Load Bearing Walls Should Never be modified without First Architectural Review
By Mark J. Donovan
||Load bearing walls as the name suggests are walls that bear the weight of upper levels and the roof.
It is extremely important to never remove or modify load bearing walls without first seeking input from an architect or your local building inspector.
Removing or modifying a load bearing wall could lead to catastrophic failure of the home which in turn could endanger the lives of people in the home.
What are Load Bearing Walls?
In general any wall that runs perpendicular to floor joists and or roof rafters is a sure bet that it is probably a load bearing wall.
Gable end walls, which in certain cases do not have floor joists or roof rafters running perpendicular to them, are also load bearing.
|This said, your home’s exterior walls are typically load bearing walls. The reason for this is that exterior walls sit on the foundation walls and carry the load of upper levels, ceilings and roofs.
In addition to exterior walls acting as load bearing walls there are also many cases where interior walls are load bearing. Typically interior walls that run perpendicular and mid-span to floor joists or rafters are load bearing walls.
These types of load bearing interior walls transfer the weight of upper levels, roofs and ceilings down to the foundation walls or lally columns that are strategically placed in the basement.
Crossbracing can be identified in a home by looking for angled boards or metal rods/straps that start at the corner of a wall and run a portion of the length of the wall from top to bottom.
