These repair and maintenance clauses may be included in a commercial lease specify the obligations of each of the landlord and tenant. These clauses include practical guidance and drafting notes indicating when to use each clause. A clause dealing with repair and maintenance is normally included in a lease because the local rules of law do not generally reflect the customs in the trade. Moreover, this is an area in which there must be clear guidelines defining the immediate obligations of the parties, since the curing of a defective physical condition often cannot await a protracted dispute as to responsibility. The capitalized terms and section references used in this clause should be conformed to those used in the relevant commercial lease.
