Ok, there's no need to get so defensive. None of that came through in your post.

My dad was a landlord for years and while I get what your saying about your landlord not having experience with what's going on there, it is HIS property and he is responsible for it, so he should be learning about it and doing something, not passing the buck to you.

Yes, there are privacy laws that can cause issues here, but he can easily get around them. When we found out someone was using our property to grow pot once (from the neighbor, much like you, and thank goodness for people like you) he scheduled a check to go look at the water heater and change the filter on the air conditioner and was able to find the remnants they weren't able to move fast enough and evict them.

Your landlord could easily find a way to access the house and if he smells the pot, verbally warn them and then send them a letter letting them know pot is illegal (which they should clearly know) and that if he finds out it happens again he will have to evict them. That's if he wants to give them a warning. If not, he could evict them right then.

I'm not saying he's a bad landlord or a bad person, but he is passing the buck to you when there are certainly things he could do to try and help solve this problem. And if he wants to protect his property, he should try to keep people renting it who aren't criminals. I mean, you might have to move at some point if you can't get this woman out and her crazy criminal ex keeps coming back and messing with her (and because you are close by, you) and you seem like a great tenant so he would lose the good tenant and keep the crap one all because he couldn't be bothered to figure out how to solve this problem and instead pushed it off onto you.

It's really not absurd at all. It's just good business.
