No, Indiana permits flamethrower ownership without state-level restrictions, but local ordinances—particularly in municipalities like Indianapolis—may impose prohibitions or licensing requirements. Federal regulations under the ATF’s National Firearms Act do not classify flamethrowers as firearms, yet their use in public spaces or near structures could trigger local nuisance or fire safety codes. Recent 2026 draft amendments to the Indiana Fire Prevention Code propose stricter guidelines for “incendiary devices,” signaling potential future compliance obligations.
Key Regulations for Owning a Flamethrower in Indiana
- Local Bans: Cities such as Indianapolis and Fort Wayne enforce municipal codes prohibiting the discharge of flamethrowers within city limits, with penalties up to $5,000 for violations. The Indianapolis Municipal Code § 104-107 explicitly restricts “open flame devices” in public areas.
- Permit Requirements: While state law does not mandate permits, the Indiana Department of Homeland Security (IDHS) may require a Fireworks Permit for commercial or large-scale use, per Indiana Code 22-11-14-12.
- Federal Oversight: The ATF classifies flamethrowers as “destructive devices” if modified to exceed 1/4 ounce of incendiary agent per shot, triggering registration under 26 U.S.C. § 5845(f). Unregistered possession risks federal prosecution.
Compliance Note: Prospective owners must verify county-specific ordinances, as rural jurisdictions like St. Joseph County lack explicit bans but may enforce zoning laws restricting storage or use. Consult the Indiana Fire Marshal’s Office for 2026 updates to IC 22-11-14, which may expand regulatory scope.
