Can my landlord post this notice?

We will be entering your apartment during the next two weeks. If you have a pet, please make sure pet is secure or off the premises. Please remove all items from outside storage closet or you will be charged a fee of $150 moving per item.

This is your 48 hours notice we will be in your apartment sometime over the next two weeks.

Can they do this? I mean, doesn't the 48 hour notice get voided after 48 hours?
Update: Sometime in the next 2 weeks they are installing washer and dryers into our units. They want us to clear out our outside storage garage for the next 2 weeks to do the set up. They have not given us any specific dates and I don't want to lock my dog in a warm bedroom if I don't have to..
Update 2: I don't want to lock our dog in a bedroom for 2 weeks, and I also don't want all of our christmas decorations, books and stuff all over the apartment for 2 weeks. Our apartment is small, and a little clutter makes it look very messy. Also, there is really no-where to put any of that stuff that is convenient and... show more I don't want to lock our dog in a bedroom for 2 weeks, and I also don't want all of our christmas decorations, books and stuff all over the apartment for 2 weeks.

Update 3: We are under lease for 10 more months. I would *LOVE* to break our lease, but I can't afford to do so. We are saving for a house right now.
