When do you need a Building Permit ?
A Building Permit is required for all major building projects including new homes, home extensions, garages and commercial projects. A permit is also required for many small projects including sheds, retaining walls, fences, decks, carports, verandah’s, swimming pools and spas.
How Do I Get a Building Permit?
A building surveyor is responsible for issuing a Building Permit at the commencement of a building project.
The surveyor should be engaged at the very start of the process, and can advise on documentation necessary to obtain the permit.
After the Building Permit is issued, the building surveyor will carry out a series of inspections at different stages throughout the project to ensure that the building work meets minimum standards.

Changes to domestic building insurance
As of 1 July 2014, builders will need to provide domestic building insurance when the cost of building work is greater than $16,000 (previously, insurance was needed for building works greater than $12,000). This will save costs for relatively small projects and reduce regulatory burdens on businesses.
Domestic building insurance will now cover up to $300,000 (up from $200,000) to fix structural defects for six years, and non-structural defects for two years. This will provide coverage more in line with current building costs.
