If we allow this logic what is to stop the following situation:

    1. Landlord writes into rental agreements that they could have someone inspect the property every year.

    2. Sold access to people's apartments to police officers every year.

In this situation a third party secured access to something which is traditionally constitutionally protected. This third party is in a position of power that is hard to bargain with (as many tech companies are). Most people wouldn't agree to this if they had the option to say no and would not expect this lease clause to be used this way.
