My land lord entered my home today for "insurance purposes" without my permission while I was not home he told me he would be there at 11 as I work until 10 but when I arrived home I found he had entered at 10 while I was not home Is that legal? Also he says I have to clean my home within 72 hours as if he would evict me if I did not. My home is not unreasonably messy just your usual hectic lifestyle misplacment of items can he do that?

In most states, the landlord may not simply enter your domicile without prior notice. The only exception to this is in the case of emergencies (ie. Gas leak, fire, water leak, etc.). Otherwise, the landlord must give you 24 hours of notice before he enters. As a tenant, you have the right to "quiet, enjoyment" of your apartment.

Agree, normally he has to give 24 hour notice, but he does not have to have your permission. He just needs to tell you he will enter. You do not have to be home.

I have seen many peoples idea of "lived in" so that is a issue the courts may decide with photos taken if need be.

... Also he says I have to clean my home within 72 hours as if he would evict me ...

Do you have a lease? If so, tell him (your choice):

"no";
"Hell, no".
"Stick it";
In the immortal words of the American general at Bastogne, "Nuts.";
"See me in court";
or another similar response.

Unless the condition of the premises is a health or safety matter, he has no right to control how tidy your home is.

Apparently he did give you notice, arrived early and decided not to wait. So it sounds like nothing is wrong there.

Unless you have a lease that specifies a level of cleanliness that must be maintained, the landlord has no say on your housekeeping skills.Unless there is a fire or health hazard, he can't evict over cleanliness. However, if you don't have a lease he can usually terminate your tenancy on 30 days notice for no reason.
