Building work that does not require a Building Consent

The New Zealand Building Code 2004 Schedule 1 NZBC, 2004 provides this information.

Application for Exemption of work outside the requirements of Schedule 1 can be made to the Territorial Authority as described under Part 1 Section 2 of Schedule 1.

How long does it take to get a Building Consent?

Building Consent processing time depends on the complexity of your project and whether or not you have provided us with sufficient information.

All Building Consents are required to be approved within 20 working days, however; if information is deficient the statutory time clock is stopped and a formal request will be made for further information. The statutory time clock is not restarted until the requested information is received in full.

It is possible that your Building Consent application requires checking by several disciplines; therefore, the clock may be stopped on more than one occasion.
