Granny Flat Approvals in Rockingham

Granny flats in Rockingham are generally permitted under the City of Rockingham’s local planning scheme, but they must meet specific requirements to gain approval.



In most residential zones, ancillary dwellings are allowed where they comply with key criteria such as maximum floor area (typically up to 70sqm), setbacks, and overall site coverage. The granny flat must remain secondary to the main dwelling and cannot be subdivided or sold separately.


Approval pathways can vary depending on the zoning of the property and whether the design meets deemed-to-comply provisions. In many cases, a compliant design can be approved through a streamlined process, while more complex builds may require additional planning and assessment.

Factors like block size, existing dwelling placement, and access will all influence what can be built on your property. Working with a builder who understands Rockingham’s local council requirements can help ensure the design meets all criteria from the outset and avoids unnecessary delays.

Why Granny Flats Work So Well in Rockingham

Rockingham is a well-established coastal region south of Perth, known for its beachside lifestyle, family-friendly suburbs, and ongoing residential growth. This makes it an ideal location for granny flats, especially for homeowners looking to create flexible living spaces or generate additional income.


The City of Rockingham includes suburbs such as Rockingham, Baldivis, Secret Harbour, Warnbro, Safety Bay, Waikiki, Port Kennedy, Cooloongup, Hillman, Shoalwater and Golden Bay. Many of these areas feature larger residential blocks and established homes, which are well-suited to secondary dwellings.


The area is well connected via the Kwinana Freeway, Patterson Road, Ennis Avenue and the Mandurah railway line, making it accessible for commuters travelling to Perth.


The City of Rockingham had approximately 133,000 residents and over 50,000 dwellings, supporting a strong homeowner base and consistent demand for practical housing solutions like granny flats.

Talk to our team about your block, your goals, and the type of granny flat you want to build in Rockingham. We will give you clear advice, outline your next steps, and make it easy to get started.

Frequently Asked Questions

  • Can I build a granny flat on a small block in Rockingham?

    Yes, it may still be possible. The old 350sqm minimum lot size rule in WA was removed for compliant ancillary dwellings, but the design must still meet key requirements such as setbacks, site cover, height, privacy, and access.

  • What size can a granny flat be in Rockingham?

    In most cases, a compliant granny flat can be up to 70 sqm under current WA rules. The right size and layout for your project will still depend on your block, site access, and how you plan to use the space.

  • Do I need council approval or a building permit in Rockingham?

    You may not need planning approval if your granny flat meets the deemed-to-comply requirements. However, a building permit is still required before construction begins, so it is important to get the right advice early.

  • Can I rent out a granny flat in Rockingham?

    Yes, often you can. Under the current WA ancillary dwelling rules, a compliant granny flat can be used by a family member, a friend, or a tenant under a rental agreement.

  • Does a granny flat need extra parking?

    Not always. Most ancillary dwellings do not require an extra parking bay, although some exceptions can apply depending on the density of the area and the specific needs of the property.

  • Which Rockingham suburbs should this page mention?

    It should mention key service areas that local homeowners are likely to search for. This can include Rockingham, Baldivis, Safety Bay, Shoalwater, Waikiki, Warnbro, Port Kennedy, Secret Harbour, Golden Bay, Singleton, Cooloongup, Hillman, and Karnup.

  • How long does a granny flat take to build?

    Build times can vary based on the design, approvals, construction method, and any required site works. It is better to give clients a realistic timeline based on their property rather than making a promise that may not suit every project.

  • Can the design match the existing house?

    Yes, absolutely. A granny flat in Rockingham can be designed to look more consistent with the main home by selecting similar colours, roof lines, materials, and finishes across the property.

  • Is a granny flat a viable option for multigenerational living in Rockingham?

    For many families, yes. A granny flat can create a more private and flexible space for parents, adult children, or guests, while still keeping everyone close and offering rental flexibility where permitted.

  • What should I prepare before asking for a quote?

    It helps to have a few basic details ready before you get in touch. The site address, a few photos, rough block details, your intended use, and a shortlist of must-haves can make the first conversation much more useful.
