Set by local rules
Do you need a permit for Window Replacement in Columbia County?
In Washington, there is no single statewide rule for a Window Replacement; whether you need a permit is decided locally in Columbia County.
Whether a like-for-like window replacement (same size and opening) needs a permit is set locally: many jurisdictions exempt it as routine maintenance, while some require one to verify energy-code compliance. Enlarging an opening, cutting a new one, or converting a window to a door always requires a building permit. Replacement windows must meet the local energy code (U-factor and SHGC) for your climate zone, a replaced bedroom window must preserve emergency-escape (egress) clearance, and homes in historic districts usually need design review. Because Washington leaves this to local jurisdictions, the reliable answer comes from Columbia County Planning Department. Zoning setbacks apply either way.
