What Is a Granny Flat and How Is It Different From an ADU?

A granny flat is a self-contained living space built on the same lot as a primary residence and often intended for housing family members, such as aging parents.  A term often used interchangeably with accessory dwelling units (ADUs), granny flats are traditionally designed with multigenerational living in mind and may offer more accessible layouts or additional storage for convenience. Granny flats provide privacy and independence while being close to the main home, making them a great solution for housing family or providing a rental unit.

Is a Pre-Approved Plan Right for You?

Pre-approved ADU plans offer several advantages:

• Faster Permitting: These plans meet local codes and are pre-reviewed, cutting down on approval times.
• Lower Costs: Skip custom design fees with pre-designed layouts tailored to local requirements.
• Simplified Process: Pre-approved plans estimate much of the uncertainty in the design and permitting stages.

They are a great option for homeowners who want to fast-track the design & permitting process and reduce costs. However, it is important to note that pre-approved plans cannot be customized. They are fixed designs intended to simplify and expedite the process, but they do not allow for adjustments such as reconfiguring rooms, resizing, or adding custom features.

If you’re looking for more flexibility, this layout can be tailored as a semi-custom ADU plan. Read more about customization paths in our Custom ADU Guide.
