How to Remove Thresholds and Widen Doorways for Wheelchair Access

TL;DR: Most interior thresholds can be removed in under an hour with a reciprocating saw and wood filler; exterior thresholds often need a low-slope replacement to meet weather-seal and ADA ½″ height limits. Widening a doorway to the ADA-recommended 36″ clear width typically requires removing casing, cutting studs, installing a new header, and reframing—budget $1,200–$3,500 per opening when you hire a carpenter, or plan a full weekend if you're doing it yourself and confident with framing.

A wheelchair, walker, or hospital bed changes the way a house works. Thresholds that once went unnoticed become three-quarter-inch obstacles; doorways that felt generous suddenly measure two inches too narrow for a 24″ chair plus knuckle clearance. Whether you're aging in place, retrofitting for a family member, or preparing a rental for broader tenant access, removing thresholds and widening doorways are two of the most impactful modifications you can make—and both are within reach of a determined DIYer or a skilled carpenter working over a weekend.

Okoniq Property Hub logs each accessibility improvement with photos and receipts, so you have a time-stamped record for resale disclosures, insurance claims, or Section 8 reasonable-accommodation documentation.

What tools and clearances do you need to remove an interior threshold safely?

Interior thresholds—the wooden or metal strips between rooms—exist to cover the seam where two types of flooring meet or to provide a slight weather barrier at exterior doors. Removing them is straightforward: use a reciprocating saw with a short metal-cutting blade (for aluminum thresholds) or a wood blade (for oak saddles), cut the threshold into two or three sections without hitting the subfloor, then pry out the pieces with a flat bar. Wear safety glasses; the saw will kick dust and metal shavings.

Once the threshold is gone, fill screw holes or nail pockets with wood filler, let it cure for two hours, then sand flush. If the flooring underneath is unfinished or discolored, you have three options: install a flush transition strip (look for ADA-compliant models under ¼″ high and beveled on both edges), stain or paint the bare strip to match, or leave it as-is if the height difference is less than ¼″—ADA guidelines allow that without a bevel.

Track the work: take before and after photos, note the date, and save the receipt for any transition strips or filler you buy. If you're modifying a rental to accommodate a tenant's disability, reasonable-accommodation records are your documentation that you acted in good faith. For detailed guidance on organizing this kind of maintenance history, see our post on how to diagnose a ceiling water stain—the same log-first principle applies.

When does an exterior threshold need replacing instead of removing, and what height meets ADA standards?

Exterior thresholds serve a weather function: they shed rain away from the door sill and provide a compression point for the door sweep. Removing one outright will let water into the subfloor during storms. Instead, replace the standard threshold—often ¾″ to 1″ high—with an ADA-compliant low-profile model that measures ½″ or less and includes a beveled edge on both sides.

Pemko, National Guard, and Frost King all make aluminum thresholds rated for exterior use at ½″ height; they cost $40–$80 depending on width and finish. Installation takes 30 minutes: remove the old threshold with the same reciprocating-saw method, clean the sill, apply a bead of exterior caulk along the back edge, set the new threshold in place, and fasten it with the provided screws (typically four per threshold). Check that the door sweep still makes contact—trim it if necessary so it compresses against the new lower surface without dragging.

If the door opens outward and you're working on a rental covered by Fair Housing Act rules, remember that a ½″ threshold with beveled edges is considered compliant for reasonable accommodation; anything taller requires a short ramp, which we'll address in the next section.

How do you widen a doorway to 36 inches clear, and what does the framing work involve?

A standard interior door in a pre-1990 house is usually 30″ wide (the door slab itself); the rough opening is 32½″, and after you account for jambs and stops, the clear passage width is closer to 28″–29″. A wheelchair needs 32″ minimum (ADA standard for new construction) and ideally 36″ clear for comfortable two-way traffic or for someone learning to maneuver. That means you're swapping to a 36″ door slab, which requires a 38½″ rough opening—8″ wider than the typical old frame.

The steps: remove the existing door, casing, and jamb; pull the drywall back six inches on each side to expose the framing; identify which studs are load-bearing (if the doorway sits under a beam or perpendicular to ceiling joists, it's load-bearing and you need a structural header—consult local code, usually a double 2×6 or 2×8 for spans under four feet); cut and remove the old king studs and jack studs; install new king studs at the wider marks, nail in jack studs, and lift a properly sized header into place; then frame cripple studs above the header if the wall is load-bearing. Once the framing is solid, hang new drywall, tape and mud the seams, prime, paint, and install the new 36″ prehung door.

Time: expect 8–12 hours for a confident DIYer, two to three days if you're learning framing for the first time. Cost: if you hire a finish carpenter, plan on $1,200–$2,000 for labor, plus $300–$500 for the door, jamb, casing, drywall, and paint—total $1,500–$3,500 depending on whether the wall is load-bearing and whether you're matching custom trim. Document every stage with photos in Okoniq; if you later sell or refinance, the appraiser will see the work as a functional improvement, not a liability. For a similar framing-and-finish project, see our post on replacing a ceiling light fixture—the attention to electrical boxes parallels the care you need with door headers.

What permits and inspections apply, and how do you handle a load-bearing wall safely?

Most jurisdictions require a building permit when you're cutting or moving studs in a load-bearing wall; non-load-bearing partition walls sometimes slide under the radar, but it's safer to call the permit office and ask. The inspector will check three things: header size (verified by span tables in the IRC or your local building code), fastener schedule (nails every 16″ on studs, nails or structural screws through the header into the king studs), and shear-wall impact (if the wall is part of the home's lateral bracing system, you may need an engineered solution or additional hold-downs).

If you're unsure whether the wall is load-bearing, look in the attic or basement: if ceiling joists or floor joists run parallel to the wall, it's probably not load-bearing; if they run perpendicular or if a beam sits directly above, it is. When in doubt, hire a structural engineer for a one-hour consult ($150–$300)—far cheaper than a sagging ceiling. Never cut a load-bearing stud without temporary shoring in place: jack posts or a temporary wall built three feet away on each side, snug against the ceiling.

Log the permit number, inspection date, and any engineer's letter in Okoniq. If the work is part of a Section 8 reasonable accommodation, HUD may ask for proof that it was done to code. For related permitting advice, read our guide on attic ventilation balance—the same principle of measuring twice and calling the inspector once applies.

Do ramps or lifts become necessary after widening, and what are the cost trade-offs?

Once thresholds are removed or lowered and doorways widened, you've addressed the two biggest indoor barriers. The next question is vertical access: if the entrance has steps, you'll need either a ramp (permanent or modular) or a vertical platform lift. A wooden ramp built to ADA slope (1:12—one foot of run for every inch of rise) costs $100–$150 per linear foot if you build it yourself, $200–$300 per foot installed by a contractor. For a 24″ rise (two steps), that's 24 feet of ramp and $2,400–$7,200 total.

Modular aluminum ramps rent for $100–$200 per month or buy outright for $1,500–$5,000 depending on configuration; they're faster to install (one day) and removable if you move. Vertical platform lifts cost $5,000–$15,000 installed and work when space for a ramp doesn't exist; they require 220V power and annual maintenance. Compare the household's timeline: if the need is temporary (post-surgery recovery), rent; if permanent, build.

Track all costs and decisions in Okoniq—ramp inspections, lift service contracts, and材料 receipts become part of the property's permanent record. For another example of choosing between DIY and professional help based on complexity, see our post on attic mold remediation.

FAQ

How much does it cost to remove a threshold yourself versus hiring someone?

DIY threshold removal costs under $50 (reciprocating-saw blade, wood filler, sandpaper) and takes 20–40 minutes. Hiring a handyman runs $75–$150 for a single threshold; carpenters typically bundle it with other trim work and charge $100–$200.

Can I widen a doorway in a condo or rental without violating my lease or HOA rules?

Check your lease or CC&Rs first—most allow interior modifications if you restore the space when you move, but load-bearing wall changes often require board or landlord approval and a licensed contractor. Document everything in writing and keep permits on file.

What if my hallway is too narrow for a 36-inch door to swing fully open?

Switch to a pocket door (slides into the wall) or a swing-clear hinge that moves the door out of the opening when it's 90° open, gaining you an extra 2″ of clear width. Pocket-door frames cost $150–$300 and require wall cavity depth of at least 4½″.

Do I need an engineer's stamp to widen a doorway in a load-bearing wall?

Not always—if you follow IRC span tables and your local code's prescriptive path, the building inspector may approve it without an engineer. But if the span exceeds code table limits, if the wall has a point load above it, or if the inspector asks for calcs, you'll need a PE letter ($200–$500).

How do I match new trim and paint when widening a doorway in an older house?

Take a piece of the old casing to a millwork shop for profile matching, or search architectural salvage yards for period-appropriate stock. For paint, chip a small sample from an inconspicuous spot and have a paint store scan it for a custom match—most chains do this for free.

This is educational information, not structural engineering or legal advice. Consult a licensed structural engineer before cutting load-bearing members, and check your local building department for permit requirements. If modifying a rental or condo, review your lease and HOA covenants before starting work.
