You can't remove a load-bearing wall without replacing what it does: the floor or roof that sat on it still needs a path down to the foundation. What you can change is the form that support takes. The common alternatives to a visible dropped beam are a flush beam hidden in the ceiling, a beam above the ceiling in the attic with the ceiling hung from it, posts with shorter beams, or a partial removal that leaves piers or stub walls. Each one is designed by an engineer or qualified designer and built under a permit.
Here's what each option involves, so you can ask for the one that suits your layout.
First, confirm the wall is load-bearing
Not every wall people worry about is structural. Before you plan around a beam, have the wall assessed. Signs a wall may be load-bearing include:
- Joists or rafters landing on it from one or both sides, or lapping over it
- A beam, wall or posts directly below it in the basement
- A wall directly above it on the next floor
- Its position near the middle of the house, running perpendicular to the joists
In many newer houses with engineered roof trusses, interior walls on the top floor carry no roof load. In older houses, and on lower floors of any house, interior walls often do. A designer or engineer confirms this by opening up the ceiling or reading the original drawings. Guessing wrong is the expensive mistake here.
Why "no beam" isn't an option
The Ontario Building Code is direct about this. Under Article 9.23.12.2 of the 2024 OBC (O. Reg. 163/24), openings in loadbearing walls that are wider than the required stud spacing must be framed with lintels designed to carry the superimposed loads to the adjacent studs. A lintel or header over a door is a short beam. Make the opening the whole length of the room and that member becomes a full beam, with posts and footings at its ends.
So the question isn't really whether there will be a beam. It's where it goes, what it's made of and whether you'll see it. Removing a load-bearing wall is also a structural alteration that needs a building permit everywhere in the GTA; see permits for load-bearing wall removal.
Option 1: A flush beam hidden in the ceiling
This is what most people mean by "no beam". Instead of hanging below the ceiling, the beam sits within the depth of the floor joists, and the joists on both sides are connected to its sides with hangers or seats. The finished ceiling runs straight across.
What it involves:
- Opening the ceiling along the full length so joists can be cut back and reconnected
- Depth limits. The beam has to fit within the joist depth, so it's usually a heavier, shallower section. Steel suits flush beams because it carries a lot of load in a shallow depth.
- Connections for every joist. Hangers, or a wood nailer bolted to the steel, so the joists can be fastened. See attaching a wood nailer to a steel beam.
- Posts and footings at each end, hidden in walls where possible
Our comparison of steel beam vs LVL strength and depth covers why depth often decides the material.
Option 2: A beam above the ceiling
In a single-storey house, or where the wall only carries the ceiling and roof, an engineer may put the beam in the attic instead, above the ceiling joists, and hang the ceiling from it. The room below has a clean ceiling and nothing is cut into the floor framing.
It isn't always possible. The attic needs room for the beam and access to get it in, the roof framing has to suit it, and the beam still needs supports that carry load down through the walls to the foundation. Trusses can't be cut or altered unless the truss design allows for it (Article 9.23.5.5), so truss roofs limit what can be done. This is very much an engineer's detail.
Option 3: Posts with shorter beams
If you don't mind a post or two, they can work in your favour. A beam's required size grows quickly with its span, so splitting one long span into two shorter ones can make the beam much smaller, sometimes small enough to sit flush.
Things to know:
- Columns alone don't replace a wall. Joists that bore on the wall need something continuous to bear on, so the posts always support a beam.
- Every post needs a footing. Each post brings a concentrated load down to the basement, where it needs a footing sized for that load and a post or column below if there's another floor in between.
- Placement matters. A post at the end of a kitchen island, or framed into a half wall, can disappear into the design.
Steel posts are slim for the load they carry, which makes them easier to hide in a wall or cabinet run.
Option 4: Partial removal
Sometimes the best answer is to keep part of the wall:
- A wider doorway or cased opening with a header sized for the new width
- Stub walls or piers at one or both ends, which shorten the span and give somewhere to put the posts
- A pass-through with a header above and the wall below kept as a counter-height ledge
"How much of a load-bearing wall can be removed?" has no fixed answer. With a properly designed beam, posts and footings, the whole wall can go. Leaving a section in place reduces the span, the beam size and sometimes the work in the basement.
Small changes: one stud, a door frame
Two smaller questions come up often:
- Removing one stud. It sounds harmless, but taking out a stud creates an opening wider than the stud spacing, which, as above, needs a lintel. Cutting or notching loadbearing studs is limited too: Article 9.23.5.3 requires at least two thirds of a loadbearing stud's depth to remain undamaged unless it's suitably reinforced.
- Removing a door frame. The jamb and trim in a doorway are finishing, not structure, so taking them out to make a cased opening doesn't change the load path. Widening the rough opening does, because the header over it was sized for the original width.
Comparing the options
| Option | Visible result | Main trade-off |
|---|---|---|
| Dropped beam | Beam below the ceiling | Simplest framing; takes headroom |
| Flush beam | Flat ceiling | Ceiling work and joist connections; shallow, heavier beam |
| Beam above the ceiling | Flat ceiling, no floor cutting | Needs attic space and suitable roof framing |
| Posts and shorter beams | One or more posts in the room | Smaller beams; more footings |
| Partial removal | Piers, stub walls or a wide doorway | Less open; less structure to replace |
Whichever you choose, the sequence is similar: design, permit, temporary shoring, removal, new beam and posts, inspection, finishing. Our post on how to remove a load-bearing wall and install a beam walks through what happens on site, and load-bearing wall removal cost explains what drives the budget.
Steel for whichever option you choose
Flush beams, beams above the ceiling, posts and shorter beams all end up as steel that has to be fabricated to the drawings: cut to length, with cap and base plates, holes for nailers and connections. Send us your engineer's drawings for a quote, or tell us about the wall if you don't have drawings yet; engineering services are available for projects that need them. We supply and install basement beams and posts across the GTA and Ontario. See our steel products for beams, posts and plates.
Frequently asked questions
Can you remove a load-bearing wall without putting in a beam?
Not without replacing what the wall does. Something has to carry the floor or roof above down to the foundation. What you can change is where that support goes and how visible it is, for example a flush beam hidden in the ceiling, a beam above the ceiling in the attic, or posts with shorter beams.
Can you replace a load-bearing wall with columns?
Columns alone can't carry joists that ran onto the wall, so they always support a beam. Adding columns at intervals shortens the beam's span, which makes the beam smaller, but each column needs a proper footing and a load path to the foundation.
How much of a load-bearing wall can be removed?
Any length can be removed if the replacement beam, posts and footings are designed for it. Leaving short sections of wall or posts in place reduces the span and the size of the beam. An engineer or qualified designer works out the options for your house.
Can I remove one stud from a load-bearing wall?
Removing a stud creates an opening wider than the stud spacing, and the Ontario Building Code requires openings like that in loadbearing walls to be framed with a lintel that carries the loads to the adjacent studs. In other words, it needs a header, not just a gap.
