Such revocation or suspension shall be made in the following manner: The licensee shall be given seven days of notice that his or her license will be suspended or revoked, and the reason or reasons therefor, unless good cause is shown to the contrary at a hearing provided before the Construction Board of Appeals. Pending the hearing, the Building Official may forthwith suspend such license if the circumstances, in his or her opinion, justify such action.

   (n)   Conditions of Participation in Reciprocal Licensing. The licensing ordinance, examinations and examination procedures of such municipalities having a desire to participate in reciprocal licensing shall be substantially similar to the requirements set forth in this section, and their regulations governing the installation and maintenance of refrigerating systems shall be in substantial conformity with the provisions of this Building and Housing Code.

   (o)   Right to Participate in Reciprocal Licensing. The right of any municipality to participate in the reciprocity provisions of this section shall be determined by the Building Official, based upon qualifications outlined in this section.
