GRANTS PASS – The City of Grants Pass Community Development Department has developed pre-approved building plans for the construction of accessory dwelling units (ADUs) within the city. Full plans, truss calculations, and building permit applications are now accessible at the city’s website: https://www.grantspassoregon.gov/1396/Accessory-Dwelling-Unit-ADU-Building-Plans.
Applicants wishing to add ADUs to their property can submit for a building permit by providing the Community Development Department with three complete sets of to-scale building plans printed at 24 x 36 inches, three copies of a to-scale site plan, and a completed and signed application.
If the proposed site property is located within a hazard area such as a flood or steep slope, additional requirements may apply. Development in Special Flood Hazard Areas requires additional city permits.
