Building a Granny Flat in 2026
New rules explained
New rules. Less red tape. Your granny flat might be closer than you think. 🏡
Most people even builders — aren't fully across the new minor dwelling rules yet.
In many cases, if your build meets four key conditions, you may not need a full building consent. This applies across New Zealand.Watch Ramin and Darren explain the key points.
Granny Flats in NZ Just Got Bigger
70sqm sounds small - but here's what most people don't realise. That's measured to the internal lining, which means the actual build is closer to 73–75sqm externally. And if you push the design smartly, you can go even further. In many cases, if your build meets four key conditions, you may not need a full building consent. This applies across New Zealand. Watch architect Darren Gubb break down the new size rules.
How a granny flat puts $10,000 in your pocket every year
Could your granny flat pay for itself? A well-planned granny flat could put $5,000–$10,000 in your pocket every year - while your tenant helps cover the costs. And that's before you factor in the long-term value of your property. If you meet specific conditions, subdividing in the future could unlock even greater value - but it's important to plan for it before you start building. This applies across New Zealand. Watch Ramin and Darren explain the key points.
Why Your Granny Flat can Pay for Itself
Thinking about building a minor dwelling but not sure if you can afford to finance it? Yield: 6.5% vs Auckland average of 3.5–4%. Positive cash flow from day one - plus the potential to subdivide later. Not sure if it works for your property? Andrew says they can run the numbers with you in just 15 minutes.
