Australian dual occupancy home with two dwellings on one title, owner-occupied, for home insurance

Owner-Occupied Dual Occupancy Insurance

You live in one dwelling. Family or a tenant lives in the other, or there are two houses on the one title. Whether that is one policy or two depends on the roofline and who pays rent, and we work it out before anything is submitted.

THE SHORT ANSWER

An owner-occupied dual occupancy under one roofline, with separate entrances and no shared space, can generally be insured on one home policy that declares both households, with the landlord elements attached to the tenanted level if rent is paid. Two freestanding houses on one title are the harder case: some markets write both on one policy, and on two recent enquiries all but one of the markets that quoted would only do one policy per dwelling. Appetite is case by case.

Tank arranges this across Australia. The work is establishing the roofline, the occupancy of each dwelling and whether rent changes hands, then taking the property to the markets that write that structure, priced as one policy and as two where both are available, so you can see which is cheaper and which is cleaner.

01WHICH SETUP IS YOURS?

Four Ways an Owner-Occupied Dual Occupancy Gets Insured

The answer to "one policy or two" changes with the roofline, who lives in the second dwelling and whether rent is paid. Find your setup. Each has been placed or priced before, and appetite is confirmed case by case.

One house, you upstairs, a tenant or family downstairs

One building under one roofline with two self-contained levels, separate entrances and no shared space. This can usually sit on a home policy that declares both occupancies, with your contents on your level. If the other level is rented to a paying tenant, the landlord elements (loss of rent, tenant damage where selected) attach to that level, and not every home product accepts a tenanted dwelling on the title, so the mix is declared exactly as it stands and taken to the market that writes it.

What we need from you: Whether the two levels have separate entrances and no internal access, who lives downstairs, and whether rent is paid.

Two freestanding houses on one lot, both owner-occupied

This is the harder version. Some markets will write both dwellings on one home policy with both declared. Others will only quote one policy per dwelling, and on two recent enquiries all but one of the markets that quoted did exactly that. Two policies is not a failure; it is often the cleaner structure, with each house carrying its own sum insured and excess. What we work out first is which markets will take the pair as one, and whether that is actually cheaper.

What we need from you: The rebuild cost of each house, the year each was built, whether the second house has its own street address, and whether a subdivision is planned.

A granny flat with family in it, rent free

A secondary dwelling occupied by a relative without rent is still a second household on the title, and it has to be on the schedule. It generally rates as owner-occupied rather than tenanted, which keeps it inside more home products, but a policy that only knows about the main house may not respond for the flat. If the flat is rented, the landlord version on our granny flat insurance page applies.

What we need from you: Whether the flat is attached or detached, who lives in it, and whether any rent changes hands.

Subdivision planned or in progress

Two houses on one title today, two titles later. Until the plan registers, the property is insured as it legally stands, one title with two dwellings, and restructured into two policies on registration. The subdivision itself narrows the field, and the lender usually wants cover in the interim. That situation has its own page: home insurance while a subdivision is in progress.

What we need from you: Where the subdivision is up to, the lender's requirements, and the expected registration date.

02GETTING THE STRUCTURE RIGHT

Six Things That Decide Whether the Cover Actually Works

The second dwelling is not the hard part. It is making sure the policy describes the property, the households and the owner exactly as they are.

Declare Both Households

The insurer needs to know there are two households on the title, how each dwelling is occupied and whether rent is paid. A dwelling left off the schedule is a dwelling the policy may not respond for, and a tenant the insurer did not know about is a claim-time problem.

One Roofline or Two Buildings

Two levels under one roof with separate entrances can be presented as one free-standing home with two occupancies. Two detached houses are two dwellings, and that is where markets split between one policy and two. The presentation decides which products are even available.

Sum Insured Across Everything on the Title

The rebuild cost of both dwellings plus what is shared: the slab, driveways, fencing, retaining walls, services. On two houses, each needs its own rebuild figure even if they end up on one policy.

Contents Sit Where You Live

Your contents cover attaches to the dwelling you occupy. A relative's contents in the second dwelling are theirs to insure unless the policy is set up to include them, and a tenant's contents are never yours.

Separate Entrances and No Shared Space

The owner-upstairs-tenant-downstairs structure works when each level has its own entrance and there is no internal access between them. Shared kitchens or a single front door change it from two dwellings to one house with a boarder, which is a different product conversation.

The Lender on the Right Policy

If two policies are issued, the lender's interested-party note has to appear on both, and the certificate of currency for settlement or refinance has to show both dwellings. A certificate for one house on a two-house title gets sent back by the bank.

What it costs: recent placements and quotes for owner-occupied dual occupancies have run from approximately $3,700 to $6,600 a year as one policy, and around $6,300 to $10,200 combined where two freestanding houses were quoted as two. Your property will be rated on its own details. See the home insurance cost guide.

01 Owner in one side, tenant in the other, one policy for the building

An owner on the NSW mid-north coast lives in one side of a house built as an approved dual occupancy, with separate entrances, and rents the other side to residential tenants. Building sum insured $1.45 million, solar on the roof.

The brief was building cover for the whole structure, landlord cover with loss of rent on the tenanted side, and the owner's contents on their own side. The owner-plus-tenant mix was declared exactly as it stands, because that mix is what each market rates.

THE RESULT:

Placed with CGU at approximately $6,600 a year, covering the whole building with loss of rent on the tenanted side, after three markets quoted and one declined.

02 Two freestanding houses on one title: what the market actually said

Two recent enquiries, one in Sydney's north-west and one in Perth, each involved two separate owner-occupied houses on a single title with rebuild costs of around $1 million and $790,000 for the main dwellings. Both owners wanted one policy.

One enquiry drew three quotes, from around $6,300 to $10,200 combined, every one of them as two policies. The other drew four, from around $6,600 to $7,600, and there the one market that offered a single combined policy was the cheapest of the four. Two markets declined across the pair.

THE RESULT:

Neither owner went ahead at the time. Two freestanding houses on one title are placeable, more often as two policies than one, and worth pricing both ways before deciding.

OWNER-OCCUPIED DUAL OCCUPANCY FAQS

Common Questions When You Live in One of Two Dwellings

01 I live upstairs and rent out downstairs. Is that a home policy or a landlord policy?

Both, on one policy where the product allows it. Your level is owner-occupied with your contents; the downstairs level is a tenanted dwelling with the landlord elements attached to it. The condition is that the two levels are genuinely separate: their own entrances, no internal access, no shared living space. Not every home product accepts a tenanted dwelling on the title, so the structure is declared and taken to the market that writes it rather than pushed through an online form that assumes one household.

02 Can two houses on one title go on one home insurance policy?

Sometimes. Some markets will write both dwellings on one policy with both declared. On two recent enquiries, all but one of the markets that quoted would only do one policy per dwelling, and the one single-policy quote happened to be the cheapest on its enquiry. Two policies is not worse cover; each house gets its own sum insured and excess and the lender is noted on both. We price it both ways where both are available and tell you which is cheaper and which is cleaner.

03 My parents live in the second dwelling rent free. Does that count as a tenant?

Not usually. A relative living in the second dwelling without paying rent is generally rated as owner-occupied rather than tenanted, which keeps the property inside more home products. It still has to be on the schedule as a second household, and their contents are theirs to insure unless the policy is deliberately set up to include them.

04 What if the second dwelling is a detached granny flat?

It is declared as a second dwelling on the one policy, with the building sum insured covering both structures and everything between them. Rent free with family in it, it rates as owner-occupied. Rented, it becomes a landlord element and the granny flat insurance page covers that version.

05 How much does insurance cost for an owner-occupied dual occupancy?

Recent placements and quotes have ranged from approximately $3,700 for a two-dwelling property insured for $1 million building only, to approximately $6,600 for a $1.45 million one-roofline dual occupancy with the owner in one side and a tenant in the other, to around $6,300 to $10,200 combined where two freestanding houses were quoted as two policies. Sum insured, whether it is one roofline or two buildings, who lives in the second dwelling and the excess move the figure. See the home insurance cost guide.

06 How fast can this be arranged for settlement?

With all the information in hand, cover can be arranged in as little as 24 hours; usually it takes 48 to 72 hours, because the markets that write two dwellings on one title need the occupancy detail and the rebuild value of each dwelling before they release terms. Send the settlement date with the enquiry so it is prioritised, and the certificate of currency follows as soon as the policy is bound.
