ACT Building Contracts: What to Check Before You Sign

The ACT has fewer mandatory building contract protections than most states — no required written contract, no cooling-off period, no legislative deposit cap. That makes it even more important to understand what you're signing and to protect yourself through careful negotiation and documentation.

This guide covers what to know before signing a building contract in the ACT, what industry practice looks like, and where to go if things go wrong. We're not lawyers and this isn't legal advice.

How the ACT is different

Unlike NSW, Victoria, or Queensland, the ACT does not have a standalone domestic building contracts Act with deposit caps, cooling-off rights, and mandatory contract forms. Consumer protection comes through:

• General contract and consumer law
• Building and planning compliance via Access Canberra
• ACAT for civil disputes
• Master Builders Fidelity Fund (MBFF) for limited insurance cover

This means you bear more responsibility to negotiate fair terms before signing — the law won't automatically cap your deposit or give you five days to change your mind.

What to insist on — even though it's not mandated

Written contract

Not legally required, but essential. Insist on a written contract covering:

• Scope of work — plans, specifications, inclusions, exclusions
• Contract price and payment schedule
• Completion timeframe
• Variation procedure
• Dispute resolution process
• Warranties and defects liability period

Deposit

No legislative cap. Industry practice is typically up to 10% of the contract price. Before agreeing:

• The maximum claim under MBFF insurance is currently $10,000 if work is not completed — so a deposit above this leaves you exposed
• Negotiate the lowest deposit the builder will accept
• Don't pay until you're confident the builder can deliver

Progress payments

Good practice: payments tied to completed work, not calendar dates. Apart from the initial deposit, each progress payment should cover only work already done. Check the contract states this explicitly.

No cooling-off period

There is no cooling-off period in the ACT. Once you sign, you're bound. This makes pre-signing legal review critical — not optional.

Building certifier

Your building certifier (not your builder) is responsible for building and planning compliance. For compliance issues during construction, contact Access Canberra or your certifier.

MBFF insurance

If your builder is a Master Builders member with MBFF cover, understand the limits. For MBFF policy holders, the Consumer Law Centre may assist: carefcs.org.au

Clauses to watch in your ACT contract

Extensions of time — HIA and MBA ACT contracts include broad extension grounds. Track and dispute in writing.

Variations — Insist on written, priced approval before work — even though ACT law doesn't mandate it the way QLD does.

Practical completion — Don't sign until you've inspected thoroughly.

Scott Schedule — If a dispute reaches ACAT, defect claims often require a Scott Schedule itemising each issue. Document defects from day one.

Before you sign — ACT checklist

• Written contract (insist on it, even though not mandated)
• Builder's licence and credentials verified
• Deposit negotiated — consider MBFF $10,000 claim limit
• Progress payments tied to completed work
• Legal review before signing (no cooling-off safety net)
• All plans and specifications attached
• MBFF or other insurance understood
• Special conditions on completion date and variations

Frequently asked questions

Is a written building contract required in the ACT?

ACT legislation does not mandate a written contract for residential building work — but it is strongly recommended. A verbal agreement leaves you with almost no protection if things go wrong.

Do I have a cooling-off period in the ACT?

No. The ACT has no mandatory cooling-off period for building contracts. Once you sign, the contract is binding. Get legal review before you sign, not after.

Is there a deposit cap in the ACT?

No legislative deposit limit. Industry practice is typically up to 10% of the contract price. Negotiate the deposit carefully — the maximum you can claim under Master Builders Fidelity Fund insurance is currently $10,000 if work is not completed.

What insurance applies in the ACT?

The Master Builders Fidelity Fund (MBFF) provides limited cover for members' projects. Check whether your builder holds MBFF insurance and understand the claim limits before paying a deposit.
