Washington State Patrol, State Fire Marshal's Office
To work as a sprinkler fitter in Washington, you need your own state certificate. It's yours, not your employer's, and it stays with you when you change jobs.
If you're starting with no experience, the usual path is a trainee job. You get hired by a licensed sprinkler contractor, apply for the training certificate, and get paid while you build hours. When your hours are in, you take the exam.
Washington issues three certificates for people doing the sprinkler work. The other two, the certificate of competency and the contractor license, matter later, if you ever run your own sprinkler business.
Where are you today?
Pick where you are to see your first steps. The full details follow.
You start by getting hired, not by applying for a license. A licensed sprinkler contractor can hire you as a trainee, and you then apply for the training certificate. It costs $100 and requires no previous work hours or exam.
You can also enter through a registered apprenticeship. Washington's registry lists 3 sprinkler fitter programs, with published starting rates from $17.78 to $30.19 an hour.
You need 4,000 hours on the job for the residential certificate, or 8,000 hours for the journey-level certificate. No more than 3,000 of the 8,000 journey-level hours can come from residential work. Those hours do not have to be earned through a registered apprenticeship.
The exam costs $150 per attempt and is administered by the State Fire Marshal's Office. You can take it up to three times a year, with at least 30 days between attempts.
If you pass on your first try, the total cost of your first certificate is $450. That's $100 to apply, $150 for the exam, and $200 for the certificate.
4,000 hours of sprinkler fitting qualifies you to test for the residential certificate; 8,000 for journey level. For journey level, no more than 3,000 of the hours can be residential work. The residential certificate covers residential systems only; on a commercial job, a residential fitter works as a trainee, under supervision.
The office decides whether your experience qualifies. You submit evidence of your hours on the form the office provides.
The exam costs $150 per attempt. You can take it up to three times a year, with at least 30 days between attempts. Once you pass, the certificate costs $200 and covers 2 years.
Washington does not publish a reciprocity list for these certificates.
Contact the Washington State Patrol, State Fire Marshal's Office and ask whether your license or your hours count toward a certificate here. Do it before you move.

Worth knowingThree routes lead in: the office's exam, a current NICET certificate in water-based system layout, or a professional engineer's license. The NICET certificate has to be at the level you apply for.

Held by the business · issued by the state
The contractor license itself has no work-hour requirement. The licensee must either hold a valid certificate of competency or employ a full-time holder. The application fee is $100.
Renewal is annual, with the fee based on contractor level.
Each renewal fee applies to the contractor level shown. The published renewal requirements do not list any additional work-hour requirement.
The state lists no license fee for this class: the published fees are the $100 application and the annual renewal.
A certificate of competency and the contractor license are not the same thing. The certificate of competency belongs to a person: it takes the office's exam, a NICET certificate, or an engineer's license. The contractor license belongs to the business, and a business qualifies by being, or employing full time, someone with that certificate.
Washington's registry lists 3 sprinkler fitter apprenticeships, with published starting rates of $17.78 to $30.19 an hour and journey rates of $39.50 to $71.89.
Three registered sprinkler fitter apprenticeships pay you while you earn these hours.
See all 3 programs and what they pay →The federal wage survey groups sprinkler fitters with plumbers, pipefitters, and steamfitters, so these figures cover that entire occupational group in Washington. Among those workers, half earn more than $38.96 an hour and half earn less. The survey puts the annual figure at $81,030. Apprentices and people decades into the trade are both in those numbers. Neither is a starting wage.
Washington gives these exams itself: the Washington State Patrol, State Fire Marshal's Office administers all three, at $150 per attempt. For the two fitter exams, you can test up to three times a year, with at least 30 days between attempts. The certificate of competency exam is passed at 80% or better. The trainee certificate and the contractor license have no exam. The NFPA standards these exams draw on are purchased separately. Use the official exam names when you book or call.

Washington counts hours, not years: 8,000 hours on the job for the journey-level certificate, or 4,000 for the residential one. At full-time hours that's roughly four years for journey level and two for residential. Your actual pace depends on how much you work, and the state publishes only the hours, not a timeline.
Yes. You get hired by a licensed sprinkler contractor and apply for the training certificate: $100, no hours, no exam. The hours you work from there are the experience.
$100 to apply, $150 per exam attempt, and $200 for the certificate itself, which covers 2 years. Pass on the first try and the first certificate comes to $450 all in. Renewing costs $200 every 2 years.
