What Is an Accessory Dwelling Unit?
An accessory dwelling unit (ADU) is a self-contained living space located on the same property as a primary residence. These structures feature a private entrance, a complete kitchen with full-size appliances, and a usable bathroom — making them fully functional as an independent home. Informally, ADUs are often referred to as granny flats, mother-in-law suites, or garden cottages.
To qualify as an ADU, the dwelling must include:
- A bedroom or dedicated living space
- A kitchen equipped with large appliances
- A full bathroom
- A separate, lockable entrance door
ADUs are a versatile and multi-purpose solution that can serve a wide range of needs, including:
- Aging-in-place accommodations for parents or grandparents
- A private space for young adults, couples, or small families still living at home
- Housing for college students commuting locally or studying online
- A rental unit to generate additional income
- A way to increase the overall resale value of a property
ADU vs. Guest House: Understanding the Difference
An ADU offers a more practical and independent living arrangement compared to a traditional guest house or guest bedroom. While a guest house typically requires occupants to access the main home for cooking or bathroom use, an ADU provides complete self-sufficiency. Think of it as the difference between living in a condo versus sharing a home with roommates.
Because ADUs have their own kitchen and bathroom with a separate entrance, they can also be legally rented out for additional income — even if the unit was originally built for family members or close friends. This flexibility makes the detached ADU and similar structures a smart long-term investment for homeowners.
