The main difference between a home addition and a JADU (Junior Accessory Dwelling Unit) lies in their purpose and legal definition. A standard addition expands your existing living space, such as adding a bedroom or family room, and remains part of your primary residence. In contrast, a JADU is a separate, self-contained unit created within the walls of a single-family home, typically under 500 square feet, with its own kitchen and bathroom. It must share a bathroom or entrance with the main house in many cases. For a thorough breakdown of requirements, zoning rules, and design considerations, please review our internal article titled Room Addition / ADU (JADU). At Golden Shore Design and Build, we guide homeowners through both options to match their property goals.
