Iowa Admin. Code r. 661-503.2
If a complaint alleging an act or acts in violation of Iowa Code chapter 103, rules adopted by the board, or any other provision of law deemed relevant by the board to the use of a license issued by the board is substantiated, the board may suspend the license for a specific period of time, or indefinitely, may revoke the license, or may reprimand the licensee. The holder of a license which is suspended or revoked will be notified of the suspension or revocation in writing by registered mail, return receipt requested, or by personal service. The notice will include a statement that the licensee has the right to appeal the reprimand, suspension or revocation to the board within 30 days of receiving the notice, and that the reprimand, revocation or suspension will not take effect until the time to file an appeal has expired. If an appeal is filed, the reprimand, suspension or revocation is stayed until the appeal has been acted upon. The suspension of revocation becomes final 30 days after delivery of the notice if a timely request for an appeal is not received by the board.
EXCEPTION: If the board finds that a violation which is the basis of the suspension or revocation is such that allowing the licensee to continue to engage in work covered by the license would present an imminent threat to the safety of the public, the board may provide that the suspension or revocation take effect immediately upon notice being delivered to the licensee.
