Do I need a permit for window or exterior door replacement in Unincorporated Washington County?
Unincorporated Washington County does not issue residential building permits. Washington County's own 'Important Contacts for Building' sheet (updated 8/4/2026) lists the local building inspector for the City of Springfield only and sends commercial construction to the Kentucky DHBC; the DHBC county sheet agrees. No county building permit is issued for single-family homes outside Springfield.
The requirements below come from Kentucky rules and describe the standard the work must still meet. They are not a statement that Unincorporated Washington County will issue you a permit.
It depends. Whether window or exterior door replacement needs a permit in Unincorporated Washington 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. Kentucky does not require a building permit or inspection for a single-family dwelling unless the local government has passed an ordinance creating a residential inspection program (KRS 198B.060 and 815 KAR 7:125, Section 2(2)(a)), so the first question is whether the city or county covering the address has one. The Kentucky Residential Code treats in-kind replacement of windows and storm windows as an ordinary repair; cutting a new opening or enlarging one alters the structure and is not. Sleeping-room egress openings must still meet the Kentucky Residential Code, and the state energy provisions follow the 2009 International Energy Conservation Code (KRC Chapter 11).
