The following regulations shall apply to every use for which a use permit was lawfully issued pursuant to the provisions of this title which were in effect prior to the effective date of the ordinance codified in this chapter.

    A.    If the use, as permitted by the conditions of the use permit, exists and is listed herein as a permitted use in the district under the same conditions, such use shall be lawful and approved as to zoning, subject to those same conditions.

    B.    Where the land involved has been developed under such use permit, and is by the terms thereof more restricted than by the regulations of this title for the same type of building or use, such restrictions, to the extent that they could have been imposed under the provisions of this title governing conditional use, variances or the approval of site development shall remain in full force and effect.

    C.    Where the parcel has been developed in accordance with the terms of such a use permit for a use permittee thereunder but not hereafter permitted in the district, the use shall be deemed to be a permitted use for the time period of such use permit, and all the terms and conditions of the use permit shall continue in force, subject to the provisions of Section 17.52.640.
