Q&A with Technical Manager David Kyburz
Q. I have been building for about 20 years and hold a C class builders licence. I have been asked to quote on a small extension to a takeaway shop however I have been advised that I would not be permitted to do this building work.
A. This advice is correct.
The building certifier appointed for the building work would not issue a commencement notice for this building work because a shop is deemed a Class 6 building under the National Construction Code - Building Code of Australia (BCA) and as a C licenced builder you would only be permitted to undertake building work on class 1, 2 or 10a buildings.
Class 1, 2 or 10a buildings
Class 1 buildings are classified under the BCA as:
(a) Class 1a — a single dwelling being—
(i) a detached house; or
(ii) one of a group of two or more attached dwellings, each being a building, separated by a fire-resisting wall, including a row house, terrace house, town house or villa unit; or
(b) Class 1b —
(i) a boarding house, guest house, hostel or the like—
(A) with a total area of all floors not exceeding 300 m2 measured over the enclosing walls of the Class 1b; and
(B) in which not more than 12 persons would ordinarily be resident; or
(ii) 4 or more single dwellings located on one allotment and used for short-term holiday accommodation,
which are not located above or below another dwelling or another Class of building other than a private garage.
Class 2: a building containing 2 or more sole-occupancy units each being a separate dwelling
Class 10a — a non-habitable building being a private garage, carport, shed, or the like.
