You must have the completed, original 30 Day Notice of Termination of Tenancy and the lease agreement (if you have one). A rental agreement is short period tenancy often around 30 days and the contract is renewable after the tenancy period.For example, if you seek information about the rental agreement, look under "Rental Agreements and Leases" in the. "BEFORE YOU AGREE TO RENT" section. GLOSSARY. No. That only applies to renewing the lease or month to month leases. You need to let them complete their lease, voluntarily terminate their lease early. Under state law in California, your landlord must give you reasonable notice in writing before entering your rental. While 30 days is required absent other agreement, the CA rental agreement can require notice of intent to vacate be given on a specific day of the month. If you used to have a lease, and now it has gone monthtomonth, a simple 30day notice is all that is required. A 30day notice is required if the tenant has lived in the unit for less than one year.
