Have your plan ready

Before checking whether you need a consent for your deck, you need to know:

  • dimensions of the project (height, total area)
  • location on property where the project will go
  • size of the property in square metres
  • total pre-existing building coverage on property
  • total pre-existing hard surfaces on property.

There will be an explanation on how to calculate these factors in the online consent tool.

Our tip

If your deck is close to a boundary, and you have the written approval from your neighbours, you can apply for a Deemed Permitted Boundary Activity.
This application replaces the need to apply for a resource consent.
You will still need to apply for a building consent, if required.

​How to check if you need a consent to build a deck


​Our online tool helps you check if you need a building or resource consent for your deck.

This tool does not apply to decks located above the ground floor or on a steep, sloping section.

Have your plans ready before you start.

It should take you about 10 minutes to complete.

You should know

If you plan to build a deck that is up to 1.5m high, you don't need a building consent but you may still need a resource consent, depending on the rules in the Proposed Auckland Unitary Plan.

If your deck is more than 1m high, it must have a handrail.

Your building work must:
  • comply with the Building Code, even if no building consent is needed
  • not damage public service drains if its foundations are close to the pipes.
