A Standard Clause for use in a commercial lease. This Standard Clause defines the commencement date of the lease and provides for the delivery of possession of the premises by the landlord to the tenant when the landlord's work is substantially completed. This Standard Clause favors the landlord but contains integrated notes with important explanations and drafting and negotiating tips for landlords and tenants. While commercial real estate leases are generally governed by state law, this jurisdictionally neutral Standard Clause is useful and relevant in every state.
