Indiana Fire Sprinkler Contractor License Requirements (2026)

Indiana does NOT issue a statewide fire sprinkler contractor license. The Indiana Department of Homeland Security (IDHS) State Fire Marshal Division regulates fire safety statewide under IC 22-12 and IC 22-13 and performs centralized plan review for fire protection systems through the Plan Review and Inspections Section, but it does not require a state-issued contractor license for water-based automatic sprinkler and standpipe work. Instead, contractor licensing is left to local jurisdictions: most major Indiana cities (Indianapolis, Fort Wayne, Evansville, South Bend, Bloomington) and many counties require a local fire protection contractor license, plus NICET Level III in Water-Based Systems Layout for the responsible designer. Non-water suppression systems (CO2, dry chemical, halon) DO require IDHS technician certification under 675 IAC 22-2.

The Licensing Authority

Licensing for this trade is governed by Indianapolis Department of Business and Neighborhood Services — City of Indianapolis / Marion County (BNS), the agency that issues and regulates the credential under Revised Code of the Consolidated City and County, Chapter 875 (Contractors) and Chapter 871 (Electrical). BNS issues municipal contractor, electrical, and HVAC licenses for Indianapolis and Marion County. Indiana has no state license for these trades, so BNS is the dominant licensing authority for Central Indiana.

Phone: (317) 327-8700

Baseline Eligibility

Eligibility begins with two baseline checks: the applicant must be 18 or older and must provide a valid Social Security Number. No Indiana residency requirement. Out-of-state entities must register with the Indiana Secretary of State.

Good moral character

IDHS reviews each technician applicant for non-water suppression certification. Local AHJs perform their own fitness reviews for contractor licenses.

Background investigation

Mandatory disclosure of criminal history for IDHS technician certification.

Experience and Education Requirements

The cited source set does not publish a fixed year-based experience threshold for this credential. The controlling requirement is Indiana does not impose a state experience requirement for water-based fire sprinkler contractors. NICET Level III in Water-Based Systems Layout is the de facto requirement at most local AHJs and at the IDHS plan review desk.

Accepted proof of experience or eligibility

NICET Water-Based Systems Layout Level III certification card
Local AHJ contractor license (Indianapolis, Fort Wayne, etc.)
Resume describing past fire sprinkler projects

Education substitution

A B.S. in Fire Protection Engineering and Indiana PE license substitutes for NICET on stamped designs.

The Licensing Examination

NICET (for water-based work — no IDHS exam) or the Indiana Department of Homeland Security (for non-water suppression technician certification under 675 IAC 22-2). administers the required examination. Each part below must be passed before the license will issue:

NICET Water-Based Systems Layout Level III (de facto requirement, no IDHS exam) — 100 questions, 180 minutes, passing score 70%
IDHS non-water suppression technician examination (only required for CO2, dry chemical, halon work) — 50 questions, 120 minutes, passing score 70%

Examination fee: NICET exam fees paid directly to NICET. IDHS non-water technician fee is approximately $50.

Retake policy: NICET allows retakes after a 30-day waiting period.

Financial Security and Insurance

No statewide contractor license surety bond is required for this credential in the cited sources. Project-specific, permit, or public-works bonds may still apply, so confirm bonding before bidding a given job.

General liability

Indiana does not impose a state-level GL minimum for water-based fire sprinkler contractors, but local AHJ contractor licenses typically require $500,000–$1,000,000 GL.

Workers' compensation

Workers' compensation insurance is mandatory in Indiana for any employer with one or more employees under IC 22-3.

Additional financial requirements

No state-level financial statement requirement.

Fee Schedule

Fee	Amount
Application (non-refundable)	No separate state fee
Initial license	No separate state fee
Renewal cycle varies by jurisdiction	No separate state fee

License Renewal

The Indiana Fire Protection Contractor (Department of Homeland Security — State Fire Marshal Division) + Local AHJ Permits must be renewed every year. A standalone statewide renewal fee is not published in the cited record. Local AHJ contractor licenses each renew on their own schedule. Track each jurisdiction independently.

Continuing education: No state CE requirement. Local AHJs may impose their own CE expectations. The NICET certification must remain current via NICET's recertification cycle.

Reciprocity Map

Indiana grants no NASCLA reciprocity for this classification.

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

Because Indiana has no statewide license, reciprocity is not relevant at the state level. Local AHJ licenses (e.g., Indianapolis, Fort Wayne) generally do not reciprocate; each city issues its own contractor card. NICET certification is portable and accepted by every Indiana AHJ.

The Licensing Roadmap

Earn NICET Level III in Water-Based Systems Layout. Indiana AHJs and the IDHS plan review desk universally expect NICET Level III for the responsible layout designer.
Register the company with the Indiana Secretary of State. Out-of-state entities must register and appoint a registered agent.
Obtain local AHJ contractor licenses. Indianapolis, Fort Wayne, Evansville, South Bend, Bloomington, and many counties issue their own fire protection contractor licenses. Each must be obtained for work in that jurisdiction.
Bind general liability and Indiana workers compensation. Bind GL ($500k–$1M minimum at most local AHJs) and Indiana workers compensation.
Submit fire sprinkler plans to IDHS for centralized plan review. IDHS State Fire Marshal Division performs centralized plan review for fire protection systems statewide under the Indiana Building Code and Indiana Fire Code.
Coordinate acceptance testing with the local AHJ. Each project requires final acceptance testing per NFPA 13 chapter 25 by the local fire marshal.
Obtain IDHS non-water suppression technician certification (if applicable). CO2, dry chemical, halon, and other non-water suppression work requires individual IDHS technician certification under 675 IAC 22-2.

Common Application Pitfalls

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

Assuming a state license exists

There is no Indiana statewide fire sprinkler contractor license for water-based work. Out-of-state contractors waste time searching for one; the correct path is local AHJ licenses plus IDHS plan review.

One local license treated as universal

Each Indiana city/county issues its own contractor license. An Indianapolis license does not authorize work in Fort Wayne or Evansville.

Skipping IDHS plan review

IDHS performs centralized plan review for fire protection systems statewide. Submitting only to local building counters delays approvals and triggers field rejections.

Missing non-water technician certification

CO2, dry chemical, halon, and non-water suppression work requires individual IDHS technician certification under 675 IAC 22-2. Performing this work without certification is a violation.

No NICET on staff

IDHS plan reviewers and local AHJs expect NICET Level III stamped layouts even though no statute mandates it. Plans submitted without NICET layout credentials get rejected.

Before Filing: A Checklist

Have each of the following squared away before the packet goes to BNS:

☐ NICET Water-Based Systems Layout Level III
☐ Indiana Secretary of State registration (out-of-state)
☐ Local AHJ contractor licenses for each jurisdiction worked
☐ General liability and Indiana workers compensation certificates
☐ IDHS non-water suppression technician certification (if doing CO2/halon/dry chemical)
☐ IDHS centralized plan review approval per project
☐ Local AHJ acceptance testing per project
