Commercial building contractor registrations

As part of a reform program to increase confidence in the construction industry by ensuring commercial builders have appropriate qualifications and experience, the Northern Territory Government has introduced registration requirements for commercial building contractors who undertake class 1b and classes 3 to 9 building work.

A grandfathering initiative has been introduced to bring experienced and skilled builders into the registration scheme and allow them to continue to work as usual.
