When you need a written contract

You need a written contract if you're carrying out domestic building work priced over $3,300 including labour, materials and GST.

If the work is priced at  $20,000 or more, before the owner signs the contract, the building contractor must give them a copy of the:

 QBCC consumer building guide—version 3 (PDF, 74KB)

This guide provides general information for home owners about:

  • key building and contract issues
  • how to avoid or handle disputes
  • common pitfalls.

The contractor should ask their client to read, sign and date the guide as evidence that the contractor has met this obligation.

What is domestic building work?

Domestic building work includes:

  • building a new detached dwelling (including a duplex)
  • building a structure associated with a home such as a shed, garage, carport, retaining structure, driveway, fence, workshop, swimming pool or spa
  • removing or re-siting a dwelling intended to be used as a residence
  • renovating, extending, altering, improving (including painting and installing services) or repairing a house, duplex or unit
  • refitting a kitchen or bathroom, and
  • landscaping, paving, site work, etc.

Before you sign a contract

You should carefully check the contract papers, including any associated plans and specifications. If you have any questions or concerns you should seek legal advice before signing. 

To be valid, the contract must

  • in writing
  • be signed and dated by each party or their authorised representative
  • comply with Schedule 1B of the QBCC Act.

Read our guide below containing general information about domestic building contracts and the relevant Queensland legislation.

Which contract to use

To comply with the relevant Queensland legislation, you have a few contract options:

  • use one of our contracts
  • use a contract developed by a major industry association
  • develop your own contract—but you must obtain legal advice to ensure it is compliant.

The QBCC produces a range of domestic  building contracts which include all forms and schedules necessary to enable you to conveniently document and carry out your building project.

A warning about developing your own contract

If you want to use your own written agreement, it’s essential you get legal advice first. You risk prosecution, fines, and financial loss if you go ahead without making sure that it complies with the Queensland legislation.

For the construction of an entire home

If you're building a single house or duplex, we recommend using the QBCC new home construction contract.

For new home contracts, contractors must give homeowners a copy of:

  • a QBCC-approved consumer building guide before the homeowner signs the contract
  • the signed and dated contract within 5 business days of entering the contract (including any plans and specifications)
  • the commencement notice (included in the contract pack) within 10 business days of work starting on site. The notice advises the date:
    • work commenced
    • for practical completion.

Warnings

Warning about using your own contract

If you want to use your own written agreement, it’s essential you get legal advice first. The contract requirements for domestic building work are much more detailed than the contract requirements for commercial work. You risk prosecution, fines, or financial loss if you go use a contract without making sure that it complies with the Queensland legislation.  

Warning against using old or interstate subcontracts

Recent changes to relevant Commonwealth and State legislation can make it inappropriate or even legally dangerous to use older contracts or contracts produced in a different jurisdiction (e.g. contracts from a different State or even from overseas).

Termination rules

The QBCC strongly recommends that, before signing, contractors seek legal advice regarding the termination clauses of any contract they intend to use for building work. Termination of any contract is a significant step which should not be taken without prior legal advice from an experienced lawyer.

Offence to not put contract in writing

A contractor commits an offence if they don't use a written contract which complies with the requirements of the QBCC act for regulated building. QBCC may prosecute or take disciplinary action and apply demerit points. This can lead to loss of licence, potential fines and financial loss for the contractor.
