Sunshine Coast’s Granny Flat Market in 2026
In Sunshine Coast, the granny flat is one of the most-requested home additions going. High property prices, multi-generational living, and strong rental demand make a secondary dwelling one of the higher-return additions a Sunshine Coast homeowner can make — a 2-bedroom granny flat rents well and can lift property value by 10–30%. Queensland’s relaxed secondary-dwelling rules and the Coast’s strong rental market make a backyard build an attractive income option.
The biggest swing in price is build method. Prefab and modular units (from about $76,000 supplied) are the budget end; standard site-built 1- and 2-bedroom homes ($105,000–$200,000 turnkey) are the mainstream; and custom or two-storey builds run $200,000–$404,000+. Site works and service connections ($14,000–$38,000) and approvals are the costs homeowners most often underestimate.
On the rules: In Queensland a secondary dwelling (granny flat) can be rented to anyone since 2022, with a 60m² baseline in most council schemes, though approval paths and size rules vary by council. Build method, finishes and site access set the price, plus services and approval.

What You’ll Actually Pay — Common Sunshine Coast Granny Flat Builds
These are real-world all-in prices for common Sunshine Coast granny flat builds in 2026 — covering build, standard site works, services and approvals where they apply.
1-bedroom granny flat — 40m², turnkey
$105,000–$143,000 total
The most popular build for independent living or a single tenant on a standard Sunshine Coast block. A detached single-storey home with bedroom, bathroom, kitchenette and open living, standard finishes, slab and service connections. Around 12–14 weeks once approved.
2-bedroom granny flat — 60m², turnkey
$143,000–$200,000 total
The strongest rental option — two bedrooms, a full bathroom and a real kitchen. Standard-to-mid finishes with slab, services and approval rolled in. Budget 14–16 weeks of build time once approved; it’s the bread-and-butter Sunshine Coast investment build.
Prefab / modular 2-bed — installed
$90,000–$152,000 total
Built off-site and lifted in, then hooked up to services on a prepared slab. Quicker and cheaper than a site build with far less mess — just remember slab, site works and connections are usually extra on top of the unit price.
Garage / outbuilding conversion to studio
$43,000–$90,000 total
Converting an existing garage or outbuilding is the cheapest route to a secondary dwelling, but plumbing, a bathroom and kitchenette, insulation, glazing and compliance upgrades drive the price. Best value where the existing slab and walls are sound.
Custom architect 2-bed / two-storey
$247,000–$404,000 total
A premium, fully designed secondary dwelling — high-end finishes, a larger footprint, or a two-storey design on a tight block. Needs design and engineering, and is common across the coastal suburbs where land value justifies the spend.
What Affects Granny Flat Costs in Sunshine Coast
Build method
Prefab/kit units (from ~$76,000 supplied) are cheapest; standard site-built homes are mainstream; custom and two-storey designs cost the most.
Size & bedrooms
Expect $105,000–$152,000 for a turnkey 1-bed (35–45m²) and $133,000–$200,000 for a 2-bed (~60m²) — 60m² being the usual size cap.
Site works & access
A flat, clear, easy-access block is cheapest; slope, rock, tight access and craneage can add $14,000–$38,000 in site works.
Service connections
Water, sewer, power and stormwater connections add cost — keeping wet areas near the main house’s services keeps plumbing runs short.
Approvals
In Queensland a secondary dwelling (granny flat) can be rented to anyone since 2022, with a 60m² baseline in most council schemes, though approval paths and size rules vary by council.
Finishes & inclusions
Standard finishes keep costs down; stone benchtops, premium flooring, decks and air-conditioning push a build toward the top of the range.
