This program lets property owners use an accessory dwelling unit building plan that has already been reviewed by the building department and can meet building codes. The design includes an option between a shed roof or a gable roof, as well as an option between a slab or a raised foundation.
Prior to moving forward, those interested in building an ADU should contact the City's Planning Department to discuss the siting of the ADU. Setbacks, wetlands, steep slopes, or other constraints could make an ADU not feasible on some properties. A final building code review will be required.
The City of Coburg expresses its appreciation for the City of Eugene, who developed this plan and offered it to Coburg for use at no cost.
To use the City's ADU plans, follow the steps below.
- Determine the zoning of your property and if an ADU is allowed. We highly recommend contacting the City's Planning Department at megan.winner [at] coburgoregon.gov (megan[dot]winner[at]coburgoregon[dot]gov). Review Section K of Article VIII of the Coburg Zoning Code for standards specific to ADUs.
- Create a site plan that indicates the location of the proposed ADU in relation to property lines and other buildings or features on the property.
- Select one of the two available foundation styles: slab on grade or crawl space with post and beam floor system.
- Select one of the two available roof styles: gable or shed roof. If you select the gable roof, then you will need to provide a manufacturer’s truss layout and stamped truss packet. If you select the shed roof, then a layout from an I-joists manufacturer will be required. These documents are required at the time of building permit submittal.
- Apply for the required building permits through ePermitting. For questions about the permitting process and permit requirements, please contact Megan Winner, Planning Director, at megan.winner [at] coburgoregon.gov (megan[dot]winner[at]coburgoregon[dot]gov). When submitting a pre-approved plan for permits, please identify the plan as part of the pre-approved ADU program in the project description on the application.
- Once the plans are approved, you will be notified to pay permit fees. Once paid, the permit will be issued and construction can begin. When ready, inspections may be called in as each stage of construction is completed.
