FAQ

Frequently asked questions often relate to permits – everything from do I need one, to what’s the cost, and how long will it take. Naturally, every design project is unique so permit requirements can differ, but the following FAQ post will provide you with an introduction to planning and building permits when it comes to prefabricated modular homes.

Like a conventional build project, permits are required to build a modular home. Regardless of whether you are building on-site with a slab or constructing a prefab home in a factory and transporting it to the site, the permit process is very similar.

There are two main types of permits required for any residential construction project – the Planning Permit and the Building Permit. The two permits vary state-by-state but essentially the terms mean the same – one is a legal document issued by your local council providing permission for development, and the other relates specifically to the carrying out of building construction.

Not all modular house projects require a Planning Permit. A Planning Permit allows land to be subdivided, developed, or used for a particular purpose. Planning Permits are issued by your local council in accordance with a planning scheme.

Firstly every state is different, so it’s best to give us a call so we can give you the actual requirements, but in general, the process is similar, the Planning Permit is known as a Development Application (DA). There is also a fast-track approval process applicable to some new builds and modular projects. Providing the application meets specific criteria, it can be determined by a council or accredited certifier without the need for a full development application. This is known as a Complying Development Certificate (CDC).

The requirements for a CDC are a more universal set of requirements, applicable across most states, as the title suggests, must be in compliance with specific criteria such as floor size, building heights, site coverage controls and block size. The requirements for a DA will vary between councils.

Our knowledgeable team will review and assess your site and will recommend the method that is best suited for your new prefab home.

The best and quickest way is to give us a call and we can advise in regards to your specific needs. For example, If your site is in Victoria, you can go to the Land Channel and search using your address. Free basic property reports are provided and they are usually sufficient to establish whether you’ll need to obtain a Planning Permit.

The report will stipulate whether there are any overlays present on your site. Examples of possible overlays include Bushfire Management Overlay, Heritage Overlay, Neighbourhood Character Overlay, and Significant Landscape Overlay. Some blocks of land may have more than one overlay in place.

If an overlay applies to your site, there is an increased likelihood that a Planning Permit will be required.

If you are not sure whether you require a Planning Permit for your prefab home, you can always contact the planning department of your local council.

The New South Wales equivalent is the New South Wales Planning Portal website. Here you can check which planning controls apply to your property.

If a Planning Permit is required, then there is the cost to undertake the documentation for the application. We will provide you a quote for this when we have the specific information

There is also a cost involved in lodging an application with your local council as well as any external consultant costs that may be required to provide supporting documentation. We can assist you here and undertake the process of obtaining the planning permit and supporting documentation. Alternatively, you may wish to undertake this process yourself.

The cost is highly dependent on the degree of documentation required varies state by state and by each local council. provides, the reports requested by the council and the external consultants we many need to engage. 

Planning approvals generally take two to three months from the time you submit an application. Depending on your council they can take longer.

The approval process time is typically four to six weeks. While this can be seen as a quicker option in getting your new home built, it is a very black and white process that may see some compromise in achieving your desired design outcome.

In all cases, if the application is unsuccessful, you can appeal the matter to a Civil and Administrative Tribunal (VCAT in Victoria; NCAT in New South Wales.) This process can take several months to reach a resolution.

A Building Permit, also known as a Construction Permit, is a document issued by an independent and registered building surveyor. The surveyor assesses the plans and documentation for the proposed building ensuring the design meets the requirements of the Building Code of Australia, The Building Act 1993, and the Building Interim Regulations 2017.

Regardless of whether you construct a prefabricated home or a traditional site-built home, a Building Permit is always required.

A Building Permit provides approval for construction work to commence and is required for most new homes, alterations, and extensions.

If a Planning Permit is required for your modular house project, it must be obtained before a Building Permit can be issued.

A Planning Permit does not remove the need to obtain a Building Permit. A Building Permit will always be required when building your new home.

We can help organise this for you and the cost is included in the design consultation price.

Following the signing of the purchase agreement for your new home, we will arrange for a registered building surveyor to issue the Building Permit. Building Permits are typically issued within four weeks. See the timeline for the process here.

There is one final permit required once construction is complete. An Occupancy Permit, also known as an Occupation Certificate, will be issued by an independent and registered building surveyor. The Occupancy Permit indicates that the surveyor is satisfied with the works and that your new home is suitable to occupy from a health and safety perspective.

For extension projects, a Certificate of Final Inspection will be issued rather than an Occupancy Permit, as the existing building should already have one. Again, this is issued by the surveyor.
