Finding experienced ADU contractors in Kennewick, WA is essential to navigating the local building landscape successfully.

• Detached ADUs must comply with height restrictions aligned with Kennewick's municipal code
• Separate utility connections may be required depending on the ADU type

Types of ADUs Commonly Built in Kennewick

2. Attached ADUs – Units connected to the primary home, sharing at least one wall
3. Garage Conversions – Transforming existing garages into livable spaces
