Part III deals with accommodation for storage of Food in tenement houses,
which means any house occupied by any person of the working class, which
is wholly or partially let in lodgings or which is occupied by members of
more than one family.

should tenement houses exist at some future time within the district of the
Port of London Sanitary Authority, then Section 17 provides that—

Public Health London Act, 1891, shall apply and have effect in respect of
Part III of this Act, as if such section were expressly re-enacted in, and
in terms made applicable thereto.
