Logan Granny Flat Infrastructure Charges Cut: What It Means for Owners and NDIS Housing

By Cesar Perilla | Director - Local Property Team No Limits
Published: 8 October 2026

Logan City Council has voted to halve infrastructure charges for one-bedroom granny flats, potentially reducing the upfront cost of an eligible project by $13,500.

According to ABC News, the charge will fall from $27,000 to $13,500, with the changes expected to commence in November 2026. Owners should confirm the commencement date, eligibility conditions and charge applicable to their property before including the saving in a project budget.

For owners considering a secondary dwelling in Logan, the reduction could improve project feasibility. It also creates an opportunity to consider how well-designed smaller homes could support family members, renters and people living with disability.

At Local Property Team, we help owners investigate these options by considering the site, the intended residents, the completed cost and the ongoing management requirements.

What Does the Logan Granny Flat Infrastructure Charge Reduction Mean?

Infrastructure charges help fund the infrastructure needed to support additional development. Reducing this charge could lower one of the upfront expenses associated with an eligible granny flat.

The reported decision concerns one-bedroom secondary dwellings. Owners considering a two-bedroom design should confirm the applicable charge rather than assume the same reduction will apply.

Logan City Council explains that the relevant charges resolution depends on the timing of the development approval, decision stage or lodgement of building approval documents. Owners can request a project-specific estimate from Council.

The practical starting point is to establish what can be built on the site and which charges will apply to that proposal.

How Can Owners Build a Better Granny Flat in Logan?

The announcement has prompted debate about overcrowding and the quality of backyard development. A lower infrastructure charge does not remove the need for thoughtful site planning.

Our view is that a successful secondary dwelling should provide a comfortable home while preserving the liveability of the existing property. Important considerations include:

• Separate access and privacy for both households.

• Suitable parking and safe pedestrian access.

• Usable outdoor space, fencing and landscaping.

• Drainage, service connections and waste collection.

• The effect on the main home’s rental appeal.

• Access for support workers where specialist accommodation is proposed.

The aim should be to create two homes that work well together. A compact dwelling can support independence and dignity when its layout, access and surroundings suit the people who will live there.

Could an Accessible Granny Flat Support an NDIS Participant?

An accessible secondary dwelling may allow a person with disability to live close to family while maintaining their own space. Depending on their needs and funding arrangements, they may receive support in that home.

However, an accessible granny flat is not automatically Specialist Disability Accommodation (SDA).

SDA is specialised housing for eligible participants with extreme functional impairment or very high support needs. Other NDIS participants may live in ordinary housing with appropriate supports.

New SDA dwellings require the relevant design certification and must satisfy NDIA enrolment requirements, alongside applicable planning and building requirements. Design certification alone does not guarantee SDA enrolment: the NDIA assesses the completed dwelling and provider against its requirements.

Owners should establish the intended housing model before selecting a floor plan or committing to construction. An accessible home for a family member, a standard rental and an SDA dwelling involve different requirements.

What Is the Difference Between SDA Housing and SIL?

Specialist Disability Accommodation concerns the housing itself. Supported Independent Living (SIL) funds support workers who help eligible participants with daily activities and supervision.

SIL funding does not pay rent. Housing costs and support funding need to be assessed separately.

Where an owner proposes leasing a property to a support provider, the accommodation agreement should clearly establish the rent, lease conditions, maintenance responsibilities and other obligations.

Understanding this distinction helps owners assess a proposal realistically. A potential resident’s support funding should not be treated as a guarantee of rental income.

What Specialist Housing Options Is Local Property Team Exploring?

Through our specialist accommodation work, Local Property Team is investigating compact modular and transportable dwellings with manufacturers, designers, assessors and providers.

One concept under consideration is adding a purpose-designed SDA dwelling to a suitable existing property, with the main house potentially used for compatible supported accommodation.

Each proposal requires assessment of the site, residents’ needs, provider arrangements, planning permissions and SDA requirements. A transportable building alone does not establish an approved accommodation model.

We are also exploring accessible secondary dwellings for owners and family members who need a more practical home, regardless of whether SDA funding applies.

The focus is on identifying a suitable housing solution and assessing its feasibility before committing to a particular building.

What Should Owners Include in a Logan Granny Flat Budget?

A reduced infrastructure charge is only one part of the overall cost. When comparing conventional, modular, transportable or expandable granny flats, owners should allow for:

• The dwelling and its included fit-out.

• Foundations, engineering and site preparation.

• Transport, crane hire and installation.

• Electricity, water, sewer and stormwater connections.

• Approvals, certification and applicable Council charges.

• Paths, fencing, landscaping and outdoor areas.

• A contingency for unforeseen work.

The useful comparison is the total cost of an approved, installed and connected dwelling ready for occupation.

Rental expectations should reflect the completed layout, location and local market. Additional internal space may improve tenant appeal without necessarily producing a higher rent.

Specialist housing projections also require assessment of participant eligibility, provider demand, vacancy and ongoing operating costs. These factors should be considered alongside the construction budget.

Frequently Asked Questions About Logan Granny Flats and NDIS Housing

Does the charge reduction apply to two-bedroom granny flats?

The reported decision concerns one-bedroom secondary dwellings. Confirm the charge for a two-bedroom proposal directly with Logan City Council before adjusting your budget.

Can a granny flat qualify as SDA?

Potentially, if the dwelling and provider meet the relevant SDA design and enrolment requirements. An accessible layout or building approval alone does not establish SDA eligibility.

Does every NDIS participant need to live in SDA?

No. SDA is intended for eligible participants with particular high support needs. Other participants may live in ordinary housing with appropriate supports.

Where should a property owner start?

Start with a site assessment, an intended housing model and a complete project budget. If specialist accommodation is proposed, involve the relevant assessor and provider before committing to a design.
