If a building permit or, if appropriate, a grading permit, expires without commencement of construction, then the fee payer shall be entitled to a refund, without interest, of the fees paid as a condition for its issuance, provided, however, that the portion of any fee revenue received by the city as reimbursement of its costs in administering the provisions of this chapter shall not be refunded. The fee payer must submit an application for such a refund to the city manager within ninety (90) calendar days of the expiration of the permit. Failure to timely submit the required application for refund shall constitute an absolute waiver of any right to the refund. (Prior code § 84.02.217)
