Lease of Commercial Building with Option to Renew is a type of real estate agreement in which a tenant leases a commercial building for a predetermined period, and then has the option to renew the lease at the end of the period. The tenant typically pays rent on a monthly basis and is responsible for all repairs, maintenance, and utilities associated with the building. The lease also outlines the terms and conditions associated with the renewal option, such as how much notice must be given and the amount of any increase in rent. There are two main types of Lease of Commercial Building with Option to Renew: Traditional Lease and Lease with Right of First Refusal. A Traditional Lease is a standard lease agreement that allows the tenant to renew their lease for a predetermined amount of time. A Lease with Right of First Refusal is an agreement that allows the tenant to renew the lease if they are the first to submit a written notice of intent to renew. In both cases, the tenant is responsible for all associated costs and must adhere to the terms and conditions outlined in the lease agreement.
