Can I Build A Granny Flat In My Garden?

Granny flats, or “accessory dwelling units” as they are sometimes called, are small living spaces that are attached to or built into a larger home. They are often used to house an elderly relative, friend, or tenant, providing them with their own living space while at the same time keeping them close to the family. The question of whether or not these granny flats can be built in a garden is an important one, and the answer depends on a few key factors.

Local Zoning Laws

The first thing to consider when thinking about building a granny flat in your garden is local zoning laws. Many municipalities have laws that govern the building of accessory dwelling units, such as restrictions on size and placement. Making sure your proposed granny flat meets all local zoning requirements is the first step in making sure your project is legal.

Building Permits

In most cases, you will need to apply for a building permit from your local city or county government in order to build a granny flat in your garden. Depending on where you live, you may also need to get approval from a Home Owners Association or other HOA before you can begin construction.

Other Considerations

Aside from zoning and permits, there are a few other things to consider when thinking about building a granny flat in your garden. Here are some things to keep in mind:

  • Accessibility: Make sure there is easy access to the granny flat from inside the main house. This will make it easier for your elderly relative or tenant to get to their living space with minimal difficulty.
  • Amenities: Think about what amenities you would like to include in the granny flat. Are you planning on adding a kitchenette? A separate bathroom? Or just a bedroom and living space?
  • Location: Consider the location of your granny flat in relation to your main house. Where will it be installed? Will it be close enough to share utilities and other resources with the main house?


In most cases, it is possible to build a granny flat in your garden, provided you meet all local zoning laws, acquire the necessary building permits, and take into consideration the other factors listed above. Do your research to make sure your granny flat is legal and will fit in with its surroundings, and you should have no problem building the perfect space for your elderly relative or tenant.
