My question is for both load and non-load bearing walls.

There used to be a hinged door between the kitchen and dining room, who knows when it was removed (I've been here a couple years). The door frame is still intact. The opening is roughly 6'8" high and I'd like to know if I can extend this opening all the way up to the 8' ceiling.

For the second situation, I have a small hall that ends in a T-intersection where you need to turn left or right towards bedrooms. This might be part of a load-bearing "line" of the house, for my question lets assume it is. Similarly, can I remove the wall above this opening such that the passageway opening goes straight up to the ceiling?

I'm unclear on what the header, king, and jack requirements are for a passageway that has no door attached.

Edit: Above the ceiling is 24" tall 'attic' under a flat roof. 2x6 ceiling joists 16 OC and 2x6 roof rafters 32 OC.

    The presence of a door has no impact whatsoever on whether a header is required for an opening in a wall. If the wall is load bearing, as you're presuming it is, then no, you cannot extend the opening all the way to the bottom of the joists. If you do, you'll leave them unsupported and they will, eventually sag, perhaps collapse. – FreeMan Feb 1 at 17:02
  • Do you have a pitched/gabled roof? If so which way does it pitch relative to the doorway in the photo? If you have access to an attic it should be easy to tell if this is a load bearing wall. The load bearing walls will typically be running along the same direction as the main axis of the roof. – TylerH Feb 4 at 19:41

What are the requirements for a header for an open passageway through two rooms?

The answer to that question is project specific. Some general advice below, but the project specific requirements depend on local regulations as well as the structural requirements of the design itself.


Obligatory: hire an engineering firm to investigate and "be sure" (in quotes because engineers can be wrong, and really what we hire an engineer for is in large part to take on liability for problems caused by proceeding with the work).

That said: yes, you should be able to delete the intermediate headers ("drop headers") on interior partition walls in single family, wood framed, residential construction in the USA without impacting the structural integrity of your home in both your first and second cases. Generally speaking, you'll want to selectively demolish layer by layer and make sure you reconfigure any structural "Load Bearing" elements appropriately. What I mean is, if you pull the gyp board off and find that the wall is sheathed with a tight nailing pattern and is clearly "built up" (more than just 2x4s and gyp board) beneath the gyp board, then you should assume you have a shear wall. Otherwise, as far as single family typical residential construction in the USA goes, any structural elements in a wall with an opening (like the doorway) should be directly beneath the Load (in this case, at the top of the wall (note: where no cracking or other defects are visible which might imply that the opening was cut into a structural wall as a renovation and compromised the integrity of the "work" the wall is performing). In your case, I don't know of any reason why a structural header would be built above a doorway with a pony wall above it supporting the actual load.

  1. To address your first scenario in specific terms, the picture shown above: If the information above applies and is accurate, and we determine it is reasonable to proceed assuming this is not a shear wall, you have two options in the event this is carrying a joist running perpendicular to a Structural Header at the ceiling plane above the doorway header:

    • Demolish the wall up to the header at the top of the wall.
    • Learn some framing tricks, strap the load to an adequate (including appropriate safety factor) beam riding above the joist thereby transfering the load, and delete the wall all the way to the ceiling plane.
  2. To address your second scenario in specific terms (the T intersection):

    • Same as above, if you go into your attic, and you don't see any bracing from the roof to the ceiling joists riding on the plate above the openings, and if everything else above has been followed and you determine to proceed accordingly, the only problem impact you might find is cracking from settling.
    • As a general rule, leave the upper most header. That is, if you remove the finishes and find that framing is riding on an intermediate header, and if you are worried about leaving the top plate unsupported by demolishing that header and if it is not feasible to transfer the potential load from below to above the element itself, then you would install temporary posts on each side of the work and to be extra safe you would put temp posts directly below at each level of your home down to the foundation (which may take selective demolish of the ceiling finishes to brace to the underside of the subfloor above), and then you would delete the existing wall and reuse or replace a header of the same design directly beneath the top plate with new bearing elements of the same design as previously removed.
  3. To address the framing element requirements (header, king, jack): there are three scenarios:

    • If the wall is structural; this depends on the load, and you have not provided the information I would need to offer a layman's safety factor answer.
    • If the wall is an interior partition not serving any structural function, you only need the minimum sufficient material to fasten and support your finishes.
    • If you are doing this work under a permit and subject to inspection and local code, or if at any time you are concerned about liability for deficiencies of the work, you will want to revise your post with the exact details of your jurisdiction, type of building, type of occupancy, building elements affected by the work, and any other technical details that come into play. First, you would consult with your jurisdiction's building department to see if they have any technical memos on the subject, then you should engage a designer as needed.

The important point I'm trying to get across is that you should only proceed if you know what you are doing and you are willing to take the risk even if you know what you are doing. Also, if you're not the owner, check with your landlord first.

Good luck @dabi!

It's almost surely possible but how much will you have to modify? Let's assume a structural header is required.

If the header is already high enough, nothing might be required, just remove cripples. If the header is not high enough you may still be able to do this. You might raise a header into the attic and the use hangers to support any beams. Supporting posts would need to be installed to support the new header.

For the first question - yes you can remove that for sure, from a structural point of view. You obviously want to remove drywall and make sure there are no electrical, plumbing or air vents going through.

The second question is way too broad. There are for sure load bearing components there and there is absolutely no reason to wonder "what if" until you figure out what is load bearing. Sometimes at that section of a house it is - everything.

With an engineer and lots of money you can remove any wall you want. The way to remove walls below the ceiling is to add supporting beams in the attic. These beams need to rest on something solid, like a wall on either side of the door opening. The span and size of the beam will depend on the distance between such supports. You need to have a better understanding of the attic space structure.
