Louisiana contractor licensing is among the most-searched state licensing topics. This guide sets out what the official Louisiana pages say about contractor and plumbing licensing, quoting only facts our editor verified, so you can plan your application with confidence.
Below, the guide works through each trade in turn. Inside each section the facts are grouped by topic: who issues the license, the license levels, experience, the exam, fees and renewal. Each one is quoted from an official Louisiana page and linked. Where we haven't verified something, we say so and point you to the board.
A practical tip: write down which license you actually need before you compare fees or exams. Contractor licenses (for businesses that bid and contract work) and individual trade licenses (for the person doing the work) often have different requirements, and the scope label on each fact tells you which one it belongs to.
Check a Louisiana license: we don't hold a bulk license file for Louisiana, so use the board's own search, linked from Louisiana licensing board website.

Before you apply: a practical checklist
- Confirm which license you need. Is it a contractor (business) license, an individual trade license, or both? The scope label on each fact above tells you which one it describes.
- Collect proof of experience early. Boards usually want employer-signed records, and gathering them takes longer than people expect.
- Read the exam information on the official page before you book: provider, reference books allowed, and how retakes work.
- Budget for every fee, not just the application. Exam, license and renewal fees are often separate.
- Check local rules. Cities and counties can add their own registration or permit requirements.
- Keep your renewal date and any continuing education in your calendar once you're licensed.
