Consent Applications Are Complex

Each council may have different requirements for submissions for a building consent. The list below is only an indication of what may be required.

To complicate matters, requirements are constantly being updated so you must check with your council.
Application forms can be uplifted from Council offices and most Council websites have them available as a downloadable pdf.

This list is not comprehensive but covers most of the exemptions pertaining to domestic situations. If you are unsure, ask your local council before doing any work.Building work that is exempt from having a building consent must still comply with the building code.

The BCA (council) will often request additional information to that supplied and the 20-day clock will stop until that information is provided to the BCA.

Important Information

Each BCA (Council) may have different requirements for how many sets of plans you have to submit – the list above is not exhaustive. Some require that plans are drawn to a particular scale. Check with your BCA.

The details provided in the documents listed in the checklist must be good enough to show that what is being proposed will meet the performance requirements of the Building Code. For example, the documentation should clearly show how the house will keep water out by giving ground clearances, balcony and deck details, and information about claddings, including flashings and guttering.

Each aspect of the Building Code requirements has to be covered in detail in the documents. If the documents are not full enough, the BCA will have to come back to you for further information. When this happens the 20-day clock stops and doesn’t restart until you return with the amended documents. This delays the whole process.
