Schools, hospitals, nursing homes, daycare centers, assisted living facilities, and state-owned buildings are typically required to conduct regular radon testing to protect vulnerable populations. Many commercial workplaces must also test to comply with employee safety regulations and workers’ compensation requirements. Penalties vary by state but can include substantial fines, facility closure, and liability for health claims. Insurance companies may deny coverage for facilities that haven’t conducted required testing. Even if not legally mandated, property managers and facility owners face significant liability exposure from employee or tenant health claims if dangerous levels are discovered without prior testing.
