- Setback requirements must be met, typically a minimum of 5 feet from rear and side property lines
- Owner-occupancy requirements may apply depending on the specific zoning designation
- All ADU projects require building permits through the City of Marysville Community Development Department
- Utility connections, including water and sewer, must comply with Marysville Public Works standards
