Maryland Firearms Laws and Regulations

Not all codes and regulations are quoted, and you should spend the time to familiarize yourself with the entirety of Maryland’s laws relating to firearms possession and use.

Requirements pursuant to COMAR12.04.01.12


You are not liable for using force, to include deadly force if reasonable, to defend your home or business


...You are not civilly liable for any act or omission in providing assistance or medical aid to a victim at the scene of an emergency, if:

        (1)    The assistance or aid is provided in a reasonably prudent manner;

        (2)    The assistance or aid is provided without fee or other compensation; and

        (3)    The individual relinquishes care of the victim when someone who is licensed or certified by this State to provide medical care or services becomes available to take responsibility.


In Baltimore Transit Co. v. Faulkner, a civil lawsuit for assault and battery, the Court of Appeals set forth the general common law principles of the doctrine of self-defense:

The law of self-defense justifies an act done in the reasonable belief of immediate danger. If an injury was done by a defendant in justifiable self-defense, he can neither be punished criminally nor held responsible for damages in a civil action. ... One who seeks to justify an assault on the ground that he acted in self-defense must show that he used no more force than the exigency reasonably demanded. The belief of a defendant in an action for assault that the plaintiff intended to do him bodily harm cannot support a plea of self-defense unless it was such a belief as a person of average prudence would entertain under similar circumstances. The jury should accordingly be instructed that to justify assault and battery in self-defense the circumstances must be such as would have induced a reasonable man of average prudence to make such an assault in order to protect himself. The question whether the belief of the defendant that he was about to be injured was a reasonable one under all the circumstances is a question for the consideration of the jury.


The Court of Appeals said in the case that, even if the plaintiff had struck the defendant's employees first, the plaintiff would still be entitled to prevail in an action for battery if the defendant's employees, in repelling the plaintiff's acts, "used unreasonable and excessive force, meaning such force as prudent men would not have used under all the circumstances of the case."


Maryland follows common law principles on the use of deadly force in self-defense. In the case of State v. Faulkner,  the Court of Appeals summarized those principles, and stated that a homicide is justified on the ground of self-defense if the following criteria are satisfied:

(1) The accused must have had reasonable grounds to believe himself in apparent imminent or immediate danger of death or serious bodily harm from his assailant or potential assailant;

(2) The accused must have in fact believed himself in this danger;

(3) The accused claiming the right of self defense must not have been the aggressor or provoked the conflict;

(4) The force used must have not been unreasonable and excessive, that is, the force must not have been more force than the exigency demanded.

Crawford v. State.

“One Faced With Attack Upon His Dwelling Need Not Retreat, But May Stand Ground, And If Necessary To Repel Attack, Kill Attacker — General Applicability Of Rules Involving Right To Defend One's Person — Force Used Must Not Be Excessive. It is a generally accepted rule, with which this Court indicated its agreement, that a man faced with a danger of an attack upon his dwelling need not retreat from his home in order to escape the danger, but instead he may stand his ground, and if necessary to repel the attack, he may kill the attacker.” 

Barton v. State

A person does not have to be the owner of the home or the head of the household in order to be able to invoke the "Castle Doctrine." Instead, "any member of the household, whether or not he or she has a proprietary or leasehold interest in the property, is within its ambit. ... "

See also Roach v. State.


Maryland follows the common law rule that, outside of one's home, before using deadly force in self-defense, a person has the duty "'to retreat or avoid danger if such means were within his power and consistent with his safety.'" But a person does not have to retreat if it would not be safe for the person to do so. "[I]f the peril of the defendant was imminent, he did not have to retreat but had a right to stand his ground and to defend and protect himself."
