The date on which a tenant's obligation to pay rent begins, which may differ from the lease commencement date when the tenant receives free rent or a build-out period before paying full rent.
The rent commencement date is one of the most critical dates in a lease and frequently differs from the possession or lease commencement date. When a landlord grants free rent at the start of a lease, the tenant takes possession on the commencement date but does not begin paying rent until the rent commencement date. For example, a tenant might take possession January 1 (lease commencement) and begin paying rent April 1 (rent commencement) after a 3-month free rent period. Lease abstracts must capture both dates separately. If the rent commencement date is tied to substantial completion of tenant improvements, the abstract must note that contingency and its impact on the overall rent schedule.
