The Chief of the Fire Department, or any fire inspector, may, at
all reasonable hours, enter any public buildings, public structures,
or enter upon any public premises or portions thereof, for the purpose
of routine preventative inspections, in order to ascertain whether
conditions exist which are liable to cause fire, or whether any violation
of any law or order relating to fire hazards or fire prevention exists
or has occurred. The owner, agent, or occupant of any such public
premises who refuses to permit or prevents or interferes with any
entry into or upon the public premises by such fire inspector, or
interferes with any such fire inspection, shall be deemed guilty of
violating this section.
