INTERNATIONAL RESIDENTIAL CODE 2018

The International Residential Code 2018 (IRC), published by the International Code Council (ICC), is a comprehensive building standard referenced in the Florida Building Code and used in 1 Exam Prep’s contractor and residential exam preparation materials. This code outlines minimum regulations for one- and two-family dwellings up to three stories, covering structural design, plumbing, mechanical, electrical, and energy systems. It serves as a foundational reference for state and county contractor license exams, including the Florida Residential Contractor and Building Contractor examinations administered by the Construction Industry Licensing Board (CILB). 1 Exam Prep integrates the 2018 IRC into its structured online courses and book sets to align with state testing requirements and ensure compliance with current residential construction standards.
