How Much Does It Cost to Widen a Doorway for Wheelchair Access? What Knoxville Homeowners Should Know

If a wheelchair, power chair, or walker barely fits through a doorway, or does not fit at all, widening the opening can make a significant difference in how safely and independently someone moves through the home.

But one of the first questions Knoxville homeowners understandably ask is: How much does it cost to widen a doorway for wheelchair access?

There is no single price that applies to every home. National estimates vary widely because widening a simple interior doorway can be very different from altering a load-bearing wall, relocating electrical wiring, replacing an exterior door, or matching detailed trim in an older home.

As a general reference, Angi reports that doorway-widening projects can range from approximately $50 to $3,000 nationally, with an average around $1,200, depending on the work involved. That range is useful for understanding the variables, but it should not be treated as a quote for a specific Knoxville home. The actual cost depends on the doorway, wall construction, desired width, finishes, and any structural or mechanical work required.

For homeowners planning to age in place, the more important question is often not simply how much does it cost, but which doorways actually need to be widened to make the home functional and safe.

How Wide Should a Doorway Be for Wheelchair Access?

A wheelchair-accessible doorway needs enough clear opening width for the person and their mobility device to pass through safely.

The 2010 ADA Standards for Accessible Design specify a minimum clear opening of 32 inches for accessible doorways, measured with a swinging door open 90 degrees from the face of the door to the opposite stop. Openings that are more than 24 inches deep require additional width under ADA standards.

For a private residence, ADA requirements do not automatically apply in the same way they do to many public and commercial spaces. However, the measurements provide a useful accessibility benchmark when planning a home modification.

It is also important to understand the difference between the size of the door itself and the clear opening available when the door is open. A nominal 32-inch door, for example, does not necessarily provide a full 32 inches of usable clear space because the door, hinges, frame, and stops reduce the opening.

The right doorway width should ultimately be based on:

• The wheelchair, walker, or mobility device being used

• Whether the person approaches the doorway straight on or must turn

• Available maneuvering space on either side

• The person's ability to control the mobility device

• Whether a caregiver also needs space to assist

• Future mobility needs

This is why simply measuring a wheelchair and adding a few inches is not always enough.

How Much Does Doorway Widening Cost?

The cost to widen a doorway for wheelchair access can vary substantially from one project to another.

A relatively straightforward interior doorway in a non-load-bearing wall may require less work than an exterior entrance or a doorway located in a wall containing plumbing, electrical wiring, ductwork, or structural framing.

Some of the biggest factors affecting cost include:

1. Whether the Wall Is Load-Bearing

One of the first things a contractor needs to determine is whether the doorway is located within a load-bearing wall.

A non-load-bearing wall may be relatively straightforward to modify. A load-bearing wall can require a larger structural header and additional framing to safely redistribute the weight above the opening.

That additional labor and material can increase the overall project cost.

This is also one of the reasons doorway widening should not automatically be treated as a simple DIY project. Removing framing without understanding the structure of the home can create much larger problems.

2. Electrical Wiring, Plumbing, or HVAC Inside the Wall

Walls often contain more than framing.

Electrical outlets, switches, wiring, plumbing pipes, or HVAC components may be located directly beside a doorway. If widening the opening interferes with any of these systems, they may need to be relocated.

That can increase both the labor involved and the number of trades required to complete the project properly.

An evaluation before construction begins can help identify these issues and create a more realistic scope of work.

3. Interior vs. Exterior Doorways

Widening an interior bedroom doorway is generally different from widening the main entrance to a home.

An exterior doorway may involve:

• Weatherproofing

• Siding or exterior finishes

• Threshold modifications

• New exterior trim

• Security hardware

• Insulation

• A new door

• Changes to a porch, landing, or ramp

• Additional structural considerations

The doorway itself also needs to work with the surrounding entrance.

For example, creating a wider front door does not solve the accessibility problem if a wheelchair user still has to navigate several steps immediately outside it.

Knoxville Aging in Place evaluates these issues together through its Entry & Exit Accessibility Solutions, which include widened doorways, ramps, platform lifts, automatic door openers, lever handles, lighting, and other improvements that can make getting into and out of the home easier.

4. The Amount of Widening Required

There is a major difference between gaining an additional inch or two of clear space and substantially rebuilding the opening.

Sometimes the existing framing provides enough room for a relatively minor modification. In other situations, the entire rough opening must be enlarged.

The correct approach depends on both the existing doorway and the mobility device being accommodated.

This is why measuring the actual clear opening is an important starting point.

5. Door Type and Hardware

The door itself contributes to the total cost.

A project may require:

• A wider hinged door

• A pocket door

• Different hinges

• Swing-clear hinges

• Lever-style handles

• An automatic door opener

• New locks or security hardware

• Threshold modifications

In some situations, specialized hardware may improve usable clearance without requiring as extensive a structural change. In others, widening the opening is the more practical long-term solution.

The best option depends on the person using the doorway and the surrounding space.

6. Drywall, Trim, Paint, and Finishing Work

Doorway widening is not finished when the framing work is complete.

Drywall may need to be repaired. Trim needs to be replaced or matched. Walls may require painting. Flooring or baseboards near the doorway may also be affected.

These details can be especially important in older Knoxville homes where the existing trim may not be readily available.

A properly completed accessibility modification should not look like an afterthought.

Whenever possible, the finished doorway should function better while still fitting naturally with the rest of the home.

Do You Need to Widen Every Doorway in the House?

Usually, no.

One of the most important parts of planning accessibility modifications is identifying which routes through the home actually need to accommodate a wheelchair, walker, or other mobility device.

For many homeowners, the priority is creating an accessible path between the spaces used every day.

That may include:

• The main entrance

• Bedroom

• Bathroom

• Kitchen

• Primary living area

• Essential hallways

A closet doorway that is rarely used, for example, may not be nearly as important as the bathroom doorway someone needs to pass through several times every day.

This is where a whole-home accessibility plan can help control costs. Rather than automatically modifying every doorway, the goal should be to create a safe and practical route through the home based on how the individual actually lives.

A Home Assessment Consultation can help identify accessibility barriers, prioritize modifications, and determine which changes may be needed now versus those that can be planned for later.

Bathroom Doorways Often Deserve Special Attention

The bathroom is one area where doorway width can become particularly important.

A wheelchair user may be able to reach the hallway but still be unable to enter the bathroom safely. Even when the chair technically fits through the opening, there may not be enough room to maneuver once inside.

Bathroom accessibility should therefore be evaluated as a complete system.

The doorway may be one issue, but so are the location of the toilet, shower or tub access, grab bars, flooring, turning space, and the direction in which the bathroom door swings.

In a small bathroom, changing the door configuration may sometimes create additional usable space.

Is Doorway Widening Worth the Cost?

For someone who relies on a wheelchair or other mobility device, a doorway that cannot be navigated safely can effectively make an entire room inaccessible.

That can affect independence far beyond simply getting through a door.

A narrow bathroom doorway may mean needing assistance with personal care. An inaccessible bedroom may require relocating where someone sleeps. A difficult exterior entrance can make leaving and returning home more complicated.

When doorway widening restores access to essential parts of the home, the value is not simply the number of inches added to the opening. It can improve:

• Independence

• Safety

• Mobility

• Caregiver access

• Ease of daily routines

• Long-term usability of the home

For homeowners who want to remain in their homes as they age, these modifications can also be part of a larger plan rather than a response to a single immediate problem.

Knoxville Aging in Place's Aging in Place Roadmap explains how accessibility improvements can be prioritized gradually as needs evolve.

Can You Make a Doorway More Accessible Without Completely Widening It?

Sometimes.

Depending on the existing opening and the amount of additional space needed, alternatives may include different hinges, changing the door style, altering the direction of the swing, or removing a door in a location where privacy and safety are not concerns.

However, these options only help when the resulting clear opening and surrounding maneuvering space are appropriate for the person using the mobility device.

A few extra inches may solve one problem while leaving another.

For example, getting a wheelchair through the doorway does not necessarily mean there is enough room to turn once inside.

That is why doorway accessibility should be evaluated as part of the entire route, not in isolation.

What Knoxville Homeowners Should Ask Before Widening a Doorway

Before starting the project, consider these questions:

What is the current clear opening width?

Measure the usable opening rather than relying only on the advertised width of the door.

What mobility device is being used?

Manual wheelchairs, power chairs, walkers, and other devices have different dimensions and maneuvering needs.

Will the user's mobility needs change?

If the modification is intended to support long-term aging in place, planning only for today's needs may lead to additional work later.

Is the wall structural?

Load-bearing conditions can significantly affect the scope of the project.

What is inside the wall?

Electrical wiring, plumbing, and HVAC components can affect both feasibility and cost.

Is there enough space on both sides of the doorway?

Width alone does not make a doorway accessible if there is inadequate room to approach, turn, or continue moving after passing through it.

Frequently Asked Questions About Doorway Widening

How wide does a doorway need to be for a wheelchair?

The ADA Standards specify a minimum 32-inch clear opening for accessible doorways. In a private home, the ideal width should also account for the individual's wheelchair or mobility device, approach angle, and maneuvering space.

How much does it cost to widen a doorway for wheelchair access?

National estimates vary considerably. Angi's 2026 cost data places the typical national average at approximately $1,200, with projects ranging from around $50 to $3,000 depending on complexity. Knoxville homeowners should obtain a project-specific assessment because structural changes, wiring, plumbing, door type, finishes, and other factors can substantially change the final cost.

Do all doors in a home need to be 36 inches wide?

Not necessarily. The goal in most existing homes is to create adequate clear opening width and an accessible route to the rooms a person needs to use. A professional assessment can help determine which doorways should be prioritized rather than automatically replacing every door.

Can an existing doorway be widened without major remodeling?

Sometimes. A simple interior opening may require relatively limited construction, while other doorways can involve structural framing, electrical relocation, drywall repair, trim, and new doors. The existing wall determines how extensive the work will be.

Should I widen doorways before I actually need a wheelchair?

Planning ahead can make sense, especially if you are already remodeling or expect mobility needs to change. Incorporating accessibility during another renovation may be easier than modifying finished spaces later.

Plan the Right Doorway Modifications for Your Knoxville Home

The cost to widen a doorway for wheelchair access depends on much more than the price of a new door.

The wall structure, amount of additional width needed, door type, electrical or plumbing work, trim, finishes, and surrounding maneuvering space all affect the scope of the project.

Just as importantly, not every doorway necessarily needs modification.

The goal should be to create a practical, accessible path through the parts of the home that matter most while planning for future needs wherever possible.
