Dual occupancy rules in Launceston
Building a dual occupancy in Launceston? City of Launceston 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 and Inner Residential zones. The Low Density Residential and Rural Living zones apply much larger site areas per dwelling. |
| 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 surrounding density or that it delivers a significant social or community benefit within 400 m walk of services. |
| 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 | About 42 days for a permitted application; commonly 3-4 months for a discretionary application once the notification period 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.
