NDIS Registration for Builders

Who this guide is for

• Licensed builders receiving referrals for NDIS home modification projects
• Building companies considering registering as an NDIS provider
• Project managers coordinating multi-trade accessibility renovations
• Builders currently subcontracting to registered home modification providers

What NDIS-related building work typically involves

Building work funded through NDIS plans ranges from minor modifications, such as widening a doorway or installing a ramp, through to major projects like extending a home to add an accessible bedroom and bathroom, or constructing a purpose-built dwelling.

Builders are often engaged after an occupational therapist has assessed a participant's needs and prepared a home modification recommendation, which the builder then quotes and delivers, sometimes coordinating plumbers, electricians and other trades.

The scale of the project — from a simple handrail installation to a full accessible bathroom rebuild — significantly affects both the funding pathway and the practical registration considerations that follow.

Do builders need to register with the NDIS Commission?

There is no automatic requirement for every builder doing NDIS work to register. Many builders operate as subcontractors under a registered home modification provider, who holds overall responsibility for the participant relationship and registration.

Where a builder contracts directly with participants, self-managed and plan-managed participants can generally choose to use an unregistered builder for their modification work.

NDIA-managed participants generally need to use a registered provider where the relevant support category requires registration — this becomes more relevant for larger, higher-cost or more complex home modification projects.

Building licensing sits alongside, not instead of, NDIS registration

Comparing the different requirements for builders

Indicative registration group considerations

Home modification-related building work is often indicatively associated with a home modifications registration group, while larger specialist builds may touch on other categories such as specialist disability accommodation-related building work — this is general and indicative only.

The complexity and cost of typical projects a builder undertakes can influence which module of the Practice Standards applies, since higher-risk or higher-cost work may attract closer scrutiny of governance, risk management and quality assurance systems.

Because registration groups and their boundaries are set and interpreted by the NDIS Commission, your Initial Scope of Audit remains the authoritative reference for your specific application.

Steps to prepare a builder's NDIS registration application

A general pathway building businesses often follow.

1. 01

   Review your current licensing and insurance

   Confirm your builder's licence, home warranty insurance and public liability cover are current and appropriate for the scale of work you intend to do.

2. 02

   Map your typical project types to likely registration groups

   Identify whether your work is mostly minor modifications, larger renovations, or new accessible builds.

3. 03

   Complete a self-assessment against relevant Practice Standards

   Work through the Core Module and any applicable Supplementary Modules for your registration group(s).

4. 04

   Develop governance and safeguarding policies

   Prepare documented policies for incident management, complaints, subcontractor management and work health and safety.

5. 05

   Organise worker screening for relevant staff

   Arrange NDIS worker screening clearances for staff and subcontractors who will have contact with participants, where required.

6. 06

   Lodge your application and engage an approved auditor

   Submit your application to the NDIS Commission and, once your scope of audit is issued, engage an independent approved quality auditor.

Documents worth preparing early

• Current builder's licence and any specialist accreditation
• Public liability insurance and home warranty insurance certificates
• Work health and safety management plan and site risk assessment templates
• Subcontractor management and vetting procedures
• Incident and complaints handling procedures tailored to participant projects
• Portfolio of past accessible building or home modification projects, where available

Audit pathway considerations

The audit pathway for a building business — commonly discussed as verification or certification — depends on the registration groups sought and is determined by the NDIS Commission through the Initial Scope of Audit, not by this guide.

Auditors assessing building providers often look closely at how projects are scoped and quoted, how variations and delays are communicated to participants, and how subcontractors are managed and supervised on site.

Because building projects can significantly disrupt a participant's home and daily routine, governance around communication, timelines and dispute handling tends to receive particular attention.

Common mistakes building businesses make

Treating NDIS registration as purely a paperwork exercise separate from actual site practice, rather than something that should reflect how projects are genuinely run day to day.

Failing to clarify with an occupational therapist or support coordinator early in a project which funding pathway applies, which can cause delays or disputes about registration requirements partway through a build.

Overlooking subcontractor screening and management processes, which are increasingly a focus area for auditors given how much building work relies on subcontracted trades.

Frequently asked questions

Do I need to be a registered NDIS provider to build a ramp for a participant?

Not necessarily. For simpler, lower-cost modifications, self-managed and plan-managed participants can often engage an unregistered but appropriately licensed builder. NDIA-managed participants may need a registered provider depending on the support category.

Is a builder's licence the same as NDIS registration?

No. A builder's licence is issued by your state or territory building regulator and is required for licensed building work. NDIS Commission registration is a separate assessment of your suitability to deliver supports to NDIS participants.

What size project usually needs a registered builder?

There's no fixed threshold in general guidance — it depends on how the participant's plan is managed and the specific support category. Larger, higher-cost or more complex modifications are more likely to involve registration considerations.

Do my subcontractors need NDIS worker screening checks?

Subcontractors who have more than incidental contact with participants may need an NDIS worker screening check depending on the registration group and current Commission requirements. Confirm with the Commission and your state screening unit.

Which registration group covers building work?

Home modification-related building work is often indicatively linked to a home modifications registration group, though this varies. Your Initial Scope of Audit from the NDIS Commission will confirm what applies to your specific application.

Can we register just for smaller home modification jobs and not larger builds?

Registration groups are generally selected based on the actual supports you intend to deliver, so it is possible to register only for the scope relevant to your business, subject to the Commission's assessment.
