Fairfax County Window Replacement Permit Exemption Rules Explained for McLean Residents

The Difference Between A Simple Replacement And A Permitted Project

For most McLean homeowners, the first question is straightforward: do you need a permit to replace windows in Fairfax County? The short answer is that a like-for-like replacement often falls under a permit exemption when the work does not change the size of the opening, the structure around it, or the window type in a way that triggers code review.

That exemption is not a blank check. If the project enlarges the rough opening, shifts the window location, changes structural members, or affects load-bearing elements, it typically becomes permit work.
