For NDIS participants and families navigating home modifications, the journey often starts with understanding how a person moves through their home and completes daily activities. Through Pursue Ability, expert NDIS occupational therapy for home modifications can include a thorough assessment of those needs and a detailed report to help inform funding decisions.

The assessment can explain the proposed work to a builder and help identify essential information needed for a comprehensive quote. Relevant hospital or clinical discharge advice can also help inform the assessment. Funding decisions ultimately depend on how the recommendations relate to the person’s disability, daily living needs and NDIS plan.

This article explains how occupational therapy assessments, modification categories and builder quotes fit into the process. It also outlines Support at Home options, so you can identify which pathway to discuss with your support coordinator, plan manager or the relevant decision-maker.

How does occupational therapy home modification work?

NDIS occupational therapy for home modifications begins with understanding how disability affects daily activities and movement around the home. An occupational therapist considers the person’s abilities and home layout, then recommends changes that may support independence and everyday tasks.

Minor and complex modification categories

NDIS home modifications are described as minor or complex. Minor modifications cost less than A$20,000 and generally affect one or two areas of a home. The NDIS classifies minor work as Category A or Category B, depending on cost and other factors.

Complex modifications cost more than A$20,000 or involve internal structural work. The category helps describe the scale of proposed work. The assessment should also explain how the change relates to the participant’s needs and daily activities.

Complex modifications for significant disabilities

Participants with significant disabilities may need changes to how they enter, move through or use their home. Complex work can include widened doorways, accessible bathrooms, ramps or lifts, and redesigned kitchens. These projects may involve structural adjustments, not just a small alteration in one room.

The occupational therapist considers the person’s abilities, home layout and daily activities. Recommendations can describe the work needed and its purpose. Builders and engineers may contribute to complex proposals, helping address practical and structural requirements.

Professionals and qualifications

An occupational therapist assesses the participant and recommends suitable modifications. Builders carry out the work, while engineers may contribute to complex structural proposals. The therapist can work with these professionals and the participant’s support team to connect the design with everyday needs.

For Category B minor home modifications and complex home modifications, the NDIS guidance sets expectations for assessors to demonstrate specified qualifications and training. One assessor pathway is NDIS-authorised complex home modification assessment training completed before 30 June 2016. The assessor’s relevant training matters when preparing recommendations for a funding request.

Checking completed modifications

An occupational therapist may check a completed modification to assess whether it is safe and functional and meets the participant’s goals. Confirm with the occupational therapist or support coordinator whether this check is required or included. For example, a doorway change could be reviewed against the access need described in the assessment.

This check can connect the recommendation with the completed work. If a modification is intended to assist with a daily activity, a review may consider whether the person can use it for that purpose. NDIS occupational therapy for home modifications can link the proposed change, the participant’s goals and the finished work.

Occupational therapy home assessments

An occupational therapist assesses the person’s abilities, daily activities and home layout. Their findings can guide recommendations for changes that address disability-related barriers.

Home assessment requirements

An occupational therapist’s assessment may be required before home modification funding is approved under the NDIS or Support at Home. Requirements depend on the relevant program and the proposed modification, so check with the NDIS or Support at Home about what is needed. An assessment can give decision-makers information about the person’s needs and home environment. It considers the specific modification requested, rather than treating every home or proposed change alike.

There is no single cost for every home assessment and report. The amount payable depends on the occupational therapy service arrangement and the participant’s funding. For a specific assessment, discuss the expected charge and relevant plan budget with your support coordinator or plan manager.

Assessment recommendations and reports

The occupational therapist considers physical abilities, mobility challenges and the home layout. They may also assess daily activities, such as moving between rooms or using a particular space. These observations help shape recommendations around what the person needs to do at home.

A home modifications report can explain how each recommendation relates to the person’s disability and goals. It may include diagrams and details of the proposed work. This information can support a funding request and help a builder understand the intended scope.

Home access assessment

An access assessment looks at how the person enters and moves around their home. The occupational therapist considers routes through the property, mobility needs and barriers in the layout. This can clarify which areas affect access and what changes may address the difficulty.

The therapist may trial assistive technology to assess whether an option is suitable and safe. For example, they can consider how it fits the person’s abilities and use of the space. The report can then explain the recommendation in relation to the access need.

Assessment during a home visit

During a home visit, the occupational therapist observes relevant daily activities and movement around the home. They assess the person’s abilities alongside the layout, focusing on areas related to the proposed modification. For example, they may look at the route the person takes to reach a room.

The therapist can discuss the person’s goals and gather information for functional recommendations. If assistive technology may help, they can trial options for suitability and safety. These observations inform the report and recommendations, supporting discussion about the participant’s NDIS plan.

NDIS guidelines for home modification funding

Funding decisions consider how a proposed change relates to your disability, needs and NDIS plan. The assessment should explain how the modification supports daily activities, access or independence.

Safety, access and independence

A modification should address a specific barrier in the home. For example, an accessible bathroom may support safer use of that room, while a ramp may improve entry. The occupational therapist’s report connects the recommended work with your abilities and daily activities.

NDIS home modifications should support independence and provide an appropriate, cost-effective response to your needs. The recommendation must relate directly to your disability and align with your plan goals. These points help explain why the proposed change is needed, rather than simply preferred.

Access, mobility and environmental control

Access changes can address movement into or through the home. Mobility-related work may involve widened doorways, ramps or lifts. Bathroom changes can support access to washing and personal care. The right recommendation depends on the person’s movement, abilities and home layout.

Environmental control changes may help a participant operate parts of their home. An occupational therapist can assess needs and recommend assistive technology or other suitable options. The report should link each recommendation to a practical task, such as using a control independently.

NDIS eligibility for home modifications

The NDIS provides support for people with permanent and significant disability. Funding for a particular home modification depends on the participant’s specific needs, plan and evidence. Recommendations should relate to the disability, support daily living, represent good value and be considered reasonable and necessary.

If you rent or live in social housing, involve the landlord or housing provider early to discuss the proposed work and practical arrangements. Obtain NDIS approval before modification work begins. If a request is refused, read the reasons and ask the NDIA about review options. Complex work may take a few months because assessment, quotes, approval and construction are involved.

Accessibility in a new build

For a new home, consider accessibility during the planning stage. This gives the participant, occupational therapist and design team a chance to consider how rooms, entrances and pathways will be used. Planning ahead can help identify access needs before construction makes changes more involved.

Discuss the participant’s daily activities and abilities before plans are finalised. For example, consider how they will enter the home, move between rooms and use the bathroom. An occupational therapist can assess needs and recommend design features. A functional assessment can also explain how proposed features support the participant’s goals.

Are quotes or builder estimates required for home modification funding?

For complex home modifications, builder quotes or cost estimates are usually needed before NDIS funding can be approved. An occupational therapist’s report describes the recommended work, while the builder’s quote sets out its construction scope and cost.

Builder quotes and tradesperson selection

A typical application includes an occupational therapist’s assessment, a report linked to the participant’s goals and a licensed builder’s quote. Submit these documents for approval before work begins. The quote should match the recommended scope, such as widening a doorway or changing a bathroom layout.

Participants may be able to choose their own builder if that person meets the requirements for the specific request. Confirm the requirements with the NDIA or the relevant plan contact before choosing a builder. For example, a builder quoting for grab rails needs to understand their intended location and how the modification supports safe use. The occupational therapist’s recommendations help communicate the purpose of the work.

Builder and project manager liaison

Complex work can involve an occupational therapist, builder, engineer and support team. The occupational therapist explains the functional recommendations, while the builder or project manager can clarify how the work will be carried out. This communication helps keep the construction scope connected to the participant’s needs.

If a builder identifies a practical issue, consider the proposed change alongside the assessment and funding request. For instance, an adjustment to doorway work may affect access through the home. Clear communication helps identify differences between the recommended work and the builder’s estimate before construction proceeds.

Builder quotes and construction

Once the quote and supporting report are ready, submit them for NDIS approval. Obtain approval before carrying out home modification work. Starting construction earlier may mean the work has not been approved for funding.

Complex modifications may take a few months because assessment, quotes, approval and construction are all part of the process. During that time, the quote and occupational therapist’s recommendations provide a shared reference for the work. They can describe its intended purpose, such as improving access to a shower or room to move safely.

Before moving from planning to construction, make sure the key documents tell a consistent story: the participant’s needs, the recommended modification and the builder’s proposed work. This helps everyone involved understand the purpose of each item.

Support at Home modifications

Support at Home and the NDIS are separate funding pathways, so first identify which one applies to the person and proposed work. An occupational therapy assessment can describe the person’s abilities, the barrier in the home and the change being considered. The report helps explain why a modification may assist with daily activities.

Clarify the pathway before planning work

Start by establishing which program the person is using and who will consider the request. NDIS participants should discuss plan-specific decisions with their support coordinator, plan manager or the NDIA. Someone considering Support at Home should use the relevant aged care pathway for information about their circumstances.

Don’t assume an assessment or approval under one program automatically applies to the other. The funding process, decision-maker and supporting documents may differ. Keep the proposed modification clear, such as an access change to a shower or a kitchen feature intended to support a daily task.

What the assessment and report should explain

An occupational therapist can assess how the person moves around the home and completes relevant activities. They consider the person’s abilities and environment, then recommend options that address the identified barrier. If a shower change is proposed, the report should connect it with the person’s needs in that space.

For a kitchen modification, the assessment can describe how the current layout affects a particular task and what change may help. The report should set out the recommendation and its purpose, giving the funding decision-maker information about the person’s needs and proposed work.

Confirm requirements before work begins

Before arranging home modification work, confirm the requirements of the relevant funding pathway. A recommendation in an occupational therapy report is not the same as funding approval, so don’t treat the report alone as permission to start construction.

Before work proceeds, make sure the approved scope matches the proposed change. If a builder’s estimate or design differs from the report, clarify the difference through the relevant funding pathway. Australian occupational therapists may recommend modifications that comply with building codes and NDIS design guidelines.

Keeping the pathway, assessment, report and approved work aligned gives each decision-maker a clearer picture. For help with NDIS-related next steps, Want to be a participant?

Frequently asked questions

What is the process for complex home modifications?

Complex modifications usually move through assessment, design and quoting, funding approval, construction, and a final check. An occupational therapist documents the participant’s needs and recommended work. A builder’s quote sets out the proposed construction scope, and an engineer may contribute to structural work. Keep the recommendations and quote aligned, and wait for approval before work begins. After installation, the occupational therapist checks whether the completed modification is safe and functional.

How do you determine which modifications are reasonable and necessary?

A recommendation should show how the proposed change relates to the participant’s disability and supports daily activities or independence. The assessment considers the person’s abilities, goals and home environment. It should explain why the suggested option is appropriate and cost-effective for the identified need. For example, a bathroom change should address a specific barrier to using that room, rather than express a general preference for renovation.

What are the NDIS eligibility rules for home modifications?

The NDIS supports people with permanent and significant disability, but eligibility for the scheme is separate from approval for a particular modification. A home modification request needs evidence linking the proposed work to the participant’s disability, needs and plan goals. The NDIA considers the request and relevant information. Talk with your support coordinator, plan manager or the NDIA about how your plan applies.

How do I get NDIS approval for home modifications step by step?

Begin with an occupational therapist’s assessment of the person’s needs, abilities and home environment. Then obtain a report explaining the recommended work and how it relates to the participant’s goals. For complex work, arrange a builder’s quote that matches the recommendation. Submit the assessment, report and quote through the relevant NDIS planning process. Wait for approval before construction begins, then arrange a check of the completed work.

What evidence and reports must an OT provide for an NDIS home modification request?

An occupational therapist’s report should describe the participant’s functional needs, relevant daily activities and barriers in the home. It should set out the recommended modification and explain how it relates to disability-related needs and goals. Diagrams or other details may help a builder understand the proposed work. For example, a doorway access report can explain which route is difficult and how the recommendation addresses that specific barrier.

What are the NDIS home modification funding limits and approval levels?

Minor modifications cost less than A$20,000 and are classified as Category A or Category B, depending on cost and other factors. Complex modifications cost more than A$20,000 or involve internal structural work. These thresholds describe categories, not a promise that a request will be funded. The NDIA considers the participant’s needs, evidence and plan when deciding a specific funding request.

How does the NDIS distinguish minor from complex home modifications?

The distinction depends on both cost and the nature of the work. Minor modifications cost less than A$20,000 and generally affect one or two areas in a home. Complex modifications cost more than A$20,000 or involve internal structural work. A ramp or grab rail may be a smaller change, while a structural bathroom redesign may be complex. The occupational therapist’s assessment helps describe the proposed scope and its purpose.

What are the risks, timelines, and appeal options if an NDIS home modification request is refused?

Complex modifications may take a few months because assessment, quotes, approval and construction are involved. If a request is refused, read the reasons and ask the NDIA about review options. Obtain approval before work begins.
