Submittal notes
These apply at Snohomish County County level — verify city-specific items directly with Woodway Permits.
- Everett: Everett requires cross-sections and framing plans to explicitly show whole-house ventilation duct routing, exhaust outlet locations, and crawl space ventilation calculations — R406 energy credit text must also appear on the architectural drawings, not only on the prescriptive worksheet.
- Snohomish County: Snohomish County: Native Growth Protection Area (NGPA) boundaries must be marked on site plans alongside WSEC-R calculations.
