Permits, licenses or registrations issued under this chapter expire one year after the effective date of issuance unless otherwise stated thereon, and may be renewed if the applicant complies with this chapter. A registration, permit or license must not be transferred, except that if the holder dies, an executor, administrator or heirs may operate under the existing registration, permit or license. The Director may assign new dates of licensure to existing licenses to effectively stagger annual renewals evenly throughout the year and must adjust license fees pro rata.
