If the person entitled to possession of any building, premises or
part thereof refuse admittance thereto, the Bureau Chief or his duly
authorized representative, for the purpose of making an examination
or inspection of the premises, shall seek authorization by use of
an order to show cause or any other prompt legal means from any court
of competent jurisdiction. The moving papers shall recite that he
believes or has probable cause, said probable cause justified by a
valid public interest, to believe that by an inspection of certain
premises designated in his affidavit he will obtain evidence tending
to reveal the existence of violations of this chapter. If such probable
cause shall appear, the judge shall issue a warrant or order authorizing
the Bureau Chief or his representative to inspect the premises named
in the affidavit and designated in the warrant to obtain evidence
tending to reveal the existence of violations of this chapter.
