In the U.S. one out of five people -- about 80 million -- live in some type of multifamily building. These structures are often referred to as "multi-unit housing" or "multi-housing" and include:

Example of Mid-rise Apartments or Condos
  • Attached townhouses
  • Low-rise apartments and condos
  • Mid-rise apartments and condos
  • High-rise apartments and condos

Multifamily buildings pose unique indoor air quality (IAQ) challenges because pollutants may move from unit to unit and residents have limited ability to make changes to the building structure itself.
