Dual occupancy rules in the NT
In the Northern Territory two or more dwellings on one site are a dwelling-group, if they sit side by side, or a dwelling-multiple, if one sits over another, and whether you can build them depends on the zone. Zone LR allows only one dwelling-single per lot plus a dwelling-independent, so a dual occupancy is not available there. Zone LMR allows one dwelling per 150m2 for one bedroom dwellings and one per 300m2 for larger dwellings, and lists a dwelling-group of fewer than five dwellings as Permitted. Zones MR and HR use density tables based on storeys and bedrooms. Clause 5.4.1 of the Scheme sets the maximum number of dwellings and the consent authority can vary it only where satisfied the proposal is consistent with the clause and zone purpose.

Dwelling-group and dwelling-multiple
The NT Planning Scheme 2020 does not use the term dual occupancy. Schedule 2 defines a dwelling-group as one of a group of two or more dwellings on the same site where no dwelling is placed wholly or partly vertically above another, including a dwelling on a unit title with common property. A dwelling-multiple is a dwelling that is wholly or partly over or under another dwelling on the site, including dwellings above the ground floor in a mixed use development.
Two houses or villas side by side on one lot are therefore a dwelling-group. A pair of flats one above the other is a dwelling-multiple. The distinction matters because the zone assessment tables treat them differently, and a dwelling-group is listed separately from a dwelling-single and a dwelling-independent.
dwelling-group means a dwelling that is one of a group of two or more dwellings on the same site such that no dwelling is placed wholly or partly vertically above another, except where special conditions of landscape or topography dictate otherwise, and includes a dwelling on a unit title with common property; dwelling-multiple means a dwelling or serviced apartment that is wholly or partially vertically over or under another dwelling on a site or any dwellings above the ground floor in a mixed use development, and includes a dwelling on a unit title with common property;

The zone decides whether a second dwelling is possible
Each zone in Part 4 has an assessment table that gives every defined use an assessment category: Permitted, Merit Assessable, Impact Assessable or Prohibited. In Zone LR, Low Density Residential, the table lists Dwelling-Single and Dwelling-Independent as Permitted, and then says all other uses defined in Schedule 2 are Prohibited. A dwelling-group is not in the Zone LR table, so it is prohibited there and the consent authority must not grant consent.
Zone LMR, Low-Medium Density Residential, is where dual occupancies start. Its table lists a dwelling-group of less than 5 dwellings as Permitted, a dwelling-group of 5 or more as Merit Assessable and a dwelling-multiple as Merit Assessable. In Zone MR, Medium Density Residential, a dwelling-multiple is Merit Assessable and a dwelling-group is Impact Assessable, reflecting that the zone is intended for flats rather than villas.

How many dwellings the site can carry
Clause 5.4.1 Residential Density sets the maximum number of dwellings on a site by reference to Tables A to D. Table A gives Zone LR one dwelling-single per lot with an optional dwelling-independent, and gives Zone LMR a choice: the same single house allowance, or one dwelling per 150m2 for a one bedroom dwelling and one per 300m2 for a dwelling with two or more bedrooms as part of a dwelling-group or dwelling-multiple. Zone CL and Zone T allow one dwelling per 300m2 in a dwelling-group, and Zones H and A allow two dwellings per lot in a dwelling-group.
Zone MR outside Alice Springs uses Table B, which sets site area per dwelling by storeys and bedrooms: for single storey, 155m2 for one or two bedrooms, 180m2 for three and 215m2 for four, and for two storeys 125m2, 170m2 and 210m2. In Alice Springs Table C sets 400m2 per dwelling at one storey and 200m2 at two storeys for Zones MR and TC. Zone HR has its own Table D.
The consent authority may consent to more dwellings than the table allows only if satisfied the proposal is consistent with the purpose of the clause and the zone purpose and outcomes and appropriate to the site. An area that can readily be converted to a bedroom is counted as a bedroom for the purposes of the tables.
1. The consent authority may consent to a development that is not in accordance with sub-clause 2 only if it is satisfied it is consistent with the purpose of this clause and the zone purpose and outcomes, and it is appropriate to the site having regard to such matters as its location, scale and impact on adjoining and nearby property. 2. The maximum number of dwellings that may be constructed on a site is to be determined in accordance with Table A, B, C or D (as the case requires) to this clause.

The other requirements a dwelling-group must meet
Density is only the first test. The Zone LMR table also points a dwelling-group to the setbacks in clause 5.4.3, the private open space in clause 5.4.6 and the residential building design and articulation clauses. Each dwelling-group unit needs 45m2 of open space open to the sky with no dimension under 1.5m plus 24m2 of dimensioned covered or open space with no dimension under 4m, and ground level open space should be screen fenced to at least 1.8m.
Buildings on the same site are set back from each other as if there were a lot boundary between them, using Table A to clause 5.4.3 for one and two storey buildings. Later extensions and ancillary structures to an existing dwelling-group are Permitted without consent if they meet clause 5.4.4.
3. Where the private open space for a dwelling-group is at ground level, it should be: (a) screen fenced to a height of at least 1.8m providing a visual barrier to adjoining residences and public areas; or (b) fenced to a height of at least 1.8m and planted with dense vegetation which will provide a visual barrier at maturity. Dwelling-group Dwelling-single on a lot less than 450m2 Dwelling-independent in addition to the private open space requirement for the dwelling - single A. 45m2, open vertically to the sky, with no dimension less than 1.5m; and B. 24m2, all or partly covered, with no dimension less than 4m.

2. Where more than one building comprising one or two storey residential buildings is located on a site the distance between the buildings is to be calculated in accordance with Table A to Clause 5.4.3 as if there was a lot boundary between the buildings. 1. An extension to an existing dwelling-group or dwelling-multiple, or addition of an ancillary structure, is Permitted without consent if it complies with sub-clause 2.

Permitted or Merit Assessable: the consent question
A dwelling-group of fewer than five dwellings in Zone LMR is Permitted, which under Part 1 clause 1.8 means no development permit is needed if it meets every relevant Part 5 requirement and no overlay requires consent. If it exceeds the density table, misses a setback or sits in a flooding or storm surge overlay, it becomes Merit Assessable and needs consent from the consent authority under the Planning Act 1999.
In a Merit Assessable application the consent authority must consider the Part 5 requirements not met and whether the proposal still meets their purpose, along with the overlays and the guidance in the zone purpose and outcomes. It may vary a requirement only where satisfied the variation is appropriate having regard to that requirement's purpose and administration clauses.
2. In considering an application for consent for a use or development that has become Merit Assessable under Clause 1.8(1)(b)(ii)(2), the consent authority must consider the requirements in Part 5 that are not complied with and whether the proposal meets the purpose of the requirements. 5. The consent authority may consent to a proposed use or development that is not in accordance with a requirement set out in Parts 3, 5 or 6 only if it is satisfied that the variation is appropriate having regard to: (a) the purpose and administration clauses of the requirement; and (b) the considerations listed under Clause 1.10(3) or 1.10(4).

This Part applies in any of the following circumstances: (a) if a provision of a planning scheme allows development only with the consent of the consent authority; (b) if the proposed development is the subdivision or consolidation of land; (c) if an interim development control order allows development only with the consent of a consent authority.

What changes council by council in Northern Territory
The state instruments set the frame. These points are set by each council's own instrument or mapping, so the answer for an address depends on which council it sits in.
- NT councils do not make planning schemes. The zone at a site is set by the NT Planning Scheme 2020 zone maps, and the zone's assessment table decides whether a dwelling-group or dwelling-multiple is Permitted, Merit Assessable, Impact Assessable or Prohibited.
- The density table that applies depends on the zone and on whether the site is in Alice Springs, which has its own Table C for Zones MR and TC.
- Part 3 overlays such as land subject to flooding, storm surge, and land adjacent to a designated road can require consent for an otherwise Permitted dwelling-group.
- Area plans in the Strategic Framework prevail over zone purposes and outcomes and guide Merit and Impact assessment, but they do not change the assessment category.
- Building setback plans in Schedule 9 can replace the standard setbacks for particular land.

For your address
How the $150 report settles this for one site
A Casa preliminary planning report reads the NT Planning Scheme zone and the Part 3 overlays mapped at your parcel, reports the assessment category for a dwelling-group and a dwelling-multiple in that zone's table, and applies the clause 5.4.1 density table for that zone to your site area to show the maximum number of dwellings on the deemed numbers. It sets out whether the proposal is Permitted without consent or needs a development permit, and it does not decide the application.
Common questions
Can I build a dual occupancy in Zone LR?
No. Zone LR allows one dwelling-single per lot with an optional dwelling-independent, and its assessment table makes all other defined uses Prohibited, which the consent authority must not consent to. A granny flat is the only second dwelling available in Zone LR.
What block size do I need for two dwellings in Zone LMR?
Table A to clause 5.4.1 allows one dwelling per 150m2 for a one bedroom dwelling and one per 300m2 for a dwelling with two or more bedrooms as part of a dwelling-group or dwelling-multiple. The site must also fit the setbacks, parking and private open space for each dwelling.
Do I need a development permit for two villas in Zone LMR?
Not if the dwelling-group has fewer than five dwellings, meets every relevant Part 5 requirement and no overlay requires consent, because the Zone LMR table lists it as Permitted. Any departure from a requirement makes it Merit Assessable and consent is required.
Why is a dwelling-group Impact Assessable in Zone MR?
The Zone MR assessment table lists Dwelling-Group as Impact assessable and Dwelling-Multiple as Merit assessable. Under Part 1 clause 1.8 Impact Assessable development requires the consent authority to consider whether it is appropriate for the location and accords with the Strategic Framework.
Can the consent authority approve more dwellings than the density table allows?
Only if satisfied the proposal is consistent with the purpose of clause 5.4.1 and the zone purpose and outcomes, and appropriate to the site having regard to its location, scale and impact on nearby property.
Does a study count as a bedroom for the density tables?
The Editor's Note to clause 5.4.1 says an area that can be readily converted to a bedroom, or that combines sleeping and living areas, is considered a bedroom for the purpose of the clause.
