Why Preliminary ADU Plans Are Essential
Preliminary ADU plans act as the blueprint for your project. They clearly show:
- Zoning compliance and setback limits
- Floor layouts, doors, and window placement
- Exterior elevations and building sections
- Structural relationships between your ADU and the main house
Having detailed preliminary ADU plans Portland ensures your project meets the city’s requirements for safety, design, and usability, while minimizing surprises during construction.
