Yes, you can carry mace in NYC, but New York sets some of the strictest rules in the country. You must be at least 18, have no felony or assault conviction, and buy a canister of no more than 0.75 ounces in person from a licensed New York firearms dealer or pharmacist. Ordering pepper spray online and shipping it to a New York address is illegal, even though the products are widely sold elsewhere.
Who Qualifies to Carry
New York Penal Law 265.20 creates the exemption that lets ordinary residents possess a self-defense spray. To use it, every one of these has to be true about you:1New York State Senate. New York Penal Law PEN 265.20 – Exemptions
- You are at least 18 years old.
- You have no felony conviction in New York, and no out-of-state conviction for a crime that would be a felony here.
- You have no prior conviction for an assault crime, misdemeanor or felony.
A separate provision also bars anyone who has been judicially determined incompetent and certified as unsuitable to possess a self-defense spray by a hospital director or physician in charge of a mental health institution.2NY Penal Law. Article 265 – NY Penal Law
If any of those apply to you, carrying a canister is criminal possession of a weapon in the fourth degree, regardless of where or how you got it.
Where and How to Buy It
You can only buy a self-defense spray from a licensed firearms dealer, a licensed pharmacist, or another vendor specifically authorized by the Superintendent of State Police. No other retailer is allowed to sell these devices in New York.1New York State Senate. New York Penal Law PEN 265.20 – Exemptions
At the counter, the seller has to verify your age and have you sign a sworn statement confirming you have no disqualifying felony or assault conviction. That form, approved by the Superintendent of State Police, stays on the seller’s premises and can be inspected by law enforcement at any reasonable time.3New York Codes, Rules and Regulations. 9 CRR-NY 474.5 – Form Certification for the Purchase of a Self-Defense Spray Device You are 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 show up constantly on sites like Amazon. A bill introduced by State Senator Jessica Scarcella-Spanton would lift the online ban and expand which businesses can sell self-defense sprays, but as of early 2026 it remains in the Senate Codes Committee and is not law.4New York State Senate. NY State Senate Bill 2025-S4922A If a canister arrived at your door from an online retailer, you are not legally in the clear just because the seller shipped it.
What Counts as a Legal Canister
New York limits self-defense spray canisters to a net weight of 0.75 ounces. The device has to be pocket-sized and designed to temporarily disable someone through a chemical or organic compound such as oleoresin capsicum (the active ingredient in pepper spray) or a tear gas agent like CN or CS.5Cornell Law Institute. New York Code Rules and Regulations 10 NYCRR 54.3
Every 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 anyone with a felony or assault conviction is illegal. If the canister already bears the labels required by the U.S. Consumer Product Safety Commission and California’s labeling rules, the New York warning can appear on the packaging instead of the device itself.5Cornell Law Institute. New York Code Rules and Regulations 10 NYCRR 54.3
Bear spray does not qualify. It comes in canisters far larger than 0.75 ounces and is designed for wildlife, not people. Carrying it in NYC as a self-defense tool violates both the size cap and the intended-use requirements.
When You Can Legally Use It
Owning a legal canister does not give you a free pass to deploy it. New York Penal Law Article 35 lets you 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 feeling of unease, an argument that ended minutes ago, or a verbal threat with no physical component does not clear that bar.
The response also has to be proportional. Spraying someone because they cut in line or bumped your shoulder is not self-defense. Spraying someone who is lunging at you or physically cornering you is the kind of scenario the law protects. You are not required to retreat before using non-deadly force like mace, so if someone is coming at you on the street, you do not have to turn and run before deploying it.
Using mace to commit a crime, settle a personal dispute, or resist a lawful arrest is always illegal and will lead to charges well beyond simple possession.
Places You Cannot Bring It
Even with a lawful canister on your hip, several locations are off-limits.
Federal Buildings and Courthouses
Federal law prohibits bringing any dangerous weapon into a federal facility, and the Department of Homeland Security has confirmed that mace and pepper spray fall within that definition. Earlier interpretations that allowed small OC sprays under 2% concentration have been explicitly overruled.6U.S. Department of Homeland Security. FAQ Regarding Items Prohibited from Federal Property Carrying 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. Bringing it into a federal courthouse raises the maximum to two years.7Office of the Law Revision Counsel. 18 U.S. Code 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities
Some federal buildings offer lockboxes outside the security screening area where you can store personal items before entering, but the facility is not responsible for your belongings.6U.S. Department of Homeland Security. FAQ Regarding Items Prohibited from Federal Property
State and City Buildings
The New York State Capitol and Legislative Office Building in Albany prohibit all noxious materials, including sprays that are otherwise legal under Penal Law 265.20.8Empire State Plaza. Security Procedures and Prohibited Items – Empire State Plaza Any government building with security screening will typically enforce similar rules, so if you are walking through a metal detector, expect the canister to be confiscated.
Airports and Flights
Mace and pepper spray are banned from carry-on bags at every airport. The TSA allows one container of up to four fluid ounces in checked luggage, as long as the canister has a safety mechanism to prevent accidental discharge.9Transportation Security Administration. Pepper Spray Sprays containing more than 2% tear gas (CS or CN) by mass are banned from checked bags entirely. Getting caught with pepper spray at a checkpoint can result in a civil penalty starting at $450 for a first offense.10Transportation Security Administration. Civil Enforcement Rules at your destination may differ, so check before you fly.
Penalties for Breaking the Rules
What you face depends on what you did wrong and whether anyone got hurt.
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.11New York State Senate. New York Penal Law PEN 265.01 – Criminal Possession of a Weapon in the Fourth Degree That covers being under 18, having a disqualifying conviction, or buying through unauthorized channels. A conviction carries up to one year in jail, a fine of up to $1,000, or both.12New York State Senate. New York Penal Law PEN 80.05 – Fines for Misdemeanors and Violations
Assault Charges
Spraying someone outside a genuine self-defense scenario adds assault to any possession issue. Intentionally causing physical injury with mace is assault in the third degree, another Class A misdemeanor with a one-year jail ceiling.13New York State Senate. New York Penal Law 120.00 – Assault in the Third Degree Causing serious physical injury, or spraying someone during another crime, pushes the charges into felony territory.
Spraying a Police or Peace Officer
Intentionally spraying a police or peace officer to prevent them from performing a lawful duty is a standalone crime under Penal Law 195.08. It is a Class D felony, carrying a potential prison sentence of up to seven years.14New York State Senate. New York Penal Law PEN 195.08 – Obstructing Governmental Administration by Means of a Self-Defense Spray Device
Civil Liability
Criminal charges are not the only risk. A person you spray can sue you for battery, and if a court finds the use unjustified, you could owe damages for medical bills, lost income, and pain and suffering. Even a spray you genuinely believed was defensive can produce a lawsuit if the other person’s version of events differs from yours.
A weapons misdemeanor on your record can also ripple through employment, professional licensing, and housing applications. In fields like healthcare, education, or finance, a weapons conviction can disqualify you from licensure entirely.
