Dayton is the county seat of Montgomery County, and most serious criminal cases in the Miami Valley's largest county are decided in the Common Pleas courts building on North Perry Street. Misdemeanors, OVI charges and the opening stage of every felony are spread across six municipal courts: Dayton, Kettering, Miamisburg, Oakwood, Vandalia and the two-division Montgomery County Municipal Court. Felony cases are prosecuted by the elected Montgomery County Prosecuting Attorney, while city prosecutors and law directors handle the misdemeanor dockets in their own municipal courts. Adults who are not released after arrest are held by the Sheriff at the Montgomery County Jail on West Second Street in downtown Dayton.

Which court hears your case. The location of the offense decides the first court. Misdemeanors, OVI and traffic charges from inside Dayton go to Dayton Municipal Court. Kettering Municipal Court takes Kettering, Centerville, Moraine and Washington Township. Miamisburg Municipal Court covers Miamisburg, Germantown, West Carrollton and German and Miami townships. Oakwood Municipal Court hears cases from Oakwood. Vandalia Municipal Court serves Vandalia, Clayton, Englewood, Union and Butler, Harrison and Randolph townships. Montgomery County Municipal Court handles everything else, including Huber Heights, Trotwood, Riverside, Brookville and the townships not named above. Ordinance and traffic tickets written in Moraine or West Carrollton may instead go to that city's mayor's court, which has no jury; a defendant there can ask to move the case to the municipal court. A felony charge also opens in the municipal court for the place of arrest, which handles the initial appearance and any preliminary hearing. It moves to the Common Pleas Court, General Division, once a grand jury returns an indictment or the defendant agrees to proceed on a bill of information. Appeals go to Ohio's Second District Court of Appeals.

Where pretrial detainees are held. The Sheriff runs the Montgomery County Jail at 345 W. Second Street, a few blocks from the courts. Adults arrested by the Dayton Police, suburban departments, the Sheriff's deputies or the State Highway Patrol are booked there when they are not cited and released. People waiting on bond, on a hearing or on trial stay there, along with people serving local misdemeanor sentences. For custody status or bond questions, call the Sheriff's Office at (937) 225-4357. Youths are held separately at the Juvenile Justice Center.

Montgomery County has no county court. State law divides the whole county among municipal courts, so every address in the county falls inside one of them. Two cities also keep mayor's courts for local ordinance and traffic cases. The territories listed below come from the municipal court statute; the clerk can confirm which court a particular street belongs to.

Municipal courts

• Dayton Municipal Court — 301 W. Third Street, Dayton, OH 45402, (937) 333-4300. Covers the City of Dayton.
• Kettering Municipal Court — 2325 Wilmington Pike, Kettering, OH 45420, (937) 296-2461. Covers Kettering, Centerville, Moraine and Washington Township.
• Miamisburg Municipal Court — 10 N. First Street, Miamisburg, OH 45342, (937) 866-2203. Covers Miamisburg, Germantown, West Carrollton, German Township and Miami Township.
• Oakwood Municipal Court — 30 Park Avenue, Oakwood (Dayton), OH 45419, (937) 293-3058. Covers the City of Oakwood.
• Vandalia Municipal Court — 245 James E. Bohanan Memorial Drive, Vandalia, OH 45377, (937) 898-3996. Covers Vandalia, Clayton, Englewood, Union, and Butler, Harrison and Randolph townships.
• Montgomery County Municipal Court, Eastern Division — 6111 Taylorsville Road, Huber Heights, OH 45424, criminal and traffic (937) 496-7231.
• Montgomery County Municipal Court, Western Division — 875 E. Main Street, Trotwood, OH 45426 (moved from New Lebanon in 2023), criminal and traffic (937) 687-9099.

The two Montgomery County Municipal Court divisions share the territory not assigned to any city court. That includes Huber Heights, Trotwood, Riverside, Brookville, New Lebanon, Farmersville, Phillipsburg and the remaining townships. Your citation or bond slip names the division.

Mayor's courts

• Moraine Mayor's Court — Moraine city offices, 4200 Dryden Road, Moraine, OH 45439, (937) 535-1010.
• West Carrollton Mayor's Court — 300 E. Central Avenue, West Carrollton, OH 45449, (937) 859-8288.

A mayor's court decides ordinance and traffic cases without a jury. If a defendant requests a transfer, or the charge is beyond the mayor's court's authority, the case goes to the Kettering or Miamisburg Municipal Court.

Downtown Dayton holds most of the buildings a criminal defendant will need, all within walking distance of each other:

• Montgomery County Courts Building, 41 N. Perry Street. This is the Common Pleas General Division building, where felony arraignments, pretrials, plea hearings, trials and sentencings take place. Court administration also uses the Reibold Building at 114 S. Main Street.
• Dayton-Montgomery County Courts Building, 301 W. Third Street. This building houses Dayton Municipal Court, and the Prosecuting Attorney's main office is on its fifth floor.
• Juvenile Justice Center, 380 W. Second Street. This building holds the Juvenile Court and its detention center.
• Walter H. Rice Federal Building and U.S. Courthouse, 200 W. Second Street. Federal cases are heard here.

The suburban municipal courts are in Kettering, Miamisburg, Oakwood, Vandalia, Huber Heights and Trotwood. If you were cited in a suburb, do not assume your case is downtown. Check the court named on the ticket or bond slip, and plan for a security screening line at every building. Felony cases have an assigned Common Pleas judge, and the Clerk of Courts docket shows the judge's name and the next hearing.

1. Booking. After an arrest in Dayton or a suburb, the person is taken to the jail on West Second Street. Booking includes fingerprints, a photo, a records check, a property inventory and a medical screening. For many minor offenses, officers instead issue a citation with a court date and no trip to jail.
2. Bond. Many common charges have a preset bond under the municipal courts' bond schedules, and some people can post bond within hours. Otherwise a judge sets bond at the first appearance. Under the 2022 amendment to the Ohio Constitution, the judge must weigh public safety, the person's criminal record, the seriousness of the offense and the likelihood the person will return to court. The options are a recognizance bond (no money), a 10 percent deposit bond, or a cash or surety bond. Commercial bail bond companies operate legally in Dayton.
3. Initial appearance or arraignment. A jailed defendant usually sees a municipal judge or magistrate the next business day, often by video from the jail. The court reads the charge, appoints a lawyer if the person qualifies and decides release. On a misdemeanor, the defendant normally enters a plea at this hearing.
4. Preliminary hearing (felonies). The municipal court must hold this hearing within 10 consecutive days if the person is in jail, or 15 days if released, unless an indictment is returned first. In Montgomery County, many felony cases go straight to the grand jury, so the preliminary hearing never takes place.
5. Grand jury and Common Pleas arraignment. After an indictment, the defendant is arraigned at 41 N. Perry Street and pleads not guilty or guilty. The case is then assigned to a judge for pretrials.

Ohio's speedy-trial statute requires a felony trial within 270 days of arrest. Each day a defendant spends in jail on that charge counts as three days toward that limit. Delays caused or requested by the defense stop the count.

The Montgomery County Jail is a full-service jail at 345 W. Second Street. It opened in 1965 and was renovated in 1993, and it is the county's only adult jail. The Sheriff's Office runs it and houses both men and women. Most of the people inside are awaiting trial; others are serving misdemeanor sentences or waiting to be transferred to state prison after a felony sentence.

• Finding someone: The Sheriff's Office can confirm whether a person is in custody, what the charges are and whether bond has been set, at (937) 225-4357.
• Posting bond: The bond is paid for a specific court's case, so first find out which municipal court or Common Pleas case the hold belongs to.
• Holds: A person with a warrant from another county or a probation or parole hold may stay in jail even after posting bond on the new Dayton charge.

Visits, phone accounts and commissary deposits each have their own rules, which change from time to time; ask the jail before you go.

The Montgomery County Public Defender's office is in the Reibold Building, 117 S. Main Street, 4th Floor, and can be reached at (937) 225-4652. Staff attorneys represent adults charged with felonies in Common Pleas Court and with jailable misdemeanors in the municipal courts, as well as children in Juvenile Court delinquency cases. When the office has a conflict, for example because it already represents a co-defendant, the court appoints a private lawyer from its list.

To qualify, a defendant fills out a financial affidavit listing income, assets and household size. Ohio law allows a small application fee, generally no more than $25, which a court can waive. Ask for a lawyer at the first hearing. A person who is denied appointed counsel can still ask the judge to reconsider if their finances change.

The Prosecuting Attorney's office decides which felony cases go to the grand jury and what charges they carry. Its Intake and Grand Jury Section, (937) 225-3491, reviews police reports for those decisions. The office also handles juvenile delinquency cases from its Juvenile Division at the Juvenile Justice Center, (937) 225-4253. Its Victim/Witness Division in the Common Pleas building, (937) 225-5623, keeps victims informed under Marsy's Law.

The office runs a Diversion Division, (937) 225-5772, for some lower-level felony defendants, mostly first-time offenders charged with nonviolent crimes. A defendant who finishes the program's conditions, such as restitution, treatment, community service or classes, can have the charge dismissed. Defendants with a drug or alcohol problem or a mental illness may ask the judge for intervention in lieu of conviction under Ohio law. Misdemeanor diversion is decided separately by each city's prosecutor.

The General Division of the Common Pleas Court runs several treatment-focused dockets. In each one, a judge supervises the participant closely through frequent court check-ins, testing and services:

• Men's Achievement Recovery Court (MARC) — for men whose criminal cases are tied to substance use.
• Recovery IS Empowering Court (RISE) — a recovery docket on the court's list of specialized dockets.
• Mental Health Court — for defendants with serious mental illness, linking them to treatment.
• Veterans Treatment Court — for veterans, often with mentors and VA services.
• Kushinda Court — another specialized docket in the Common Pleas program.

Entry usually requires a referral from defense counsel or the judge and a screening, and it often depends on the prosecutor's agreement. The court's Pretrial Services section supervises some defendants released before trial, and its Investigative Services staff prepare presentence reports. Several municipal courts run their own recovery or OVI programs, so ask the defense lawyer what the court hearing the case offers.

A misdemeanor in Montgomery County is handled entirely in the municipal court for the place where it happened: shoplifting at a Dayton Mall store goes to Miamisburg, and a bar fight downtown goes to Dayton Municipal Court. The city prosecutor or law director files and tries the case. For charges filed by the Sheriff's deputies or the Highway Patrol in the townships, prosecution is handled under arrangements with the county or a local law director.

How the case moves

At arraignment the defendant pleads guilty, no contest or not guilty. After a not-guilty plea, the court sets a pretrial conference, where the defense lawyer and prosecutor review evidence such as police video and talk about a resolution. A defendant who wants a jury must file a written jury demand within the time the rules allow; otherwise the judge decides the case. Eight jurors sit on a misdemeanor jury, and all of them must agree. The speedy-trial law sets 90 days for first- and second-degree misdemeanors and 45 days for third- and fourth-degree ones, with three-for-one credit for jail days.

What the charges carry

• M1 — up to 180 days in jail and a $1,000 fine. This covers petty theft (under $1,000), assault and aggravated trespass.
• M2 — up to 90 days and $750.
• M3 — up to 60 days and $500.
• M4 — up to 30 days and $250. Simple criminal trespass is usually charged at this level.
• Minor misdemeanor — a fine of up to $150 and no jail.

A first OVI

A first OVI is a first-degree misdemeanor. The minimum is three consecutive days in jail, or a 72-hour driver intervention program instead. A high test (.17 or above) doubles that minimum to six days. Fines run from $375 to $1,075. A failed or refused breath test brings an administrative license suspension right away, and a conviction adds a court suspension of one to three years. Judges can grant limited driving privileges, and unlimited privileges with an ignition interlock may be available. An alcohol assessment and any recommended treatment are standard conditions.

Outcomes include dismissal, diversion, a plea to a reduced charge, fines and court costs, community control (probation), and jail time, which is often partly suspended. Most Montgomery County misdemeanors are resolved within one to four months, and many convictions can be sealed after a waiting period.

Every felony begins as a complaint in one of the municipal courts, but almost all of the real work happens after the case reaches the Common Pleas Court. Here is how a typical case moves:

1. Municipal court appearance. The judge sets bond and appoints counsel. A preliminary hearing date is set within the Crim.R. 5(B) limits.
2. Bindover or direct indictment. If the municipal judge finds probable cause, the case is bound over to the grand jury. The prosecutor may also present the case directly to the grand jury, which ends the municipal case.
3. Indictment. A Montgomery County grand jury hears the evidence in private and votes on the charges. A defendant who wants a quick plea deal may waive indictment and be charged by a bill of information.
4. Common Pleas arraignment. The defendant enters a plea at 41 N. Perry Street, and bond may be reviewed.
5. Discovery and pretrials. The prosecution turns over its evidence under Crim.R. 16. The defense can file motions to suppress evidence or dismiss charges, and the two sides negotiate.
6. Plea or trial. Most felony cases end in a plea. A trial is held before a 12-member jury, and the verdict must be unanimous.
7. Sentencing. After a conviction, Investigative Services usually prepares a presentence report before the judge imposes sentence.

Penalty ranges

• F5 — 6 to 12 months. Theft of $1,000 to $7,500 falls here, as do many lower-level drug offenses. For many first-time nonviolent defendants, the law presumes community control rather than prison.
• F4 — 6 to 18 months, including theft of $7,500 to $150,000.
• F3 — 9 to 36 months, or 12 to 60 months for certain offenses. Burglary of an occupied structure when no one is likely to be present is usually charged at this level.
• F2 — 2 to 8 years, including felonious assault and burglary when a person is likely present.
• F1 — 3 to 11 years, including aggravated burglary and the largest drug trafficking amounts.

Drug trafficking ranges from F5 to F1, depending on the drug and the amount. For F1 and F2 crimes committed on or after March 22, 2019, the Reagan Tokes Law requires an indefinite sentence: a minimum term chosen by the judge plus a possible additional period of up to half that minimum. A firearm specification adds mandatory prison time on top of the sentence for the underlying crime. Judges can impose community control for many F4 and F5 offenses and some F3s. Expect a typical felony to take four to twelve months.

Homicides, rapes and armed robberies in Dayton and the suburbs are prosecuted by the most experienced trial attorneys in the Prosecuting Attorney's office. Bond in these cases is often very high. Under Ohio's pretrial-detention law, the prosecutor can also ask the court to hold the defendant without bond after a hearing on dangerousness.

Sentencing exposure

• Aggravated murder carries death, life without parole, or life with parole eligibility after 20, 25 or 30 years. Ohio still has the death penalty, but no executions have been carried out since 2018, and the governor has issued repeated reprieves.
• Murder carries 15 years to life.
• Rape is a first-degree felony sentenced under the Reagan Tokes indefinite-term rules. A life sentence is possible when the victim is under 13 and force or certain other circumstances are involved.
• Aggravated robbery is a first-degree felony, and a gun specification usually adds mandatory time.

Before trial, the defense may hire experts, investigate the case and challenge forensic evidence. These cases often go before a jury, although many still end in negotiated pleas. Marsy's Law gives victims the right to be notified of hearings, to attend them and to be heard at bond, plea and sentencing hearings. A case of this kind commonly takes one to two years or longer before it is resolved.

Montgomery County runs a stand-alone Juvenile Court at the Juvenile Justice Center, 380 W. Second Street, (937) 496-7908. It hears delinquency cases involving children under 18, wherever in the county the offense took place. The Prosecuting Attorney's Juvenile Division files the complaints.

Intake and diversion

Not every police referral becomes a formal case. Court intake staff screen complaints, and many first or minor offenses are handled unofficially or through diversion: the child completes conditions such as classes, counseling, restitution or community service, and no formal adjudication follows. More serious or repeat cases are filed officially and go to hearings before a magistrate or judge.

Detention

A youth who is not released to a parent is held at the Montgomery County Juvenile Detention Center inside the Juvenile Justice Center, never in the adult jail. A judge or magistrate holds a detention hearing promptly, generally within 72 hours of the child being taken into custody or by the next court day, and decides whether continued detention is needed. The Public Defender's office represents many children in these cases.

Possible outcomes

• Probation, community service, restitution, treatment or electronic monitoring.
• Commitment to the Ohio Department of Youth Services (DYS) for felony-level offenses. County-based alternatives, such as the Center for Adolescent Services, may be used instead.
• Bindover to adult court. Ohio law requires transfer to adult court for some 16- and 17-year-olds charged with the most serious offenses, and for some 14- and 15-year-olds in limited situations. For other felonies, a judge may transfer a child 14 or older after an amenability hearing that examines whether the child can be rehabilitated in the juvenile system.
• Serious Youthful Offender sentencing combines a juvenile disposition with a stayed adult sentence, which may be imposed if the youth fails in the juvenile system.

Juvenile records are generally kept from the public, and many can be sealed, or later expunged, when the case is over.

Montgomery County is in the Southern District of Ohio. Federal crimes charged here go to the district's Western Division courthouse in downtown Dayton, the Walter H. Rice Federal Building and U.S. Courthouse at 200 W. Second Street. It sits on the same street as the county jail and juvenile court.

Federal offices in Dayton

Why a Dayton case becomes federal

A case goes to federal court when it involves a federal crime and a federal agency, such as the FBI, DEA, ATF, Homeland Security Investigations or the Postal Inspection Service, brings it to the U.S. Attorney. Some cases start with Dayton Police or the Sheriff and are adopted by a federal task force. Common examples are drug distribution conspiracies, gun possession by people with felony records, armed robberies of banks or businesses, child exploitation, and fraud involving the mail, banks or government benefits. Federal prosecutors and the county prosecutor decide between themselves where a case will be charged.

Steps in the federal system

After a federal arrest, the defendant appears before a U.S. magistrate judge in the Dayton courthouse. The magistrate explains the charges and appoints the Federal Public Defender or a CJA panel attorney for a defendant who cannot afford one. If the government seeks detention, the hearing is usually held within three court days. Under the Bail Reform Act, the magistrate either orders release on conditions supervised by U.S. Pretrial Services or orders the defendant held until trial. Federal court uses no money bail schedule and no commercial bondsmen.

If the case starts with a complaint, a grand jury indictment must follow within 30 days. The Speedy Trial Act then calls for trial within 70 days, though continuances often extend that period. Most cases end in plea agreements. At trial, 12 jurors must reach a unanimous verdict.

Sentencing comes several months after a plea or verdict. U.S. Probation prepares a presentence report that calculates the federal Sentencing Guidelines range; the judge must consider that range but is not bound by it. Mandatory minimum sentences, common in drug and firearm cases, do bind the judge. There is no parole in the federal system: with good-conduct credit, a prisoner serves about 85 percent of the sentence in the Bureau of Prisons, followed by a term of supervised release. Federal appeals from Montgomery County cases go to the Sixth Circuit court of appeals.

Custody

Federal detainees from Dayton remain in the custody of the U.S. Marshals, who house them in jails that contract with the Marshals Service. The Federal Bureau of Prisons inmate locator lets Dayton families look up a Montgomery County defendant by name or register number. A Dayton-area defendant kept before trial at a jail under contract may show up on that jail's roster. Federal prosecution of anyone under 18 is extremely rare.

This Montgomery County guide summarizes how criminal cases generally move through the Dayton-area courts; it is not legal advice, and procedures, phone numbers and programs change. Anyone charged with a crime should speak with a defense attorney or call the Montgomery County Public Defender at (937) 225-4652, and should confirm court dates with the clerk of the court hearing the case.
