Loudoun County Building Permit Requirements for Door Replacement Explained

When Replacing A Door Requires County Approval

When the work involves widening the rough opening, changing the header, or modifying how the door swings and latches for code compliance, a permit is commonly required.

A basic replacement, such as swapping an existing entry slab or prehung door into the same opening, may not always trigger the same level of review as a structural alteration.

French doors, larger patio doors, and conversions from a standard door to a wider unit often push the work beyond a simple replacement.

The Details That Matter To Inspectors And Review Staff
