Fill in all fields.
In the first column provide the total numbers of all different dwelling types that are available in the development on a single parcel of land.
Note that 'total' numbers of dwelling types are required, regardless of fact that an SDA participant may or may not occupy that particular dwelling type.
This will generate the total number of 'Residents' in the development based on 1 bedroom per resident.
In the second column, select ‘Yes’ if any SDA 'Participant' is occupying or intending to occupy that particular dwelling type.
Selecting ‘Yes’ would mean that, the particular type of dwelling is an Enrolled dwelling ie will be enrolled with NDIS as an SDA dwelling.

Purpose of the Calculator
This Calculator is to assist with the density requirement calculations based on Vista Access Architect’s interpretation of density restrictions noted in the NDIS (National Disability Insurance Scheme) SDA (Specialist Disability Accommodation) Rules 2020.

Our interpretation
In the context of NDIS SDA Rules 2020: ‘Participants’ are people with SDA in their NDIS plan.

‘Residents’ are total number of people who can reside in a development including within a dwelling enrolled or being enrolled for SDA. For purposes of calculations it is assumed that one bedroom equates to one resident. Therefore, the number of participants with SDA in their plan intended to reside in the dwelling may be lower than the number of residents for which the dwelling is being enrolled.

‘Enrolled dwelling’ is a dwelling that is occupied or intended to be occupied by an SDA ‘participant’.

‘Intentional community’ has a defined and explicit agreement under which residents have agreed to live in accordance with shared common values, including the principle of mutual support; is controlled by the members or residents and is not governed by a single entity such as a support provider; and includes general market housing, and is not solely designed to provide supported accommodation services.

Density restriction is covered in Subdivision C- Clause 31.
(1) The density restriction applies in relation to a parcel of land if: (a) the parcel of land has 2 or more dwellings; and (b) at least one of those dwellings is either a new build; or existing stock.

(2) If the density restriction applies in relation to a parcel of land, the total number of eligible participants that can receive funding for specialist disability accommodation in relation to all dwellings located on the parcel of land must not exceed:

(a) if one of the dwellings on the parcel of land is enrolled to house 3 or more residents—the greater of the following:

(i) 10 eligible participants;

(ii) 10% of the total number of residents capable of residing on the parcel of land, assuming one resident per bedroom; or

(b) if all of the enrolled dwellings on the parcel of land are enrolled to house no more than 2 residents and the dwellings are part of an intentional community—the greater of the following:

(i) 15 eligible participants;

(ii) 25% of the total number of residents capable of residing on the parcel of land, assuming one resident per bedroom; or

(c) if all of the enrolled dwellings on the parcel of land are enrolled to house no more than 2 residents and the dwellings are not part of an intentional community—the greater of the following:

(i) 15 eligible participants;

(ii) 15% of the total number of residents capable of residing on the parcel of land, assuming one resident per bedroom.
