From 31 August 2020, some building projects no longer need a building consent. This is great news – there will be lower costs and it will be faster and easier to turn those dreams into reality
Building consents will no longer be required for a number of projects, including certain sized carports, sleepouts, sheds, ground-floor awnings, verandas and porches. There are also many other projects that don’t need a building consent which you can learn about too.
Even though you don’t need a building consent, there are still rules to follow. On this page you can link through to helpful information to help you understand what types of building projects will no longer need a building consent and other useful information to help you turn your dreams into reality.
