Many Perth homeowners are interested in expanding the liveable space on their block, and so called ‘granny flats’ have become a convenient solution.
Also known as ancillary dwelling units or secondary suites, these self-contained living spaces offer homeowners a range of benefits.
If you’re wondering whether you can put a granny flat on your property, it is first crucial to understand the regulations and considerations involved. We have heard all your questions and are here to answer them.
What is a Granny Flat?
A granny flat is a self-contained structure typically built on the same property as a single-family home. These units usually include a bedroom, bathroom, kitchen, and living area, providing a separate and private living space.
Granny flats are a great solution if you want to accommodate your ageing parents, adult children or guests, or simply rent them for additional income.
They can also be used as a home office, separate entertaining area, rumpus room or creative workshop. Granny flats are no longer just for granny.

Regulations and Zoning Laws
In Western Australia, recent changes to the Residential Design Codes (R-Codes) have made it easier to add granny flats to properties. Here are some key points:
- Planning Approval: You no longer need planning approval for granny flats if they are up to 70 square metres in size on residentially zoned land. This simplifies the process significantly.
- Lot Size Requirements: The previous minimum lot size requirement of 350 square meters has been removed, allowing more flexibility in the types of properties that can accommodate a granny flat.
- Design Compatibility: Granny flats are no longer required to be compatible with the design of the existing dwelling, giving homeowners more creative freedom. However, bear in mind that a quality-constructed granny flat that is designed to compliment the main home is going to add far greater value to the property than the cheaper demountable-style products that are commonly available will.
- Building Permit: Although planning approval isn’t needed for compliant granny flats, you still need to obtain a building permit from your local council to ensure that construction meets safety standards and building codes.
- Rental Options: The amendments also allow homeowners to rent out granny flats to non-family members, offering a potential source of income.
These changes aim to boost housing supply and provide more flexible living arrangements for families and investors in Perth and throughout Western Australia.
Consult with your local council and a professional builder experienced in granny flat construction for help navigating these regulations and ensuring stress-free construction.

A professional assessment can help determine if your property meets the requirements for a granny flat.

A granny flat can be a valuable addition to your property, enhancing its functionality and versatility.

We added a freestanding granny flat for the adult daughter of a Menora family, that perfectly matches the existing character home for the Menora granny flat project. This charming flat includes two bedrooms, a bathroom, a kitchenette, a meal area, and a living room.
