The owner and the provider
Under the SDA Rules 2020, it is an SDA provider who may apply to enrol a dwelling. The two roles can sit with different people. If the provider does not own the dwelling, the application must name the owner, and the provider must certify that the owner has agreed in writing that the provider can enrol it and that the owner will not enrol it separately.
The provider has to be registered. The NDIA says providers need to be registered with the NDIS Quality and Safeguards Commission to offer SDA, and that the SDA rules require every home to be enrolled by the NDIA.
Victoria adds a definition of its own. Consumer Affairs Victoria explains that an SDA provider there is the owner or leaseholder of an SDA dwelling that is let, or proposed to be let, to an SDA resident under an SDA residency agreement or a residential rental agreement.
