Structured Cabling Permit Requirements in Jefferson County, Alabama

Structured cabling and data network installations in Jefferson County, Alabama—home to Birmingham and the state's largest business district—operate under Alabama's complex licensing framework. The state requires different licenses depending on the specific type of low voltage work, making it essential for contractors to understand which boards oversee their scope of work.

Quick Answer: Do You Need a Permit?
