A crawl space, which in earlier years took the form of a dirt cellar, is a volume of air between the earth and a house’s main floor whose purpose is to keep the floor of the building raised up off of the ground and away from moisture.

To comply with the Building Code, a crawl space may not have an access door with stairs (although one without stairs is acceptable), hold any type of combustion appliance or be used as a bedroom or office.

Homes built in the 1970s and 80s and insulated to the standards of their time (R‑12 versus today’s R‑41) are energy-hungry beasts. Weak insulation points in houses from that era include the roof (attic), which is responsible for numerous uncontrolled air leaks causing significant heat loss. Continued
