Granny Flats Step-by-Step Guide: Council Approval Status

So, you’re mulling over the idea of adding a second dwelling or a granny flat to your property?

That’s fantastic news! These versatile structures can be a game-changer for your property’s functionality and even your finances, offering a cozy, private spot for family, guests, or a valuable source of rental income.

But here’s the deal: before you dive into the exciting world of granny flats, you need to navigate the often tricky path of council approval. It might seem like a daunting task, but fear not! In this friendly, casual, and helpful guide, we’re going to break down the process into bite-sized, easy-to-follow steps.

Frequently Asked Questions (FAQ’S)

Navigating the world of granny flats and council approvals can bring up a lot of questions. Here are some of the most common queries we encounter, providing you with quick, clear answers to get you started on your journey.

What is a Granny Flat?

A granny flat is a self-contained, secondary dwelling located on the same property as a primary home. Typically situated in the backyard, these compact and versatile structures offer a private living space. They are often used to accommodate family members (like aging parents or adult children), provide a comfortable spot for guests, or serve as a source of rental income, offering a cost-effective solution for adding extra living space without a full home renovation.

Do I need council approval for a granny flat in Queensland?

Yes, in almost all cases across Queensland and Australia, you will need council approval to build a granny flat. While specific regulations vary by local council, granny flats are considered a ‘secondary dwelling’ and must comply with zoning laws, building codes, and environmental standards, see here. Even if your property is zoned appropriately, a development application or similar approval process is typically required to ensure compliance and safety.

What about the other states in Australia?

While the need for some form of approval is virtually universal across Australia, the specific processes and terminology for granny flats vary significantly from state to state.

Here are official government resources where you can find more information for each state and territory:

• • New South Wales (NSW): NSW often features a streamlined ‘Complying Development Certificate (CDC)’ process for eligible granny flats, allowing them to bypass a full Development Application (DA) if specific criteria are met.

    • See NSW policy and legislation here: NSW Department of Planning and Environment – Secondary Dwellings (Granny Flats)

     

  • Victoria (VIC): Traditionally refers to them as ‘Dependent Persons Units’ (DPUs), often with occupancy restrictions, although recent reforms are easing some rules. A building permit is always required, and a planning permit may be needed depending on the granny flat’s size and specific location.

    • See VIC policy and legislation here: Victorian Department of Transport and Planning – Dependent Person’s Units (DPU)

     

  • Western Australia (WA): As of April 2024, many granny flats are simplified, often exempting them from council planning approval if they meet specific ‘deemed-to-comply’ requirements. However, a building permit is always required.

    • See WA policy and legislation here: Department of Planning, Lands and Heritage – Ancillary dwellings (granny flats)

     

  • South Australia (SA): SA has implemented reforms to make granny flats more accessible, increasing their maximum floor area and allowing them to be fully self-contained and rented out to non-family members. They still require assessment and building rules consent.

    • See SA policy and legislation here: PlanSA – Planning and Design Code (Search for ‘Ancillary Accommodation’)

     

  • Tasmania (TAS): Tasmania’s regulations for secondary dwellings are managed under the Tasmanian Planning Scheme. These structures are typically limited in size (e.g., often not more than 60m²) and must share services with the main residence. Building approval is always required, with specific rules varying between local councils.

    • See TAS planning information here: Planning in Tasmania – Housing

     

  • Northern Territory (NT): The NT Planning Scheme governs land use and development, including what are often called ‘independent units’ or ‘secondary dwellings’. While a building permit is always needed, recent amendments have increased maximum floor area limits, though a development permit may also be required.

    • • See NT building permit information here: NT.GOV.AU – Getting a building permit

     

  • Australian Capital Territory (ACT): In the ACT, ‘secondary residences’ or ‘independent units’ require both Development Approval and Building Approval. Recent reforms (as of May 2025) are removing the 120sqm limit for secondary dwellings in some residential zones to encourage more housing options.

Your Step-by-Step Guide to Granny Flat Council Approval

Navigating council approval for your granny flat might seem complex, but with a clear roadmap, it becomes a manageable process. Our 20+ years of experience in the Australian portable and modular building industry has distilled this journey into practical, easy-to-follow steps designed to ensure a smooth approval.

Step 1: Research Local Regulations

Understanding the foundational rules in your specific area is the critical first move. Regulations for granny flats vary significantly across Australian states and even between local councils. Don’t skip this groundwork – it lays the entire foundation for a compliant project.

• Check Your Local Council’s Rules Begin by thoroughly exploring your local council’s official website. Look for their planning scheme, zoning maps, and specific policies or guidelines concerning secondary dwellings, ancillary accommodation, or granny flats. Note down key definitions, permissible uses, and any unique local requirements.
• Understand Zoning Requirements Your property’s zoning designation is paramount. It dictates whether a granny flat is allowed in your area and, if so, what type. Verify your property’s zoning classification, as this information is usually available on council websites and directly impacts your project’s viability.
• Identify Key Restrictions Be vigilant for any specific restrictions outlined in the local planning instruments. These often include maximum size limits, minimum lot sizes, essential setback requirements (distances from boundaries), and even design guidelines. Knowing these upfront will shape your design choices and prevent future roadblocks.
• Initial Council Consultation Don’t hesitate to engage with your local council’s planning department early on. A brief phone call or email can clarify initial doubts about zoning, general requirements, and the specific application pathway for your property. This proactive step can provide invaluable insights tailored to your location.

Step 2: Strategic Site Selection & Design

Once you grasp the regulatory landscape, the next phase involves choosing the ideal spot on your property and designing a granny flat that aligns with both your vision and all applicable rules. This blend of practicality and compliance is key.

• Choose the Ideal Location Carefully select the exact placement of your granny flat on your property. Consider factors such as accessibility for residents and services, ensuring privacy for both dwellings, and how the new structure integrates seamlessly into your existing outdoor space and overall property layout.
• Verify Placement Compliance With your ideal location in mind, rigorously check that it adheres to all regulatory requirements identified in Step 1. This includes confirming compliance with setback rules (front, side, and rear boundaries), overshadowing limits, and any other site-specific placement criteria.
• Consult Design Professionals Engaging a professional designer or architect at this stage is highly recommended. Their expertise ensures your granny flat not only meets your aesthetic and functional needs but also fully complies with all local regulations, building codes, and accessibility standards, avoiding costly redesigns later.

Step 3: Prepare Your Documentation

This phase is about translating your design into a comprehensive package of information that your council needs for assessment. Meticulous preparation of your application documents is crucial for a smooth and efficient approval process.

• Gather All Required Documents Begin by compiling a checklist of every document your local council specifically requests for a secondary dwelling application. This typically includes detailed architectural plans, site surveys, engineering reports, and potentially bushfire or flood hazard assessments.
• Create Detailed Plans Your plans are the blueprint of your project. They must be comprehensive and clear, typically comprising precise floor plans with dimensions, external elevations of all facades, and a detailed site plan indicating the granny flat’s exact position relative to boundaries, existing structures, and services.
• Engage a Surveyor (If Needed) Depending on your council’s specific requirements, a licensed surveyor may need to conduct a formal site survey. This survey accurately maps your property boundaries, existing structures, and critical levels, ensuring your proposed granny flat aligns perfectly with property setbacks and site conditions.
• Assemble Your Application Kit Organize all gathered documents, plans, and reports into a complete and coherent application package. Missing or incomplete information is a primary cause of delays, so ensure every piece is present, clearly labelled, and correctly formatted as per council guidelines.
• Review & Refine Your Plans Before submission, meticulously review every detail of your plans and supporting documentation. Verify accuracy, consistency, and absolute compliance with all local regulations. A thorough internal check at this stage can prevent future queries or requests for further information from the council.
• Seek Expert Assistance If the complexity of preparing documentation seems daunting, consider leveraging professional assistance. Architects, experienced building designers, or planning consultants who specialise in granny flat projects can expertly manage this phase, ensuring all plans meet stringent council and building code requirements.

Step 4: Submit Your Application

Once your documentation is meticulously prepared and reviewed, this step is about formally submitting your application to the relevant council authority. It’s a straightforward action that initiates the official assessment period.

• Formal Application Submission With all documents in order, submit your complete application package to your local council. This can often be done online via their planning portal, in person at the council offices, or by mail, depending on their accepted methods. Ensure you receive an application reference number.
• Understand Processing Timelines Be aware that once submitted, your application will undergo a thorough review by council staff. Processing times vary significantly between councils and project complexity, typically ranging from 6 to 12 weeks, but it’s essential to factor this review period into your overall project timeline.

Step 5: Navigate the Approval Process

After submission, your application enters the council’s assessment phase. This step involves responding to council feedback, addressing potential challenges, and maintaining proactive communication to guide your project smoothly towards approval.

• Understand the Review Process Once lodged, your application will be rigorously assessed against local planning schemes, building codes, and environmental standards. Council officers will check for compliance with setbacks, height limits, privacy impacts, and appropriate infrastructure connections.
• Anticipate & Address Challenges Be prepared for potential challenges during the review. These might include requests for additional information, neighbour objections regarding visual impact or privacy, or specific concerns about parking and access. Proactively addressing these ensures smoother progression.
• Maintain Responsive Communication If the council issues any Requests for Further Information (RFIs) or has questions, respond promptly and thoroughly. Clear, concise, and timely communication with council officials demonstrates professionalism and helps to keep your application moving forward without unnecessary delays.
• Seek Planner/Architect Support Should you encounter unexpected roadblocks or complex issues, engaging a town planner or architect experienced in granny flat projects can be highly beneficial. Their expertise can help navigate technical planning complexities, mediate disputes, and formulate effective responses to council concerns.
• Attend Required Meetings Depending on your council’s procedures or if significant issues arise, you might be required to attend council meetings or hearings concerning your application. Be prepared to succinctly present your case and respond to any questions or objections from council members or neighbours.
• Keep Meticulous Records Throughout the entire approval process, maintain comprehensive records of all correspondence with the council. This includes emails, letters, submitted documents, and detailed notes from phone calls or meetings. This documentation is invaluable for reference or in case any disputes arise.
• Practice Patience Council approval processes can sometimes be lengthy and unpredictable. It’s not uncommon to experience delays. Maintaining patience and persistence, while remaining proactive in your communication, is crucial for successfully achieving your granny flat dreams.
