What does a fire marshal do? Responsibilities, state and local roles, and how to become one

A fire marshal is the official responsible for enforcing the fire code in a jurisdiction: inspecting buildings, reviewing plans, investigating fires, and running the fire prevention programs that keep them from happening. The title covers a range of jobs. A state fire marshal runs an agency with statewide authority; a city or county fire marshal runs a fire prevention bureau inside the fire department; in a small town the fire marshal may be one person who does all of it. This guide covers what fire marshals do, how the state and local roles differ, the law enforcement side of the job, and how people become one.

What is a fire marshal?

The fire marshal is the Authority Having Jurisdiction, or AHJ, for fire protection in most of the United States. Where the fire chief commands suppression, the fire marshal commands prevention: the code that says a building needs a sprinkler system, the inspection that checks the system is maintained, the investigation that finds out why a fire started. The spelling is one L. "Marshall" is a surname; the office is the fire marshal.

A fire marshal's responsibilities

Responsibility	What it involves
Fire code enforcement	Applying the adopted fire code and NFPA standards to existing buildings; issuing citations and orders; following up on corrections
Fire and life safety inspections	Inspecting occupancies on a schedule set by risk: annual for many commercial buildings, more often for assembly, schools, and healthcare; reviewing the contractor's inspection reports for the building's systems
Plan review and permits	Reviewing sprinkler, alarm, and suppression system designs before construction; issuing permits for hot work, fireworks, hazardous materials, tents, and events
Acceptance testing	Witnessing the tests that put a new system into service and signing off on the certificate of occupancy
Fire investigation	Determining origin and cause after a fire; where arson is suspected, building the criminal case
Public education	School programs, smoke alarm campaigns, business outreach, Fire Prevention Week
Records and data	Maintaining inspection, permit, and incident records; reporting fire data to the state and to the national incident reporting system

State fire marshal and local fire marshal

The state fire marshal's office is a state agency, often within the department of public safety or insurance, with authority over the state fire code, licensing of fire protection contractors and technicians in states that license them, investigation of major fires, and inspection of state-owned and certain regulated buildings such as schools, hospitals, and care facilities. Many states also run the fire incident reporting system and the fire academy from there.

The local fire marshal works for a city, county, or fire district, usually as the head of the fire department's fire prevention bureau, with a staff of fire inspectors and investigators sized to the jurisdiction. Local fire marshals do the routine building inspections, the plan reviews, and the permits, and they are the AHJ a fire protection contractor deals with day to day. Where a jurisdiction has no fire marshal, the state office or the county fills the role.

Do fire marshals carry guns?

It depends on the jurisdiction and the job. Fire investigation can be a criminal matter, and in many states fire marshals and their investigators are sworn peace officers with arrest authority who carry firearms, attend a police academy, and work arson cases alongside detectives and prosecutors. In other jurisdictions the fire marshal is a civilian code official who inspects and enforces but does not investigate crimes, and the arson work goes to police or the state fire marshal's investigators. The badge and the sidearm belong to the investigative role, not to the title.

How to become a fire marshal

Most fire marshals come up through the fire service, but the path runs through inspection and investigation rather than suppression alone.

Step	What it usually takes
Firefighter or fire inspector	Fire academy and state firefighter certification, or entry as a civilian inspector; a fire science associate degree helps and is required in some departments
Fire inspector certification	International Code Council Fire Inspector I and II, or NFPA Certified Fire Inspector I and II; state fire inspector certification where the state issues one
Plans examiner and investigator credentials	ICC Fire Plans Examiner; for investigation, the International Association of Arson Investigators Certified Fire Investigator or NFPA 1033 qualification, plus peace officer standards where the role is sworn
Fire marshal	Appointment by the fire chief, city, county, or governor, typically after years in the prevention bureau; a bachelor's degree in fire science, public administration, or engineering is common at the state level

Continuing education never stops. The fire code and the NFPA standards revise on their published cycles, commonly every three to five years, each jurisdiction decides which edition it adopts, each new edition changes what an inspector looks for, and the credentials above require continuing education to renew.

Working with the fire marshal

For a building owner or a fire protection contractor, the fire marshal is the reader of every inspection report. The report that helps a fire marshal is the one that names the system, the standard and edition, the interval, the result, and the deficiency with its severity, so the inspector can see compliance without reconstructing it. The fire department versus contractor inspection article covers where the two inspections meet, and the deficiencies and impairments article covers the classification the fire marshal expects.

Common questions

Is a fire marshal a firefighter?

Often, by background. The job itself is inspection, enforcement, and investigation rather than fire suppression, and some fire marshals and inspectors are civilians.

Can a fire marshal shut down a building?

Yes. The fire code gives the AHJ authority to order a building or an event closed when conditions are dangerous to life, and to require a fire watch while a fire protection system is impaired.

How often does the fire marshal inspect a business?

It varies by jurisdiction and occupancy. Annual inspections are common for commercial buildings; higher-risk occupancies see the inspector more often, and small low-risk businesses less.
