The SDA Design Standard outlines the design and construction requirements for newly built SDA homes seeking enrolment under the NDIS.
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 was published by the NDIS in 2019 and became mandatory for all new SDA from 1 July 2021. It replaced the earlier Livable Housing Design Guidelines that SDA used to rely on. It applies to newly built homes and to existing homes that are being newly enrolled or significantly refurbished as SDA, which is why newer SDA homes are generally built to a higher and more consistent standard than older stock. The Standard is also reviewed over time to keep pace with best practice, and a review is currently underway to shape its next edition, so specific requirements can change between editions.
The SDA Design Standard is structured around the four categories of SDA design: Improved Liveability, Fully Accessible, High Physical Support and Robust, plus the SDA design categories hub.
Improved Liveability (IL) caters to participants with sensory, intellectual or cognitive impairments. It offers design features that can significantly enhance the liveability of those who may need that extra bit of support in their home. Some of these features include contrasting walls and doors, improved wayfinding with limited corridors, task lighting and visual assistance lines. The main outcome of Improved Liveability housing is to assist you to navigate around and promote overall safety and comfort.
The Fully Accessible (FA) design category caters to individuals with high physical impairment. The main focus of this design is to support mobility so you can move around your home with ease. The main features of FA SDA include wider doorways and corridors, flat flooring and open-plan layouts.
The High Physical Support (HPS) design category caters to individuals with high physical impairment and require a lot of support with daily activities. Similar to the FA design category, this category features open-plan layouts, step-free accessways and wide corridors. Additionally, other provisions such as ceiling hosts and even wider door openings are required to enhance accessibility, movement and comfort for you.
The Robust SDA design category caters to individuals with disability such as autism, mental health conditions and other psycho-social disorders. Homes under the Robust category are built with durable and strong materials that prevent injury, neighbourhood disturbances and the need for frequent maintenance.
Improved Liveability, Fully Accessible, High Physical Support and Robust. Each has its own set of design features under the SDA Design Standard.
A home cannot simply call itself SDA. To be enrolled under a design category, it must be assessed and certified by an accredited, independent SDA Assessor against the requirements of the SDA Design Standard, first at the design stage and again once the home is built. This independent check, sometimes called an SDA assessment, is what gives you confidence that a home genuinely meets the category it is enrolled as, rather than just claiming to.
There are two stages of certification, both which are mandatory:
The provisional design certification is 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.

These two are easy to mix up. The SDA Design Standard sets out how an SDA home must be designed and built. The NDIS Practice Standards are a separate set of quality and safety standards that registered providers must meet in how they deliver their services.
A good SDA provider meets both: the homes meet the Design Standard, and the organisation meets the Practice Standards.
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.
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. This means you benefit from an SDA home designed to standard, 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. This way, your home is designed to support your needs regardless of the SDA category you’re funded for.
At Enliven, meeting the SDA Design Standard is only the start. While the standard lays the foundation for accessibility and safety, we go further by prioritising location, amenities and access to transport. Our Design Philosophy blends compliance with thoughtful, tenant-centred design to create SDA homes that genuinely enhance your independence and quality of life.
We build beyond the minimum of the SDA Design Standard, not just to it, so every part of the home is as functional as possible. Purpose-built for independence, not just compliance.
"At Enliven, our dedicated Assistive Technology Team works closely with you, your Occupational Therapist (OT) and Support Coordinator to develop a tailored quote and service agreement for submission to the NDIA. Our team is guided by a genuine commitment to helping you live comfortably, safely and with confidence in your home.”
