How should an inspector respond regarding a leaning retaining wall that shows no signs of damage or cracks?

The stance that a leaning retaining wall should be monitored, with the possibility of requiring a specialist's assessment, balances safety with the understanding that structural issues can develop over time. While the wall currently shows no signs of damage or cracks, the lean itself could indicate a potential problem, such as inadequate drainage, soil erosion, or shifting soil conditions.

Monitoring the wall allows for close observation over time to determine if its condition worsens, which would necessitate further action. By suggesting that a specialist might be needed, the response acknowledges the complexity of retaining walls and the expertise required to evaluate potential risks accurately. This approach ensures that the integrity of the wall can be assessed more thoroughly while ensuring homeowner safety.

The other perspectives imply either immediate action, which might be unnecessary, or a lack of potential risk, which could overlook significant future consequences.
