Direct lease space is more expensive and more stable while sublease space is less expensive but shorterterm in nature. A sublease, without some direct agreement between landlord and subtenant, does not extend that waiver from the landlord to the subtenant.A commercial sublease occurs when a tenant assigns part or all of their lease to a new tenant. California law requires tenants to seek explicit, written permission from their landlords to sublet if it is not already allowed in the lease. You should read your lease to see if it allows you to sublet the rental unit. Subletting means that you rent the unit to someone else. Sublet and sublease are two different words for the same concept. The suffixes of each word, "let" and "lease," both mean to rent out a property. A sublease agreement is a contract made between a subtenant and a tenant, as opposed to a lease agreement, which is between a tenant and the landlord. The subtenant only has rights because of your lease.
