Common questions
How big can an ADU be in Oregon?
In Oregon, the maximum size for an ADU is generally tied to the size of the primary dwelling and lot. Many jurisdictions allow ADUs up to 800 square feet, but specific regulations can differ. It's essential to consult local planning departments for precise measurements applicable to your property.
What are the downsides of ADUs?
Potential downsides include increased utility usage for the property, potential impacts on neighborhood character if not well-designed, and the initial investment cost. Careful planning and design can mitigate these concerns. We focus on creating ADUs that enhance, not detract from, your property.
