I agree with Rich, if you own your home but pay for the land, they have no right to tell you what you can have, unless it is roaming around outside like a dog.

I also agree in that it is law to give notice before entering into someones home. Every apartment I have lived in, they have to give a notice, or if it is an emergency, they try to call me first.

If you signed leases saying they can come in whenever they want, you need to find new landlords!
