A commercial lease is a legal agreement between a landlord and a business tenant that outlines the terms for renting a commercial property, such as an office, retail space, or warehouse. This contract specifies details like the duration of the lease, monthly rent, and responsibilities for maintenance and repairs. These leases can vary widely in structure, including gross leases, where the landlord covers most expenses, and net leases, where the tenant pays additional costs like property taxes and insurance. Understanding the terms of a commercial lease is crucial for both parties to ensure a successful rental relationship.
