A granny flat adds valuable living space to your property, whether for family members, rental
income or a home office. Also known as secondary dwellings, ancillary dwellings or backyard
units, these self-contained spaces can be custom designed or built from pre-approved plans.

Requirements vary by state and council. In NSW, many granny flats can be approved via a
Complying Development Certificate (CDC) if they meet certain criteria. Other states may
require a Development Application (DA). Your builder can guide you through the approval
process for your location.
How big can a granny flat be?
Maximum sizes vary by state. In NSW, granny flats can be up to 60/m² of internal floor space.
Victoria allows up to 60/m² as a Dependent Person's Unit. Queensland permits up to 80/m² in
some areas. Check local regulations or ask your builder about limits for your property.
How long does it take to build a granny flat?
Construction typically takes 12-16 weeks once approvals are in place. The approval process
can add 2-8 weeks for CDC or 2-6 months for DA, depending on your council. Prefabricated
or kit homes may have shorter construction times.
Can I rent out my granny flat?
In most states, you can rent out a granny flat to anyone, not just family members. This
can provide valuable rental income. However, rules vary by location, so check with your
local council. Some areas have restrictions on short-term rentals like Airbnb.
