Is That Wall Load Bearing? A Beaverton Homeowner's Guide
Most interior demolition jobs around Beaverton start the same way. The homeowner wants one wall gone. Fair enough. Builders put up a lot of homes here from the 1960s through the 1980s. Back then, they closed off kitchens and tucked living rooms behind hallways. Today most people want that space open.
But a wall can do more work than it shows. Some walls hold up the roof. Some carry the floor above. Others hide pipes, wires, or a heating duct nobody remembers. Older homes add another twist. Past owners may have moved things around and never told anyone.
So check before you cut. This guide shows you what to look for. It also tells you what to do when the answer isn't clear.
What Is a Load Bearing Wall?
A load bearing wall carries weight from above down to the foundation. That weight might be the roof, a second floor, or both. A partition wall only divides a room. It holds up nothing but itself.
Exterior walls almost always carry load. Interior walls are harder to read. Two walls can look the same from the hallway and do very different jobs.
How Can You Tell If a Wall Is Load Bearing?
You can't know for sure until you see the framing. Still, a few clues point the right way:
- Joist direction. Check the attic. Walls that cross the joists at a right angle often support them.
- What sits below. Look in the crawlspace. A beam, a row of posts, or a foundation wall under the wall is a strong sign.
- What sits above. A wall under another wall upstairs usually carries load.
- Heavy framing. A deep header over a doorway means the wall holds something up.
No single clue proves it. Each one tells you to look closer.
Which Walls Are Usually Structural in Local Homes?
The wall down the middle of the house is the usual suspect. It often runs parallel to the roof ridge. The answer changes with the style of home.
| Home style | Where structural walls usually show up |
|---|---|
| Older single story ranch | A central wall running the length of the house |
| Ranch with roof trusses | Often only the exterior walls. Confirm in the attic. |
| Split level | Walls at the level change and under the upper floor |
| Two story | Main floor walls under upstairs walls or floor joists |
Garage conversions and additions change things. If your house has either, don't trust the original layout.
What Else Could Be Hiding Inside the Wall?
Pipes, wires, gas lines, ducts, and sometimes asbestos hide inside walls. Any of them can change your plan. You can move a couple of outlets easily. A drain stack or furnace return takes real work.
Asbestos needs extra care. Oregon DEQ rules call for a survey before contractors renovate or demolish homes built before 2004. An accredited inspector has to do it. Asbestos often shows up in old wall texture, joint compound, and flooring. You can't spot it by eye. Get asbestos testing done before anyone opens the wall.
How Does Wet Weather Affect What's Behind the Drywall?
Rain causes many of the surprises behind drywall in the Tualatin Valley. Roof leaks drip slowly. Window flashing wears out. Crawlspaces stay damp. All of it can soften framing for years, and the surface may show nothing.
Rot changes how a wall behaves. A weak bearing wall may already struggle. A simple partition may end up propping a sagging section next to it. So look first. Check for water stains, soft spots near the floor, sloping floors, and doors that stick.
Can a Load Bearing Wall Still Be Removed?
Yes, in most cases. The load just needs a new path first. A structural engineer sizes a beam and the posts under it. Those posts carry the weight down to proper footings. Temporary shoring holds the house up while the old wall comes out.
You'll need a building permit for structural changes. Inside city limits, the City of Beaverton handles it. Many homes with a Beaverton mailing address sit in unincorporated Washington County, including much of Aloha. Confirm which office covers your address first.
Then the wall comes out. Careful interior demolition removes what needs to go and leaves the rest of the house alone.
What Should You Watch for After the Wall Comes Out?
A properly sized beam shouldn't move much. Your house will tell you if something's off. Watch the new opening through the first wet season.
- Hairline cracks at drywall seams are normal as new lumber dries.
- Call your engineer if cracks widen or run diagonally from door corners.
- Sticking doors or a dip in the floor under a post point to settling.
Keep your paperwork too. File the engineer's letter, the permit sign off, and the asbestos survey with your house records.
Frequently Asked Questions
Are all exterior walls load bearing?
Almost always, yes. They carry the roof and tie the house together. A new opening in one needs the same engineering as an interior bearing wall.
Can I remove only part of a load bearing wall?
Yes, often. You can widen a doorway or cut a pass through. You'll still need a properly sized header, because the weight above doesn't go away.
Do original house plans show which walls are structural?
Sometimes, but don't rely on them alone. Plans rarely show later remodels. The framing inside the wall tells you more than any drawing.
Does a doorway mean the wall isn't load bearing?
No. Plenty of bearing walls have doorways. Look at the header above the opening. A deep one tells you weight comes down from above.
Who makes the final call on whether a wall is structural?
A structural engineer does. Open a small section of drywall first. That way the engineer sees the real framing and doesn't have to guess.
