Check the building plans or structural drawings
See if the wall runs perpendicular to floor joists above
See if the wall is directly under a beam, post, or another wall
See if the wall is on the building’s exterior
See if the wall supports roof framing or ceiling joists
See if the wall continues through multiple floors in the same location
Look for doubled joists, beams, or headers above the wall
Check whether the wall is thicker than typical partition walls
Check for load-bearing walls in the basement or crawlspace below
Inspect for signs of structural transfer such as posts or columns nearby
Verify whether the wall is part of a central support line
Consult a licensed structural engineer or qualified contractor
