It's permissible for you to sublease, as long as you get your landlord's consent. In fact, subletting in the residential context, without landlord written consent, can be an incurable breach of the lease potentially leading to an eviction.The best clause from a tenant's perspective is one that grants the tenant the right to assign or sublet freely without landlord's further consent. Under California law (for leases signed after September 1983) a landlord cannot unreasonably withhold consent to a sublease or assignment. Subleasing is legal in California unless prohibited or limited in your lease agreement. A sublease transfers the tenant's right to part or the entire premises. Whether the landlord's consent has been unreasonably withheld in a particular case is a question of fact on which the tenant has the burden of proof. Under California law (for leases signed after September 1983) a landlord cannot unreasonably withhold consent to a sublease or assignment. Read Section 2938 - Assignment of interest in leases, rents, issues or profits of real property, Cal. Civ. A bad subtenant or assignee can wreak a lot of havoc in a short amount of time or even refuse to leave once the lease or rental agreement is up.
