Does a SIL participant need to be on the lease for NDIS compliance?

Not necessarily, but the arrangement must be documented clearly. If a housing provider holds the lease, the SIL provider must ensure the participant has a sub-tenancy agreement or equivalent arrangement that gives them documented tenancy rights, and there must be evidence the participant understands and has accepted this arrangement.

How often does a SIL property accessibility assessment need to be updated?

There is no single mandated frequency in the Practice Standards, but auditors generally expect assessments to be current — typically within twelve months — and to reflect the actual functional needs of the participants currently living in the property. A significant change in participant cohort or a property modification should also trigger a fresh assessment.

Can a SIL provider set house rules for all residents in a shared property?

Yes, but house rules must be co-developed with participants, not imposed unilaterally. Auditors will look for evidence of participant involvement in creating and reviewing the rules, and will flag any rule that operates as a de facto restrictive practice without proper authorisation under a participant's behaviour support plan.

What happens if a maintenance issue at a SIL property is linked to a participant incident?

Auditors will expect to see that the incident report identified the environmental factor, that a corrective action was raised in the maintenance register, and that the action was completed within a reasonable timeframe. Repeated incidents linked to unresolved maintenance issues are a significant audit finding.

Is a generic transition plan acceptable for SIL audits?

No. The NDIS Practice Standards require transition plans to be individualised. A template is a starting point only — it must be completed with the specific participant's risks, support needs, named key contacts, and agreed timelines. An auditor who sees an identical transition plan across multiple participants will raise a non-conformance.

What documents should be in a per-property SIL audit file?

A well-organised per-property file should contain the current lease or title documentation, an up-to-date accessibility assessment, fire evacuation plan (naming each resident), maintenance log with open/closed status, safety certification records (for example, smoke alarm checks), and the current household agreement with evidence of participant input.

SIL property and tenancy: documentation an auditor expects

Why property and tenancy documentation matters for SIL audits

Supported Independent Living (SIL) is among the most scrutinised NDIS support categories precisely because it intersects where people live, how they are supported, and whether they retain genuine autonomy. Under the strengthened NDIS Practice Standards and the registration requirements that applied from late 2023 and continued to be reinforced through 2025–2026, registered SIL providers must demonstrate — not merely assert — that their documentation upholds participant rights and complies with the Commission's expectations.

When an approved quality auditor arrives for a certification or verification audit, they are looking for a coherent evidence trail. Gaps in tenancy documentation are among the most common non-conformances auditors record against SIL providers. This article maps exactly what auditors expect to find, where they look, and the common mistakes that lead to findings.

The auditor's lens: what Practice Standards apply

The NDIS Practice Standards that are directly relevant to property and tenancy documentation in a SIL context include:

Rights and Responsibilities — participants must be informed of their rights, including rights as a tenant.
Individualised Supports — support delivery must reflect each person's goals, preferences, and living situation.
Support Provision Environment — the physical environment must be safe, accessible, and appropriate.
Transitions to/from the Provider — planned, documented transitions in and out of SIL arrangements.
Human Rights (strengthened framework) — the 2026 strengthened standards place heightened emphasis on participants' right to choose where and with whom they live.

Auditors cross-reference your documentation against these modules. A document that exists but does not link to an identifiable participant outcome will not satisfy the standard.

Exactly what an auditor checks: the document-by-document walkthrough

1. Tenancy agreements and lease documents

Auditors will ask to see the current signed lease or tenancy agreement for every SIL property. They check:

Whether the agreement is in the participant's name (or a housing provider's name with a sub-tenancy arrangement clearly documented).
That the participant — or their legal guardian or nominee — signed the agreement voluntarily, not the SIL provider on their behalf without authorisation.
That the participant has been given a copy in an accessible format (easy read, large print, verbal explanation documented).
That the agreement does not contain terms that unlawfully restrict the participant's rights as a tenant under the relevant state or territory residential tenancy legislation.

A frequent non-conformance: the SIL provider holds the lease and there is no documented evidence the participant understands their tenancy rights or has been offered independent advice about the arrangement.

2. Property accessibility and safety assessments

Every SIL property requires a documented assessment confirming it is appropriate for the people living there. Auditors look for:

A current (not more than twelve months old unless a major refurbishment has occurred) accessibility assessment signed by a qualified assessor or occupational therapist.
Evidence that the assessment matches the functional needs of the current participants — not a generic assessment written for a previous cohort.
Fire safety compliance certificates, including evacuation plans that name each participant and account for mobility and communication needs.
Records of any modifications made to the property and the authorisation trail (landlord consent, funding approval, participant sign-off).
Maintenance logs demonstrating the property is kept in a state of good repair, with actions tracked to completion.

3. House rules and household agreements

Auditors are increasingly attentive to how house rules are developed and whether they are proportionate and rights-respecting. The strengthened 2026 framework explicitly raises the bar here. Auditors expect to see:

Documented evidence that house rules were co-developed with participants, not imposed by the provider.
Minutes or notes from house meetings where rules were discussed and agreed.
Review dates on household agreements — a static document from three years ago with no review is a flag.
Confirmation that no house rule operates as a de facto restrictive practice (for example, blanket curfews or visitor bans without individualised justification and proper authorisation).

4. Choice and control evidence

This is the area where providers most often struggle to produce sufficient documentation. Auditors will ask: how do you know this person is living where they want to live, with whom they want to live? Acceptable evidence includes:

Documented conversations or preference-capture records (dated, signed or witnessed) showing the participant actively chose their current living arrangement.
Evidence that the participant was offered meaningful alternatives, not just presented with a single vacancy.
Records of participant feedback, complaints, or compliments relating to their home — an absence of any feedback mechanism is itself a finding risk.
Support plans that clearly separate housing goals from support goals, with participant voice evident in both.

5. Transition and exit documentation

Transition planning is a dedicated module in the NDIS Practice Standards and auditors will pull transition files for both new entrants and recent exits. They check:

A written transition plan prepared before the participant moved in, identifying risks, supports required, and the planned timeline.
Evidence that the participant (and their support network where appropriate) was involved in developing the transition plan.
For exits: a documented exit plan that includes housing continuity — the auditor will want to know what happened to the person's tenancy when they left your service.
Any incident reports linked to the transition period and how they were managed.

6. Incident and restrictive practice records linked to the property

Auditors correlate your incident register with the property addresses in your SIL portfolio. They look for:

Any incident classified as occurring "in the home" and whether the environment contributed to the incident (for example, inadequate supervision layout, unsecured hazards).
Any restrictive practice that operates at the property level (locked external doors, limited access to certain areas) and whether it is properly authorised under the participant's behaviour support plan and state/territory approval mechanisms.
Evidence that environmental factors identified in incident reviews have triggered property maintenance or modification actions.

Common non-conformances and how to fix them

Non-conformance	Fix
Lease is in provider's name only; participant has no documented tenancy rights	Implement a sub-tenancy deed or equivalent; provide participant with a rights summary in accessible format
Accessibility assessment is generic or out of date	Commission individual assessments annually or on change of participant cohort; store in participant file
House rules document has no review date and no evidence of participant input	Re-run household agreement process with meeting minutes; set 6-monthly review cycle
No documented evidence participant chose this property	Introduce a "Housing Preference and Choice" form completed at intake and reviewed at each plan review
Transition plan exists but is generic, not participant-specific	Template must be completed with participant-specific risks, timelines, and named supports
Maintenance requests not tracked to resolution	Implement a maintenance register with open/closed status; link unresolved items to participant risk assessment

Building your audit-ready property documentation system

The most defensible position in an audit is a consistent, retrievable document system — not a folder of assorted PDFs. Consider organising property documentation into a per-property file and a per-participant file, with a cross-reference index that an auditor can follow without your guidance.

A per-property file typically contains: the lease or title documentation, accessibility assessment, fire evacuation plan, maintenance log, safety certification records, and the household agreement.

A per-participant file contains: the participant's tenancy rights acknowledgement, their housing preference and choice record, their individual support plan (housing section), transition plan, and any property-linked incident records or restrictive practice authorisations.

If you are building this system from scratch ahead of an audit, ndiscompliant.com.au offers a 74-document audit-ready SIL compliance kit that covers property, tenancy, and the broader Practice Standards — a practical starting point for providers who need to close multiple gaps quickly.

The 2026 strengthened framework: what has changed

The strengthened NDIS Practice Standards place greater emphasis on human rights, participant voice, and provider accountability. For property and tenancy specifically, this translates to a higher evidentiary standard around choice and control — auditors are no longer satisfied with a tick-box confirming "participant was consulted". They expect to see dated records, the participant's own words or expressed preferences, and evidence of what changed as a result of that consultation. Providers who built their documentation systems before the strengthened framework was embedded should review their tenancy and housing documentation templates against the updated standards.
