How to get a fire sprinkler license
There is no national fire sprinkler license. Each state decides, and the answer ranges from a full state license with NICET and exam requirements to no state license at all. Here is the general path, then every state we have verified.
Quick answer
- 42 jurisdictions verified to require a state license, certification or permit for sprinklers
- 25 of them name a NICET level in the official rule
- 15 list a state exam on the official source
- 4 verified with no statewide license (local rules)
The usual steps
- Find the issuing agency for the state. It is usually the State Fire Marshal, a contractor licensing board, or the electrical board. Each state below links to the agency.
- Pick the right license type. Most states separate the company (contractor or registration) from the individual (fitter, technician, designer or responsible managing employee).
- Get the qualifying certification. Where required, this is typically NICET Water-Based Systems Layout at a set level, or a PE license.
- Pass the state exam if the state has one (often a statutes-and-rules test).
- Apply with proof of experience, insurance and fees, then renew on the state's cycle.
- Check the city or county. Local AHJs can add their own licenses, registrations and permits on top of state rules.
