Summary

In unincorporated Snohomish County, the building official runs every required construction inspection, from a preliminary site check before a permit issues through follow-up inspections during work, and can accept certified reports from approved outside agencies or individuals in place of doing the inspection directly.

City-specific rules exist: Marysville has its own building inspections rules that differ from Snohomish County's county-level regulations. If you live in Marysville, check the city-specific page instead.

The building official shall conduct all required inspections or have authority to accept reports of inspection by approved agencies or individuals. Reports of such inspections shall be in writing and be certified by an officer of an approved agency or by an approved individual. The building official is authorized to engage additional expert opinion as deemed necessary to report upon unusual technical issues that arise, subject to the approval of the director or appointing authority.
