New York metal detecting laws break down by who owns the ground. On state park land you need a $10 regional permit and can only detect on designated beaches in the off-season. New York City runs its own annual permit and confines detecting to unvegetated beach areas. Every National Park Service site in the state is off-limits. Private land requires the owner’s written permission. And no matter where you detect, any find worth $20 or more has to be returned to the owner or turned in to police.
State Park Permits and Rules
The Office of Parks, Recreation and Historic Preservation issues metal detecting permits by region. You pick the parks you plan to visit on the application, and the permit only covers those locations. The fee is $10, and the season tracks the swimming calendar rather than the calendar year. For the 2025–2026 season, detecting runs from September 2, 2025 through May 22, 2026, the months when beaches are closed to swimmers.1New York State Office of Parks, Recreation and Historic Preservation. Saratoga – Capital District Metal Detector Permit
Detecting is allowed only on designated beach areas. Lawns, flowerbeds, landscaped areas, shrubs, and anywhere near buildings are off-limits. Every New York State Historic Site is completely closed to detecting, without exception.1New York State Office of Parks, Recreation and Historic Preservation. Saratoga – Capital District Metal Detector Permit
Your digging tool must have a blade no larger than one and a half inches wide and six inches long. A full-sized shovel or garden spade is out. Carry the permit on you at all times and produce it for Park Police or any park employee who asks. Any trash you dig up is yours to pack out.1New York State Office of Parks, Recreation and Historic Preservation. Saratoga – Capital District Metal Detector Permit
The permit itself is explicit about finds. Any personal property worth $20 or more must be returned to the owner or deposited with Park Police under New York Personal Property Law. The permit does not authorize excavation of archaeological objects, and anything that looks archaeological must be handed over to park employees immediately.1New York State Office of Parks, Recreation and Historic Preservation.

New York City Park Rules
New York City runs a separate permit program through the NYC Parks Department. City rules restrict detecting to unvegetated beach areas only, which effectively excludes most of the city’s famous green spaces, Central Park included. You apply online through the NYC Parks website and must upload a valid photo ID showing your current address. Permits expire on December 31 each year, so renewal is annual.2NYC Parks. Metal Detector Permits
Even where detecting is allowed, the city adds more restrictions. You cannot probe or dig within 25 feet of any tree or within the tree’s drip line, whichever distance is greater. Athletic fields, manicured lawns, newly seeded lawns, monuments, memorial tree plantings, running tracks, golf courses, flower beds, gardens, woodlands, and native vegetation areas are all prohibited. Closed beaches are off-limits, whether closed for endangered species protection, dangerous conditions, or the absence of lifeguards.2NYC Parks. Metal Detector Permits
At renewal, you must give the Parks Department’s Urban Parks Service Division a list of all significant objects found under your permit during the prior year. No list, no new permit.2NYC Parks. Metal Detector Permits
Federal Parkland Is Off-Limits
New York holds numerous National Park Service sites, from the Statue of Liberty and Ellis Island to Saratoga National Historical Park and the Appalachian Trail corridor. Federal regulations flatly prohibit possessing or using a metal detector anywhere within a National Park Service unit. The only exception is a device broken down and packed in a way that prevents use while you are in the park.3eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources
Penalties are not trivial. Under the Archaeological Resources Protection Act, unauthorized excavation or removal of archaeological resources from federal land carries up to two years in prison and a $20,000 fine. Damage to federal property can reach ten years and $250,000.4National Park Service. Archaeological Resources Protection Act of 1979
Archaeological Objects and Human Remains on State Land
New York Education Law Section 233 makes it a class A misdemeanor to excavate, remove, injure, or destroy any object of archaeological, historical, cultural, scientific, or paleontological interest on state-owned land without written permission from the Commissioner of Education. The Attorney General can pursue both civil and criminal prosecution, and the state can seize both the items you found and the equipment you used to find them.5New York State Senate. New York Education Law EDN 233 – State Museum; Collections Made by the Staff
Permits for excavating these objects exist under the same statute, but they are issued through state agency heads to people authorized by the Commissioner of Education for scientific research. Recreational hobbyists do not qualify. The system is designed to preserve objects for the State Museum and state science service, not to let hobbyists keep what they find.6The New York State Museum. State Land Permits
Human remains are a separate and more serious problem. Under the New York State Unmarked Burial Site Protection Act, if you discover human remains you must stop any activity that could disturb the site and call 911 immediately. Failing to report the discovery of a burial site is a misdemeanor. Intentionally defacing or desecrating human remains or funerary objects is a felony.7The New York State Museum. New York State Unmarked Burial Site Protection Act
Unmarked burial sites in New York are not confined to obviously marked cemeteries. If you hit bone or anything that might be a funerary object, cover the hole, stop, and call it in.
Shipwrecks and Submerged State Land
Under the federal Abandoned Shipwreck Act, the U.S. government asserts title to abandoned shipwrecks embedded in state submerged lands or eligible for the National Register of Historic Places, then transfers that title to the state. New York consequently owns many of the wrecks in its coastal waters, rivers, and lake beds.8National Park Service. Abandoned Shipwreck Act Guidelines
The Office of General Services manages New York’s underwater lands, which are held in trust for the public. Detecting or salvaging items from submerged state land without authorization triggers the same state archaeological protections that apply on dry land.9Office of General Services. Lands Now or Formerly Underwater
Private Property and Local Rules
Detecting on land you do not own requires the landowner’s explicit permission. Without it, you are trespassing. Knowingly entering or remaining on someone else’s property without permission is trespass, classified as a violation under New York Penal Law.10New York State Senate. New York Penal Law 140.05 – Trespass If the property is fenced or otherwise enclosed to keep people out, the charge rises to criminal trespass in the third degree, a class B misdemeanor.11New York State Senate. New York Penal Law 140.10 – Criminal Trespass in the Third Degree
The absence of a fence does not make land public. Every parcel belongs to someone. Get written permission before you detect and carry it with you. That protects you from a trespass charge and avoids disputes over who owns what you dig up.
Towns, villages, and counties can add their own restrictions on top of state law. Some require a separate local permit or prohibit detecting entirely on municipal property like town squares and school grounds. Call the local town clerk before you visit.
What You Have to Do With What You Find
New York Personal Property Law Section 252 requires anyone who finds property worth $20 or more to either return it to the owner or deposit it with police within ten days. In a city, that means the local police station or headquarters. Outside a city, it goes to a state police station or the county, town, or village police, including the sheriff’s office. Finds made in a state park can be deposited with the regional state park police.12New York State Senate. New York Personal Property Law PEP 252
Police hold found property on a sliding scale tied to value: three months for items under $100, six months for $100 to $499, one year for $500 to $4,999, and three years for anything $5,000 or more. Three months before the holding period expires, police notify the owner (if known), anyone who has claimed the property, and the finder. If nobody claims it by the end of that notice period and no legal action is pending, the property goes to the finder.13New York State Senate. New York Personal Property Law 253 – Duties of Police
Skipping the process is a crime. Under New York Penal Law, keeping lost property you know belongs to someone else without making a reasonable effort to return it qualifies as larceny. The statute specifically defines larceny to include exercising control over lost or mislaid property when you know it is lost and fail to take reasonable steps to return it.14New York State Senate. New York Penal Law 155.05 – Larceny
Taxes on Valuable Finds
The IRS treats found property as taxable income. Under federal tax regulations, treasure trove is gross income in the year you take undisputed possession of it, valued in U.S. currency. An old coin or gold ring pulled from the sand has a fair market value, and the IRS expects you to report it on your return for the year you found it.15eCFR. 26 CFR 1.61-14 – Miscellaneous Items of Gross Income
Corroded coins and costume jewelry usually will not move the needle. But if you pull up something genuinely valuable, you owe income tax on its fair market value. Get an appraisal early: the IRS cares about what the item was worth when you found it, not what you eventually sell it for.
