If that same wall is a loadbearing wall, the maximum size hole allowed to be drilled or notched from the wall studs is 25% of the 2"x4", or 7/8". If more than the maximum amount is removed from the wall studs, the use of approved stud shoes, per exception 2 noted above, would be required to reinforce the wall studs.
There is no hard and fast rule, but the width of opening would likely be limited by economic factors. The wall is load bearing, so the lintel must span across the opening and be stiff enough so that deflection is limited to L/600 or thereabouts, to prevent excessive cracking in the masonry above.
Drilling into a load-bearing wall can weaken the structure of the building and potentially cause a collapse or damage. It is essential to identify whether a wall is load-bearing before drilling.
The short answer is, yes. In most homes, you can remove any portion of a load-bearing wall.
Maximum depth - 25% of stud width: Maximum depth - 40% of stud width: 2" x 4" = maximum7/8" notch. 2" x 6" = maximum 1-3/8" notch. BORED HOLES Maximum size hole = 40% of stud width: 2" x 4" = max. 1-7/16" diameter hole.

Generally, a single 2x4 can support several thousand pounds of compressive load in the direction of its length. However, three 2x4s (especially if nailed together) will not triple this load-bearing capacity.
The general rule for cutting holes in a load bearing wall is that the diameter of the hole cannot exceed 1/3 the width of the stud.
Any stud shall be permitted to be bored or drilled, provided that the diameter of the resulting hole is not more than 60 percent of the stud depth width, the edge of the hole is not more less than 5/8 inch (16 mm) to from the edge of the stud, and the hole is not located in the same section as a cut or notch.
Because these structural, weight-sustaining elements of your home's framework are vital to the integrity of your house, they can't be removed without installing a replacement support system (beam, post, column, etc.) first.
It is worth remembering that most load-bearing walls already have a traditional hinged door installed in them, so it is possible to create an opening and install a door in a load-bearing wall. In most cases a 'header' will be installed above the door.
A: There are various techniques available for widening a doorway on a load-bearing wall. These include removing the existing door frame and installing a wider one, expanding the existing door opening, or creating a new opening adjacent to the existing one.
The Intertek-listed LPB/WPPS 60-01 2x6 exterior load-bearing wall assembly helps meet these demands and achieves three major objectives: fire code compliance, sound reduction and higher R-values than most 2x4 assemblies.
A load-bearing wall shoulders the entire weight of your home. If an opening is created and the wall is unable to support the load effectively, your house will need an alternative source of support. This usually means installing columns or a support beam to redistribute the weight.

On average, the price of a 20 ft lvl beam can range from $150 to $300. It is recommended to check with us for specific pricing.
Walls that run perpendicular to the joists are load-bearing walls. Walls that are parallel to the joists rarely are, but sometimes a bearing wall will be aligned directly under a single joist. If purlin bracing is attached to the top of a wall or is supported by a wall, it's a load-bearing wall.
The average cost to remove a load-bearing wall is $5,700 , but the price ranges from $1,400 for a wall in a single-story home to upward of $10,000 for a wall in a multi-story home. Removing a load-bearing wall requires serious structural considerations, and you'll need to hire the right pros.
When cutting into a load-bearing wall, it's essential to redistribute the load properly. This involves installing a header beam to transfer the weight to the sides of the new opening. Failure to provide adequate support can result in serious structural damage to your home.
Are there alternatives to removing a load-bearing wall? Yes, there are alternatives to completely removing a load-bearing wall. For example, you can create a wide opening in the wall without full removal, or you can install a pass-through window to maintain the open feel while keeping part of the structure intact.
The simple fact is that in most homes, you can remove as much of the load bearing wall as you want to. But you'll have to first consider what's inside the wall and how its weight will be redistributed once it is taken down.
Load bearing walls often provide support to floors. Removing a load bearing wall without considering the impact on the floor joists can weaken the load-bearing capacity of the floors above. This can lead to excessive deflection, sinking floors, or even structural failure.
Size standards, maximum moisture content, and nomenclature were agreed upon only as recently as 1964. The nominal 2×4 thus became the actual 1½ x 3½, imperceptibly, a fraction of an inch at a time. It was a 34 percent reduction in actual volume; as those in the trade would say, it's “selling air.”
