The SDA Design Standard sets the design and construction requirements newly built SDA homes must meet to be enrolled with the NDIS. It defines four design categories, and compliance is confirmed by an Accredited SDA Assessor at both the design and as-built stages.
The Specialist Disability Accommodation (SDA) Design Standard outlines the design and construction requirements for newly built SDA homes seeking enrolment under the NDIS. Introduced in October 2019, the standard ensures that SDA properties are purposefully designed to meet the specific support needs of NDIS participants. It provides detailed standards that address a wide range of disability and support requirements, with a strong focus on promoting independence, safety and comfort.
The SDA Design Standard is structured around the four categories of SDA design: Improved Liveability, Fully Accessible, High Physical Support and Robust.
Some of the IL requirements outlined in the SDA Design Standard may include:
Fully Accessible (FA) SDA is designed to promote safety and independence for individuals with high physical impairment. This type of housing may be suitable if you use a wheelchair or other mobility aids to get around in daily life. The FA design requirements set out in the SDA Design Standard ensure the home is highly accessible, allowing you to move through spaces with ease.
Some of these requirements are:
High Physical Support (HPS) is the most comprehensive SDA design category, built for participants with higher support needs – most compatible if you often require additional support and specialised equipment for day-to-day activities. Some of the HPS design requirements stated within the SDA Design Standard may include:
Under the SDA Design Standard, the Robust design category addresses the needs of participants who may present with complex behaviours or psychosocial disability, such as Autism or mental health conditions – ensuring homes support participant safety and comfort as well as the long-term durability of the property.
In accordance with the SDA Design Standard, Robust homes incorporate specific features and materials that prevent injury, neighbourhood disturbances and the need for frequent maintenance.
This includes:
To enrol a newly built home as an SDA dwelling under the NDIS, it must first be certified by an Accredited SDA Assessor – someone who’s authorised to confirm that the dwelling meets the SDA Design Standard.
There are two stages of certification, both of which are mandatory:
Conducted during the design phase. The purpose of this certification is to make sure the proposed plans align with the SDA Design Standard before construction begins.
This certificate confirms that the dwelling matches the approved design and complies with all relevant SDA requirements after the dwelling is physically built.
Throughout both stages, the Assessor reviews key documentation to ensure the SDA dwelling meets the NDIS design standards. This may include:
Once the assessor confirms the home meets the SDA Design Compliance requirements, they issue the SDA As-Built Certificates, along with the SDA Assessment Summary Form and SDA Assessment Checklist. The SDA Provider then submits these documents to the NDIS to finalise the dwelling’s registration and enrolment.
The SDA Design Standard is built to support your independence by shaping homes that respond to your individual needs. It does this by integrating support features directly into the layout and functionality of the home, making daily living safer, more comfortable and more accessible.
Beyond accessibility, the standard also encourages connection with the community . Its guidelines help create environments where you can live, participate and thrive.
The SDA Design Standard enhances the quality of housing by guiding better outcomes for NDIS participants and supporting stronger, more consistent practices within the industry.
The SDA Design Standard recognises that people have diverse needs and preferences. It outlines several SDA design categories, each tailored to different physical and support needs – giving you greater choice in your living environment and helping ensure the home you choose genuinely supports your independence and the way you want to live.
The SDA Design Standard has played a significant role in improving the quality of disability housing across Australia. By setting clear and consistent guidelines, it helps ensure SDA homes are built to a reliable standard of accessibility, safety and compliance – creating greater confidence for participants, providers and support teams alike.
Choosing a home built in line with the SDA Design Standard isn’t just about meeting the technical requirements. It’s also about finding a place that supports your independence, safety and long-term comfort. At Enliven, we design and deliver homes that not only comply with the SDA Design Requirements but go beyond them to create environments where people feel genuinely at home.
At Enliven, our service goes beyond simply providing a compliant SDA home. As part of our Friendly Landlord Model, we stay connected with you and your support network to ensure your home continues to meet your needs, not just on day one, but as your lifestyle evolves – with the added reassurance of a landlord who understands what high-quality, tenant-focused SDA living should feel like.
The SDA Design Standard sets out Assistive Technology (AT) requirements for High Physical Support (HPS) and Fully Accessible (FA) dwellings. At Enliven Housing, we go a step further – alongside HPS and FA dwellings, our Improved Liveability (IL) homes are also built with integrated AT provisions, so your home supports your needs regardless of the SDA category you’re funded for.

Our team is guided by a genuine commitment to helping you live comfortably, safely and with confidence in your home."
