(1) If under the lease agreement the lessee is intended to sublet the leased residential space to a third party on a commercial basis for residential purposes, then upon termination of the lease the lessor accedes to the rights and duties under the lease agreement between the lessee and the third party. If the lessor enters into a new lease agreement for subletting on a commercial basis, then the lessee, in place of the previous contractual party, accedes to the rights and duties under the lease agreement with the third party.
(2) Sections 566 to 566e apply accordingly.
(3) A deviating agreement to the disadvantage of the lessee is ineffective.
