Small second home

Whether you need a planning permit to build a small second home depends on the land’s size, its zone, and any overlays.

You must apply for a permit if either your zone or overlays require you to get one.

A small second home must be:

  • 60 square metres or less in floor area
  • on the same lot as an existing home
  • used as a home
  • have a kitchen, bathroom, and toilet.

When you need a planning permit

Land less than 300 square metres

You must get a planning permit if your land is less than 300 square metres and in a:

  • Mixed Use Zone
  • Residential Growth Zone
  • General Residential Zone
  • Neighbourhood Residential Zone.

A permit is not required in a residential zone if the land is 300sqm or more. However, you might still need a permit depending on your overlays.
