What Does the Data Say? Australia's Granny Flat Boom, Explained
August 17, 2026
Australia is experiencing a genuine granny flat boom, and the data tells an interesting story about why.
The Numbers
Search interest in "granny flat" has increased steadily over the past five years, with a notable spike in 2025–2026. Building permit applications for secondary dwellings are up across most Australian states.
What's Driving the Boom?
Three factors: housing affordability (or lack thereof), an ageing population needing family-close accommodation, and growing acceptance of higher-density living in suburban areas.
Investment Perspective
According to independent finance media like Mozo.com.au, Australians are increasingly searching for properties with granny flats and gardens — suggesting these features add genuine market value.
