That's illegal. Period. And no, you shouldn't have to change your shower curtain. It's called privacy! If you're paying rent then you have a right to lock the door(s) in order to feel safe in your home. Tell this control freak that if she wants her rent money you must establish a few boundaries beginning with her brats.

invasion of privacy much?

Not allowed to lock the door? Have you a contract? It's not legal that situation

Start calling the police to report "unknown intruders" in the house when your landlord walks in unannounced for no reason. Be sure to tell the 911 operator how scared you are, and how you are hiding in your bedroom. Cops will show up guns drawn. As for brats walking in on your showers - pepper spray will solve that. Tell the cops you were in the shower, and the unknown intruders (you could not see - you were in the shower) scared you. Fearing for your safety, you pulled back the curtains and sprayed whoever was there. Practice your story a few times so you can tell it without laughing. The landlord will get the idea. Then look for a new place to live, once your lease is up rent will increase.

No matter WHAT's in the contract, the LAW's still the law, and you CANNOT put something ILLEGAL in a "contract" to "make" it "legal": it STILL and nevertheless IS illegal! It's her property, right, but she LEASED it to you: the right to USE this property - and YOU have the right to PRIVACY in your leased house/flat!

Get a different shower curtain

Wear a bathing suit in the shower! That'll show em.

All of you making comments about getting a new shower curtain are IDIOTS!!! The frigging shower curtain is NOT the problem here. The kids seeing her naked, and walking into her home is, it can get her into trouble as well as the landlord. This unstable woman has opened a whole can of trouble with these kids putting this person in this situation. Where talking molestation charges, for or against her! HOW CAN YOU IDIOTS NOT SEE THIS???

I thank I would be moveing out ASAP

That's illegal!
