Why Brisbane homeowners choose a granny flat
Right across Brisbane, families are discovering just how much a granny flat can do. On a single existing property, it can be:
- Space for family. Keep mum and dad, ageing parents or adult children close by, with comfortable accommodation and their own space.
- A retreat for the kids. Give a teenage son or daughter room to grow, and the rest of the household a little more peace.
- An investment property. Generate rental income from a self-contained dwelling, with strong demand from tenants across Brisbane.
- Long-term value. A quality granny flat adds lasting value and broad appeal, helping build long-term wealth and financial freedom.
It’s extra space, extra options and extra value, without the cost and upheaval of moving house.

A smart investment in Brisbane
For many Brisbane homeowners, a granny flat simply makes good financial sense. A well-designed granny flat can add up to around 30% to your property’s value, and because properties with a secondary dwelling are increasingly attractive to buyers, it can be a smart long-term play as well as a comfortable one.
There’s income potential, too. Rental returns vary with the market, but a quality granny flat can generate meaningful additional weekly income, unlocking a second revenue stream from space you already own. As an investment in both lifestyle and value, it’s hard to beat.

Brisbane granny flat rules and approvals
Building a granny flat in Brisbane is often more straightforward than people expect. Brisbane City Council regulates granny flat approvals, and in many cases a granny flat is considered accepted development, meaning it can proceed without separate planning approval, provided it meets the relevant criteria. A few key rules apply:
- A granny flat generally must not exceed 80m² in size
- If it’s under 80m² and intended for household members, special council approval may not be needed
- A Development Application is required if the granny flat exceeds 80m² or sits more than 20 metres from the main house
- It must provide one off-street car space, in addition to parking for the main house
- It must include its own kitchen, bathroom and toilet, on the same property title as the main house
Council lot-size and site-coverage requirements also apply, and your property’s zoning can affect what’s possible. Every granny flat needs a building permit and must comply with standard safety, fire and building regulations. It can sound like a lot, which is exactly why we handle it for you, our team checks what applies to your site, prepares the paperwork and liaises with Brisbane City Council so you don’t have to.

Granny Flats Brisbane FAQs
Clear answers to the most common questions about our Brisbane granny flats.
In many cases a granny flat is considered accepted development by Brisbane City Council, meaning it can proceed without separate planning approval if it meets the criteria. A Development Application is needed if it exceeds 80m² or sits more than 20 metres from the main house. Every granny flat still needs a building permit, and we manage the approvals for you.
A granny flat generally must not exceed 80m². If it’s under 80m² and intended for household members, special council approval may not be required, though lot-size, site-coverage and setback rules still apply. We’ll design yours to make the most of what your site allows.
In many cases, yes – including to tenants outside your family, which makes a granny flat a popular way to generate rental income. Because properties with a secondary dwelling are in strong demand, it can be a smart investment. We’ll help you confirm what’s permitted for your property.
Costs depend on your design, finishes and site conditions, which is why we provide a fixed-price quote up front rather than a one-size-fits-all figure. You’ll have a clear, all-inclusive price and scope of work before any construction begins.
Once your design is approved, a granny flat can be built in as little as 12 weeks, with most projects completed within around 12 to 16 weeks. We’ll give you a clear timeline at the design stage.
Either works. A granny flat can be attached to or completely separate from the main house, as long as it stays on the same property title and meets the relevant rules. We’ll help you choose the option that best suits your block and your family.
