Wash. Rev. Code § 47.42.120
Notwithstanding any other provisions of this chapter, no sign except a sign of type 1 or 2 or those type 3 signs that advertise activities conducted upon the properties where the signs are located, may be erected or maintained without a permit issued by the department. Application for a permit shall be made to the department on forms furnished by it. The forms shall contain a statement that the owner or lessee of the land in question has consented thereto. For type 8 signs (temporary agricultural directional signs), when the land in question is owned by the department, the consent statement must be reviewed and, if the sign does not create a safety concern, be approved within ten days of application by the department. The application shall be accompanied by a fee established by department rule to be deposited with the state treasurer to the credit of the motor vehicle fund. Permits shall be for the remainder of the calendar year in which they are issued, and accompanying fees shall not be prorated for fractions of the year. Permits must be renewed annually through a certification process established by department rule. Advertising copy may be changed at any time without the payment of an additional fee. Assignment of permits in good standing is effective only upon receipt of written notice of assignment by the department. A permit may be revoked after hearing if the department finds that any statement made in the application or annual certification process was false or misleading, or that the sign covered is not in good general condition and in a reasonable state of repair, or is otherwise in violation of this chapter, if the false or misleading information has not been corrected and the sign has not been brought into compliance with this chapter or rules adopted under it within thirty days after written notification. Beginning July 1, 2014, the department shall establish and charge by rule an annual fee for type 4 and 5 sign permits. The fee must reasonably recover costs for outdoor advertising control program administration and enforcement and may not exceed one hundred fifty dollars. The department shall establish by rule exemptions from payment of the annual fee for type 4 and 5 signs that do not generate rental income.
