Welcome to the City of Eugene's library of pre-approved Accessory Dwelling Unit (ADU) plans. The following plans are available for purchase from the architectural companies that created them, and have been reviewed for compliance with the building code by the City of Eugene.
Steps to Building a Pre-Approved ADU
- Browse the gallery below
- Explore our growing library of pre-approved ADU plans . Review the images and details for each design to find one suitable for your needs and site.
- Select & purchase a design
- Once you choose a plan, connect with its designer through the contact information on each plan's page. The designer can guide you through the permitting process, and describe other services they offer. Pre-approved ADU plans through the City of Eugene are $500 each, and can be purchased directly from the designer.
- Prepare a site plan
- To complete permitting, you'll work with your designer to prepare a site plan showing the pre-approved structure on your site. This allows the City to review zoning, drainage, and other site-specific factors.
- Get a permit
- Submit a building permit application to City of Eugene through eBuild. By using a pre-approved plan, you'll save the cost of plan review fees because these plans are pre-approved.
