Owner Builder Rules / Council Regulations.
Owner Building and getting council approval maybe easier than you may think. Assembling a Cabin Life timber cabin is relatively easy, and you can save a lot of money by building one of our Granny Flats or Cabins as a DIY managed project.
If your Cabin or Granny Flats requires council approval, our best recommendation is to become an owner builder. You will need an owner builders’ licence and a white card. These are easily accessible by doing a quick online course.
Basically, an owner builder who does not have many building skills can manage the project by outsourcing the cabin build to a local builder or depending on your location, maybe our install team can be contracted to build it for you. You then manage the site to ensure it is built as required. You can save yourself a lot of money by doing parts of the building process yourself and outsource the rest to qualified trades.
All cabins come with plans, and a comprehensive DIY video series is on the website and you tube.
Here are the links to the NSW and QLD owner builder’s information.

Once you have received your Owner Builder certificate and permit, combined with your development application number from council, then you are ready to commence on the job site.
Summary Info for the New South Wales Regulations
On the 27 February 2009 State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the Codes SEPP), which has state-wide application commenced. This new Codes SEPP contains exempt development types and complying development types for certain types of development. Garden sheds that comply with certain guidelines are considered exempt developments. These guidelines are as follows.
To be exempt development the development must not be carried out on land that is an environmentally sensitive area. You don’t need permission from council to build or install cabanas, cubby houses, ferneries, garden sheds, gazebos and greenhouses if:
- There are no more than 2 per lot.
- If it is on land in rural zones RU1, RU2, RU3, RU4 and R5 – be no larger than 50sqm.
- If it is on land in all other zones – no larger than 20sqm.
- It is no higher than 3m above the ground level.
- If it is on land in rural zones RU1, RU2, RU3 and RU4 – be located behind the building line of any road frontage.
- It is set back a minimum of 900mm from each boundary.
- It is located in the back yard if your property is in a heritage conservation area or a draft heritage conservation area.
- If it is located adjacent to another building—be located so that it does not interfere with the entry to, or exit from, or the fire safety measures within, that building.
- It cannot be a shipping container.
- The disposal of any roof water must not cause a nuisance to adjoining owners.
- In residential zones, any metal parts of the structure are to be low reflective, factory pre-coloured materials.
- If your property is bushfire prone land and the structure is going to be located less than 5m from your house or a neighbour’s house the structure must be constructed of non-combustible materials.
Fire Ratings for Council Approval.
Our cabin kits can pass the rural fire service rating of BAL 12-19 by raising the kits 400mm above the ground on posts. 90% of our cabin kits are constructed this way.
We can also get our cabin kits to BAL29 by using the BCA approved “Fireshell” Bush fire protective coating. Click here to go to Exfire protective coating website. https://www.exfire.com.au/’
There are several flame retardant sealers on the market. If you are in a bushfire prone area, please contact us for more information.

CLASS 1 BUILDINGS OR STRUCTURES
Class 1 buildings are houses. Typically, they are standalone single dwellings of a domestic or residential nature. They can also be horizontally attached to other Class 1 buildings such as terrace houses, row houses, or townhouses. In these situations, they must be separated by a wall that has fire‑resisting and sound insulation properties.
The Class 1 classification includes two sub classifications:
Class 1a and Class 1b.
A Class 1a building is a single dwelling being a detached house; or one of a group of attached dwellings being a town house, row house or the like.
A Class 1b building is a boarding house, guest house or hostel that has a floor area less than 300 m2, and ordinarily has less than 12 people living in it. It can also be four or more single dwellings located on one allotment which are used for short-term holiday accommodation.
