Do I need council approval for a concrete slab?

If you are planning a new project it is essential to understand the building regulations and building approvals which are needed before you can start. Not all types of construction or renovation projects require building approval or permit. However, in Australia, there are many State legislation exemptions, for the size of the project, value or simply the nature. It is recommended that if in doubt research on whether council approval is required. Many projects can be completed without council approval; however, always check depending on which state you are located in. You may need to determine how thick a slab can be, whether you should use concrete slabs or stumps, and how much concrete you may need for your project before you receive approval or go ahead with your project.
