Question 1

A home inspector observes horizontal cracks in a poured concrete foundation wall. What is the most likely cause?

Accepted Answer

Lateral soil pressure or hydrostatic pressure pushing inward

Answer

Horizontal cracks in foundation walls typically indicate lateral pressure from soil or water pushing against the wall, which is a serious structural concern.

Question 2

Which type of beam is identified by its tapered flange and is commonly used in residential floor framing?

Accepted Answer

American Standard (S-shape) beam

Answer

American Standard beams have tapered flanges, distinguishing them from wide flange beams which have parallel flanges.

Question 3

When inspecting floor joists, a home inspector finds that a joist has been notched at mid-span. What concern does this raise?

Accepted Answer

Notching at mid-span significantly reduces the joist's bending strength

Answer

Mid-span notching is the most critical location because bending stress is highest there, and any reduction in depth significantly weakens the joist.

Question 4

An inspector notices that a ridge board in an attic has a noticeable sag. What structural issue does this most likely indicate?

Accepted Answer

The ridge board is undersized or rafters are lacking proper collar ties

Answer

A sagging ridge board indicates that the roof framing lacks adequate support, often because the ridge is undersized or collar ties/rafter ties are missing.

Question 5

What does the term 'bearing wall' mean in residential construction?

Accepted Answer

A wall that transfers loads from above down to the foundation

Answer

A bearing wall supports the weight of floors, roofs, or other walls above it and transfers those loads to the foundation.
