Why 2025 Is the Perfect Year to Build a Granny Flat in Sydney

Sydney’s property market continues to evolve, and homeowners are finding creative ways to add value, boost income, and make the most of their land. One of the smartest moves this year is building a granny flat.

Recent housing pressures and high rental demand across Greater Sydney have pushed secondary dwellings into the spotlight. Whether you’re looking to create an extra income stream or house family members comfortably, a granny flat offers flexibility without the cost of moving or buying another property.

Thanks to NSW planning laws, approvals are faster than ever. Many projects now qualify for a CDC (Complying Development Certificate), cutting down approval times dramatically.

Pair this with historically strong rental yields, often 7 to 10 percent or more in key suburbs, and it’s easy to see why granny flats remain one of Sydney’s most reliable small-scale investments.
