When you need additional living space for a loved one moving in with you but want to maintain privacy for yourself and your guest, an accessory dwelling unit (ADU) may be the perfect solution. You can add a new dwelling or convert an empty room or garage to make the space a home. There are several different types of ADUs, so understanding the differences between them ensures you can incorporate an ADU that is right for your needs.
Learn about the various ADU types to make better-informed decisions when creating an ADU at home.
What Is an ADU?
An accessory dwelling unit is an additional residential building or room that exists on a lot with another home, whether attached, detached or converted. ADUs are also known as accessory apartments, secondary suites and mother-in-law apartments because they provide additional accommodation for individuals on a single-family lot.
When building an ADU, understand the different types to know which would work best for your needs. Choosing the right accessory dwelling unit ensures you have plenty of living space for the people in your home, and the additional living space improves your home’s curb appeal and value.
The various types of ADUs include:
- Attached
- Detached
- Conversion
Benefits of ADUs
ADUs offer many benefits when you add one to your home. Some of the most popular advantages of designing and installing an accessory dwelling unit include:
- Increased property value
- Additional rental income
- Flexibility in living arrangements
Common Types of ADUs
You can install three types of ADUs at your home: attached, detached or conversion. Given how popular each option is, it is important to explore each type further so you can make the best decision for your dwelling.
Attached ADUs
An attached accessory dwelling unit is a separate structure that is added to the main house. It can act as an additional residential space, like a guest house, a living space for adult children or older parents, an office, a gym or a studio. When building and installing an attached ADU, you must also install a fire-rated separation between the walls of the attachment and the main house. Doing so adds more protection to both structures if a fire starts in one of them.
Additionally, attached ADUs typically have separate entrances from the main house, as if they were a townhome or apartment. A separate entrance is especially important if the attached accessory dwelling unit is used for an independent living space for your adult children or older parents.
Detached ADUs
Detached accessory dwelling units are not connected to the main house. They are often located in the backyard and stand alone as a separate unit. With detached ADUs, the individuals living in them or using them for other purposes maintain complete privacy because they have their own separate walls, utilities and yard space. You may hear detached ADUs referred to as backyard cottages.
When you construct a detached ADU, it is important to ensure it follows local building codes and zoning rules. You should also have plenty of space in your backyard to ensure the detached accessory dwelling unit is far enough away from the main house to prevent safety hazards.
Conversion ADUs
A conversion accessory dwelling unit is when you turn an existing part of your home, such as an attic, basement or garage, into a separate, functioning living space. The space you convert already exists on the property, so the unit has privacy but is still connected to your home in some way.
A conversion ADU can help you maximize your property’s space while letting your loved ones or guests have independence.
Factors to Consider When Choosing an ADU
If you want to add an ADU to your property, it is crucial to consider the following factors before starting the process. It is a significant decision, so you should make sure you are prepared by weighing:
- Property size and layout
- Zoning regulations
- Budget considerations
- Personal preferences and lifestyle
