is landlord random apartment inspection legal?

[Arty Fresh]

I attached the letter that all the apartments received today. It says that they need to come inside all our apartments this week only to look around. I want to know what are they going to look for? they never done this before in the past 15 years I lived here.

should I hide any cash, credit cards or jewelry that is laying around the house and electronics as well that can possibly become stolen?

I am sure they are going to check everyones apartment to see if anyone is growing drugs, weapons, and what ever other illegal activities there could be going. I think this is a cover up scheme and possibly home invasion to ezzz drop on people.

what do you guys think
