Utah Fire Sprinkler License Requirements

Utah’s S370 Fire Suppression Systems Contractor classification covers the layout, fabrication, and installation of fire-protection systems using water, steam, gas, or chemicals. It does not cover connecting to a potable sanitary-water supply, and it excludes fire-suppression systems in hoods above cooking appliances. The current DOPL application gives S370 applicants a choice: hold a B100 General Building Contractor license, or complete a federally approved apprentice program (or document two years under immediate supervision of a certified fire-sprinkler fitter) and pass the NITC STAR Fire Sprinkler Fitting Mastery examination or an equivalent DOPL-approved exam. DOPL contractor licensure is not the whole compliance picture: the State Fire Marshal separately regulates sprinkler inspection/testing and automatic fire-suppression concerns, while the project AHJ controls the applicable permit, plans, and inspection process.

Regulatory Body

Licensing for this trade is governed by Utah Division of Professional Licensing; Utah State Fire Marshal Office (DOPL / SFM), the agency that issues and regulates the credential under Utah Code Title 58, Chapter 55; Utah Admin. Code R156-55a; Utah Fire Prevention and Safety Act and State Fire Marshal rules. DOPL licenses S370 contractors. The State Fire Marshal regulates designated sprinkler inspection/testing and automatic-fire-suppression work. The state or local authority having jurisdiction (AHJ) administers project-specific fire/building approvals and inspections.

Eligibility Requirements

This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Check the current application for identification and tax-number requirements. DOPL does not publish an S370-specific Utah-residency requirement. Follow the current Contractor Application for entity registration, EIN, and sole-proprietor instructions.

Good moral character

The current Contractor Application requires disclosures concerning discipline, pending criminal matters, specified convictions, and financial responsibility. DOPL may request supporting records.

Background investigation

DOPL’s current contractor information says a fingerprint-based contractor background-check requirement begins January 1, 2027. Do not present it as a current 2026 S370 application requirement. State Fire Marshal programs have their own application rules where applicable.

Experience and Education

At least 2 years of For the S370 alternative to holding B100, complete a U.S. Department of Labor federally approved apprentice-training program or document two years of experience under the immediate supervision of a licensee who has obtained a fire-sprinkler-fitting certification. The current application also requires the NITC STAR Fire Sprinkler Fitting Mastery examination or a Division-approved equivalent. has to be evidenced and confirmed. Retain payroll, tax, project, or supervisor records, since the board may audit the experience claimed.

Accepted proof of experience or eligibility

Current Contractor Application with S370 selected
B100 General Building Contractor license, or apprentice-program completion / documentation of the required two years of immediate supervised experience
NITC STAR Fire Sprinkler Fitting Mastery examination result or DOPL-approved equivalent
25-hour approved specialty-contractor pre-licensure course completion
Utah entity registration where applicable and EIN/sole-proprietor records
Liability-insurance certificate naming DOPL as certificate holder
Workers’ compensation, Utah withholding-tax, and unemployment-insurance records when the company has employees, or a Workers’ Compensation Coverage Waiver when it does not
Separate State Fire Marshal applications, registrations, and insurance only for the fire-sprinkler inspection/testing or automatic-suppression services actually offered

Education substitution

The current 2026 S370 application does not support the former NICET Automatic Sprinkler System Layout Level III claim. Its stated alternative is a federally approved apprenticeship or two years of immediate supervised experience, plus the NITC STAR Fire Sprinkler Fitting Mastery examination (or DOPL-approved equivalent).

Exam Requirements

Testing provider or authority: National Inspection Testing and Certification Corporation (NITC), unless DOPL approves an equivalent. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

STAR Fire Sprinkler Fitting Mastery examination (or DOPL-approved equivalent) — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: The current DOPL S370 application identifies the NITC STAR examination or a Division-approved equivalent but does not publish a DOPL S370 exam fee, question count, duration, or passing score. Obtain current NITC/DOPL details before scheduling.

Retake policy: Use the current NITC or DOPL-approved-equivalent policy. DOPL’s contractor exam page does not list a separate S370 Business-and-Law or Pearson/Prometric trade examination.

Insurance and Bonds

No license surety bond is mandated statewide here under the cited sources, though project-specific or public-works bonding obligations can still attach to a given job.

General liability

DOPL’s current contractor announcement sets the all-contractor minimum at $1,000,000 per occurrence and $2,000,000 aggregate; the specialty-application page requires a certificate naming DOPL as certificate holder. The State Fire Marshal has separate insurance rules for its sprinkler inspection/testing and automatic-fire-suppression programs; do not substitute one program’s certificate for the other.

Workers' compensation

With employees, DOPL requires workers’ compensation, Utah withholding-tax, and unemployment-insurance documentation (or approved PEO documentation). Without employees, obtain the Utah Labor Commission Workers’ Compensation Coverage Waiver.

Additional financial requirements

The current specialty application does not impose a universal S370 surety bond. DOPL may require a bond after its financial-responsibility review under the statute and rule. State Fire Marshal concern programs have separate insurance and operational requirements.

Fee Schedule

Fee	Amount
Application	$175
Initial license	No separate amount recorded; confirm in the fee guidance
Renewal (every 2 years)	$128

Renewal and Continuing Education

The Utah S370 Fire Suppression Systems Contractor — Fire Sprinkler Scope must be renewed every 2 years. The fee to renew is presently $128. DOPL contractor licenses expire November 30 of odd-numbered years. Do not merge this cycle with separate State Fire Marshal certificates of registration or concern licenses, which use their own renewal rules.

Continuing education: Complete six approved CE hours each DOPL contractor licensing period: three core hours and three core or professional hours. DOPL says no more than three hours may be completed online.

Reciprocity

Utah grants no NASCLA reciprocity for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

DOPL’s current contractor process provides for endorsement when the applicant has held a similar active, good-standing out-of-state contractor license for at least one year and can show qualifying ownership continuity. It does not publish bilateral S370 reciprocity or a blanket S370 exam waiver. State Fire Marshal certificates are separate.

Step-by-Step Application Roadmap

Classify the entire project scope. Use S370 for the defined fire-protection-system scope. Arrange a P200 or P201 contractor for a potable sanitary-water connection, and use the appropriate separate pathway for hood suppression, electrical/fire-alarm work, inspection/testing, or other work outside S370.
Meet the S370-specific qualifier path. Either hold B100 General Building Contractor, or complete a federally approved apprentice program or document two years under immediate supervision of a certified fire-sprinkler fitter; then pass the NITC STAR Fire Sprinkler Fitting Mastery examination or an approved equivalent.
Complete the specialty-contractor prerequisites. Complete DOPL’s 25-hour approved specialty pre-licensure course and prepare the business, insurance, and employment/waiver records required by the current application.
File S370 with DOPL. Submit the current Contractor Application and current primary-classification application fee. Do not rely on stale S350, NICET III, four-year, or Pearson trade-exam instructions.
Add State Fire Marshal credentials when the service triggers them. Persons inspecting or testing automatic sprinkler systems require a State Fire Marshal certificate of registration. A business engaging in covered automatic fire-suppression-system work needs the appropriate State Fire Marshal concern license; verify the exact service class before contracting.
Obtain AHJ approvals for the actual project. Coordinate plans, permits, review, installation acceptance, and inspections with the authority having jurisdiction. State contractor licensing does not itself issue a project permit or approve a design.

Common Filing Mistakes

These are the recurring mistakes that most often delay or reject a Utah Fire Sprinkler application, based on the official instructions cited here.

Using S350 or a generic “fire sprinkler” classification

The current contractor application lists S370 Fire Suppression Systems Contractor. S350 is the HVAC classification, not the S370 sprinkler/suppression classification.

Relying on obsolete NICET III, four-year, foreman, Pearson, or DOPL trade-exam claims

The current S370 application specifies B100 or the apprenticeship/immediate-supervision path and the NITC STAR Fire Sprinkler Fitting Mastery examination (or an approved equivalent). It does not publish the stale requirements.

Treating DOPL S370 as the only credential

State Fire Marshal certification is separately required for sprinkler inspection/testing, and its automatic-fire-suppression concern program applies to covered suppression services.

Crossing the S370 scope boundary

S370 excludes potable sanitary-water connections and hood suppression. Use the appropriate plumbing or State Fire Marshal/specialty path rather than treating S370 as unrestricted fire-protection authority.

Skipping the actual AHJ

Permits, plan review, installation acceptance, and inspections remain project- and jurisdiction-specific.

Frequently Asked Questions

What is Utah’s fire-sprinkler contractor classification?

The relevant DOPL specialty classification is S370 Fire Suppression Systems Contractor, not S350. Its scope is layout, fabrication, and installation of fire-protection systems using water, steam, gas, or chemicals, subject to the listed exclusions.

Does Utah require NICET Level III for the S370 contractor qualifier?

The current March 2026 Contractor Application does not make the former NICET Level III claim. It requires B100, or a federally approved apprentice program/two years of immediate supervised experience with a certified fire-sprinkler fitter, plus the NITC STAR Fire Sprinkler Fitting Mastery examination or a DOPL-approved equivalent.

Can an S370 contractor connect a sprinkler system to potable water?

No. The S370 scope excludes a potable sanitary-water-supply connection; the rule says the S370 contractor may hire or subcontract a P200 or P201 contractor for that work.

Does DOPL S370 authorize sprinkler inspection and testing?

Do not assume so. The State Fire Marshal says persons engaged in automatic fire-sprinkler inspection and testing must hold its certificate of registration. That is separate from DOPL contractor licensure.

How does S370 renew?

DOPL contractor licenses expire on November 30 of odd-numbered years. The current DOPL renewal page lists a $128 contractor renewal fee and six approved CE hours per licensing period. State Fire Marshal registrations and concern licenses have separate, often annual, renewal rules.
