Dual occupancy rules in Hobart
Building a dual occupancy in Hobart? City of Hobart applies the Tasmania planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Allowed in the General Residential Zone with a planning permit
Usually yes, with a planning permit. The Tasmanian Planning Scheme allows multiple dwellings in the General Residential Zone, and the acceptable solution is 325 m² of site area per dwelling - so a lot of about 650 m² or more will normally support two dwellings.
Key rules at a glance
| Site area per dwelling | 325 m² per dwelling as the acceptable solution in the General Residential Zone - about 650 m² for two dwellings (indicative - a lesser area can still be approved under the performance criteria). |
| Zones permitted | Multiple dwellings are allowed in the General Residential Zone (325 m² per dwelling) and the Inner Residential Zone (200 m²). The Low Density Residential Zone allows them at 1,500 m² per dwelling where the site is connected to reticulated water, sewer and stormwater, or 2,500 m² otherwise. In the Rural Living Zone residential use is limited to a single dwelling, so multiple dwellings are prohibited there. |
| Approval pathway | Planning permit required. Permitted with no notification if all acceptable solutions are met; discretionary with 14 days notification if any performance criterion is relied on. |
| If your lot is under 325 m² per dwelling | Still possible under the performance criteria - you must show the development will not exceed infrastructure capacity, and either that it is compatible with the density of existing development in the area or that it delivers a significant social or community benefit and sits within 400 m walking distance of a public transport stop or a business, mixed use or inner residential zone. |
| Can it be subdivided or strata titled? | Yes. Subdivision and strata titling are separate applications - a subdivision permit under the planning scheme, then a plan of subdivision for freehold lots or a strata plan under the Strata Titles Act. |
| Typical timeframe | The statutory period is 28 days for a permitted application and 42 days for a discretionary one, and the clock stops while a request for further information is being answered. In practice 3-4 months is common for a discretionary application once notification and any representations are allowed for. |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
How often this applies in Hobart
These are the overlays that can remove the fast-track, measured across every parcel in Hobart from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | 43.26% | 10,295 parcels flagged. 56.74% of the council carries no heritage mapping at all — unassessed, not cleared. |
| Flood | 7.98% | 1,900 parcels flagged. The rest are mapped and sit outside it. |
| Bushfire | 23.51% | 5,596 parcels flagged. The rest are mapped and sit outside it. |
The most common zone in Hobart is General Residential, covering 41.1% of its 23,798 parcels. What you can build is decided by your own lot's zone, not the council's most common one.

Frequently asked questions
Do I need council approval for a dual occupancy in Hobart?
Usually yes. In Tasmania, a dual occupancy generally needs an application, and City of Hobart is the authority that assesses it. See the full state rules for the pathway and what's required.
Which council approves a dual occupancy in Hobart?
City of Hobart is the consent authority for Hobart (Greater Hobart). You can review local planning controls on the council website and lodge through your state planning portal.
What size block do I need for two units in Tasmania?
In the General Residential Zone the acceptable solution is 325 m² of site area per dwelling, so about 650 m² for two. A smaller lot is not automatically ruled out - the performance criteria allow a lesser site area where infrastructure can cope and either the density suits the surrounding area or the project delivers a significant social benefit close to services.
