About this course

Independent GCHS training

Each lesson has a dimensioned diagram, a glossary, 14 practice questions (20 in Lesson 15) and neural narration. Numbers were checked against at least two public sources that restate the 2021 IRC. Texas cities adopt their own code editions and local amendments, so always confirm the edition and amendments in force where the work is permitted. This is training, not a substitute for the adopted code.
