1. What Is a Granny Flat?
A self-contained secondary dwelling—one bedroom, bathroom, kitchen, living space—either attached or freestanding, with its own entrance. In NSW, you may build one without a full DA, under certain size and site rules.
2. How Granny Flats Help You
💰 More Income, Less Stress
Earning roughly $346/week gives a sweet annual top-up of $18K—enough to cover mortgage interest, extra bills, or even free up cash flow .
📈 Property Appreciation
Reported boosts of up to 30% in overall property value once a granny flat is installed.
👪 Family Flexibility
Ideal for aging parents, adult kids starting out, or even a work-from-home sanctuary—supporting multi-gen living with privacy.
🔒 Tax-Smart Setup
As long as you’re not running it commercially, you’re generally safe from Capital Gains Tax when creating or ending a granny flat arrangement.
