Residential Building Cover in the Northern Territory

What it is

The Northern Territory does not run a compulsory home warranty insurance scheme of the kind NSW, Victoria, Queensland, South Australia, Western Australia and the ACT run. There is no NT equivalent of the Home Building Compensation Fund. There is no state insurer standing behind residential building work and no insurance policy in the ordinary sense.

What the NT has instead is residential building cover, and it is delivered as a fidelity fund certificate. The scheme sits under the Building Act 1993 (NT). Fidelity Fund NT manages the fund and is currently the only provider in the Territory. The arrangement replaced the old Home Building Certification Fund, which insured residential building work between 1993 and 31 December 2012, from 1 January 2013.

The distinction is worth holding onto. A fidelity fund is a pooled industry fund that pays out when a member builder fails. It is not a contract of insurance. The cover is similar to home warranty insurance elsewhere in what it pays for, but it is a different instrument written against a narrower set of triggers.

The 30 March 2026 reset

Reforms to the framework commenced on 30 March 2026. Three things changed:

• the minimum prescribed value that triggers the need for a fidelity certificate rose from $12,000 to $25,000
• the timeframe for cover of non-completion of work now recognises any approved extension to a building permit
• a claim can be made within 90 days of either becoming aware of a defect or a trigger event occurring

These amendments apply only to fidelity certificates issued after 30 March 2026. Certificates already on foot keep their original terms, because applying the changes retrospectively would alter the liability attached to issued certificates and would hit the financial position of the fund.

What actually triggers a payout

A fidelity fund certificate responds where the builder:

• becomes bankrupt
• dies
• disappears
• has their registration cancelled by the Building Practitioners Board

The fourth trigger is one the NT has and most other jurisdictions do not. A builder who is alive, findable and solvent but who has been deregistered still puts the owner into cover.

The flip side is the case most homeowners actually find themselves in. If the builder has not died, disappeared, become insolvent or been deregistered, there is no fidelity fund claim. A solvent builder who will not come back and fix the work leaves the owner with the disputes pathway, not the fund.

What is covered and for how long

A fidelity fund certificate covers:

• the costs of transitioning to a new builder to complete the work
• rectifying non-structural defects in the first year after completion
• rectifying structural defects for six years after completion

One year of non-structural cover is short by national standards. Most mainland schemes run two.

Which work needs a certificate

Prescribed residential building work covers a new house, duplexes and townhouses, units in complexes up to three storeys excluding undercroft or underground parking levels, and renovations and extensions to those buildings. Additions and extensions need a certificate only where the work is worth more than $25,000 and increases the residential floor area.

Work outside the scheme includes:

• prefabricated houses
• flats above three storeys, excluding undercroft or underground parking levels
• garden sheds and fences
• a stand-alone bathroom renovation, unless it is done alongside other work that does require a certificate
• a retaining wall that is separate from and does not support a residential building
• commercial work, transportable buildings and government contracts

Converting a shed into a house, or enclosing a carport to form a habitable room, does require a certificate.

What an NT builder has to do

Registered builders apply to the fidelity fund for an annual level of cover and have to show the financial capability and the experience to carry the level they want. On top of that annual approval, the builder gets a certificate for every individual job that includes prescribed residential building work.

The certificate has to be in hand before the building permit is issued for the work, and before the builder demands any payment from the owner. There is no way to backfill it later.

Owner-builders in the NT also have to hold a fidelity fund certificate, to cover future owners for building defects. That cover only becomes available once the property is sold or transferred, and only if the owner-builder then goes bankrupt, dies, disappears or is deregistered.

Where no trigger event has happened and the work is defective or incomplete, the pathway is the Commissioner of Residential Building Disputes, who can mediate and make decisions about rectifying or completing work on the property.
