Can I Rent Out a Granny Flat in NSW?

What needs to be true before you rent it out

Renting out a granny flat rests on the dwelling being a legitimate, approved place to live. In practice, that means the secondary dwelling was approved as a dwelling, was built to the standards that applied, and is being used the way it was approved to be used.

If any of those is missing, renting it out may carry risks, and the safest step is to confirm the position rather than assume it. The status of the dwelling, not your intention to rent, is what determines whether rental use is on solid ground. In practical terms, the dwelling should be formally approved and suitable for someone to live in, not just informally built or used as a home, since informal use does not make it an approved rentable dwelling.

Approved granny flat vs unapproved dwelling

This is the distinction that matters most. An approved secondary dwelling is one that holds the planning and building approval it should, and is used as approved. An unapproved dwelling is a structure that lacks that approval, or was approved as something else, such as a shed or studio, and later used as a home.

Renting out an approved secondary dwelling is generally the straightforward case, subject to the usual checks. Renting out an unapproved dwelling is where problems arise, because using an unapproved structure as rental accommodation can carry legal, safety and insurance risks. If you are unsure which describes your granny flat, confirm its status through council records before doing anything that relies on it being rentable. Our guide on an unapproved granny flat in NSW explains the risks and how owners commonly resolve them.

Rules and approval checks to confirm first

Before advertising, it is worth confirming a few things for your specific property:

• Approval status. Whether the granny flat is an approved secondary dwelling, confirmed through council records rather than assumption.
• How it was approved. Whether it was approved as a dwelling, and whether current use matches that approval.
• Council rules. Whether any local controls affect how a secondary dwelling can be used in your area, since these can vary by council.
• Building compliance. Whether the dwelling meets the construction and safety standards expected of a home.

For the detailed rules a compliant secondary dwelling is measured against, see what the rules require in NSW. If you need to understand how approval itself works, our granny flat approval process page covers the pathways. This article stays focused on the question of renting, and points to those pages for the underlying detail.



Insurance, safety, and practical rental considerations

Beyond approval, there are practical matters worth looking into before a tenant moves in. These are general considerations, not advice, and the specifics depend on your circumstances and the professionals you engage:

• Insurance. It is worth checking with your insurer how renting out a granny flat may affect your cover, since an unapproved or undisclosed dwelling can complicate things.
• Safety. A rented dwelling should be safe and suitable to live in, which is a reason building compliance matters.
• Rental compliance. Renting out property in NSW comes with obligations, so it is sensible to understand what applies before you start.
• Shared arrangements. Where the granny flat shares access, services or metering with the main house, it helps to think through how that works for a tenant.

Because insurance, tax and tenancy each have their own rules, these are areas to raise with the relevant professional rather than assume. The aim here is simply to flag what to look into.

What not to assume before advertising

A few assumptions cause the most trouble:

• Assuming approval. Believing the granny flat is approved without confirming it in council records.
• Assuming use is covered. Thinking a structure approved as a studio or shed can be rented as a dwelling.
• Assuming insurance carries over. Expecting existing cover to extend to a rental arrangement without checking.
• Assuming council rules do not apply. Overlooking local controls that can affect secondary dwelling use.
• Advertising first, checking later. Listing the dwelling before the position is confirmed.

Confirming the facts before you advertise keeps you on safe ground and avoids awkward surprises once a tenant is involved.

How this differs from looking for a granny flat to rent

This guide is for owners asking whether they can rent out their own granny flat. If instead you are looking to rent a granny flat to live in, that is a different need. You can browse available options on our granny flats for rent in Sydney page.

Keeping the two apart matters because the checks an owner needs to make before renting out a dwelling are quite different from what a prospective tenant is looking for.

Frequently asked questions

Can I rent out my granny flat in NSW?

You may be able to, provided the granny flat is an approved secondary dwelling, meets the relevant planning and building requirements, and is safe and suitable to live in. The key first step is confirming its approval status through council records rather than assuming it. If it is approved as a dwelling and complies, renting it out is generally possible subject to the usual checks around insurance and rental obligations. If it is unapproved or its status is unclear, that needs resolving before you advertise or take tenants, so the answer depends on your specific property.

Can I rent out a granny flat that was approved as a studio or shed?

Renting a structure as a home when it was approved as something else, such as a studio or shed, is where problems commonly arise. Approval generally covers a specific use, so a building approved as a shed is not automatically approved to be lived in. Using it as rental accommodation could carry legal, safety and insurance risks. The reliable step is to confirm what the structure is actually approved for through council records, and get advice on whether it can be used or regularised as a dwelling, before treating it as rentable.

Do I need council approval to rent out a granny flat?

The approval that matters is the approval of the granny flat as a secondary dwelling in the first place. If it is already an approved dwelling that complies with the relevant requirements, renting it out is generally about meeting the usual rental and insurance obligations rather than seeking fresh planning approval. Some council rules can affect how a secondary dwelling is used, and these vary by area, so it is worth checking your local position. If the dwelling is not approved, that is the issue to resolve first.

Is it a problem to rent out an unapproved granny flat?

Renting out an unapproved granny flat can carry real risks, including legal, safety and insurance consequences, and it is not something to do on the assumption it will be fine. An insurer, a council query or a tenancy issue can bring the approval status to light at an inconvenient time. Rather than proceed and hope, confirm the dwelling's status through council records and get advice on your options. If it turns out to be unapproved, resolving that comes before any rental use.

Can I use a granny flat for short-term rental or Airbnb?

Possibly, but short-term rental is treated differently from a standard tenancy, so it should not be assumed. NSW has short-term rental accommodation rules, and council controls, any strata rules, and your insurance can all affect whether and how a granny flat can be used this way. These vary by area and situation. Before listing a granny flat for short-term stays, it is worth checking the short-term rental rules that apply, your council's position, any strata requirements and your insurer, rather than relying on the dwelling simply being approved as a secondary dwelling.

Does renting out a granny flat affect my insurance?

It can, which is why checking with your insurer is worth doing before a tenant moves in. Renting out a dwelling changes how a property is used, and an unapproved or undisclosed granny flat can complicate cover or a future claim. Insurance is specific to your policy and circumstances, so this is a matter to raise directly with your insurer rather than assume. This guide flags it as something to confirm, not as insurance advice.
