How much does a granny flat cost in Hobart?
The cheapest way into a granny flat in Hobart is a one-bedroom prefab or modular unit at $80,000–$120,000 delivered, before it is set down and connected. A builder's turnkey studio or one-bedroom flat of 35–45 m² costs $110,000–$160,000, and a two-bedroom of about 60 m² $140,000–$210,000, with $175,000 typical.

Hobart’s Granny Flat Market in 2026
Tasmania now calls a granny flat a secondary residence: self-contained, no more than 60 m² of floor area, ancillary to a single dwelling, and it must share the main house’s access, parking, services and meters. In the General Residential Zone that use needs no planning permit.
The City of Hobart will confirm in writing, free of charge, whether a proposal is exempt; planning applications go through PlanBuild. On the building side a new dwelling is notifiable building work: a building surveyor certifies it and notifies council. The planning and building approval row is $3,000–$12,000.
The two-bedroom price in the Hobart table is $140,000–$210,000 turnkey, against $110,000–$160,000 for one bedroom.

What Affects Granny Flat Costs in Hobart
The 60 m² secondary residence
Tasmania's State Planning Provisions define a secondary residence as self-contained, no bigger than 60 m² in gross floor area and attached in use to a single dwelling. Built right up to that size at $2,300–$3,500 a square metre, a flat comes to $138,000 to $210,000. A unit that misses the definition may be assessed as multiple dwellings instead, which some zones prohibit.
Shared meters and driveway
A Tasmanian secondary residence shares the main house's access and parking, and its water, sewerage, gas, electricity and telecommunications connections and meters. That rules out separate meters, but it also means the services run from the existing house. Our table puts site works and connections at $15,000–$40,000; siting the flat's kitchen and bathroom close to the house's plumbing keeps those runs, and the bill, shorter.
Planning: is it exempt?
In the General Residential Zone, residential use for a single dwelling is listed as No Permit Required, and a lot holding a house plus a secondary residence still counts as a single dwelling. If you believe your plan is exempt, the City of Hobart will confirm it in writing, free, through a Pre-Application Enquiry. Applications are lodged through PlanBuild.
Building surveyor and builder
On the building side, a new dwelling of up to two storeys is notifiable work in Tasmania: a building surveyor issues a Certificate of Likely Compliance, which goes to council before work begins. The builder you sign with should hold a Tasmanian builder's licence. Our table prices planning and building approval together at $3,000–$12,000, and clearing an existing structure, where needed, at $3,000–$15,000.
Deposits on prefab and kit homes
A Tasmanian building contract of $20,000 and up needs to be written, signed by both sides and dated, with a five-business-day cooling-off period. The deposit is capped at 5% from $50,000, which every new build in our table passes. A prefab or kit home is the exception: where work done off-site is more than half the price, the cap rises to 20%, so a delivered unit at $80,000–$120,000 can ask a bigger deposit.
Conversion, garage or two storeys
Turning an existing garage or outbuilding into a flat costs $40,000–$120,000, typically less than even a delivered prefab when the shell is sound. A new flat with an attached single garage, site costs and approvals included, is $170,000–$260,000. A two-storey design is the dearest in the table at $280,000–$425,000.
Built for a cool climate
Greater Hobart falls in the NCC's cool-temperate zone 7, and its coldest month, July, averages 11.8 °C at its warmest and 4.6 °C at its coolest at Ellerslie Road (BOM averages). Insulation, glazing and heating matter more here than in warmer zones, and better windows or a heat pump push a build up its band. Premium finishes on a two-bedroom flat take it to $210,000–$320,000.
