inspection
Crawlspaces should be inspected periodically.

As with any structure, long-term performance of a raised floor system requires regular building inspections and maintenance. Building codes require access to all underfloor spaces, with a minimum opening of 18″ by 24″ through a floor, or 16″ by 24″ through a perimeter wall.

The crawlspace should be inspected periodically to check for excessive moisture conditions from leaky plumbing, HVAC ducts, or standing water. The crawlspace should also be inspected periodically for the presence of damaging pests. Needed corrective actions or repairs should be made promptly to avoid problems related to moisture or pests.
