Modular homes and prefabricated buildings include pods, tiny homes and outbuildings.
You should check if you need council approval or a building permit before investing in a modular home. You may also need to use a registered builder.
Checks what approvals are needed
Watch out for misleading claims about prefabricated buildings being "DIY" or "permit-free". You still need to meet planning, safety and building requirements.
Contact your local government authority to check:
- what approvals or permits you need
- whether you need to use a registered builder or be an approved owner-builder.
You may need a registered builder or be an approved owner-builder when a building permit is required and:
- a habitable building is valued at more than $20,000
- a non-habitable building, such as a shed, is valued at more than $50,000.
A licensed tradesperson must carry out any electrical or plumbing work.
Ask the supplier for written confirmation that the building and work will meet all legal and regulatory requirements.
Deposits
You should only pay a small deposit upfront to secure the contract.
Negotiate with the builder to make progress payments based on key stages of the work.
For example, payments could be linked to:
- delivery of materials
- manufacturing stages
- installation work.
Ask for evidence of completion of the agreed stage of work before making a progress payment.
For example, do a site visit to check your materials or the progress of your home.
