Which building code should a contractor follow?

• A. Local code
• B. International Building Code
• C. Uniform Building Code
• D. National Building Code

Answer: (A)

The code you must follow is the one adopted by the local jurisdiction where the project is located. Local building departments choose and enforce a specific code, often with their own amendments, and these enforceable rules govern permit reviews, inspections, and compliance. Model codes like the International Building Code may be adopted by a jurisdiction, but only after local adoption; the Uniform Building Code is an older framework, and the National Building Code is not the standard used in most U.S. locations. So, sticking to the locally adopted code ensures you meet the legal requirements for that project site.
