What are home modifications?

Home modifications are any changes to your existing home, which improve its accessibility for people with disability.

For example: installing a grab rail next to the toilet or widening a doorframe so a person using a wheelchair can fit through it.

Home modifications fall into two categories, minor home modifications and complex home modifications.

Minor home modifications

Minor home modifications are those which cost less than $20,000 or those that don’t alter the structural parts of the home (walls).

Complex home modifications

Complex home modifications are those which cost more than $20,000 or those which involve changing the structure of your home, i.e., knocking down a wall to increase the size of an existing room.

Examples of complex home modifications

  • Enlarging a room space for wheelchair and/or other equipment use
  • Creating a level access shower so that a person can wheel straight into the shower space
  • Having a ceiling hoist installed so the client can move out of bed
  • Widening doorways to make negotiating narrow doorways easier
  • Installing complex ramps or platform lifts for safe and independent access to the home
  • Kitchen modifications to improve independence and safety with meal preparation
  • Home automation – automated doors, lighting, power control, climate control, etc to improve independence with environmental control.

What is the process for complex home modifications?

  1. An OT assesses your home and your level of function to determine need for minor or complex home modifications
  2. OT makes recommendations in a report to recommend complex home modifications (CHM)
  3. Once approved by NDIS – CHM OT will complete a home visit to determine appropriate modifications
  4. CHM OT and Project Manager will then work together to complete drawings, scope of works and costings
  5. CHM OT will complete complex home modification report and submit all documentation to NDIS
  6. Once approved by NDIS – Project Manager will organise quotes from builders and submit to NDIS for approval
  7. Works commence – Project manager oversees works are completed according to CHM OT’s plans
  8. Project manager and CHM OT review final modifications

What people and skills are required for complex home modifications?

Many people are required to complete complex home modifications including:

  1. The client/you – we need to know how to meet your needs and what your preferences are
  2. An occupational therapist – they will make recommendations for what home modifications are required for you
  3. Building Works Project Manager- they will work with your occupational therapist to design modifications that are safe, functional, and match your personal preferences
  4. Builder or contractor- they are responsible for carrying out the modifications according to the design and ensuring that the modifications meet building standards and regulations
  5. Construction specialists- depending on the type of construction plumbers, electricians or specialist carpenters may be required
  6. The NDIS, who provide funding for the Complex Home Modification process and works

The timeline for complex home modifications

Complex home modifications often involve multiple stages, which require NDIS approval and a number of professionals, trades, and services to be coordinated. When organising these modifications, it’s important to be aware that there can be an extended timeframe for builders to complete the work. Your Complex Home Modification OT will work with you during this process so that you’re fully informed.

How much will complex home modifications cost from my NDIS plan?

The cost will vary depending on the modifications you require. The cost of an OT complex home modifications assessor is $193.33 per hour. This funding will come from your capacity-building budget.

The cost of the actual modifications including tradespeople will come from your capital support budget once home modifications are approved in your plan.

We generally state 20 OT hours to complete the complex home modifications, however, this can vary depending on the complexity of the modifications.
