Does an NT Floor Coating Job Need a Registered Builder? in Darwin

The Building Practitioners Board says anyone intending to carry out building work in the Northern Territory must be registered with it as a Building Contractor, and its page lists renovations or alterations to existing buildings where there is no increase in the floor area or height among work that does not require a registered builder. Its page does not mention epoxy or floor coatings.

What a registered builder for floor coating in Darwin actually involves

Permits are separate: the Board's home page adds that these exclusions do not alter the requirements for building permits. Among work that requires a registered building contractor, the page lists work where the cost is above A$25,000 for prescribed residential building works. It does not say what is prescribed, or whether a floor coating is.

What we cannot say

Whether a floor coating is building work at all. The page does not mention epoxy or resin coatings, so we make no statement about it either way.

A spirit level and a hand trowel on a bare concrete garage slab with a roller door open behind — registered builder and floor coating, Darwin. Illustrative example.

What to ask

Ask the contractor what registration they work under, and ask the Board whether the job is building work. Ask the Board or your council whether a permit applies, because the exclusions on the Board's page do not decide that. The main page sets the other Territory lines beside it, and the quotes page covers what to put in writing.

These lines are Territory-wide, so they read the same in Darwin, Palmerston and every suburb on this site. No Darwin or Palmerston council page was read for this one, so ask your council about permits.
