Unlocking Backyard Potential: Victoria's Granny Flat Law Changes

Writer's picture: Dominique OatesDominique Oates

Victoria is on the cusp of a housing transformation with recent changes to planning laws allowing homeowners to build secondary dwellings, commonly known as granny flats, in their backyards. This shift aims to address the state’s growing housing demand and provide more affordable living solutions for families and renters alike.

Here’s a closer look at what these new regulations mean for homeowners, renters, and the broader community.



What Are Granny Flats?Granny flats, or secondary dwellings, are self-contained living units located on the same property as a primary residence. Traditionally built for extended family members, these dwellings have become increasingly popular as rental units or home offices. With the new laws, their potential uses have expanded significantly.

The Legal Changes ExplainedUnder the updated planning rules in Victoria, homeowners can now:


  • Construct a granny flat without needing a planning permit on lots of 300 square meters or more, provided there are no environmental or flooding overlays.

  • Build on a range of residential land types, provided they meet size and design criteria, such as a maximum size of 60 square meters.

  • Rent out the secondary dwelling to non-family members, creating new income opportunities for property owners.


While the planning process has been simplified, obtaining a building permit remains mandatory to ensure compliance with safety and design standards.


Why This Matters


  1. Addressing the Housing CrisisWith rental vacancies at historic lows and housing affordability under pressure, granny flats provide a practical solution. They offer more rental options without the need for large-scale developments, easing the strain on housing supply.

  2. Boosting Income for HomeownersAllowing homeowners to rent out their granny flats to tenants creates a new source of income. This is particularly valuable for retirees or families looking to offset mortgage costs.

  3. Supporting Multi-Generational LivingThese changes support families who wish to live together while maintaining independence. Whether it’s aging parents or adult children, granny flats foster closer family connections.


Opportunities for InvestorsThe updated laws present exciting opportunities for property investors in Victoria. Here’s why:


  • Affordable Entry Point: Building a granny flat is often cheaper than purchasing a new investment property.

  • Strong Rental Demand: With growing interest in smaller, affordable housing, granny flats are likely to attract consistent tenant demand.

  • Increased Property Value: Adding a secondary dwelling can enhance a property’s overall market value, making it a smart long-term investment.


Design and Compliance ConsiderationsWhile the new laws are more lenient, there are still important guidelines to follow:


  • Size Restrictions: Granny flats must typically not exceed 60 square meters.

  • Property Eligibility: The exemption applies to lots of 300 square meters or more without overlays such as environmental or flooding risks.

  • Sustainability Standards: Many councils encourage energy-efficient designs, such as solar panels and water-saving systems.


Consulting with local councils or planning professionals is essential to ensure compliance with these regulations.


How Victoria Compares to Other StatesVictoria’s move aligns with trends seen in other Australian states:


  • New South Wales: Has long allowed granny flats to be rented out, leading to widespread adoption.

  • Queensland: Offers similar flexibility, with streamlined approvals for secondary dwellings.

  • Western Australia: Encourages the use of granny flats for renters, particularly in urban areas.


Victoria’s adoption of these rules brings it in line with progressive housing policies seen across the country.


Final Thoughts


The new granny flat laws in Victoria represent a win-win for homeowners and the housing market. They empower property owners to unlock the potential of their backyards while addressing broader housing challenges.

Whether you’re a homeowner looking to generate extra income, an investor seeking innovative opportunities, or a renter in search of affordable housing, granny flats offer a flexible and practical solution.

As these laws take effect, now is the time to explore how a granny flat could fit into your property plans. The backyard revolution has begun!
