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.
