For the listed residential work valued at $25,000 or above, check the Northern Territory Building Practitioners Board's Residential Restricted or Unrestricted registration scope. Restricted covers specified detached housing and attached Class 1a or Class 2 buildings of one or two storeys; Unrestricted extends the attached-building scope to any height. Registration, building permits and certification are separate checks, so match the job to the class and conditions before quoting.[1][2][3]
Residential Restricted and Unrestricted
From 1 October 2026 the qualifications, experience and insurance for each category are set by Ministerial Determination No. S79, gazetted that day. The class itself is defined by building type, height and work value.
| Class | Building types | Work value |
|---|---|---|
| Residential Restricted | Class 1a detached houses; attached Class 1a or Class 2 buildings of one or two storeys; attached Class 10 built at the same time as those buildings; retaining walls on which their integrity depends | $25,000 or above |
| Residential Unrestricted | Same scope, but attached Class 1a and Class 2 of any height | $25,000 or above |

Commercial classes are separate
The Board also lists new commercial classes. Restricted covers Class 3 to 9 buildings of up to three storeys, Class 1b and associated Class 10 work, and Unrestricted covers any height. Do not apply the residential scope to commercial work or the reverse.

Registration, permits and certifiers are different questions
The NT Government's residential table treats the building permit, the contract, insurance and the registered builder as separate items. A new house, associated structures, a relocation and a supporting retaining wall are listed as needing a registered builder. A bathroom renovation that changes walls, fixtures or plumbing is listed as not needing a registered building contractor but does need a permit.
Building control areas also differ, so confirm the project with a certifier. Interstate builders can apply by mutual recognition for the equivalent NT category, but individuals only, and it is not automatic. A company is registered after an individual.
Scope check before quoting you can copy
This is our suggested check, not a Board form. Builders do not all hold the same class, so match each job to the class on the register.
