Check the lease for any of these stipulations. If they're not in their report her to the police as it's not only a matter of your safety but also privacy. If those ridiculous stipulations are there break the lease and move out, but still report her.

i thought landlords had to give 24 hours notice when they want to come over? or is that just in england?

On the other hand, next time you shower, be prepared to flash them something that will frighten and disgust them. I'm thinking broccoli, homework or exercise.

That is totally illegal dear. Talk to legal aide about this because if you signed a lease, it is considered imminent domaine and your property until the leaser reclaims the property.

Um no. Your landlord has to give you notice prior to coming to pay a visit. Look up your states law regarding rentals and then show t to her and lock your fracking door!

OP is saying her money, so its not cheerity.. that landlord need to stfu and mind her own business -.-

That's illegal for her to not allow you to lock your doors. And those 2 children are not only intruding into your home but invading your privacy. I would be addressing that with her if I were you. Just because she owns the building, doesn't make your rented space that you pay good money for hers to invade. Next time they come in your space uninvited call the police and even social services for her poor supervision of her children.

That's illegal

File for sexual harassment maybe? If possible

It is not ok for her to come up. When she became a landlord she gave up her right to that part of the house. It's actually illegal so you can file a complaint against her with housing authority
