My Landlord Gave Notice Of Entry For The Duration Of Three Months With No Actual Dates

Location: Indiana
I got an email from my landlord today saying that they and vendors will be entering units from May 11th - August 18th to prepare for new tenants; they also said we are not to keep items in common areas that are not “decorative” and we must keep our bedrooms closed. Is this allowed? They also said we have to remain in our bedrooms while they are in our unit to “minimize interference” with the vendors. This is ridiculous, right? They’re giving us a 3.5 month time frame where our house could be entered at any time, and we would then be forced to stay in our bedrooms for an indefinite period of time.

We chose to live in a townhouse for the added benefits of having a proper living room and kitchen, we cook and watch tv in our living room almost daily, but now they can just come into our house during the day and kick us out of our living room/kitchen/craft room? I also have a cat who we let roam the house during the day, so I guess she has to spend the next three months locked in my room when I’m not home??? Also, our kitchen supplies aren’t decorative, so do we have to put those away too?? We have countertop appliances that wouldn’t really fit anywhere else and other kitchen stuff (ex cooking utensils, dish drying mat, etc) that live on the counter. We also have one of those plastic dresser type things full of games that stays downstairs, along with a beanbag and a keyboard + chair.

ETA:
Clarifying details:
each of the three bedrooms has a separate lease (housing complex is targeted at college students)

common areas include the kitchen, living room, half bath, and downstairs living space (including washer and dryer) which we turned into a craft room

my current roommate and I both have leases through July of 2027

our third roommate moved out, so they’re trying to get that space ready for the new tenant who’s lease starts in August

The new roommate is my long term partner who’s been to the house nearly everyday, so she won’t be shocked by anything in the common areas

I also spoke to the leasing office and found out the third roommate never gave her keys back so they can’t start fixing anything until that happens (or her lease expires in two months
