What is an ADU?

Accessory Dwelling Units (ADUs) are small, self-contained living spaces built on the same property as single-family homes. ADUs are also known as granny flats, in-law units, backyard homes, or secondary units. They can be attached to the primary residence or built as a standalone structure, such as a converted garage or shed. ADUs are typically smaller than the primary home and may have a separate entrance, kitchen, bathroom, and living area. They are designed to be used as a place for a family member or friend to live, as a rental property, or as a home office or studio space. ADUs allow homeowners to add additional living space to their property without building a new home.

Benefits of adding an ADU to your property

There are several benefits to adding an accessory dwelling unit to a property:

• Increase your property value: An ADU can expand the overall square footage of a property, making it more desirable to buyers.
• Extra income: An ADU can be used as a rental property, providing additional revenue for the homeowner.
• Multigenerational living: An ADU can be an excellent solution for multigenerational living, allowing family members to live on the same property while maintaining their own separate living spaces.
• Aging in place: An ADU can provide a place for an aging family member to live, allowing them to age in place while still having their own space.
• Flexible living space: An ADU can be used as a home office, studio space, or guest house, providing additional flexible living space for the homeowner.

Types of ADUs

There are several types of accessory dwelling units, each with unique features and characteristics. Here are some common types of ADUs:

• Detached ADU: These are standalone structures that are built on the same property as the primary residence. Detached ADUs can be constructed in the backyard or as a converted garage or shed.
• Attached ADU: These are ADUs that are attached to an existing home, either as a separate wing or as an addition. Attached ADUs may share walls or other common spaces with the primary residence.
• Basement ADU: These are ADUs that are located in the basement of the primary residence. Basement ADUs can be a good option if the primary residence has a large, unfinished basement that can be converted into living space.
• Garage ADU: These are ADUs that are built within an existing garage or as a converted garage. An ADU garage conversion can be a good option for homeowners who do not use their garages for parking.
• Above-garage ADUs: These are ADUs that are built above a detached garage. Above-garage ADUs can be a good option for homeowners with an oversized garage that is not fully utilized.
