To the full extent permitted by law, employees of the Bureau shall have free
access, at proper hours of the day, to all parts of buildings and premises for
the purpose of inspecting the condition of the water pipes and plumbing fixtures
to determine whether cross-connections or other structural or sanitary hazards
exist, and the manner in which the water is being used. Whenever the owner of
any premise supplied by the Bureau restrains authorized City employees from
making such necessary inspections or refuses access therefor, water service may
be refused or discontinued.
