It shall be unlawful for any person to open or use, or allow or cause to be used any public or semipublic swimming pool for swimming or bathing purposes without having a current, valid permit to operate issued by the Health Officer. Application for such a permit shall be accompanied by an annual fee as adopted by the Tacoma-Pierce County Board of Health. Applications shall be made in writing to the Health Officer on a form to be provided by the department; provided, that the fee for any initial permit to operate shall be prorated on the basis of one-twelfth the annual fee for each remaining month in the year. The Health Officer shall inspect the proposed public or semipublic swimming pool and upon determination that such swimming pool complies with applicable rules and regulations and the provisions of this Chapter shall issue a permit to operate to such applicant. Permits to operate shall expire on December 31 of the year for which issued and shall be renewable upon like application and payment of the annual fee. Permits shall be valid only for the swimming pool for which issued, but upon application may be transferred without charge from person to person. Permits shall be posted conspicuously on the premises for which issued and shall be protected from the weather.
