A Lease Agreement — Commercial (also known as a Commercial Lease, Business Lease, or Office Lease) is a written contract between a landlord and tenant for renting commercial space. The agreement outlines the terms and conditions of the lease, including the amount of rent, the length of the lease, and any additional services that are provided. The landlord and tenant are both legally bound by the terms of the agreement, and any violation of the contract can result in legal action. There are three main types of Lease Agreement — Commercial: Triple Net (NNN), Modified Gross, and Full Service. A Triple Net (NNN) lease requires the tenant to pay for all operating expenses, such as taxes, insurance, and maintenance. A Modified Gross lease requires the tenant to pay a portion of the operating expenses, while the landlord pays for the remainder. A Full Service lease requires the landlord to pay for all operating expenses.
