Multi-read content how to identify load bearing walls in a house
We all know how important it is to change the structural system of a house.
Accidental removal of a load-bearing wall can cause serious permanent problems to your home or other building structures!
Let’s see how to know if a wall is load-bearing.
Before contacting you, we would like you to note that your municipal government will most likely require you to pass a structural engineering test to determine if the wall is load-bearing prior to removal.
Indeed, altering a home’s structural system without a structural engineer’s inspection or doing much self-study can be a significant short- or long-term “domino effect” problem.
Your house or building can become a house of cards!
However, understanding the basics of load-bearing walls will allow you to budget and ask the structural engineer for feedback on your renovation plan.
1) What is a bearing wall?
Image 1) This image shows a beam resting on a supporting wall. The load is transmitted from the beam, down the column and onto the bracing below.
Load-bearing walls are structural elements of a house that help transmit the weight of the roof, through the floors and to the foundation.
If you remove a load-bearing wall without replacing it with proper supports, you will be removing an important part of the structural system that holds your house upright.
Since loads are transferred from floor to floor in the house, it is common to see bearing walls directly overlapping each floor. Note that I said common, but not absolute.
2) Anatomy of load-bearing walls
Knowing what makes load-bearing walls is key to locating them. Notice image 2 below. This wall has a base plate (single 2×4 or 2×6), studs (single 2×4 or 2×6), and a folded top panel (2-2×4 or 2×6).
2 top panels are required to support the floor spacers and prevent sagging and damage.
Floor joists (typically 2×6 to 2×12) are structural members used to transmit loads to vertical members.
Figure 2) Sketch of a wall with floor spacers perpendicular and stopping on the wall.
The floor joists in this particular photo are perpendicular to the wall and terminate on that wall, suggesting that’s likely where the load is.
If the braces are continuous above the wall, depending on the loads above and below the wall, it can be unloaded. A structural engineer will be needed to determine this.
Here is a great video to explainanatomy.
3) What to expect
Before we dive in and give you the steps to get a general idea of the load-bearing walls in your home, we want you to prepare for what’s to come.
Be aware that most cities will require you to apply for a renovation permit, especially if you plan to alter structural elements.
Even if you or a qualified contractor have experience defining load-bearing walls, the city (in most situations) will require a structural engineer to sign the plan.
Although it may seem like an obstacle preventing you from progressing with your project, it is actually for a good reason.
For example, most people will look at Image 2 and assume that because the braces are perpendicular to the wall and because they end on that wall, the wall is load-bearing.
However, if a structural engineer were to look at this sketch (Figure 2), they would tell you, “It can support the load, but a spot inspection to look at the attic, foundation, and structure is a must.”
No sure bets.
Opening a wall can be like an abnormal box of pandas!
Structural engineers are trained to understand how items such as undersized members (building members) can mean: 1) tons (literally) of deflection or “bouncy” or 2) low strength structural members or insufficient resulting in structural failure or building collapse.
The structural engineer can also provide you with documentation that your wall has been inspected for your protection.
If the wall is load-bearing, many engineers will provide you with a scope of work that your contractor can use to make precise structural changes and to meet required building codes.
4)Basic steps to determine the load-bearing wall
A) Look at any wall you think you want to remove. If the drywall is open, the process will be much easier.
You will need to watchfloor / ceiling Attendees.Notice in the figure below how the floor spacers are perpendicular to the wall. This probably means the wall is under load, but there is not enough information to be sure.
The joists are perpendicular to the wall. Source
Join stop and start perpendicular to this beam.
B) Then follow the wall through the floors of your house. Does the wall rise through the ground directly above itself? If so, here’s another clue that leads us to believe that the wall may be charged.
C) Go up to the attic.Chartered Structural Engineer, Stephen Hammill,Complete constructive solutionsspeak,”Much depends on the load-bearing position of trusses and roof trusses when determining load-bearing walls.”That being said :
1) Have you noticed that people jostling on the ceiling stop and go back perpendicular to the wall? 2) Notice the braces going from the rafters to the wall? If either of these statements is true, chances are you have a load-bearing wall.
The image below shows the ceiling braces against the wall as well as the braces that transmit the load from the roof to the wall.
5)The Legend of the Outer Wall:
Myth: All exterior walls are load-bearing. Reality: Usually, all exterior walls of a house are load-bearing, but not guaranteed.
Many people assume that all exterior walls are load-bearing and weather-resistant. It’s not always the case. It depends on where the bracing and truss support the floor, which varies by house type and style.
Engineer Stephen Hammill, P.E., drew us a simple sketch to explain.
Level 4 house with exterior load-bearing walls
Image 9 shows a house with floor struts and roof trusses perpendicular to each other (top view). They are turned 90 degrees, which means that the 4 outer walls are all load-bearing.
Now look at the image below. Did you notice a difference in the way this house was built? It is long and thin comparable to some trusses. Roof trusses/rafters and struts/floor trusses are parallel to each other.
This means that there are only two walls on which the roof truss/truss and the beam/floor frame bear the load.
The farmhouse has only 2 load-bearing exterior walls
Oh! The legend has been demolished, the exterior walls may not support the load.
6) 4 Factors Structural Engineers Consider When Designing Your New Support System
You now have some ideas for load-bearing walls in your home. It can help you make some very important decisions about your renovation.
Remove the bearing wall and replace it with a beam source
Go ahead and schedule your structural engineering appointment. The engineer may look at the walls you want to remove and tell you: A) Is it load-bearing? B) What should happen if it is loaded?
Remember that structural engineers may be looking for items beyond what we listed in step 4. There may be important hidden components of the house that the engineer might want to analyze.
They can also detect a structural defect, such as a smaller beam, which could alter your renovation plans.Add value…. While you have a structural engineer in place, why not ask about other concerns like walls orfoundation crack,water intrusionor something else, just ask!
Once they have determinedbearing wall, a structural engineer will consider a number of factors when drafting the scope of work for the replacement support system.
The load path is the direction in which eachtonnage(struct weight) will pass through the connected members. Load distribution helps determine if the wall is supporting the load.
It also helps an engineer to create new support systems after the wall is removed. It can be difficult to design solutions and requires a lot of math.
Lift is any upward pressure exerted on a structure capable of lifting it above its surroundings. An engineer will consider this force when removing a bearing wall.
If the wall is removed against wind uplift on the roof, an alternative structural system will also need to resist wind uplift by providing a continuous load path to the foundation. The bottom weight can then resist the lift.
For this to happen, the connections will need to be designed correctly. An engineer will pay particular attention to the connection of the beam to the pillar and all the connections necessary to ensure that the elements move through the floor system.
To block :
These are small pieces of wood in a wood frame structure that are used for things like infill, spacing, assembly, and reinforcing members.
In this case (image below), blocking is used for the payload’s persistent path to the background. Proper transportation is essential to the health of your home.
Plate / plinth strength
Typically, a structural engineer will test the strength of your slab (a common foundation formed from a concrete block) when preparing to design a new structural system to replace load-bearing walls.
If the wall you are removing resists uplift, a foundation may be required.
If you are only dealing with gravity loads, the strength of the slab will need to be tested.
If it is strong enough to support the footprint of the column, no other footing is needed. Otherwise, you will need to cut a section of the slab, dig into the ground and install an appropriately sized foundation.
Deviation from the ground to the pier. This is why it is important for an engineer to inspect the slab to ensure that it is strong enough to support the weight of the column or column. Otherwise, it is necessary to install the sole.
Is scary? The removal of some of these load-bearing walls can be very complex and the structural engineer will have to go through the various calculations and factors above to design the best possible alternative support structure.

Tom Silva explains what load bearing walls are, how to identify them, and what needs to be done in order to safely remove them.

Tom Silva explains how to identify load bearing walls and how to remove them. Load bearing walls are an issue for many renovators today, as more homeowners are opting for an open concept layout instead of individual rooms. Unfortunately, these walls can’t be ripped out haphazardly as load bearing walls play a vital role to the structure of a house. They distribute weight from the roof, through the floors, and down to the foundation. Tom shares tips on how to determine if a wall is load bearing or not. He suggests going down to the basement or attic to see which way the joists run. If the wall is parallel to the joists, it’s probably not load bearing. If the wall is perpendicular, it’s most likely load bearing. Tom then demonstrates two ways of removing these walls, the above-ceiling technique and the below-ceiling technique. These methods will prevent the floor above from sagging and can give you the open layout you desire.
Cost: $1,000 – $10,000
Skill Level: Expert
1. Determine whether a wall is load bearing or not. Check an unfinished basement or attic to see which way the joists run.
a. If the wall runs parallel to the joists, it’s probably not load bearing.
b. If it’s perpendicular, it most likely is a load bearing wall
2. Start by adding temporary walls to either side of the wall being removed to hold up the weight while work is being done. Place the temporary walls close enough to the structural wall but far enough away to work on the structural wall.
3. Remove the load bearing wall.
4. Add posts to either side of the wall to accept a beam to redistribute the weight above. Place them over the weight bearing beam in the floor below.
5. Use one of the techniques Tom demonstrated in the segment: the below-ceiling technique and the above-ceiling technique. Both methods rely on redistributing the weight from the load bearing wall to the walls beside it by creating point loads.
6. In the above-ceiling technique, cut into the joists to allow a beam to be installed in between. The joists will be attached to the new beam and the beam will rest directly on the point loads, but be flush with the ceiling.
7. In the below-ceiling technique, cut the posts slightly shorter and have the joists above rest directly on top of the beam across. The beam will be exposed, but it will keep the floor flush above.
8. Removing a load bearing wall by yourself can result in a lot of costly mistakes. It is best to consult a licensed engineer prior to beginning work on the project.

A load bearing wall means that it is holding the weight of any structure around or above it.
A non-load bearing wall means its not, and its simply there to divide the space.
The quickest way to tell if a wall is load bearing or not is to find out which way the joists above it run. If they run at a 90 degree angle, and your wall is close to the middle of the house, chances are you may be looking at a load bearing wall.
Can’t figure out which way the joists run? Looking at a room, and seeing which is the shortest direction from the outside wall to the middle of the house can also indicate which way they run.
The third easy way is to check is to see if you have a gable roof. If you have a gable roof, which means that one two sides of the roof do NOT have eaves troughs, and the wall runs all the way to a point, then you can easily determine which way the roof trusses run. A quick rule of thumb is that the roof trusses will generally run the same direction as the floor joists. That lets you know that the main beam, and any structural wall will probably run the opposite way.
If none of those quick ways work, you may have to first understand a little more about structural support and why your home is the way it is.
First thing we have to do is understand that the structure of a house is always supported from foundation up. This means that in the ground, there is always some sort of supporting foundation
Typically, there will be concrete piles, or a footing that holds yours basement foundation walls from sinking.
In a typical home, you will have a beam that runs in the middle of the foundation from on side to the other, that will support your floor joists. Then you will have one or a few posts that support underneath the beam.
Moving up to the first floor, you may have to bring that supporting ability up to a second floor, or if in a bungalow, into the roof system. A typical house will have a supporting wall almost directly above the basement beam.
Go to the basement and check to see if you can find any open supporting structures
These include Posts that are in the middle of the basement, or open beams that space across the middle of the home. Beam can be made out of different material, including, wood, LVL, or even steel. Newer homes hide them well, unless the basement is unfinished. Do you have a drop ceiling anywhere?
It’s important to know which way the joists run above every level, because they may NOT always run the same way in the basement, as they in the first or second floors.
We have found our beam, as we don’t generally have supporting interior walls in the basement, and that typically means that there will be a supporting wall directly above or close on the floor above.
You will see a wall supporting perpendicular joists. Perpendicular simply means they run at a 90 degree angle across. That allows the wall to support they weight of the floor system.
1)Here are some other ways to find the joists in your ceiling.
you may need to use a stud finder
2)see if you can find multiple drywall screws that will show you where your joists are
3)cut into the ceiling and check.
4)There is also an option to find the old building plans.
When you’re updating a home, it’s common to think about reconfiguring the interior walls. Perhaps you want to make the space more efficient or bring in more natural light. Or maybe you want to remodel a kitchen or bathroom.
When changes involve moving walls, the question often comes up: “Are these load-bearing or partition walls?” Instinctively, most people know it’s more complex to work with load-bearing walls than partition walls. But how can you tell if a wall is load-bearing when you can’t see the framing? There are quite a few signs to help you answer this question.
