An inspection warrant shall be supported by an affidavit, particularly describing the place, dwelling, structure, premises, or vehicle to be inspected and the purpose for which the inspection is made. In addition, the affidavit shall contain either a statement that consent to inspect has been sought and refused or facts or circumstances reasonably justifying the failure to seek such consent.
