Check Out InterNACHI's Healthy Homes Inspector Certification Program

People in the North America spend about 70% of their lives inside their home, and almost 20% in a school or other commercial building. This suggests that the condition of a home is a primary factor in a person’s overall health. If your client’s home has defects, their health may be suffering, too.

Scientific evidence demonstrates a solid relationship between housing conditions and human health. Studies on the economic burden of specific defects in homes show costs rising into the billions of dollars annually. Defects in the home contribute to both poor health and the economic burdens on society at large.

The good news is that most home-based hazards are preventable. Not only can we help reduce health problems for homeowners and their families, but we can relieve the economic costs associated with poor housing, too, which also results in a positive return on the investment. And it all starts with inspecting the home. InterNACHI® recommends that an annual home inspection should be a part of a homeowner’s routine maintenance plan, because a healthy home provides a safe and healthy environment for its occupants.

Substandard housing has long been associated with a wide range of health hazards. In the 19th century, public health officials targeted poor sanitation, overcrowding, and inadequate ventilation to help reduce the spread of infectious diseases, as well as fire hazards.

A healthy home is:

  1. dry;
  2. clean;
  3. safe;
  4. pest-free;
  5. free of contaminants;
  6. well ventilated;
  7. well maintained; and
  8. thermally controlled.

Today, we use multiple strategies to maintain improved housing conditions, such as developing and enforcing construction standards and codes, and advocating for safe and healthy housing that’s also energy-efficient. You can be a part of this movement by joining InterNACHI’s Healthy Homes Inspector Program, which is primarily based upon housing in the United States and Canada.
