of liability). If something goes wrong, guess who will be on the hook financially when it goes to court? Hint: The landlord turned plaintiff won’t be it…
