Planning and approval rules can make a significant difference to the cost, location and suitability of a small home. Requirements depend on the type of dwelling, the land, the proposed use and the rules that apply in your state or local council area.
Why planning rules matter
Before buying a granny flat, tiny home, modular home or transportable dwelling, establish whether it can legally be placed and used on your intended property. A home that is suitable for one block of land may not be permitted on another.
Planning restrictions can affect where a dwelling is located, its size and height, its setbacks from boundaries, access, parking, services and whether it can be occupied or rented separately.
Different homes may have different requirements
Granny flats and secondary dwellings
Rules may cover the size of the dwelling, the existing home, minimum land requirements, private open space, access and whether the secondary dwelling can be rented independently. Do not assume that approval for a second dwelling automatically permits every proposed use.
Tiny homes
A tiny home on wheels is not automatically exempt from planning or building requirements. Its classification, how long it stays on a property, whether it is connected to services and whether people live in it can all matter. A tiny home on a permanent foundation may be assessed differently.
Modular, prefab and transportable homes
Factory construction does not remove the need to check the proposed site. Depending on the dwelling and location, you may need planning approval, building approval, engineering documentation, compliant foundations and permission for delivery and installation.
Planning approval and building approval are different
Planning approval generally considers whether a proposed use or development is permitted on the land. Building approval considers whether the building complies with applicable building requirements. Some projects may need both, while others may follow a different assessment pathway.
Other requirements can include plumbing and drainage approvals, wastewater arrangements, bushfire or flood considerations, access permits and electricity connections.
How to check the rules before buying
- Identify the exact property. Record the address, zoning and any relevant overlays or restrictions.
- Describe the proposed dwelling. Explain its dimensions, whether it is on wheels or foundations, how it will be used and whether anyone will live in it permanently.
- Contact the local council. Ask which planning rules and approval pathways apply to that property and proposal.
- Check building requirements. Confirm the required approvals, certification, engineering and installation standards with the relevant building authority or qualified professional.
- Confirm services and site access. Check water, sewerage or wastewater, power, drainage, vehicle access and delivery constraints.
- Get written confirmation where possible. Keep responses, approvals, plans and conditions with your purchase records.
Where to find official information
Start with your local council’s planning department and the official planning and building authorities for your state or territory. Ask them to identify the rules that apply to your specific property and intended use.
General guidance is useful for understanding the process, but it cannot replace a property-specific assessment. Rules and approval pathways can change, so verify current requirements before paying a deposit or arranging delivery.
Frequently asked questions
Can I put a tiny home in my backyard?
Possibly, but it depends on the property, the dwelling’s classification, its intended use and local requirements. Ask your council before purchasing or installing it.
Does a transportable home need approval?
It may require planning, building or other approvals even if it was built elsewhere. Confirm the requirements for the destination property and the proposed installation.
Can a supplier guarantee council approval?
A supplier can provide plans and documentation, but approval depends on the applicable rules and the specific property. Verify claims independently with the relevant authorities.
Before you commit
Check the property, confirm the approval pathway, calculate the full project cost and obtain the necessary written advice before committing to a small home. A little research at the beginning can help prevent expensive delays later.
