Landlord Got Arrested, Now The Police Want To Search All Tenant's Rooms. How Should I Handle This?

Location: Suffolk County, New York. So my dad, who is technically my landlord, got arrested because he got into a fight at a store. A man got in his face, wouldn't back up and even pushed him a few times. My dad ended up hitting the guy one time and then the guy called the cops. My dad (landlord) is now on 1 year probation, and his PO says they will be searching the whole house. My dad told him that he rents out rooms and the PO says that it doesn't matter and everyone is subject to search at anytime since he is the owner of the property.

We have 3 rented rooms, me (eldest son), my sister, her husband and child in another room, and the 3rd room is just a straight up regular tenant. My dad technically doesn't have a room because he doesnt even live on the property and just rents it out, but he never changed his legal address. My dad explained this to the PO and he says that it doesnt matter and all my dads properties are subject to complete searches at anytime, doesnt matter if the space is rented by someone else. My dad's lawyer is also saying this is true and we must allow them. No one wants to be searched, and from my research, as a tenant that pays rent I have a certain level of rights and privacy. Ive read that a PO can search the common areas and the personal rooms of the probationee. But the rented rooms are off limits without a warrant.

It's not that I have anything to hide, for me its more of the principle of the matter. I feel like my 4th amendment right is being violated. I didn't commit a crime.. so why would my personal paid for space be subject to search. I dont plan on physically obstructing the officer if it comes to it, but I will object, deny consent, film and document the interaction, and get myself a lawyer.

Thanks for any advice, it is greatly appreciated!
