Maryland Castle Doctrine & Stand Your Ground Laws

Overview

Maryland does not have a Stand Your Ground law. Maryland is a duty-to-retreat state, meaning that individuals generally have an obligation to retreat from a confrontation before using deadly force, if retreat can be done safely.

Maryland has a limited Castle Doctrine that applies within one's home, though it is based primarily on case law rather than a specific codified statute.

Note: Maryland's self-defense and use of force principles, including the duty to retreat and Castle Doctrine, are derived from common law and case law rather than specific statutes. The information below reflects widely recognized legal principles established through Maryland appellate court decisions. Individuals should consult Maryland case law and a qualified attorney for authoritative guidance.

Duty to Retreat

Under Maryland law, a person who is threatened outside of their home generally has a duty to retreat before resorting to deadly force, provided retreat can be accomplished safely. This duty to retreat is established through Maryland case law and common law principles, including decisions such as Crawford v. State and subsequent appellate rulings. The duty applies in all public spaces and locations outside the home.

Key points about the duty to retreat:

• The duty applies only when retreat is safely possible — if a person cannot retreat safely, they may use force including deadly force in self-defense
• The duty applies in all locations outside the home, including public streets, businesses, vehicles, and other people's property
• The person claiming self-defense bears the burden of showing that retreat was not safely available, or that the situation fell within the Castle Doctrine exception

Castle Doctrine (Home Defense)

Maryland recognizes a limited Castle Doctrine through case law:

• A person has no duty to retreat when they are inside their own home (their "castle") before using force, including deadly force, in self-defense
• The use of deadly force in the home is permitted when the occupant reasonably believes they are in imminent danger of death or serious bodily harm
• This protection generally applies to the dwelling itself and does not extend broadly to other property such as a yard, detached garage, or vehicle
• The defender must still meet the general requirements of self-defense (reasonable belief, not the initial aggressor, proportional force) — the Castle Doctrine only removes the duty to retreat within the home
• The Castle Doctrine does not create a blanket right to use deadly force against any intruder; the occupant must still face a genuine threat of death or serious bodily harm

Self-Defense Standards

Maryland's self-defense law, derived from common law and case law, generally requires:

1. Reasonable belief of imminent danger of death or serious bodily harm
2. The defender must not be the aggressor in the confrontation
3. The force used must be proportional — deadly force may only be used in response to a threat of death or serious bodily harm
4. Outside the home, the defender must have exhausted reasonable means of retreat before using deadly force

Perfect vs. Imperfect Self-Defense

Maryland recognizes two forms of self-defense:

• Perfect self-defense is a complete defense to a homicide charge. It requires that the defender had both an honest and reasonable belief that deadly force was necessary to prevent imminent death or serious bodily harm, and that the defender was not the aggressor and (outside the home) could not safely retreat.
• Imperfect self-defense may reduce a charge from murder to voluntary manslaughter when the defender had an honest but unreasonable belief that deadly force was necessary. This doctrine applies when one or more elements of perfect self-defense are missing — for example, if the belief in imminent danger was genuine but not objectively reasonable.

Firearm Definitions

Under Md. Code, Public Safety § 5-101, a "firearm" means:

• A weapon that expels, is designed to expel, or may readily be converted to expel a projectile by the action of an explosive; or
• The frame or receiver of such a weapon

The definition includes starter guns.

Maryland law also distinguishes between:

• Regulated firearm — a handgun, or a firearm classified or defined by Maryland law as an assault weapon
• Non-regulated firearm — any rifle or shotgun that does not meet the definition of an assault weapon

Wearing, Carrying, and Transporting Handguns

Under Md. Code, Criminal Law § 4-203, a person may not:

• Wear, carry, or transport a handgun, whether concealed or open, on or about the person
• Wear, carry, or knowingly transport a handgun, whether concealed or open, in a vehicle traveling on a road or parking lot generally used by the public, highway, waterway, or airway of the State

Maryland courts presume that a person who transports a handgun in a vehicle on a public road does so knowingly.

Exceptions to § 4-203

The prohibition does not apply to:

• Law enforcement officials of the United States, the State, or a county or city of the State
• Members of the armed forces or National Guard on duty or traveling to/from duty
• Law enforcement officials of another state temporarily in Maryland on official business
• Correctional officers or wardens of a correctional facility in the State
• Sheriffs and full-time or part-time assistant/deputy sheriffs
• Individuals issued a valid Maryland Wear and Carry Permit
• Persons transporting a handgun for lawful purposes (e.g., repair shop, shooting range, hunting) — each handgun must be unloaded and carried in an enclosed case or enclosed holster

Wear and Carry Permit Requirements

Per Md. Code, Public Safety § 5-303 through § 5-308, a person must have a permit before carrying, wearing, or transporting a handgun. Eligibility requirements under § 5-306 include:

• Not prohibited from possessing a firearm
• At least 21 years of age
• No conviction for a crime involving possession, use, or distribution of a controlled dangerous substance
• Not presently an alcoholic, addict, or habitual user of a controlled dangerous substance (unless under legitimate medical direction)
• Completion of the required training course
• No demonstrated propensity for violence or instability
• A good and substantial reason to wear, carry, or transport a handgun, such as a reasonable precaution against apprehended danger

A permit holder must carry the permit on their person whenever carrying, wearing, or transporting a handgun (§ 5-308).

HQL exemption: The Secretary may issue a Handgun Qualification License, without an additional application or fee, to a person who meets the requirements for a Wear and Carry Permit and does not already hold an HQL (§ 5-306).

Handgun Qualification License (HQL)

Under Md. Code, Public Safety § 5-117.1, a dealer or any other person may not sell, rent, or transfer a handgun to a purchaser, lessee, or transferee unless that person presents a valid Handgun Qualification License (HQL). Requirements include:

• At least 21 years of age
• A resident of the State
• Satisfactory completion of a firearms safety training course approved by the Secretary within 3 years prior to application
• Not otherwise prohibited from purchasing or possessing a handgun under State or federal law

The HQL expires 10 years from the date of issuance.

Important: An HQL is not a carry permit — it only authorizes purchase, rental, or receipt of a handgun. A Maryland Wear and Carry Permit is a separate credential.

HQL Exemptions

The HQL requirement does not apply to:

• Persons possessing valid credentials or retirement credentials from a law enforcement agency of the United States, the State, or any local Maryland law enforcement agency
• Active or retired members of the U.S. armed forces or National Guard possessing a valid military identification card
• Persons purchasing, renting, or receiving an antique, curio, or relic firearm as defined in federal law or Bureau of Alcohol, Tobacco, Firearms and Explosives determinations

Persons Prohibited from Firearm Possession

Under Md. Code, Public Safety § 5-133, § 5-118, and related sections, a person may not possess a regulated firearm if they:

• Have been convicted of a disqualifying crime or a crime of violence
• Have been convicted of a violation classified as a common law crime and received imprisonment of more than 2 years
• Have been convicted of a violation of Criminal Law Article §§ 5-602, 5-603, 5-604, 5-605, 5-612, 5-613, or 5-614 (controlled dangerous substance offenses)
• Are a fugitive from justice
• Are a habitual drunkard or addicted to/habitual user of a controlled dangerous substance
• Suffer from a mental disorder (as defined in Health–General Article § 10-101(f)(2)) with a history of violent behavior
• Have been found incompetent to stand trial under Criminal Procedure Article § 3-106
• Have been found not criminally responsible under Criminal Procedure Article § 3-110
• Have been voluntarily admitted for more than 30 consecutive days to a mental health facility
• Have been involuntarily committed to a mental health facility
• Are under the protection of a court-appointed guardian (except solely for physical disability)
• Are a respondent against whom a current non ex parte civil protective order has been entered under Family Law Article § 4-506, or against whom a protective order from another state or Native American tribe is in effect
• If under 30 years old, have been adjudicated delinquent for an act that would be a disqualifying crime if committed as an adult

Under § 5-133.1, a person prohibited from possessing a regulated firearm is also prohibited from possessing ammunition.

Firearm Storage Requirements

Under Md. Code, Criminal Law § 4-104, a person may not store or leave a loaded firearm in a location where the person knew or should have known that an unsupervised child (under 16 years of age) would gain access to the firearm. The term "firearm" under this section includes but is not limited to a handgun, rifle, shotgun, short-barreled rifle, or short-barreled shotgun.

Exceptions apply if:

• The child's access is supervised by an individual at least 18 years old
• The child obtained access through unlawful entry
• The firearm is in the possession or control of a law enforcement officer engaged in official duties
• The child has a certificate of firearm and hunter safety issued under Natural Resources Article § 10-301.1

New Resident Firearm Registration

As of October 1, 2013, new residents of Maryland are required to register all regulated firearms with the Maryland State Police. Registration is handled through the MSP Licensing Division. Voluntary registration is also available for existing residents.

Extreme Risk Protective Orders (ERPO)

Effective October 1, 2018 (HB1302, Ch. 250 of the 2018 Legislative Session), Maryland's Extreme Risk Protective Order law allows a court to temporarily require a person to:

• Surrender all firearms and ammunition to law enforcement
• Not purchase or possess firearms or ammunition

With reasonable belief that a person meets the requirements, an ERPO also allows the court to refer someone for an emergency evaluation due to mental disorder.

What an ERPO Cannot Do

An ERPO cannot order a person to:

• Stop threatening or committing abuse
• Stay away from a home, place of employment, or school
• Have no contact with the petitioner or others

Other legal remedies (such as peace orders or protective orders) exist for those protections. An ERPO is a civil order, not a criminal charge.

Who Can File an ERPO

A petition may be filed by a:

• Spouse, cohabitant, or relative by blood, marriage, or adoption
• Person with children in common
• Current dating or intimate partner
• Current or former legal guardian
• Law enforcement officer
• Medical professional who has examined the respondent — including a physician, psychologist, clinical social worker, licensed clinical professional counselor, clinical nurse specialist in psychiatric and mental health nursing, psychiatric nurse practitioner, licensed clinical marriage or family therapist, or health officer or designee of a health officer

A petitioner who, in good faith, files a Petition for Extreme Risk Protective Order is not civilly or criminally liable for filing the petition.

An ERPO can be filed against a minor.

Risk Factors Considered

Factors demonstrating possible risk include:

• Alarming behavior and statements
• Unlawful firearm possession
• Reckless or negligent firearm use
• Violence or threats of violence to self or others
• Violating peace or protective orders
• Drug and/or alcohol abuse
• Information contained in health records

Duration of ERPO Orders

The final hearing is usually scheduled within 7 days after the respondent is served with the Temporary ERPO. The court may hold the final hearing with or without the respondent being present, provided the respondent has been served.

Firearm Surrender Requirements

• If served in person, the respondent must immediately surrender all firearms to the officer
• If served by mail, the respondent must contact the designated law enforcement agency and arrange immediate surrender
• When transporting a firearm for surrender: notify the agency, ensure the firearm is unloaded, transport directly to the station, and carry a copy of the ERPO
• Violating an ERPO is a crime that may result in contempt, arrest, criminal prosecution, imprisonment, and/or fine. The respondent can be arrested with or without a warrant if a law enforcement officer has probable cause.

Return of Firearms

When the ERPO terminates or expires, the custodial law enforcement agency notifies the respondent and verifies they are not otherwise prohibited from possessing firearms. Firearms are returned no later than:

• 14 days after expiration of an Interim or Temporary ERPO
• 14 days after a court terminates a Final ERPO
• 48 hours after expiration of a Final ERPO

Appeals, Modifications, and Extensions

• Either party may appeal a District Court judge's decision to grant or deny an ERPO. The appeal is filed in the District Court where the petition was decided. The District Court judgment remains in effect until superseded by a Circuit Court judgment.
• A judge may modify, rescind, or extend an ERPO after a hearing on a Petition to Modify/Rescind/Extend.
• There are no filing fees, service fees, or appeal fees for Extreme Risk Protective Orders.

Emergency Evaluation Referral

Under the ERPO law, the court can also refer the respondent for an emergency evaluation for a mental disorder:

• If a commissioner finds probable cause based on the ERPO petition and addendum, they are required to refer the respondent to law enforcement for a determination
• If a judge finds probable cause, they are required to refer the respondent for an emergency evaluation under a temporary ERPO and authorized to do so under a final ERPO

Confidentiality of ERPO Records

All court records relating to an ERPO are confidential and will not appear on the Judiciary's Case Search. Contents may not be divulged, by subpoena or otherwise, except by court order for good cause. However, the following parties have access:

• Personnel of the court
• The respondent or counsel for the respondent
• Authorized personnel of the Maryland Department of Health
• Authorized personnel of a local core service agency or local behavioral health authority
• Law enforcement agencies
• A person authorized by court order for good cause shown

Federal Funding for ERPO Programs

Maryland receives federal funding through the Byrne State Crisis Intervention Program (Byrne SCIP), authorized by the Bipartisan Safer Communities Act (BSCA) of 2022 (Pub. L. No. 117-159). This funding supports ERPO program implementation, training, public awareness, behavioral health deflection, and law enforcement firearm storage and tracking infrastructure. The program is administered in Maryland by the Governor's Office of Crime Prevention, Youth, and Victim Services (GOCPYVS).

Additional Firearm Regulations

• 7-day waiting period (§ 5-123): A licensee may not sell, rent, or transfer a regulated firearm until 7 days after the firearm application is executed and forwarded to the Secretary.
• 30-day purchase limit (§ 5-128): A person may not purchase more than one regulated firearm in a 30-day period. Exceptions include purchases of antique firearms, designated collectors, law enforcement officers, licensees, and exchanges or replacements of a regulated firearm within 30 days of the original purchase.
• Straw purchases prohibited (§ 5-136): A person may not knowingly or willfully participate in a straw purchase of a regulated firearm. A "straw purchase" means a sale in which a person uses another (the straw purchaser) to complete the application, take initial possession, and subsequently transfer the firearm to the actual buyer.

Law Enforcement Officers Safety Act (LEOSA)

Qualified separated (retired) law enforcement officers from the Maryland Department of State Police may obtain a LEOSA identification card to carry a concealed handgun under federal law (18 U.S.C. §§ 926B and 926C). Requirements include:

• Separation in good standing from a law enforcement agency
• At least 10 years of aggregate service as a law enforcement officer (or separation due to service-connected disability)
• Annual firearms qualification meeting active-duty standards, through a Maryland Police and Correctional Training Commission certified instructor
• Not found unqualified for mental health reasons
• Not prohibited by State or federal law from receiving a firearm

The LEOSA ID card costs $8.00 (non-refundable) and is valid for one year from the date of firearms qualification. Members of other Maryland law enforcement agencies should contact their respective agencies for LEOSA credentials.
