    Designed for one or two persons, a granny flat is a self-contained living area usually located on the grounds of a single-family home. A granny flat can be detached, or it can be attached to the other dwelling. It is sometimes called a granny flat because it is a popular way for families to accommodate aging parents.

    The granny flat is most often known as an accessory apartment or accessory dwelling unit (ADU) in the building industry. Other terms include granny pod, mother-in-law unit, in-law apartment, bonus unit, casita, carriage unit and ohana unit (primarily in Hawaii).

    Many granny flats fall into the small house category, and the surge in interest in small house living has been a boon to grandparents interested in this type of housing. In addition, Granny flats/tiny houses may be used for nannies or young adult family members. They are sometimes used as rental units, but zoning laws and deed restrictions sometimes ban renting.

    As multigenerational housing becomes more accepted, granny flats are likely to become more prevalent. As a result, realtors and builders report that they are already a good selling point.

    The upsides of having a granny flat

    Building a granny flat is an affordable way to own an investment property. If you are not yet ready to buy a separate home as an investment, you can start with constructing a granny flat first.

    A granny flat could help you make extra money by renting it out. Depending on the location of your property, your granny flat could be able to generate several hundred dollars of rental income per week, which could help cover the costs of your mortgage.

    A granny flat is easier to maintain and look after than a separate investment property, given its proximity to your primary dwelling.

    A granny flat also boosts the value of your property, especially if it is legally compliant. You would be able to sell your property at a higher value if you have a well-maintained granny flat.

    The cons of owning a granny flat

    While there are several upsides to owning a granny flat, there are also some consequences that you need to consider.

    If you decide to rent it out to unrelated parties, be prepared to deal with tenants. You need to develop patience as you might encounter tenants with different personalities.

    It would be best if you also prepare your wallets for costs associated with the maintenance of the granny flat. Related expenses do not end with the construction of the granny flat — you should also think of the changes needed to maintain and keep the property in shape.

    Another factor you should look into is the capital gains tax that you might need to settle if you sell your property down the line. For example, if you use your granny flat for income, you would be required to pay capital gains tax.

    The cost of building a granny flat varies — it depends on the quality of the build you are gunning for, as well as the purpose of the flat. Constructing a granny flat could take as little as $20,000 to as much as $200,000.

    In choosing how to set up your granny flat, there are several options you can consider. There are prefabricated and modular homes that can be installed in your backyard, but you can also build a granny flat from scratch.

    When it comes to financing the construction of your granny flat, you also have a range of choices. You can either use the equity you built in your home or apply for another loan. However, it would help if you were prepared to have your home revalued.

    You can also ask your lender if they offer loans specifically catered to the construction of granny flats. Another alternative is to refinance your existing home loan with a new credit provider.

    Like any investment property, granny flat costs depend on your needs and what you want to build. However, many experts agree granny flats prices are, on average, around $100,000 for a one-bedder.

    Here are a few reasons why granny flats are a popular option for investors:

    The rental income could provide cash flow. Many people rent granny flats, from students and young singles looking for affordable housing to retirees wanting to downsize.

    Building a granny flat is usually cheaper than buying a standalone investment property. It's also unlikely to interrupt your everyday routine, like home extensions and renovations.

    Adding a granny flat to your house could increase your resale value. In addition, it gives the new owner the option to earn rental income and the benefit of an extra bedroom.

    How is a granny flat investment taxed?

    Like any other investment property, tax is payable on the rental income you earn from your granny flat. The Capital Gains Tax liability also applies. On the flip side, granny flat tax exemptions might be available.

    If you're wondering, can you negatively gear a granny flat? Unfortunately, the answer could be yes! If the cost of your granny flat is more than your income, you could claim the loan interest and ongoing expenses (like maintenance and insurance) as tax deductions. But if your granny flat is positively geared (as in, the rental income is more than your expenses), you can only claim the ongoing costs. You might also be able to claim value depreciation, but always remember to seek professional advice.

    What makes a granny flat a great rental property

    When you decide to have your granny flat rented out to tenants, you must take note of the following:

    • Consider the safety and privacy of your tenant. The granny flat must have a separate entrance and pathways from the street to give your tenants access to the dwelling.
    • Make sure that your principal residence is located in a desirable suburb. Location is still king when it comes to granny flats — the more accessible your property is to places of interest like shopping malls, hospitals, and offices, the more profitable it will be.
    • Design your granny flat as you would your residence. Make sure that your granny flat is something you would be comfortable living in. Leave room for tenants to put their personal touches, like having the granny flat painted neutral colours.

    A granny flat should be designed to suit both your style and your budget. After all, it is a smaller version of your main home and needs to fit in and flow well with your primary dwelling.

    However, at the same time, you do need to stick to certain regulations here:

    Queensland – 80 square metres

    Although, in Brisbane, you can build a granny flat a maximum of 70 square metres but with no more than two bedrooms. So, you can try speaking directly with your local Council to find out your exact restrictions, as they do change between Councils'. See detailed QLD rules.

    Victoria – 60 square metres

    They are called a "Dependant Persons Unit" (DPU), so they must be movable. Similarly to Queensland, the regulations vary in size depending on your Council. See detailed VIC rules.

    New South Wales – From 60 square metres – 100 square metres. 

    The former is a Complying Development, and the latter must be approved by submitting a Development Application. See Detailed NSW rules.

    South Australia – 60 square metres 

    OR 70% of the total floor area of the primary dwelling (whichever is less). See detailed SA rules.

    Tasmania – 60 square metres 

    OR 30% of the total area of the main home (the lesser). See detailed TAS rules.

    Western Australia – From 70 square metres – 100 square metres depending on your local Council. Rural areas are more likely to be flexible. See detailed WA rules.

    Northern Territory 

    Metropolitan areas, such as the city of Darwin, have more strict limits, with the floor space limited to 50 square metres. But, again, rural regions are possibly more lenient. For example, your local Council may allow up to 80 square metres.

    Australian Capital Territory – 90 square metres. 

    It is worth mentioning that the ACT also has a minimum size limit for granny flats of 40 square metres. See detailed ACT rules.
