Ohio Unlawful Possession of Dangerous Ordnance Lawyer
Accused of Possessing Illegal Weapons?
Ohio’s dangerous ordnance statute covers two high-stakes allegations under the same section: (1) unlawful possession of dangerous ordnance, and (2) illegally manufacturing or processing explosives.
A charge under O.R.C. 2923.17 can put serious penalties and prison time on the table. These cases also tend to expand quickly once prosecutors start treating the situation as an explosives investigation—search warrants, lab testing, and aggressive felony charging decisions often follow.
At Patituce & Associates, we defend clients charged with serious weapons and violent crime allegations statewide, including cases where the State pushes for severe outcomes.

What the Law Says About Dangerous Ordnance & Explosives
O.R.C. 2923.17 is the Ohio statute prosecutors use for dangerous ordnance and explosives allegations. The statute covers two different offenses with very different levels of exposure. The first is a possession-based case. The second is an explosives manufacturing allegation that carries serious penalties and prison time.
Under this law, the State may charge:
- Unlawful possession of dangerous ordnance (O.R.C. 2923.17(A)) — prosecutors allege you knowingly acquired, had, carried, or used “dangerous ordnance” as Ohio defines that term.
- Illegally manufacturing or processing explosives (O.R.C. 2923.17(B)) — prosecutors allege you manufactured or processed an explosive in Ohio without first obtaining the required license, certificate of registration, or permit from the proper fire authority.
Defense strategy starts with identifying which subsection the State is relying on, then forcing proof on the specific elements and definitions the statute requires.

What Counts as “Dangerous Ordnance” in Ohio?
Ohio’s definition is broader than most people expect. “Dangerous ordnance” includes categories such as:
- Automatic or sawed-off firearms, zip-guns, and ballistic knives
- Explosive devices or incendiary devices
- Specified high explosives and blasting agents
- Military-type weapons (and ammunition) such as grenades, mines, bombs, and similar weapons designed and manufactured for military purposes
- Firearm mufflers/suppressors
- Combinations of parts intended to convert a device into dangerous ordnance (R.C. 2923.11(K))
Ohio law also lists several important exclusions — for example, certain sporting firearms, antiques/black powder items in lawful use, and inoperable/inert ordnance kept as a curio.
Exceptions, Permits, and “Legal Authority” Defenses
O.R.C. 2923.17 contains exceptions for certain government/law enforcement/military activities and for properly licensed federal importers/manufacturers/dealers in certain contexts.
Ohio also allows a license or temporary permit to acquire/possess/carry/use dangerous ordnance for specified legitimate purposes (e.g., contractors who regularly employ explosives; farmers for agricultural purposes; research/instruction; and other proper purposes in the issuing authority’s discretion).
For manufacturing/processing allegations under O.R.C. 2923.17(B), the central issue is often whether the person had the required authorization from a fire official or the State Fire Marshal before the State claims the conduct occurred.
How Patituce & Associates Can Help
If you've been accused of a dangerous ordnance or explosives offense in Ohio, we can help by:
- Intervening early to control exposure and prevent avoidable damage to your case
- Demanding proof of the exact O.R.C. 2923.17 subsection charged and the elements the State must establish
- Challenging key evidence (testing, chain of custody, witness claims, digital evidence)
- Litigating suppression issues when police conduct or warrant execution violated the rules
- Negotiating from strength and taking the case to trial when prosecutors won’t be reasonable
What the State Must Prove
Possession Case
To convict, prosecutors generally try to prove:
- You knowingly acquired/had/carried/used an item, and
- The item meets Ohio’s definition of dangerous ordnance
Manufacturing or Processing Explosives
To convict, prosecutors generally try to prove:
- You manufactured or processed an explosive in Ohio, and
- You did so without first obtaining the required license/certificate/permit from the proper fire authority
Common defense pressure points include:
- Whether the substance or device meets the statutory definitions and whether testing is reliable
- Whether the State can prove knowing possession or actual manufacturing/processing (not mere proximity or suspicion)
- Whether the alleged authorization/permit issue is being overstated or misapplied
- Search warrant and seizure issues (home searches, electronic devices, containers, vehicles)
Penalties for Dangerous Ordnance Charges
Unlawful Possession of Dangerous Ordnance (F5)
A violation of O.R.C. 2923.17(A) is a felony of the fifth degree.
- Prison range: 6–12 months (F5)
- Maximum fine: up to $2,500 (F5)
Illegally Manufacturing or Processing Explosives (F2)
A violation of R.C. 2923.17(B) is a felony of the second degree.
- Prison exposure: for many F2 offenses committed on/after March 22, 2019, Ohio uses an indefinite sentencing structure with a minimum term selected from 2–8 years and a maximum term determined by statute
- Maximum fine: up to $15,000 (F2)
In addition to prison and fines, these cases often involve forfeiture allegations, restrictive bond terms, no-contact/no-return orders (depending on the fact pattern), and serious professional and licensing consequences.
Defense Strategy in Dangerous Ordnance and Explosives Cases
Effective defense typically focuses on:
- Definition and testing disputes (what the item/substance legally is, and whether the State’s testing is sound)
- Knowledge and possession issues (who had control; whether the State can prove knowing possession)
- Authorization/permit defenses for the specific conduct alleged under R.C. 2923.17(B)
- Search and seizure litigation (warrant scope, probable cause, unlawful entry, overbroad device searches)
- Overcharging and leverage control (forcing the State into the correct subsection and correct theory)
