You can carry mace in NYC, but only if you clear a specific set of hurdles. You must be at least 18, have no felony or assault conviction, and buy the canister in person from a licensed firearms dealer or pharmacist in New York. The container cannot exceed 0.75 ounces, and having one shipped to a New York address from an online retailer is illegal. Within those limits, carrying pepper spray or mace for self-defense is lawful.
Who Qualifies to Carry
New York Penal Law 265.20 lays out the exemption that lets ordinary people possess a self-defense spray. You have to satisfy every condition, not just one:1New York State Senate. New York Penal Law PEN 265.20 – Exemptions
- You are 18 or older.
- You have no felony conviction in New York, and no conviction elsewhere for a crime that would be a felony here.
- You have no assault conviction of any kind, misdemeanor or felony.
Miss any one of these and possession itself becomes a crime, regardless of why you wanted the spray.
Where and How You Have to Buy It
The retail side is just as tightly controlled as the possession side. Legal sellers are limited to licensed firearms dealers, licensed pharmacists, and other vendors specifically authorized by the Superintendent of State Police. No other store is permitted to sell you a canister.1New York State Senate. New York Penal Law PEN 265.20 – Exemptions
Before the sale goes through, the seller has to check your age and have you sign a sworn statement confirming you have no disqualifying conviction. The signed form stays on the seller’s premises and is subject to inspection by law enforcement at any reasonable time.2New York Codes, Rules and Regulations. 9 CRR-NY 474.5 – Form Certification for the Purchase of a Self-Defense Spray Device You are also capped at two canisters per transaction.1New York State Senate. New York Penal Law PEN 265.20 – Exemptions
Ordering online and shipping to a New York address is illegal, even though pepper spray keychains are freely sold on sites like Amazon. State Senator Jessica Scarcella-Spanton has introduced a bill that would lift the online-purchase ban and expand the list of eligible sellers, but as of early 2026, it is still in the Senate Codes Committee.3New York State Senate. NY State Senate Bill 2025-S4922A Until it passes, the in-person rule stands.
Canister Size and Product Rules
A legal self-defense spray in New York weighs no more than 0.75 ounces net. It has to be pocket-sized and designed to temporarily disable a person using a chemical or organic compound such as oleoresin capsicum (OC, the active ingredient in pepper spray) or a tear gas agent like CN or CS.4Cornell Law Institute. New York Code Rules and Regulations 10 NYCRR 54.3
Each canister must carry a warning label stating that using it for anything other than self-defense is a crime, that the contents are dangerous, and that possession by anyone under 18 or with a disqualifying conviction is illegal. If the canister already bears the labels required by the U.S. Consumer Product Safety Commission and California, the New York warning can appear on the packaging instead of the device.4Cornell Law Institute. New York Code Rules and Regulations 10 NYCRR 54.3
People use “mace” and “pepper spray” as if they meant the same thing. Chemically they differ: traditional Mace was built around CN tear gas, while modern pepper spray uses OC. Many current Mace-branded products now contain OC or a blend of OC and CN. Under New York law, both OC sprays and tear-gas-based sprays qualify as self-defense spray devices if they meet the size and labeling rules.
Bear spray does not qualify. It is an EPA-regulated pesticide meant for wildlife, comes in canisters well over 0.75 ounces, and is illegal to use on people. Carrying it as a self-defense tool in NYC violates both the size cap and the intended-use requirement.
When You Can Legally Use It
Owning a legal canister does not give you a free hand. New York Penal Law Article 35 sets the standard for self-defense: you may use physical force when you reasonably believe it is necessary to defend yourself or someone else from the imminent use of unlawful physical force. Imminent is the operative word. A vague sense of unease, an argument that ended minutes earlier, or a verbal threat with no physical component does not meet it.
The force also has to match the threat. Spraying someone for cutting in line or bumping your shoulder is not self-defense. Spraying someone who is lunging at you or physically cornering you is the situation the exemption was written for.
New York’s duty to retreat applies to deadly force, not to non-deadly force like mace. If someone is coming at you on the street, you are not required to try to flee before spraying, so long as you genuinely believe an attack is about to happen.
Using mace to commit a crime, settle a personal dispute, or resist a lawful arrest is never covered, and the charges that follow will be far worse than a possession issue.
Where You Cannot Bring It
A legal canister does not travel everywhere with you.
Federal Buildings and Courthouses
Federal law bans dangerous weapons from federal facilities, and the Department of Homeland Security has confirmed that mace and pepper spray fall within that definition. Older interpretations that let small OC sprays under 2% concentration through have been explicitly overruled.5U.S. Department of Homeland Security. FAQ Regarding Items Prohibited from Federal Property
Bringing mace into a general federal building, such as a Social Security office, IRS field office, or post office, is punishable by up to one year in prison. In a federal courthouse, the maximum climbs to two years.6Office of the Law Revision Counsel. 18 U.S. Code 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities Some federal buildings have lockboxes near the entrance for personal items like mace, located outside the security screening area, though the facility takes no responsibility for what you store there.5U.S. Department of Homeland Security. FAQ Regarding Items Prohibited from Federal Property
State and City Buildings
The State Capitol and Legislative Office Building in Albany prohibit all noxious materials, including sprays otherwise legal under Penal Law 265.20.7Empire State Plaza. Security Procedures and Prohibited Items – Empire State Plaza Any state or city building with metal detectors at the door should be assumed to enforce the same rule. Expect confiscation.
Flying With Pepper Spray
You cannot bring mace or pepper spray in a carry-on bag out of any New York-area airport, ever. The TSA permits one container of up to four fluid ounces in checked luggage, and the canister must have a safety mechanism that prevents accidental discharge.8Transportation Security Administration. Pepper Spray Sprays with more than 2% CS or CN by mass are banned from checked bags entirely. Airlines can add their own restrictions on top, so check before you pack.
Getting caught with pepper spray at a checkpoint carries a civil penalty ranging from $450 to $2,570 for a first offense, with higher fines for repeat violations.9Transportation Security Administration. Civil Enforcement And even if you legally check a canister out of New York, the state you land in may have different rules on size, concentration, or possession. Look those up first.
Penalties If You Get It Wrong
Unlawful Possession
Possessing a self-defense spray without meeting the legal requirements is criminal possession of a weapon in the fourth degree, a Class A misdemeanor.10New York State Senate. New York Penal Law PEN 265.01 – Criminal Possession of a Weapon in the Fourth Degree That includes being under 18, having a disqualifying conviction, or buying through an unauthorized channel. A conviction carries up to one year in jail, a fine of up to $1,000, or both.11New York State Senate. New York Penal Law PEN 80.05 – Fines for Misdemeanors and Violations
Assault
Spray someone outside a real self-defense scenario, and you face assault charges on top of the possession issue. Intentionally causing physical injury with mace is assault in the third degree, also a Class A misdemeanor with a one-year jail ceiling.12New York State Senate. New York Penal Law 120.00 – Assault in the Third Degree If you cause serious physical injury, or spray someone while committing another crime, the charges move into felony range.
Spraying a Police Officer
Intentionally spraying a police officer or peace officer to prevent them from performing a lawful duty is its own crime under Penal Law 195.08. It is a Class D felony carrying up to seven years in prison.13New York State Senate. New York Penal Law PEN 195.08 – Obstructing Governmental Administration by Means of a Self-Defense Spray Device
Civil Suits
Criminal charges are only part of the exposure. The person you sprayed can sue you for battery, and if a court finds the use was unjustified, you can be ordered to pay for medical bills, lost income, and pain and suffering. Even a spray you genuinely believed was defensive can lead to a civil suit when the other side tells a different story.
Collateral Consequences
A weapons-related misdemeanor follows you through background checks for employment, professional licensing, and housing. In fields like healthcare, education, and finance, a weapons conviction can bar licensure. Because the statute is a weapons charge and not a simple violation, landlords and employers tend to weigh it heavily.
