From the point of view of the respective obligations of the parties, restrictions on the enjoyment of the premises and obligations normally incumbent on the lessor, which the lessor would have discharged on the lessee without consideration, constitute a factor reducing the rental value. The same applies to obligations imposed on the tenant over and above those arising by law or custom. Improvements made to the rented premises during the course of the lease to be renewed are only taken into account if, directly or indirectly, in particular through the acceptance of a reduced rent, the lessor has assumed the cost of such improvements.
Obligations arising by law and generating charges for either party since the price was last fixed may be invoked by the party required to assume them.
Account shall also be taken of the terms on which the price previously applicable was originally fixed.
