foundation wall
brick overhang
if the foundation wall bows inwards and the brick wall above doesn't, a dangerously large brick overhang could develop (potentially leading to wall instability)
a one inch overhang is generally considered to be the maximum acceptable

Generated explanation

The illustration shows two brick walls meeting at a corner above foundation walls supported on a projecting footing. Along one side, the foundation wall bows inward while the brick wall above remains straight, creating excessive brick overhang. A dashed reference line along the base helps illustrate the foundation's inward displacement. The annotation identifies reduced support and potential wall instability, and states that a one inch overhang is generally considered the maximum acceptable.
