Understanding ADUs

What is an Accessory Dwelling Unit?

An Accessory Dwelling Unit (ADU) is a secondary residential unit located on the same lot as a primary single-family home. ADUs can be either attached or detached and are designed to offer fully independent living facilities, including areas for sleeping, cooking, and sanitation.

Different ADU Structures Explained

There are several types of ADUs that can be developed based on space and property layout:

  • Detached ADU A stand-alone structure separate from the main house.
  • Attached ADU Physically connected to the main residence via at least one shared wall.
  • Converted ADU Created by converting part of the existing home or an accessory structure (e.g., garage, pool house).
  • Junior ADU (JADU) A smaller unit created within the existing footprint of the main home, often with shared sanitation facilities.
