Pre-Approved ADU Plans Library

Steps to Building a Pre-Approved ADU

1. Browse the gallery
   • 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.
2. 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.
3. 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.
4. 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.
5. Pre-Approved ADU due diligence checklist
   • Do your due diligence and be well-informed about your property. 
6. NOTE: In certain scenarios depending on specific site conditions such as steep slopes or certain soil types or if choosing a 2-story design or a design that features a tall structural wall, additional engineering calculations will need to be included in the final building permit submittal. Please work with the architect and a structural engineer on providing required structural calculations.
