Granny flats have moved from niche to mainstream across Australia, with around 4,000–6,000 built each year and demand accelerating. Growth was unlocked in 2009, when NSW streamlined approvals — a model since followed by Queensland, Victoria, South Australia and Western Australia, as rules around secondary dwellings and rentals were relaxed.
Today, with 100+ specialist granny flat manufacturers and modular builders operating nationally, granny flats are one of the fastest and most practical ways to add housing, income, and value — without subdivision
Our Granny Flat/Secondary Dwelling journey began 5 years ago. Yes, a passion for developing our investment property portfolio, a Google Earth snip and an email to a certifier. Funny thing is, they said "no"😕 2 years ago, I found out that some certifiers know a lot more about Granny Flat/Secondary Dwellings than others. I tried one of these...and they said "yes". This is a key learning: in the Granny Flat/Secondary Dwellings space, a good certifier can often find a solution, where others can't! Can I Granny Flat has already done your hard yards here.
Most granny flat builders bundle certification into their costs — often at a healthy margin — and once you’ve started, you’re effectively locked in. Even if the answer is no.
