A seven day notice is used to demand payment of rent that is due and owing. This legally notifies a tenant that; if rent is not paid within seven days after receiving written notice of nonpayment, the rental agreement will terminate.
A fourteen day notice is used for all other lease violations (for example, causing damage to the property). This legally notifies a tenant that; if the violation is not corrected in fourteen days, the rental agreement will terminate thirty days after receipt of notice.
A thirty day notice is used to terminate a month-to-month tenancy. A landlord may terminate a month-to-month tenancy by giving written notice to a tenant at least thirty days before the start of a new monthly term.
