Code Check books are the most widely-used reference series for information on building, plumbing, mechanical, and electrical codes in the United States. Each book is an illustrated guide to the most commonly used code sections.  They are used by building inspectors, home inspectors, contractors, do-it-yourselfers and homeowners.

New codes are issued every three years. Each Code Check edition is based on specific sets of codes and includes summaries of changes from the prior edition of codes.

With over 1.4 million copies sold since 1995, Code Check is the leader in navigating and understanding the voluminous, complex and sometimes tedious world of the codes.
