Every property has a zone and unique use and development controls.
Each zone has a use table and use/development standards that must be considered to determine the particular status of an application. Please see Launceston Interim Planning Scheme 2015 Part B Section 8 for more detail.
All use and development of land must be classified within a defined "use class" in the Planning Scheme. Depending on the zone, different uses are either allowable or prohibited. There are four categories that a 'use' can fall into in each zone - No Permit Required, Permitted, Discretionary or Prohibited.
Where development is proposed, an applicable acceptable solution must be met to maintain the status of the use. If the acceptable solution is not met, the development must meet the performance criteria so as not to be prohibited - for example, a Permitted use may become Discretionary. An acceptable solution is measurable and quantitative whereas the performance criteria is more subjective and qualitative.
