Important Changes to the BIA Website

The content previously available on the Building Industry Authority website ( is now located within the Department of Building and Housing website:

How do I find the 'old BIA' information?

Simply go to and click on the link 'Building Controls' beneath the Department's logo. This will take you to the Building Controls section of the Department’s website.

You will notice that the layout and structure of building controls information is very similar to the layout of the former BIA website. The aim is to minimise disruption to users who were familiar with that site.

Content has been updated to reflect the fact that the BIA was dissolved on 30 November 2004, and its building control functions transferred to the Department of Building and Housing.
