Where do you start, and what are the best practices to search out the correct codes?
Start with your state - your state will adopt a national code. Most have adopted the international building code (IBC printed from the ICC) international code council. << History lesson: The international code has grown from the Building Code Council and Southern Building Code into the National presence it is today. >>
Next, Drill down to the local level by calling the CITY HALL of the area where you are working. Check with their building department and/or Development department.
Next check is the internet: search for the code they gave you as the adopted code on your favorite search drive Google, Yahoo, etc.
My favorite Code website listing all states codes is from Reed Construction Data http://www.reedconstructiondata.com/building-codes/ this web location tells you the state code and local adoptions plus the telephone and some web links to free codes (and they have been very accurate)!
The next major component is to check the local ordinances this again is with the local city hall/building inspection. The city’s web site will get you to their adopted amendments or code but it is best to find out what section they adopted, like California TITLE 24, etc.
Finally don’t forget to check what the local authority has adopted for their accessibility standards, ANSI, or some version. (Remember if federal monies are involved in your project you use the federal guidelines).
Good luck -John OUT.
