The date of renewal, renewal interval and renewal fee is established by the director of the department of licensing in accordance with chapter 43.24 RCW.

A completed application for renewal requires payment of a fee, and any information specified by the board in the renewal notice. For a professional land surveyor the renewal application requires completion of professional development requirements. If a completed application for renewal has not been received by the department by the date of expiration (postmarked before the date of expiration if mailed or transacted online before the date of expiration), the license is invalid. Renewals that remain expired over ninety days past the date of expiration require payment of a penalty fee equivalent to the fee for a one-year renewal in addition to the base renewal fee. The licensee is responsible to ensure timely renewal whether or not they received a renewal notice from the department.

The licenses for individuals registered as professional engineers or professional land surveyors shall be renewed every two years or as otherwise set by the director of the department of licensing. The date of expiration shall be the licensee's date of birth. The initial license issued to an individual shall expire on the next occurrence of his or her birth date. If the next birth date is within three months of the initial date of licensure, the original license shall expire on his or her second birth date following original licensure.
