It shall be the duty of the Zoning Administrator to enforce this chapter. If the Zoning Administrator shall find that any of the provisions of this chapter are being violated, he shall notify in writing the persons responsible for such violations, indicating the nature of the violation and ordering the action necessary to correct it, and shall take such other action as is authorized by law to ensure compliance with or to prevent violation of its provisions.

Every department and employee of the City authorized to issue permits or licenses effecting the use or occupancy of land or of a building or structure shall comply with the provisions of this chapter. Where any action on referral or on appeal is required by this chapter, no such permit or license shall be issued unless and until such action has been taken and the time within which an appeal could have been taken has expired. If any proposed building or structure, use or occupancy for which a permit or license is sought conforms with this chapter in all respects, the application therefor may be approved as to zoning; and otherwise it shall be denied. Any such permit or license hereafter issued contrary to the provisions of this chapter shall be void and of no effect.

Whenever there is doubt as to the classification of a use not specifically mentioned in this chapter, the determination shall be made by the Zoning Administrator. The Administrator shall make such investigations as are necessary to compare the nature and characteristics of the proposed use with those of listed uses in the various districts, and shall determine that the use is, in all essentials, pertinent to the objectives of this chapter, of the same character as a use listed as a permitted or as a conditional use in one of such specified district or districts. No use added by such administrative determination shall include, among the uses permitted in any district, a use which is specifically the same as one first permitted in a less restricted district. The determination of the Zoning Administrator shall be final unless an appeal is taken, as hereinafter provided.
