ADU Construction · Hood River County, Oregon
Permit required
In Oregon, a ADU Construction requires a building permit.
An accessory dwelling unit (ADU) always requires a building permit because it adds a habitable dwelling, including electrical, plumbing, mechanical permits and egress/zoning review. Plans are reviewed under the Statewide code (IRC 2021); apply through Hood River County Building Department before work begins.

Building an Accessory Dwelling Unit requires complex zoning, structural, and utility permits.
With a population of around 23,905 residents, Hood River County generally runs a more streamlined permitting process than major urban hubs.
Code Compliance & Inspections
Under Oregon seismic provisions, structural plans are reviewed for retrofitting and shear-wall integrity to comply with the Oregon Structural Specialty Code.
Local Zoning & Setbacks in Hood River County
Regardless of the state permit rule above, Hood River County still enforces property-line setbacks and local zoning for your ADU Construction. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Hood River County Building Department before building.
Zoning & Cost Factors
Oregon is famous for its statewide land-use planning program, which legally mandates "Urban Growth Boundaries" to prevent sprawl and protect farm and forest lands. Fortunately, Oregon maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What happens if I build a ADU Construction without a permit in Hood River County?

Yes. Oregon generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Oregon Structural Specialty Code.
