Searching online for granny flats reveals a surprising number of companies eager to sell or build these compact dwellings. The rising popularity of granny flats can be attributed to skyrocketing house prices, a shortage of rental properties, and the increasing cost of living. Traditionally used to extend family living space or accommodate aging parents, these small homes are now also seen as affordable housing options for adult children and a means to generate passive income, further driving their demand.
A granny flat to help pay the mortgage
When Dean Roller, owner of DIY Granny Flat, decided to move to the New South Wales Central Coast a few years ago, he sought a property with a garden large enough to accommodate a granny flat to supplement his young family’s income. In 2018, he built one for $110,000.
“The decision was solely to help us pay the mortgage as we didn’t want financial stress over our heads. It’s not unusual to get $500-600 per week in rent so it can be financially viable.”
As people increasingly sought his advice on building granny flats, Dean started a blog and eventually launched his business, DIY Granny Flat. Since then, he has observed changes in the market. “More customers are coming to us because their kids can’t afford rent or save for a house deposit, and they see a granny flat in their garden as a good option,” he notes.
Planning made easier
The potential impact of granny flats on the property landscape has led state governments to revise laws related to planning, building, and renting, making it easier to add a granny flat to your property. Prior to 2023, 60 to 70% of granny flats were constructed in NSW due to more relaxed renting and building regulations. A policy introduced by the NSW government in 2009 streamlined the process, and other states have since followed suit. Between September 2022 and January 2024, Queensland, South Australia, Western Australia, and Victoria all amended laws to allow homeowners to rent granny flats to anyone, not just family members. They also eased planning and building regulations to varying degrees to facilitate the process.
“Legislation differs between states but also councils so it’s important to confirm them upfront.”
He also points out that your granny flat must comply with additional regulations, including size and placement on your property.
It’s very important to check your council’s rules on granny flats – size, conditions for privacy and other guidelines – as different councils and states have different regulations.
Maintaining privacy
Drew Healey, CommBank’s manager of retail lending in WA, offers finance tips and insights:
- Deposit Required: You can potentially borrow up to 100% of the build costs, using equity from your owner-occupied home.
- Finance Approval: As long as you meet CommBank’s lending criteria and all regulations, the bank offers quick approval times for granny flat construction.
- Portfolio Boost: Granny flats can be a profitable investment, allowing you to start or expand your investment portfolio without needing a substantial loan.
- Value Add: The cost of building a granny flat doesn’t always translate to an equivalent increase in property value. For instance, a $200,000 granny flat might not immediately add the same amount to your property’s value.
- Shop Around: “When building a granny flat, look for ways to save money and compare options. Ensure you’re not overcharged due to your location,” advises Dean.
