What Is an Accessory Dwelling Unit (ADU)?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family lot. It is independent of the primary home and equipped with essential amenities.

Key characteristics of ADUs include:
- Private living, sleeping, and cooking spaces.
- Separate entrance from the main house.
- Smaller in size compared to the primary home.
ADUs are increasingly popular in urban areas like Honolulu. They help address housing shortages and promote sustainable living. Whether for family expansion or rental income, ADUs can be a smart investment.
