A crawlspace is a shallow and uninhabitable area, usually between the soil and the first floor of the home. Crawlspace Inspections provide access to the electrical, plumbing and heating, ventilation and air conditioning (HVAC) systems located below the first floor. The following general guidelines are required in new homes:
- Minimum access opening is 18 inches by 24 inches.
- Minimum access opening if mechanical equipment (i.e. if an HVAC system is located in the crawlspace) is 30 inches by 30 inches.
- Minimum clearance between the soil and joists is 18 inches and 12 inches between the soil and beams.
- Minimum ventilation, every 150 square feet of floor space, requires a one square foot ventilation opening.
Water control and management in the crawlspace is essential for maintaining a house. The most common problem associated with wet crawlspaces is that moist conditions can lead to wood destroying fungus that deteriorates exposed framing. In addition, excessive moisture is a conducive condition that can lead to infestation of wood destroying insects, such as termites. In exceptional cases, water penetration into a crawlspace can lead to the undermining of the foundation.
