Iowa Code § 543B.28
Every license shall expire in multiyear intervals as determined by the real estate commission. A person who fails to renew a real estate broker's or real estate salesperson's license by the expiration date shall be allowed to do so within thirty days following its expiration, but the commission may assess a reasonable penalty. The commission upon the written request of the applicant on forms prescribed by the commission, and payment of the fee, shall issue a new license for each ensuing license period except as provided in section 543B.15, in the absence of any reason or condition which might warrant the revocation of a license after a hearing as provided in sections 543B.34 and 543B.35.
