Detached Minor Residential Units

The Government introduced legislation to make it easier for people to build Minor Residential Units also known as granny flats. Changes occurred to both the Building Act and the Resource Management Act, which aim to save homeowners time and money and allow granny flats in more places than before.

How did it work before?

Previously the District Plan regulated the activity status and standards around granny flats, including things like – the amount of land needed, the size of the unit, how many units could be on site, setbacks, having sufficient area for outdoor living, service areas and carparking.

What has changed?

Central Government has introduced a new National Environmental Standard for Detached Minor Residential Units. This piece of legislation overrides the District Plan in some cases and allows detached minor residential units (meaning you don’t need resource consent), if you comply with the standards for – floor area, building coverage, setback from the principal residential unit, and setback from the boundary.

What does it mean for you?

You might be able to build or transport a granny flat onto your property without a resource consent. However, there are some cases - like if you are in a Natural Hazard Area - where you will still need a resource consent.
