Overview of Florida Building Code and Standards
Between 1989 and 1995 the former Department of Community Affairs (now within the Florida Department of Business and Professional Regulation - DBPR) developed standards for radon resistant new construction and the mitigation of radon in existing structures. The standards for radon resistant new construction are divided into two categories: residential and large building. The residential standard is for single family homes and duplexes. The large building standard applies to all other construction. The standards are applied according to the DBPR Radon Protection Maps. These maps identify areas in the state where additional radon resistant construction features in new construction are recommended. Currently these standards are voluntary. It would take a majority of the building permit issuing agencies in any county to adopt them for the standards to become a required code within that county.
All mitigators are required to follow the mitigation standards as a condition of their radon mitigation certificate.
