The NSW Government has made granny flats easier and faster to build. These secondary dwellings also give families the chance to use a Granny Flat as a source of additional income in these challenging economic times.
Development of a granny flat can be considered upfront as part of building a new house or as an addition to an existing house.
A Granny flat is a self-contained extension of the family home that:
- is established in conjunction with a house and is either within the house, or attached to the house, or separate from the house; and
- is on the same lot of land as the principal house and is not on a separate lot, in a strata plan or in a community title scheme.
Granny flats are now permitted in all residential zones across the State, subject to meeting the following requirements:
- There is only one house and one granny flat on the lot
- The combined total floor area of the house and the granny flat complies with the floor space area controls in the local environment plan
- The maximum floor area of the granny flat is no greater than:
- 60 square metre
- The maximum floor area prescribed by the council in the local environmental plan
- The lot is not subdivided
- The granny flat meets planning controls such as building height and setbacks, floor space ratios, and open space in the local environmental plan and/or the complying development provisions in the Affordable Rental Housing SEPP.
- The granny flat meets the requirements of the Building Code of Australia.
There are no requirements under the policy to provide any additional parking for the granny flat.
A granny flat may occur either with DA consent, or as complying development.
