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

The First Question To Ask Before Replacing A Door

The Changes That Turn A Simple Replacement Into A Regulated Project

That said, Montgomery County DPS 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:

• Replacing a door and enlarging or shrinking the opening
• 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
• Adding electrical, masonry, or landing work tied to the new door

Why Inspections Are Often About The Opening, Not Just The Door

This is where egress, landing height, and clear opening dimensions come into play.

If a basement entry is being altered, or if the same project includes a sleeping room or finished lower level, the opening may need to meet egress standards.

For basement and lower-level projects, county reviewers may look at:

• Especially for finished spaces used as sleeping rooms
• Whether the landing and stairs meet basic safety requirements
• This is common when converting an existing utility entrance
• Whether any wall changes affect the structural opening

The county may not care that the product is efficient, but it may care if the installation changes the opening or requires a new inspection point.

What To Confirm Before The Installation Date

That matters because the answer affects lead times, inspection timing, and whether drawings are needed.

Before work starts, confirm these points:

1. If not, a permit is more likely.
2. Exterior and egress-related work gets more scrutiny.
3. Those details often trigger review.
4. Does the HOA or historic district need approval first?
5. Do not assume.
