(1) Licenses for professional engineers, professional land surveyors, on-site wastewater treatment system designers, or certificate of competency holders (inspectors) shall be renewed every two years. The date of expiration shall be the licensee's birthday. The initial license issued to an individual shall expire no earlier than one year after the issue date.

(2) To renew your license, complete an application for renewal, pay the required renewal fee, and provide the information requested in the renewal notice and application form. This information may include email address or other contact information. In addition, you must disclose any criminal conviction or sanction against you including suspension, revocation, or restriction of your license by a licensing authority in any state, federal, or foreign jurisdiction pursuant to RCW 18.235.110 and 18.235.130.

(3) For a professional land surveyor the renewal application requires completion of professional development requirements and an attestation by the applicant that they have read chapters 58.09 RCW and 332-130 WAC as part of the renewal process.

(4) For a licensed on-site designer, the renewal application requires completion of professional development requirements as part of the renewal process.

(5) If a completed application for renewal has not been received by the board 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. Licenses that remain expired over 90 days past the date of expiration require payment of a late fee equivalent to the fee for a one-year renewal in addition to the base renewal fee and completing a renewal application.

(6) If your professional engineer or professional land surveyor license has been expired for five or more years, you must submit a renewal application and you will be required to take and receive a passing score on the board's law review examination. In the first year of reactivated practice professional land surveyors may be required by the board to collect an additional 15 professional development hours (PDH).

(7) Any on-site designer license that remains expired for more than two years will be canceled. After cancellation, a new application must be made in accordance with chapter 18.210 RCW to obtain another license.

The licensee is responsible for timely renewal whether or not they receive a renewal notice from the department.
