Versatility of an Accessory Dwelling Unit

BERKELEY — An accessory dwelling unit (ADU) is a detached residential structure built on the same lot as a single-family home. Often referred to as a “granny unit,” an ADU can take a variety of forms, such as a converted garage, room addition or detached backyard structure. In 2020, new laws went into effect that made it easier for California homeowners to build ADUs on their properties.

One of the great things about an ADU is its versatility of application. Here are some common uses for an ADU:

• Multi-generational compound
• Rental property
• Office/workout room
• Guest house for visitors

Not only is there are a variety of ways to use an ADU, it’s easy to adapt your use of it as your family changes. For example, you may start out by renting out your ADU to pay off the mortgage. Later in life, if you decide you want to age in place at your current residence, you can move into the ADU and rent out your main house. That way, you get an ADA-friendly living situation (no stairs) and, since you’ve already paid off your mortgage, you’ll also generate some nice retirement income.
