The International Building Code provides builders in the
construction industry with safety rules and regulations. In other words,
a group of people got together and created a few rules to make the
buildings you occupy as safe as possible.

Most cities and counties throughout the United States
have Building and Safety Departments that use Building Inspectors to
enforce Building
Codes. I might have overused the word building in that last
sentence, but these rules are there to protect us and most of them fall
into the category of common sense.
Here's an example of one building code that has to do with variations in
your stair steps. To learn more about building codes, click on a few of
the links below.
Four Step Stairway Example 1: The bottom riser is 7 inches, the second
riser is 7 inches, the third riser is 7 inches, the fourth riser is 7
inches but the fifth riser is 7 1/2 inches. There is more than 3/8 of an
inch variation and this particular stairway wouldn't pass most building
inspections.
