Franklin County, WA Building Safety: Building Inspections (2026)

12: the International Building Code, International Residential Code, Uniform Plumbing Code, International Mechanical Code, International Fuel Gas Code, and International Fire Code. All inspections required under the most recently adopted editions of those codes must be requested and approved before the Planning and Building Department will issue a certificate of occupancy. That covers the staged inspections typical of a construction project, such as footing, framing, and rough-in inspections, that verify the work matches the approved plans as construction proceeds. Beyond the building code inspections, the section requires other final approvals where applicable: electrical installations must be permitted and inspected by the Washington State Department of Labor and Industries, not the county, and projects served by an on-site sewage system or otherwise regulated by the Benton Franklin District Health Department need that agency's approval too.

230 folds a final inspection into the permit's life span, requiring a final inspection to be requested from the Planning and Building Department before the permit expires; if the permit lapses before that final inspection and approval, a revalidation permit at 25% of the original fee is required before any further inspections or approvals can proceed, and no more than one revalidation is allowed.
