Do I need a permit for window or exterior door replacement in Unincorporated Walla Walla County?
It depends. Whether window or exterior door replacement needs a permit in Unincorporated Walla Walla County comes down to the details of your project.
Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule. New or enlarged openings, and changes to exterior walls, need a building permit; whether a same-size replacement needs one depends on the local jurisdiction's administrative rules. Replacement windows must meet the U-factor and SHGC requirements of the Washington State Energy Code whether or not a permit is required (WAC 51-11R-50300). Bedroom windows that serve as emergency escape openings must keep the required size when replaced.
