Is My Property Suited For A Designer Granny Flat?

One of the most common questions we are asked about our designer granny flats is ‘does my backyard meet the requirements for a granny flat to be built?’ Some of the minimum site requirements for a granny flat to be approved as a complying development include:

Minimum Block Size

Your block must have a minimum of 450m² to qualify.

Property Setback

You must maintain a 3m setback from the rear and 0.9 from side boundaries. For larger blocks the boundary setbacks increase.

Residential Zoning

Your block of land must be zoned residential – R1, R2, R3, R4.

Existing Trees

All granny flats must be located a minimum distance of 3m from any existing trees that are over 4m in height.

Your block of land must have 12m width at the building line of the existing dwelling.

Floor Area

Your granny flat floor plan must have a maximum 60m² external area.

Granny Flat Investments

Granny flats are a great investment addition to a property portfolio. We can say this confidently, as we have seen dozens of our clients get a positive return on their investment.

The team at Mortgage Partners Australia have looked into this in detail and found that it’s a great way to convert a negatively geared property to positively geared, with minimal capital outlay. They lay out a scenario whereby the yield of the example property shifts from 8.59% to 15.18% with the addition of a granny flat 100 per cent financed at $125,000.

A granny flat can provide:

  • A positively geared investment, giving you an extra $195 each week in your hand or $10,000 per year.
  • Rental yields of 15% each year.
  • Tax depreciation benefits of up to $6,000 per year.
  • A tangible asset that you can see and touch.
