Granny Flats

A granny flat or dependent person's unit is defined by the Greater Dandenong Planning Scheme as a "movable building on the same lot as an existing dwelling and used to provide accommodation for a person dependent on a resident of the existing dwelling".


Is a permit required?

You need to apply for a building permit for the construction of the dependent person's unit.

A planning permit may not be required, if Council is satisfied that the potential building achieves the following criteria, based on the definition in the Greater Dandenong Planning Scheme.

  • A moveable building
    This must be based on the definition of movable building - "a structure other than a tent, caravan or vehicle, which is designed to be moved from place to place on more than one occasion"

  • Used for the accommodation of a dependent person
    This may be a person who is incapacitated by virtue of medical, economic or social reasons and is therefore dependent on the person in the main dwelling for their accommodation

  • There is only one dependant person's unit on the lot


Helpful information

Check your copy of title for any relevant restrictions or any evident covenants which relate to your property; if so seek legal advice.

Approach Council and seek advice regarding relevant planning controls (i.e. Planning Scheme Overlays) which may have an impact on the development of the dependent person's unit.
