Load-Bearing Wall
A load-bearing wall is a structural wall that carries the weight of the structure above it, transferring loads from the roof, floors, and other building elements down to the foundation.
Load-bearing walls are critical structural elements that support the weight of everything above them—roof systems, upper floors, and additional loads. Unlike partition walls that simply divide space, removing or altering a load-bearing wall without proper support can cause catastrophic structural failure. These walls transfer vertical loads down through the foundation and into the ground.
Why It Matters in Remodeling
Identifying load-bearing walls is essential before any remodeling project. Removing a load-bearing wall requires installing alternative support systems like steel or LVL beams, proper headers, and columns or posts to carry the load. This work requires engineering calculations, building permits, and professional installation. Failure to properly support loads can result in sagging floors, cracked drywall, roof damage, or complete structural collapse.
Common Indicators
- Walls running perpendicular to floor joists above
- Exterior walls (nearly always load-bearing)
- Walls directly above basement support beams
- Center walls in homes with gable or hip roofs
- Walls with large headers above door openings
- Consult a structural engineer when in doubt—never assume a wall is non-load-bearing

LVL beam is an engineered lumber product manufactured by bonding thin wood veneers with adhesive under heat and pressure, creating exceptionally strong beams for long spans and heavy loads.
Framing
Framing is the process of constructing the structural skeleton of a building using dimensional lumber or engineered wood to create walls, floors, and roof systems.
Load Calculation
Load calculation is the engineering process of determining the forces acting on structural elements and designing adequate support to safely carry those loads.
