The commercial lease agreement in California is a document used to lease real estate to a tenant who needs retail, office, or industrial space. As a landlord, a detailed lease is necessary to have a successful transaction with the tenant. California Rental Lease Agreements are written documents used for the establishment of a binding agreement in which a tenant agrees to pay rent in exchange for living or working in a rented property. Contracts are concluded between two (2) parties: a lessor (rental manager) and the tenant(s) (those who live or work in rental). The forms outline the legal responsibilities of landlords and tenants and aim to ensure that there is little or no confusion about the rental amount, incidental costs, repairs, contact methods and much more. .
