Existing law requires the commission to publish, or cause to be published, editions of the code in its entirety once every 3 years. Existing law requires the building standards and rules and regulations to impose substantially the same requirements as are contained in the most recent editions of specified international or uniform industry codes, including the International Residential Code of the International Code Council.
