Guide · ACT building insurance

The warranties apply
whether or not you write them down.

In the ACT, residential building work over $12,000 carries statutory warranties under the Building Act 2004 even if the contract is silent on them, and above that threshold the builder must hold a residential building insurance policy or a fidelity certificate before work commences. This guide walks through the ACT settings as an ACT building contracts fact sheet sets them out: the cover, the warranties, who appoints the certifier, and what all of that means for how you run a job. General information, not legal or insurance advice, and the figures should be re-verified against current ACT regulations.

01 / The basics

In plain English

For residential building work over $12,000 on some residential buildings in the ACT, the builder must hold a residential building insurance policy or a fidelity certificate before work commences, and the home owner should obtain a copy for their own records. Home owners warranty insurance in the ACT covers only up to $10,000 for deposits, so the cover is narrow and the copy of the certificate the owner holds matters.

Alongside the insurance requirement, residential building work over $12,000 carries statutory warranties under the Building Act 2004 (ACT). These apply even if they are not stated in the contract: broadly, the work must be carried out properly, skilfully and in accordance with the approved plans. You cannot contract out of them, and a client can rely on them whether or not the contract mentions them.

What the statutory warranties cover, and what they don’t

  • The warranties require the work to be carried out properly, skilfully and in accordance with the approved plans.
  • Structural and non-structural elements have different warranty periods, so the tail on the work is not uniform.
  • The warranties do not apply to items such as paving, fences, retaining walls, outdoor pools, ponds and antennas.

Who appoints the certifier

In the ACT the landowner must appoint the building certifier, and the contract must not give the builder the right to appoint the certifier. If a contract you are asked to sign, or one you issue, purports to hand that appointment to the builder, it is out of step with the ACT requirement and should be corrected before signing.

A note on currency: the figures above, the $12,000 thresholds for the insurance requirement and for the statutory warranties, and the $10,000 deposit cover limit, are drawn from an ACT building contracts fact sheet. These thresholds and limits should be re-verified against current ACT regulations before you rely on them, as they change over time. This is general information, not legal or financial advice.

02 / The reality

Where builders get stuck

Assuming the warranties only apply if written in

The statutory warranties under the Building Act 2004 apply to residential work over $12,000 whether or not the contract states them. A contract that stays silent on warranties does not escape them; it just leaves you less clear about what you have already promised.

Starting work before the cover is in place

For work over $12,000 the residential building insurance policy or fidelity certificate must be held before work commences, and the owner should get a copy. Starting first and papering the cover later is the classic timing failure across building insurance requirements.

Letting the certifier appointment sit in the wrong hands

The landowner must appoint the building certifier, and the contract must not give the builder that right. A contract clause that gets this backwards is a problem to catch before signing, not after.

Losing the paper years after handover

Structural and non-structural elements carry different warranty periods, and a claim can be assessed against your work long after the job. Contracts, variations, the certificate copy and inspection records are your defence file; keep them retrievable for the full period.

03 / The fix

A workflow that holds up

  1. 01

    Re-verify the ACT thresholds before contracting

    Confirm the current $12,000 thresholds and the $10,000 deposit cover limit against current ACT regulations before you rely on them. The figures here are from a fact sheet and change over time.

  2. 02

    Put the cover in place before work commences

    For work over $12,000, hold the residential building insurance policy or fidelity certificate before starting, and give the owner their copy. Cover first, work second, on every qualifying job.

  3. 03

    Check the certifier clause

    Make sure the contract leaves the appointment of the building certifier with the landowner and does not purport to give it to the builder. Fix the clause before anyone signs.

  4. 04

    Archive the job for the warranty period

    Keep contracts, variations, the certificate copy, approved plans and inspection records retrievable for at least the applicable structural and non-structural warranty periods. A later claim is decided on records, not recollections.

04 / The tooling

How software helps

Nothing in a software platform changes the ACT rules, and none of it is insurance. What software changes is whether the records these requirements run on exist when you need them. Every pressure point above is documentary: holding the certificate copy the owner should have, showing what was built and to which approved plans, keeping variations clean so the job you delivered is the job on paper, and answering a warranty question from files rather than memory across different structural and non-structural periods.

A platform that documents claims and variations against each job, keeps costs and commitments tied to the work, and holds the job’s documents in one place is quietly building your evidence file as a by-product of normal work. Keeping cost and cashflow visible also helps the business stay solvent, which is the surest way to keep a warranty question from ever becoming a claim against a builder who is no longer around to answer it.

05 / In practice

Where VIABUILD fits

VIABUILD keeps the job documented and the cashflow visible.

VIABUILD keeps each job’s commercial history in one place: claims and variations documented against the job with a dated trail, costs and commitments in cost tracking, and the job’s documents, including the certificate copy the owner should hold, held against the job rather than in inboxes. Keeping cost and cashflow visible also means the business is less likely to drift toward insolvency, which is the situation warranty schemes exist to catch.

VIABUILD is not insurance and does not provide, arrange, price or advise on it, and it does not deal with the ACT scheme or affect your cover in any way. The figures above are from an ACT building contracts fact sheet, so re-verify the $12,000 thresholds and the $10,000 deposit cover limit against current ACT regulations, and treat this as general information, not legal or financial advice.

  • The certificate copy the owner should hold, kept with the job
  • Variations documented with a dated approval trail
  • Approved plans and records held against the job, not inboxes
  • Cost and cashflow visible to keep the business solvent
  • Records retrievable across the warranty periods
  • Not insurance; re-verify thresholds against ACT regulations

06 / FAQ

Common questions.

For residential building work over $12,000 on some residential buildings, the builder must hold a residential building insurance policy or a fidelity certificate before work commences, and the home owner should obtain a copy. Home owners warranty insurance in the ACT covers only up to $10,000 for deposits. These figures are drawn from an ACT building contracts fact sheet and should be re-verified against current ACT regulations. General information, not insurance advice.

Residential building work over $12,000 carries statutory warranties under the Building Act 2004 (ACT) even if they are not stated in the contract. Broadly, the work must be carried out properly, skilfully and in accordance with the approved plans. Structural and non-structural elements have different warranty periods, so the cover is not uniform in time. Re-verify the threshold against current ACT regulations.

The statutory warranties do not apply to items such as paving, fences, retaining walls, outdoor pools, ponds and antennas. That does not mean those items carry no obligations at all under the contract or general law, but they sit outside the statutory warranties described here. This is general information, not legal advice.

The landowner must appoint the building certifier, and the contract must not give the builder the right to appoint the certifier. If a contract you are signing or issuing purports to hand that appointment to the builder, it is out of step with the ACT requirement and should be corrected before signing.

Treat them as a starting point, not a settled answer. The $12,000 thresholds for the insurance requirement and the statutory warranties, and the $10,000 deposit cover limit, are drawn from an ACT building contracts fact sheet and should be re-verified against current ACT regulations before you rely on them.
