Before you commit to hiring an engineer for a load-bearing wall removal, you'd like to at least know whether the wall is actually load-bearing — partly out of curiosity, partly because if it isn't, you don't need the letter. Here are the practical, non-destructive checks you can do yourself, in order of reliability.
1. Look at the joists above
The most useful single clue. Floor or ceiling joists run in one direction across the house. If the joists run perpendicular to (across) the wall in question, the wall is probably bearing those joists. If they run parallel to the wall, the wall might be a partition wall.
How to check without tearing drywall: in an unfinished basement or attic above the wall, you can usually see the joists directly. Look at their direction and trace it back to the wall in question. If you can't see directly, sometimes the nail pattern in the ceiling drywall reveals joist direction (the screws line up where the studs are).
2. Look in the basement or crawlspace below
Walk down to the basement and stand directly beneath where the wall is on the floor above. Is there a beam, post, or wall directly under it? If yes, that's a strong indication the upper wall is bearing — the lower structure was put there specifically to carry the load coming down.
If there's nothing under the wall — just open basement space — the wall might still be bearing (it could be supported by a beam in the floor structure), but it's a weaker indication.
3. Look at the wall framing itself
Bearing walls are usually framed differently than partitions:
- 2x6 studs instead of 2x4 (especially in older homes where 2x4 partitions are common)
- Tighter stud spacing (12" or 16" on center vs. wider for partitions)
- Headers above doorways in the wall — if there's a real structural header (a doubled-up 2x10 or larger above a door opening), the wall is probably bearing
- Continuous from the foundation up — bearing walls usually go all the way down to a foundation, not just sit on the floor
You can check stud spacing with a stud finder or by looking at the screw pattern in the drywall.
4. Look at the original house plans
If you have the original construction drawings, bearing walls are usually identified — they may have framing notes, header callouts, or be drawn with double lines. Most homeowners don't have the original plans, but it's worth checking with your city building department, who often have them on file for homes built since the 1980s.
The honest limit of these checks
None of the above is definitive on its own. Houses sometimes have walls that look like partitions but are part of the lateral system (shear walls), which means removing them compromises seismic performance even if they're not gravity bearing. Modern homes have engineered floor systems that don't always follow the rules of thumb. And older homes have been modified over the years in ways that don't match the original plans.
If you're 90% sure a wall isn't bearing and you're planning a small project, you might be okay relying on your own checks. If you're going to remove the wall and you want to be sure, send us photos. About a third of the time we can tell you from photos that the wall is or isn't bearing — for free, because that's the right thing to do for someone who might become a customer later.
What we'd ask you to send
- A photo of the wall from inside the room
- A photo or sketch of the floor plan around the wall
- A photo of the basement directly under the wall
- The number of stories above
