​Who is SDA For?

SDA is designed for NDIS participants who:

• Have extreme functional impairment, meaning significant difficulty completing daily activities even with assistive technology, or

• Have very high support needs, requiring frequent or ongoing person‑to‑person assistance where standard housing is not suitable

The NDIA assesses whether SDA is a reasonable and necessary support and whether it will improve long‑term safety, independence and outcomes for the participant.

​

SDA Design Categories (Types of SDA Homes)

Under the NDIS SDA Design Standard, SDA homes are classified into four design categories, each suited to different support needs.

Improved Liveability

Designed for participants with sensory, intellectual or cognitive impairments.
These homes include features such as improved lighting, visual contrast and better wayfinding to support safety and independence.

Fully Accessible

Designed for people with significant physical disabilities.
These homes are wheelchair‑accessible throughout and include step‑free access, wider doorways, and accessible kitchens and bathrooms.

High Physical Support

Designed for participants with very high physical support needs.
These homes include advanced assistive technology such as ceiling hoists, automated doors, structural reinforcement and backup power systems.

Robust

Designed for participants with complex behaviours or safety risks.
Robust homes use durable, impact‑resistant materials and layouts that improve safety while reducing ongoing maintenance.

​

Types of SDA Properties

SDA housing can be delivered in different formats depending on participant needs and location, including:

• Apartments

• Villas, duplexes and townhouses

• Stand‑alone houses

• Small group homes (shared living)

All SDA properties must meet the SDA Design Standard and be enrolled with the NDIA before SDA payments can be claimed.

​

How SDA Funding Works

• SDA funding is paid directly to the SDA housing provider or property owner

• Payments depend on the design category, building type and location

• Participants contribute a reasonable rent amount, similar to standard housing

• SDA payments continue while the participant occupies the property and remains eligible

​

SDA Home Loan Process

(This section explains how SDA finance works from a lending perspective. It is general information and not NDIA advice.)

SDA properties are assessed differently from standard residential homes. As an SDA‑experienced mortgage broker, I guide clients through this specialised process to reduce risk and improve approval outcomes.

 

Step 1: SDA Eligibility & Strategy Review

Before applying for finance, we confirm:

• SDA funding approval (or progress towards approval)

• Correct SDA design category

• Suitable property type and location

• Appropriate ownership structure (individual, trust, company or SMSF)

This step ensures the loan structure aligns with lender expectations from the start.

 

Step 2: Pre‑Approval with SDA‑Friendly Lenders

Not all banks understand SDA.

I work with lenders who:

• Accept SDA rental income, not just market rent

• Understand NDIA payment structures

• Are comfortable with purpose‑built SDA properties

Standard lending checks still apply (income, expenses, credit history), but SDA income is assessed differently.

 

Step 3: Property Valuation & SDA Compliance

Lenders usually require:

• An SDA‑aware property valuation

• Confirmation the property meets SDA Design Standards

• Evidence the dwelling can be enrolled (or is already enrolled) with the NDIA

Using valuers and lenders familiar with SDA significantly reduces delays.

 

Step 4: Loan Approval & Settlement

Once approved:

• Loans may be Principal & Interest or Interest‑Only

• Residential‑style loan terms are often used

• Construction loans are available for new SDA builds

After settlement, SDA payments can commence once the property is enrolled and occupied.

 

Why Use an SDA‑Experienced Mortgage Broker?

SDA lending is highly specialised. An experienced broker helps you:

• Avoid lenders that decline SDA deals

• Structure loans correctly from day one

• Reduce valuation and approval risks

• Coordinate with builders, SDA providers and support coordinators

This expertise can be the difference between approval and decline.

 

Speak to an SDA Finance Specialist

If you are:

• An NDIS participant or family exploring SDA housing

• An investor building or purchasing SDA property

• A support coordinator seeking reliable finance guidance

I can guide you through the entire SDA finance journey, from strategy to settlement.
