Health & Saf. Code, § 18870.7

A permit to operate shall be issued by the enforcement agency. A copy of each permit to operate shall be forwarded to the department. A permit to operate shall not be issued for a park when the previous operating permit has been suspended by the enforcement agency until the violations that were the basis for the suspension have been corrected. Any park that was in existence on September 15, 1961, shall not be denied a permit to operate if the park complied with the law that this part directly or indirectly supersedes. A permit to operate shall be issued for a 12-month period and invoiced according to a method and schedule established by the department. The invoice shall provide notice of the Mobilehome Residency Law (Chapter 2.5 (commencing with Section 798) of Title 2 of Part 2 of Division 2 of the Civil Code) and the Recreational Vehicle Park Occupancy Law (Chapter 2.6 (commencing with Section 799.20) of Title 2 of Part 2 of Division 2 of the Civil Code), as applicable to the park. Permit applications returned to the enforcement agency 30 days after the due date shall be subject to a penalty fee equal to 10 percent of the established fee. The penalty fee for submitting a permit application 60 or more days after the due date shall equal 100 percent of the established permit fee. The penalty and the established permit fee shall be paid prior to issuance of the permit, and the fee and 100 percent penalty shall be due upon demand of the enforcement agency for any park that has not applied for a permit.
