ADU Site Preparation

ADU Site Prep Specialists

Accessory Dwelling Units are increasingly popular in Eugene, Springfield, and throughout Lane County as homeowners look to add rental income, multigenerational living space, or home offices. All Dirt, Inc specializes in the site preparation needed to make your ADU project successful. From initial excavation and foundation preparation to septic system modifications or new installations, we handle the complete groundwork so your builder can focus on construction.

Navigating ADU Requirements

Building an ADU in Oregon involves specific requirements for setbacks, utility connections, and—if not on city sewer—septic system capacity. Our team understands the local regulations in Eugene, Springfield, and Lane County and works with your builder and designer to ensure all site preparation meets code. We can assess whether your existing septic system can support an ADU or if modifications are needed, saving you time and potential headaches down the road.
