Determining Load Bearing Walls

To determine if the wall is a bearing wall, Tom suggests descending into the basement or attic to see in which direction the beams are heading.

If the wall is parallel to the beam, it is probably not bearing capacity. If the wall is vertical, it will probably support the load. (Determining Load Bearing Walls)

How to Tell If a Wall Is Load-Bearing

If you have a modification plan that involves removing or modifying the wall, determine if the wall is load-bearing.

All parts of the removed load-bearing wall must be replaced with appropriate structural supports such as beams and columns to carry the same load carried by the wall.

You should consult with an architect, such as a carpenter, architect, or structural engineer, to see if the wall is bearing capacity, but there are some clues you can check to get a preliminary answer. And you can do that without removing plaster and other invasive means.

Is the Wall Parallel or Perpendicular to Joists?

If the wall is a partial wall, that is, if it is stopped in front of an adjacent wall, it may or may not be loaded. 

For example, the builder may have installed a microram beam to carry the load up through the opening. Therefore, it cannot be assumed that the partial wall is a partition wall.

Is an Exterior Wall Load-Bearing?

The outer wall is the wall that forms the footprint around or outside the house. In most cases, the outer wall is loaded.

If there are windows or doors, the wall will contain beams or headboards that run above the openings. The poles on both sides of the opening support the beam.

Houses rarely have the full span of a non-load-bearing exterior wall. It is possible to build a house this way, but it comes with high financial costs.

Often, homes with no apparently supporting exterior walls are supported in the form of steel or wooden columns between the windows.

It is easy to overlook the fact that the substantive pillars are placed, as the windows and the outside scenery enjoy visual priorities.

Is a Masonry Wall Load-Bearing?

Masonry walls are likely to be loaded because they are a solid, substantive and very strong building material. However, masonry walls may or may not carry cargo.

The location of the masonry can indicate its capacity (for example, is it outside?).

A type of masonry called cladding of manufactured stones cannot withstand the load. As the name implies, it is a decorative layer, very light and tends to crumble under stress.

Foundation walls, commonly constructed of masonry materials, are naturally bearing because their main function is to support the weight of the house.
