Which Window And Door Projects Trigger A Permit
For many homeowners, the permit question comes up only after they have already picked out the new windows or an entry door. In Fairfax County, simple like-for-like replacements are often treated differently from projects that change the opening size, structural framing, egress, or fire safety details.

That distinction is why homeowners asking does replacing windows require a permit in Fairfax County should not assume every project is handled the same way.

For door projects, inspectors may look at:
- The fit and operation of the new unit Any framing changes made to enlarge or relocate the opening Weather sealing and flashing details Whether the installation meets the relevant residential requirements
