If you are on a true sub-lease with the actual tenants of the owner/landlord of the premises that you occupy where you have the entire unit as a sub-lease, under the laws of all states in this country, you are entitled to the premises and not the actual tenants now. You can simply ask your "landlord" to leave the premises with allowance for the typical 24 hour notuce to show the unit and to inspect it. If such does not get the result you want then there is material breach of the sub-lease.
