What considerations should be made when determining the structural integrity of load-bearing walls in a house?

When determining the structural integrity of load-bearing walls in a house, considerations should include the materials used, the wall's design and construction, any previous modifications or damage, as well as the overall weight and distribution of loads on the wall. Consulting with a structural engineer or building inspector can help assess the wall's ability to support the intended loads and ensure the safety and stability of the structure.
