How to Build a Multifamily Radon Testing Program
With over 21 million multifamily housing units in United States and over 5 million Canadians living in multifamily homes, radon measurement professionals have a substantial opportunity for radon testing in this market segment. Measuring radon in large, multifamily buildings is far more complex than in single-family homes and yet it represents a way to scale business operations and reach a growing market.
Why should renters test for radon?
Although it’s not often the first factor considered by multifamily building owners and managers, knowing the radon levels in a dwelling is an important health consideration for all residents. Radon gas is the #1 leading cause of lung cancer in nonsmokers and the 2nd cause of lung cancer.
