In recent years, the idea of adding a Granny Flat (also known as an Accessory Dwelling Unit, or ADU) to your backyard has become increasingly popular. This type of housing unit is a secondary, self-contained living space that is typically smaller than your primary residence, built on the same lot. With their flexibility and affordability, granny flats have become an attractive option for homeowners looking to add extra space to their property, whether for personal use or as a rental opportunity.

What is a Granny Flat (ADU)?
A granny flat is a compact, self-contained dwelling that exists on the same lot as the primary residence. These units can serve various purposes, from providing extra guest accommodations to offering a private space for family members, to being used as a rental unit. While traditionally used by extended family members—hence the term “granny flat”—they have evolved to serve a range of functions.
Key Takeaways
- Increase Property Value: Adding a granny flat or ADU to your property can boost its market value by as much as 14%, offering both additional space and rental potential.
- Flexible Usage: A granny flat can be used for various purposes, such as a guest suite, home office, or long-term/short-term rental, providing versatility and adaptability for your needs.
- Additional Income Potential: Renting out your ADU can create a steady source of passive income, with the option to rent long-term or list on platforms like Airbnb for higher earnings.
- Cost-Effective Construction: Building a granny flat is generally more affordable than constructing a full-sized home, thanks to its smaller size and the use of existing land on your property.
Granny flats are often more affordable to build compared to a traditional home because they use less square footage and take advantage of the existing land on the property. This makes them an appealing option for homeowners who want to maximize the use of their property without going through the expense of constructing a full-sized house.
Benefits of Granny Flats
Here are a few benefits of adding an ADU to your backyard:
1. Increased Property Value
One of the most significant advantages of adding a granny flat is its ability to increase the overall value of your home. In fact, according to research from Zillow, homeowners who added an accessory dwelling unit (ADU) saw their property values rise 14% more than those who did not. The addition of an ADU offers more living space, which is highly valued in real estate markets where housing demand is high. Even more, if you choose to rent out the space, it can serve as a long-term investment that will generate rental income, increasing your home’s profitability.
An ADU is often considered an investment property that adds value for both present and future homeowners. Whether you rent it out long-term or use it for short-term rentals like Airbnb, a granny flat increases the appeal of your property, making it more attractive to potential buyers.
2. Additional Room or Office Space
For homeowners seeking extra living space, a granny flat can be a great solution. Many people use these units as guest suites for visiting family or friends, which is especially useful for holiday visits or special occasions. Others might use the space as an office, providing a quiet, secluded environment for work away from the main house.
The great thing about an ADU is its flexibility. You can design and use it to suit your needs, whether that means a home office, a gym, or even a hobby space. You’re not limited to just one purpose—you can adjust the layout and features to meet your changing needs over time.
3. Additional Monthly Income
One of the most appealing aspects of adding an ADU to your backyard is the potential for rental income. If your city’s zoning laws permit, you can rent out the unit to tenants, earning extra income each month. The rental rates for granny flats vary depending on their size, location, and amenities, but in high-demand areas, such as near tourist attractions or in bustling urban neighborhoods, rents can be substantial.
Another great option is listing your granny flat on platforms like Airbnb. Short-term rentals can be particularly lucrative, especially if your ADU is located in a desirable area. Having an ADU also provides you with flexibility, as you can decide whether to rent it out long-term or use it for short stays. Either way, the rental income helps to offset the costs of building and maintaining the unit.
If you are concerned about safety, don’t worry—granny flats are self-contained units, which means they can be securely locked and separate from your main residence. Renters will not have access to your primary house, offering you peace of mind while still enjoying the benefits of extra income.
4. Low-Cost Housing
ADUs are typically more affordable to build compared to traditional homes. Because these units are built on the same land as the main house, the cost of land is significantly lower. You won’t need to buy a separate plot of land, saving a lot on costs that are usually associated with building a new house. Additionally, since granny flats are smaller, construction costs are also generally lower than building a larger, full-sized house.
Granny flats also help homeowners save on landscaping costs. Since the ADU is typically placed in the backyard, there is little need for an additional yard or garden to be maintained, which saves money on landscaping and lawn care services. You’ll have more living space without incurring the added costs of managing a new garden or maintaining a large exterior.
