What Permits Are Needed for Door Replacement in Montgomery County, MD?

When A Door Swap Usually Stays Simple

For many Montgomery County homeowners, a straight door replacement is a maintenance job, not a major construction project.

The Changes That Turn A Simple Replacement Into A Regulated Project

That said, Montgomery County DPS Germantown Window Replacement can look at the exact scope, so the safest answer is always tied to the actual work plan.

Projects that commonly trigger permit review include these situations:

Changing the rough opening size or moving the header Adding French doors, sliding doors, or multi-slide patio doors where a single door used to be Any structural work around the opening Changing an exterior door that affects required emergency exit access For example, a new exterior stair, step, or stoop

The same logic applies when an older entry is being swapped for a modern unit with different hardware or dimensions. A door that looks similar on paper can still create code issues if the rough opening or exterior clearances shift.

Egress, Safety, And Access Problems That Are Easy To Miss
