Doorway Widening in Knoxville, TN

This page is about the doorway: how the clear opening is measured, why the two published bands differ so widely, what decides which one a house needs, and the lines a quote has to separate. Every figure here is a published United States range from the 2026 guides named at the foot of the page, not a Knoxville price. We are a free matching service, not a building company: we introduce you to licensed accessibility contractors, and whether a wall carries load is a question for the contractor and whoever reviews the structure.

What doorway widening is, and who it is for

Widening a doorway means increasing the clear opening - the gap a person actually passes through with the door open - rather than the size the door is sold as. A 30-inch door commonly leaves around 28 inches of clear opening once the door leaf and its stop are counted, which is a tight fit for a walker and not passable for most wheelchairs.

The work ranges from a trim swap to a structural opening. At the small end the casing comes off, a wider door and frame go in, and the trim is made good. At the large end the opening is cut wider, the wall is reframed, a header goes in over the opening, wiring or plumbing inside the wall is moved, and the wall is rebuilt and finished.

It comes up most often on the bathroom door, the bedroom door on the ground floor, and any doorway on the route between them.

The two published bands, and which one your doorway is

Published 2026 figures describe two different jobs, and the honest answer to what it costs is that it depends on which one is in front of you.

$600 - $2,000 typical for wheelchair access. That is the published band for widening a doorway for wheelchair access, and it describes the case where the opening can be made bigger without touching the wall structure: the trim off, a wider door and frame in, and the finish made good. A two-inch gain from trims and a new door sits at this end of the range.

$701 - $8,056, averaging about $4,378. That is the normal range and average for disability-accommodation work published in the 2026 data named on this page, and it describes the structural case: the opening cut wider, the wall reframed, a header added, whatever is inside the wall moved, and the whole thing rebuilt and refinished.

What decides which case it is

Whether the wall carries load. A load-bearing wall needs a header over the new opening, and that is designed rather than improvised. This is the largest single factor and the reason the published range is so wide.

How many inches the opening has to gain. A small gain can sometimes come from the trim, the door stop and a thinner door rather than from the framing.

What is inside the wall. Wiring, a switch or a socket at the edge of the opening, and plumbing that has to be rerouted each add work.

The finish, and the floor transition at the threshold, which matters as much as the width if a chair or a walker has to cross it without catching.

Whether the door goes back. A pocket door or an outward-swinging door changes the carpentry and the wall work again, and sometimes removes the need for more clear width.

What a doorway quote must itemise

Two doorway quotes are only comparable if both say which case they are. Ask for these as separate lines:

• Which case it is priced as: a trim-and-door change or a structural opening.
• The clear opening now, the clear opening proposed, and how both were measured.
• Whether the wall carries load, and who confirms that.
• The framing and the header, as their own lines rather than part of a lump sum.
• The door, frame and hardware - reused, replaced, or changed to a pocket or outward-swinging door.
• Moving wiring, a switch, a socket or plumbing inside the wall.
• Making good: drywall, tile, trim, paint, and the floor transition at the threshold.
• Subfloor or floor structure at the opening, if the floor has to be patched.
• The permit fee and who pulls the permit.
• Removal and disposal of the old door, the casing and the debris.
• The workmanship warranty on the opening.

Questions to ask the contractor

Ask these before the wall is opened:

• Is this a trim-and-door job or a structural opening, and what would each one cost?
• What is the clear opening now, and what will it be afterwards?
• Does this wall carry load, who confirms it, and will a drawing be needed?
• What is inside the wall that has to move - wiring, a switch, plumbing?
• How will the threshold be finished so a chair or a walker crosses it without catching?
• Does the work need a permit in Knox County, and does the community need to approve it separately?
• Who makes good the wall and the paint, and is that inside this price?
• What is the sequence, and will the doorway be out of use while it is done?

Permits and how the matching works

In Knox County, work that cuts a structural opening or adds a header can need a building permit, and the fee is charged by the county or the city rather than by the contractor. A community with architectural review can want approval of its own, particularly where the doorway is visible from outside. The contractor and the authority having jurisdiction decide what applies at an address, not this site.

Tell us which doorway is the problem - a bathroom door a walker will not pass, a 28-inch opening on the route to the bedroom, a door that cannot be closed once a chair is in the house - and which part of the county you are in: Knoxville, Farragut, West Knoxville, Powell, Karns, Fountain City, Bearden, Halls, Maryville, Alcoa, Clinton, Oak Ridge, Lenoir City and Sevierville.

We introduce you to licensed accessibility contractors whose crews work that area, at no charge. The measurement, the scope and the priced quote come from the contractor you are introduced to.
