Granny Flat Builders in Carramar: When Mum and Dad Help Pay for It

Mum and Dad are paying for the granny flat. Get the paperwork right first.

A lot of Carramar families build a granny flat so parents can live close by, and often the parents put in the money, sometimes from selling their own home. That's a generous arrangement. It also has pension, legal and family consequences that are much easier to sort before the slab than after.

Short answer

Does paying for a granny flat affect Mum and Dad's age pension?

It can. Centrelink has specific rules: parents who pay for a flat on their child's land may be treated as holding a granny flat interest, which affects how the pension and any gifting are assessed. Get advice and put the arrangement in writing before building. In Carramar, code-compliant flats up to 60m² can be approved quickly, and construction runs about $2,090 to $2,520 per m².

Fact-checked

Centrelink has a rule for exactly this

When someone on the age pension, or who expects to be, pays for the right to live in a granny flat for life, Services Australia can treat it as a granny flat interest. That can be done by paying for the flat's construction, or by transferring their own home or assets to a family member in exchange.

How it's treated matters for the pension. Services Australia applies a reasonableness test to the amount paid. If you pay more than it considers reasonable, the excess can be counted as a gift and affect the pension for years.

I'm a builder, not a financial adviser. Services Australia runs a free Financial Information Service, and a family should talk to them, and to a lawyer, before the money moves.

The flat takes twelve weeks to build. A bad family arrangement can last twenty years.

Put the arrangement in writing

The granny flat sits on your title, not your parents'. In NSW it can't be subdivided off. So it's worth setting out in writing who paid what, what happens if the house is sold, if the relationship breaks down, or if a parent needs to move into care.

A lawyer can draw up a family agreement that covers it. Families who do this rarely need it. Families who don't sometimes wish they had.

  • Who paid for the flat, and how much
  • The parents' right to live there, and for how long
  • What happens if the main house is sold
  • What happens if a parent moves into aged care
  • How costs like rates and maintenance are shared

A flat that works at 70 and at 90

If the flat is for parents, design it for later life from day one. A level path from the car to the door. A hobless shower with room to turn, and wall reinforcement for grab rails. Wider doorways. Lever handles, bright lights on the path. Done well, it simply looks like a nicely built small home.

Carramar sits beside the rail line, so put the bedroom on the quiet side of the flat and away from the tracks. If the lot is close to the corridor, acoustic glazing may be needed anyway.

Approval and cost in Carramar

Where the residential lot is larger than 450 square metres and the design satisfies the state housing code, approval comes from a certifier rather than Fairfield Council. Most Carramar lots sit right around that size, so yours is worth measuring properly.

Fairfield's 0.95 factor on the Rawlinsons Sydney schedule puts construction near $2,090 to $2,520 per square metre for mid-range finishes. Flat, connections and services go on one fixed contract, so the family has the real number before anyone signs an agreement.

Granny flats for parents

Does paying for a granny flat affect the age pension?

It can. Services Australia has specific granny flat rules and applies a reasonableness test to the amount paid. Get advice from their Financial Information Service before committing.

Who owns a granny flat on my land?

Legally, it's part of your property and on your title. That's why a written family agreement about rights and money is worth having.

Does council have to approve a Carramar granny flat?

Not always. When the design meets the state housing code and the lot is big enough, a certifier signs it off. Otherwise it goes to Fairfield Council as a DA.

Can the granny flat be rented out later?

Yes. If circumstances change, a granny flat can be leased, subject to NSW tenancy law and minimum rental standards.
