It mandates that all new single-family and two-family residential constructions must incorporate a passive radon mitigation method as specified in appendix AF of the 2021 edition of the International Residential Code. This requirement will only apply to constructions that begin after the adoption of this regulation.

Additionally, the bill amends existing law to ensure that the provisions related to radon mitigation are applicable to all new single-family and two-family residential constructions in the state. This legislative change aims to enhance public health and safety by addressing radon exposure in residential environments.
