Updating the Building regularly helps ensure it keeps pace with modern construction methods, building uses, and technology. This includes updates to the Building Code clauses, acceptable solutions, verification methods, Building Product Specifications, and other published guidance information.
Update process
The Building Code is reviewed and updated every three years. The next update is scheduled for 2028.
In the past, updates happened on an ad-hoc basis. Moving to a regular three-year cycle makes the process more predictable. This helps everyone know when changes are coming and gives people time to have their say.
Topics for each update are recommended by engineers, architects and other technical experts in MBIE’s Building Performance and Engineering team. They consider current priorities, available resources, and feedback from the public.
Developing content for a Building Code change is a detailed process that can take several years. This is because it involves research, technical analysis, and consultation with experts to ensure the changes are safe, practical, and cost effective.
Before any changes are finalised, MBIE runs a public consultation. This gives the public an opportunity to provide feedback on proposed changes.
After the consultation closes, all submissions are considered and analysed before decisions are made and updated documents are published.
Each change usually has a transition period of 12 months, but this can vary depending on the nature and scale of the change.
Out-of-cycle changes can still be made when needed, such as to respond to safety issues.
