Under what condition do you not need to access a crawl space?

Accessing a crawl space is generally not required when the height is 24 inches or more because this significant clearance allows for sufficient observation and inspection from outside the crawl space without needing to enter. A crawl space that is at least 24 inches high provides an opportunity for inspectors to assess conditions for termites or other structural issues by using tools or cameras from above, thus making it safer and easier than accessing a confined space directly.

In contrast, when the soil is too dry, it does not eliminate the potential for pest activity, thus necessitating inspection. Similarly, the absence of visible pests does not guarantee that infestations are not present, as termites can often live unnoticed in hidden areas. Additionally, temperatures below freezing do not prevent access; rather, they can affect the behavior of many pests, but inspections are still important regardless of external temperatures.
