Issuance of permits. It shall be the duty of the Zoning Officer or his designee to issue a building permit, provided that he is satisfied that the structure, building, sign, parking area and the proposed use conform to all requirements of this chapter and that all other reviews and action, if any, called for in this or any other ordinance and other municipal, county and state requirements have been complied with and all necessary approvals secured therefor. All building permits shall be issued in duplicate, and one copy shall be kept conspicuously on the premises affected and protected from the weather whenever construction work is being performed thereon. No owner, contractor, workman or other person shall perform any building operations of any kind unless a building permit covering such operation has been displayed as required by this chapter, nor shall he perform building operations of any kind after notification of the revocation of said building permit.
