It seems odd that entering the apartment was considered illegal. Normally, entry into an apartment requires either the permission of the apartment tenant or a representative of the owner. If the property manager gave permission for entry, there's no fourth amendment violation.

There is if the property is leased out. The lease must specifically spell out the conditions that the landlord can enter the apartment.
