From 2021 the Building Code will be updated annually, with only two keys dates for the sector to remember.

Consultation will open on the first Monday in April, while changes were scheduled to be published the first Thursday in November. These dates were chosen to avoid conflicting with school and summer holidays.

Update: Due to disruptions with the COVID-19 response, this date has now been delayed to Monday 29 November.

Changes will come into effect the following November allowing for a minimum transition of 12 months, which allows existing projects to be completed and changes to be incorporated in new projects.

This means that next year:

  • consultation will open Monday, 6 April 2021
  • changes published Monday, 29 November 2021
  • changes will come into effect in November 2022.

This timing will be the same in following years.

Please note - in line with the November 2019 Building Code update, the B1/AS1 requirements for building on liquefaction prone soil will come into force on 28 November 2021.
