Do I need a building consent?

A Building Consent is required for most building work, this includes alterations and additions and includes the following:

  • structural building - additions, alterations to existing buildings and demolition
  • new buildings
  • decks, platforms or bridges more than 1.5 metres above ground level
  • retaining walls higher than 1.5 metres

  • installing a fireplace or air conditioning system
  • fences or walls higher than 2.5 metres

As a building owner, you are responsible for ensuring any exempt building work complies with the Building Code and that it doesn't breach any other Act.

Although the work may be classed as exempt under the Building Act, other approvals such as resource consent may be required under the Resource Management Act 1991. If you're not sure about other approvals, please phone us on 0800422522 and talk to one of our planners.

There are exceptions where a Building Consent is not required. See our Exemptions Page for more detail.
