Pay attention to what is directly above the wall. If there is another wall, a floor with perpendicular joists, or other heavy construction above it, it is probably a load bearing wall. However, if there is an unfinished space like an empty attic without a full floor, the wall probably is not bearing a load.
How do I know if my wall is load bearing?
The direction of the joists above your wall can be indicative of whether the wall is load bearing or not. Many times, if the joists run perpendicular to the wall, it is load bearing. This is not always the case, but is a good starting point. Look at the photo below. Notice how the joists above the wall run perpendicular to the wall itself.
Is a wall load-bearing?
But if the wall runs perpendicular (at a 90-degree angle) to the joists, there is a good chance that it is load-bearing. However, there are cases where a bearing wall is parallel to the joists. In this case, the wall may be aligned directly under a single joist or bear on blocking between two neighboring joists. Is a Partial Wall Load-Bearing?
How do I find the load-bearing walls of my house?
Start at the lowest point in your house. To begin determining which walls in your house are load-bearing ones, it's best to start at the most basic load-bearing feature of any home - the foundation. If your house has a basement, start here. If not, try to start wherever on the first floor you can locate your house's lower concrete "slab."
How does the size of a house affect its load bearing walls?
The bigger a house is, the farther apart its load bearing exterior walls will be and, thus, the more load bearing internal walls there will need to be to support the floor. Often, these load bearing walls are roughly near the center of the house because the center of the house is the farthest point from any of the exterior walls.
Is there an easy way to tell if a wall is load-bearing?
Step 1: Determine Whether a Wall Is Load-Bearing or Not Check an unfinished basement or attic to see which way the joists run. If the wall runs parallel to the joists, it's probably not load-bearing. If it's perpendicular, it most likely is a load-bearing wall.
How can you tell if a wall is load-bearing or beam?
From a basement or crawlspace, check to see if another wall or support structure is directly below a first-floor wall. If a wall has a beam, column or other wall directly below or following its same path, it's a load-bearing wall. Walls more than 6 inches thick are usually load-bearing walls.
Do house blueprints show load bearing walls?
Load-Bearing Wall Checklist The original blueprints for the home will tell you which walls are load bearing and which ones are not. If a wall is marked as “S” in the blueprint, this means “structural,” thus showing it's a load-bearing wall.
How do contractors know if wall is load-bearing?
The easiest way to determine if a wall is holding up the weight of the house is to look underneath. Look for large beams, called floor joists, running under the wall. If the joist is directly under the wall in question, it is a load-bearing wall.
How can you tell if a wall is load-bearing without removing drywall?
Generally, when the wall in question runs parallel to the floor joists above, it is not a load-bearing wall. But if the wall runs perpendicular (at a 90-degree angle) to the joists, there is a good chance that it is load-bearing. However, there are cases where a bearing wall is parallel to the joists.

If the wall is not load-bearing, then it shouldn't be a problem to remove, provided you know what you're doing and take all the necessary precautions. If, however, the wall is load-bearing, you may need to get help from a structural engineer who can provide you with a structural engineer's report.
How much does it cost to find out if a wall is load bearing?
How Much will it Cost? To remove a load-bearing wall, construction will likely cost between $1,200 and $3,000 if you have a single-story home, and between $3,200 and $10,000 for multi-story homes. For a partition wall, the cost is between $300 and $1,000.
Can you put a door in a load-bearing wall?
You can definitely have doors in load bearing walls. You can't take out a stud that bears the end of the load (like a corner) because you wouldn't be able to redistribute the weight. It would help to see the wall though. Just make sure you have the right size header set on jack studs to take the weight.
Do modern houses have load-bearing walls?
Remember that most home's exterior walls are load bearing. Regardless of whether it's made of wood, brick or another material, nearly all exterior walls will extend right into the concrete; thus, you may want to think twice before knocking down an external load-bearing wall.

Where to check for internal walls?
Check for internal walls near the center of the house. The bigger a house is, the farther apart its load bearing exterior walls will be and, thus, the more load bearing internal walls there will need to be to support the floor.
What does it mean when a wall is perpendicular to the floor?
Absolutely! If a wall forms a right angle with your floor joists (or, to put it another way, if the wall is perpendicular to the joists), that means that the joists are transferring load to that wall. The wall is therefore load bearing. Read on for another quiz question.
Can a load bearing wall be a support beam?
Internal load bearing walls can incorporate the house's main support beams into the construction of the wall itself. However, because these support beams are relatively large compared to non-load bearing studs, often, the wall itself will be designed to accommodate the extra size of the beam.
Can you modify a load bearing wall?
Before modifying any walls in your home, it's important to be very sure which walls are and aren't load bearing, as removing or modifying a load bearing wall can compromise your homes' structural stability with potentially disastrous consequences.
Can a wall be removed if a joist meets a wall?
If any of these joists meet a wall or a main support beam at a perpendicular angle, they are transferring the weight of the floor above into the wall and, thus, the wall is load bearing and should not be removed. Again, because most walls' supports are behind drywall, they can't be seen.
Can a beam be removed from a wall?
If your beam spans from the foundation through any wall above it, the wall is load bearing and should not be removed.

What direction do ceiling joists run?
See the photo below. Ceiling joists running perpendicular to center wall in gable roof. Knowing which way the ceiling joists go is very useful information. One reason is that, typically, the main structural beam of the house will run perpendicular to the ceiling joists.
What is the main structural beam?
Look for the main structural beam: The main structural beam is the primary beam in the home responsible for holding up other smaller beams and other structural components. It’s always easier to find a home’s structural beam/s when the basement is unfinished versus when it is finished.
What is the best way to replace a wall?
You must replace the wall with a system capable of carrying the same load (or more depending on several factors). A common solution is a beam and column system. A structural engineer is capable of engineering a beam and column strong enough to distribute whatever loads are present.
What is a joist in construction?
First off, let’s define what a joist is. A joist is a horizontal structural member, running across an open space, that is used to transfer loads to vertical members, typically, floors & ceilings . See the photo below.
Do joists end on the wall?
On top of this, some of the joists actually end on the wall. This is a sure sign that this wall is structural (load bearing). Most times, if the joists run parallel to the wall, the wall is non-load bearing.
How do load bearing walls work?
Load-bearing walls cross roof beams in a perpendicular direction . Using this technique, you’ll get a better idea of the location of the load-bearing walls in your house.

What is load bearing wall?
Load bearing walls, also known as weight bearing walls, are a critical structural element in your home. To put it simply, these walls do exactly what their name implies — they hold the weight of the building. Think of these walls as a network of load distributors that take all the weight from the house and transfer it into the foundation.
How to transfer weight horizontally through a house?
Attach directly to or sit on top of beams to transfer weight horizontally through the house. Can be vertical or horizontal, depending on location. Transfer load to columns or foundation. Attach to walls or pillars to transfer weight vertically through the structure of a house.
What is the difference between a beam and a joist?
Joists are the many pieces of wood or metal that run parallel to each other for the length of a room to support the floor above. Beams are thicker pieces of wood or metal that can be either horizontal or vertical and intersect the joists to help move the weight of the home toward the foundation.
Do you need a plan for removing load bearing walls?
If the bearing wall must go, you need to have a plan. It doesn’t matter how much or little of the load bearing wall you plan on removing, the weight needs to be redistributed. Often, a beam known as a header or wall-to-floor-pillars get installed to compensate.
Where are reinforcement posts and columns in a home?
Reinforcement posts and columns are obvious in a basement or attic, but on other floors, they are not always as noticeable. Ways to identify potential extra wall support in finished areas of a home include: Pillars at the seam of two walls. Extra supports around door and window frames.
Can drywall cracks be horizontal?
Vertical cracks in drywall are normal and usually at the seam. It takes a lot of force to horizontal ly crack dry wall.
What is a load bearing wall?
A load-bearing wall is any wall that holds up the weight of the structure above and the people/furniture supported by that structure. The floors above, roof structure, people and furniture are the “ loads ” that the wall has to support. A load-bearing wall transfers load all the way down to the building’s foundation.
What is required to replace a bearing wall?
When removing a bearing wall in a residential home, a beam or lintel is required to replace the wall and carry the load to each side of the opening. A beam can either be dropped and have the floor joists sit on top of it, or the beam can be in the same plane as the joists having the joists frame into the side of the beam.
How far should floor joists span?
The joist span depends on the wood species/grade, applied load and joist depth/spacing but a good rule of thumb would be that a joist will span between 10 and 20 feet (3 and 6 m).
What is the role of a wall in a building?
Other than transferring load, the role of a wall in a building include: To separate rooms and spaces. To provide acoustic separation and prevent sound travel. To prevent fire from spreading from one space to another. To provide aesthetics to a space. To provide shelter. To enclose conduits and plumbing.
Can you flush joists into a beam?
Flush framing joists into the side of the beam is a more expensive option as it can involve cutting the jo ists and installing joist hangers at the ends of the joists . This option, however, can elimina te the need for a bulkhead that would be required if the beam was dropped, which leads to a cleaner look.
Can you see floor joists on a roof?
If you are able to see the floor framing or roof framing, you first want to locate the floor joists or roof trusses. If the wall in question is parallel to the joists/trusses, it will likely not be load-bearing. An example of a non-load bearing partition wall can be seen on the left. When joists/trusses are perpendicular to the wall and bear on ...
Is joist continuous?
Joists are rarely continuous over the top of a wall, instead, they are often spliced over the top of the wall as dimensional lumber only available in specific lengths. For an idea of the standard lengths of dimensional lumber click here. If you don’t have access, it is safe to say that all exterior walls are load-bearing.
How to check if a wall is load bearing?
One of the best ways to figure out whether a wall is load bearing is to check if joists are sitting on top of it. You can do this in a couple of ways: 1 Use a stud finder along the ceiling next to the wall in question and see if any joists running perpendicular to it are present. 2 Open up the ceiling and do a visual check.
Which way do load bearing walls run?
