Load-Bearing Wall
Affiliate link — we may earn a commissionA load-bearing wall carries weight from the structure above it down to the foundation. Exterior walls are almost always load-bearing. Interior walls that run perpendicular to floor joists and sit directly above a beam or foundation wall are usually load-bearing. Interior walls that run parallel to the joists are usually partition walls (non-load-bearing) that can be removed without structural consequence. Identifying which walls are load-bearing requires checking the joist direction in the attic or basement and tracing the load path from the roof down. When in doubt, hire a structural engineer.
Why It Matters
Removing or cutting a large opening in a load-bearing wall without adding a properly sized header or beam transfers the load to the drywall, floor, or nothing at all. Ceilings sag, floors dip, doors stop closing, and in worst cases the roof structure shifts. This is a structural issue, not a cosmetic one. Always verify before you swing a recip saw.
