What Is an Accessory Dwelling Unit?

An ADU is essentially an apartment extension on the same property with your primary dwelling, but generally smaller than your main dwelling. These may be designed as:

  • Detached Units: a standalone building, often known as backyard cottages, separated from the house.
     
  • Garage Conversions: Repurposing an area into a cozy living space.
  • Attached Units:  extension to your own home for easy access.
  • Basement Apartments: otherwise underutilized spaces into a complete suite.

Why Build an ADU?

ADUs are amazingly flexible and can be adapted to many purposes. Some of these include:

  • Multigenerational Living: Namely, provide a safe, independent place for aging parents or adult children.

  • Rental Income: Make a steady income source from tenants renting this particular space.

  • Guest Accommodation: If your friends and relatives stay over, it can be a private and comfortable place to stay.

  • Home Office or Studio: This space can be turned into a peaceful, distraction-free work area.
