Code Check - Home of books, e-books, and illustrations for building, plumbing, electrical, and mechanical codes
Since 1995, our popular field guides to building codes have been helping builders, inspectors, designers, and homeowners navigate the maze of construction codes.
Our latest offerings are below.

The most up to date selection of the Code Check Illustration library. Many new and updated illustrations.
Code Check Complete 3rd edition is at the printer and will arrive soon. It has been extensively updated and expanded. It is a complete update of all the Code Check material to the latest editions of the codes.
The illustrations from this new book are available now in our new illustrations package, along with selected illustrations from our earlier editions. There are a total of 359 illustrations, and a list of them can be viewed here. Over half of the illustrations are new or updated. The illustrations are jpg files suitable for insertion into inspection reports, building department handouts, and educational presentations. The price for this new package will be $199.95, though for a limited time we are offering it for only 149.95 (the same price as the previous collection of illustrations).
The illustrations package does not include the text from the Code Check books – only the illustrations. It is available as an instant download, in zip file format.
Only $149.95 (Less than 50 cents per illustration!)
Code Check 9th Edition (Combo)
Our most popular book is designed for “combination inspectors” and covers building, plumbing, mechanical, and electrical systems. It is based on the most-used codes today - the 2018 IRC, UPC, UMC, & the 2017 NEC. It includes explanations of code changes from previous code cycles so it can also be used in areas still using 2015 model codes.
