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
Build method
Prefab or modular units (from ~$80,000 delivered) are cheapest; standard site-built homes are mainstream; custom and two-storey designs cost the most.
Size & bedrooms
A 1-bed (35–45m²) runs $110,000–$160,000 turnkey; a 2-bed (~60m²) $140,000–$210,000.
Site works & access
Slope, rock, poor access and craneage add $15,000–$40,000. Flat, clear, easy-access blocks are far cheaper to build on.
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 Tasmania a 'secondary residence' — a self-contained residence of not more than 60m² gross floor area on the same lot as a single dwelling, sharing its access and service connections — is allowed on many lots, needing planning and building approval through your 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.
