3 Popular Designs for Custom ADUs in 2023

Which ADU design is right for you? There are 3 popular designs you should consider: detached, attached, and ADU with a garage, each with something different to offer. Keep reading and we will break down the benefits of each ADU option.

1. Detached

Detached ADUs are backyard cottages detached from other buildings on the property. Due to detached ADUs being new construction that is separate from other structures, their quality can be higher than the existing structure, and they can be made out of different materials.

Detached ADUs allow privacy for their resident. This is great for a family member who could benefit from living on the property but still desires some level of independence and privacy. For this reason, detached ADUs are one of the more popular ADU designs, since they allow for a key ADU benefit: multi-generational accommodations.

If you have a detached building on your property that isn't in use, you can turn it into a conversion ADU, giving an old building a new life.

2. Attached

Attached ADUs are attached to another structure on the property, such as the main residence.

If your lot size is small, or if you prefer to preserve as much of your outside space as possible, an attached ADU could be the right ADU for you, since it eliminates the setback between the main house and the ADU. Essentially, they are a home addition. They can be either a one or two-story pop-out from the side of the house.

3. ADU With a Garage Underneath

Your ADU could also be two stories: the ground-floor garage, and the living space above it.

This is obviously a great idea for someone who desires their independence and wants space for their vehicle. Alternatively, the garage space could serve as additional storage space or even a makeshift gym.

For additional living space, you could have the top floor cantilever out from the garage.

The downside to these types of ADUs is that they can have higher costs than other ADU options. Also, local laws and regulations for them may be different. This makes it especially important to hire a builder with previous experience with ADU projects.

For example, if you are building in San Francisco, the city has ADU regulations and limits. A few of these city codes include a minimum of 220 square feet with a minimum of 7.5 feet ceiling height.
