(1) The fact that a local authority may have approved, with or without tests, plans, excavations, foundations, the construction of structural members or any other aspect of any building or sewerage work does not, per se, exonerate the owner, builder or plumber from all liability in respect of such work.

(2) The owner, builder or plumber remains responsible in all circumstances for complying with the provisions of these model building by-laws, as adopted by any local authority.

(3) The local authority will not be responsible for any costs or losses associated with the construction of buildings or sewerage work unless such costs or losses can be directly attributed to the wrongful or negligent acts of the local authority or its servants.
