Why a granny flat here
Why Tarneit Homeowners Add A Granny Flat
Artist's impression -
A Suburb Still Filling In
Tarneit's population is forecast to pass 63,000 by 2031, so demand for extra living space and rental housing keeps climbing.
-
Rental Demand On Your Doorstep
29.5% of Tarneit homes are rented (ABS, 2021 Census). A two-bedroom granny flat in Melbourne is estimated at about $550* a week ($28,600* a year). Xircon's own internal estimate, not a guarantee, and not financial advice.

Big Houses, Bigger Households
97% of homes are separate houses and 72% have four or more bedrooms. On a lot of 300 m² or more, a granny flat of up to 80 m² usually needs no planning permit.
Council and estate rules · City of Wyndham
Granny Flat Rules In Tarneit
Building in Tarneit means working within two separate rule books at once, the state’s small second dwelling rules, and whatever your own title or estate adds on top. We’ve broken both down below
- Planning permit
- A granny flat of up to 80 m² typically skips the planning permit stage, provided your lot is 300 m² or bigger and carries no overlay.
- Lots under 300 m²
- Under 300 m², the City of Wyndham requires a planning permit before you build.
- Building permit
- Required on every job, no exceptions — we handle the application and build the cost into your fixed price.
- Estate covenants
- Many of Tarneit's newer estates carry a single-dwelling covenant on the title for a set number of years after settlement. We check yours before you commit.
- Overlays and easements
- Drainage and waterway reserves near Tarneit's creeks can carry a flood or drainage overlay that limits where the flat sits. Check your lot on VicPlan, or we check it for you.
- Growth-area levy
- Tarneit sits within precinct structure plans with a Development Contributions Plan, updated in 2017. A levy can still apply to some lots, on top of your building permit fee. We confirm whether yours is affected.
- Other rules
- A second car space isn’t required, mains gas isn’t an option, and the flat needs its own access path from the street. Subdividing it off and selling it separately is never allowed.

Granny Flats In Tarneit: Your Questions
What Tarneit homeowners ask us most. Still unsure? Ask a Sales Consultant.
Updated 7 October 2026
Does Tarneit's Growth-Area Status Add Extra Council Costs To A Granny Flat?
Yes, in some cases. Tarneit sits within the Tarneit West and Tarneit North precinct structure plans, under a Development Contributions Plan gazetted in 2008 and updated by Amendment GC75 in 2017. This can add a Community Infrastructure Levy on top of your building permit fees, depending on your lot. Xircon checks whether a levy still applies to your block at the free site inspection.
How Big Are Tarneit Households, And How Does That Shape Granny Flat Demand?
Tarneit's average household holds 3.4 people, and 64.7% of homes have four or more bedrooms (2021 Census) — among the highest shares in Melbourne's west. Many Tarneit families look at a granny flat to give a parent, adult child or visiting relative their own space, without extending or moving house.
What's The Median Household Income And Rent In Tarneit?
$2,103* a week is Tarneit's median household income, and $380* a week is the median rent (2021 Census). A self-contained granny flat can add on top of that: a two-bedroom design is estimated at about $550* a week in rental income across Melbourne — an estimate, not a guarantee, and not financial advice.
Do New Tarneit Estates Like Riverdale Village Or Ecoville Restrict A Second Dwelling?
Yes, some do. Several of Tarneit's newer estates — including Riverdale Village, Ecoville, Creekstone and Westbrook — carry a single-dwelling covenant on the title for a set period after settlement, which can block a granny flat even where no planning permit is required. Xircon checks your specific title and covenant before recommending a design.
Can I Still Rent Out A Granny Flat If My Tarneit Estate Has A Covenant?
Not necessarily. Since December 2023, Victoria allows a granny flat to be rented to anyone, not just family — but a single-dwelling covenant on your Tarneit estate's title can still block a second dwelling altogether, regardless of the state rule. Xircon confirms your covenant position before you commit to building.
How Long Does It Take To Build A Granny Flat Once My Tarneit Permit Is Approved?
10–12 weeks on site, from slab to handover, once your building permit is issued. This covers on-site construction only and excludes permit processing time, weather and site conditions.
Do I Need A Planning Permit For A Granny Flat In Tarneit?
No, not usually. On a lot of 300 m² or more with no overlay or special control, a granny flat of up to 80 m² in Tarneit doesn't need a planning permit from the City of Wyndham. A building permit is still always required, and Xircon arranges it as part of your fixed price.
