A Standard Clause that defines the commencement date of a 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 tenant but contains integrated notes with important explanations and drafting and negotiating tips for both 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.
