A city or county may not deny, refuse to issue, or condition the issuance of a business license or a permit to construct a new legal on-premises advertising display upon the removal, conformance, repair, modification, or abatement of any other on-premises advertising display on the same real property where the business is to be or has been maintained if both of the following apply:
(a) The other display is located within the same commercial complex which is zoned for commercial occupancy or use, but at a different business location from that for which the permit or license is sought.
(b) The other display is not owned or controlled by the permit applicant, and the permit applicant is not the agent of the person who owns or controls the other display.
