Schedule 1: Building work that does not require a building consent

Find out which building projects usually don't require a building consent, including examples, exceptions and who is authorised to do the work.

The purpose of Schedule 1: Building work for which building consent is not required is to exempt building work that is low-risk from requiring a building consent, because the costs associated with obtaining a consent are likely to outweigh any benefits that requiring a building consent may offer.

Schedule 1 exemptions are generally for building work that will not affect the building’s structure or fire safety and that do not pose a risk to public safety.

Note that Schedule 1 exemption 2, is the only case which requires a decision from regional or territorial authorities. This allows them to use their discretion in exempting any type of building work from requiring a building consent.

The following table lists the Schedule 1 exemptions. We provide the text of the legislation, guidance and examples for each of these in turn.
