Metal Detecting Laws in Tennessee: Permits, Parks, and Penalties

Metal detecting laws in Tennessee allow the hobby on private land with the owner’s permission, prohibit it on almost all public land, and — through an unusual state rule — give ownership of what you find to the landowner rather than to you. Break the wrong rule and penalties range from a $50 trespass fine to five years in federal prison.

Where You Can and Cannot Detect

The short version looks like this. Private property with the owner’s consent is the only reliably legal place to detect in Tennessee. State-owned land is closed to casual detecting under the Tennessee Antiquities Act. Tennessee Valley Authority land is closed, with no permit path for hobbyists. National Park Service sites are closed, and you cannot even carry an assembled detector through one. State parks technically allow detecting only to search for a specific lost item, and only under a park manager’s supervision. State natural areas are effectively closed. City and county parks vary, and some require permits.

That leaves private land as the practical answer for most detectorists, which makes the rules around permission and ownership the ones you need to get right.

Private Property: Permission Is Not Optional

Detecting on someone else’s land without consent is criminal trespass under TCA 39-14-405, a Class C misdemeanor carrying up to 30 days in jail and a fine of up to $50.1Justia Law. Tennessee Code 39-14-405 – Criminal Trespass2Justia Law. Tennessee Code 40-35-111 – Authorized Terms of Imprisonment and Fines Excavating and removing artifacts from private land without the owner’s express permission is a separate and far more serious offense under the Antiquities Act, a Class A misdemeanor with penalties up to 11 months and 29 days in jail and a $2,500 fine.3Justia Law. Tennessee Code 11-6-109

Verbal permission is legally valid, but a written agreement protects you far better. At minimum, put in writing which areas you can search, who owns what you find, whether you have to refill your holes, and a liability release for any injuries on the property. Landowners often respond better when you show up with paperwork than when you ask on the spot.

The Tennessee Ownership Rule That Catches People Off Guard

In most states, the person who finds treasure trove gets to keep it. Tennessee doesn’t work that way. Under Morgan v. Wiser, 711 S.W.2d 220 (Tenn. Ct. App. 1985), found property belongs to the owner of the land where it was discovered, not to the finder. The court’s reasoning was that the opposite rule would reward trespassers.

The practical result: if you dig up a gold coin on a farmer’s field with the farmer’s permission, the coin legally belongs to the farmer. Permission to detect is not the same as permission to keep what you find. The only way to walk away with your discoveries is to negotiate ownership up front, in writing, and spell out how any finds get divided — by type, by value, or by percentage. Silence on that point defaults to the landowner every time.

On state land, all excavated artifacts belong to the state of Tennessee and go to the Division of Archaeology.4Justia Law. Tennessee Code 11-6-105 – Excavation of State Lands On federal land, artifacts belong to the federal government.

State Land: The Antiquities Act

Tennessee’s main archaeological protection law is Title 11, Chapter 6 of the Tennessee Code. Under TCA 11-6-105, no one may excavate any archaeological site on land owned or controlled by the state unless acting as an authorized agent of the Division of Archaeology.4Justia Law. Tennessee Code 11-6-105 – Excavation of State Lands Casual metal detecting is not an authorized excavation program, so digging on state ground without a permit violates the statute.

TCA 11-6-109 makes unauthorized excavation and removal of artifacts a Class A misdemeanor, whether the ground is public or private.3Justia Law. Tennessee Code 11-6-109 Penalties reach 11 months and 29 days in jail and a $2,500 fine.2Justia Law. Tennessee Code 40-35-111 – Authorized Terms of Imprisonment and Fines

State Parks

Tennessee State Parks allows detector use only when someone is searching for a specific lost item, and only with a park manager supervising. Any other use requires written permission from both the State Archaeologist and the Director of State Parks.5Tennessee State Parks. Frequently Asked Questions Getting both approvals for recreational detecting is extremely unlikely. Designated archaeological zones, Civil War battlefields, and protected wildlife habitats are off-limits regardless of any request.

State Natural Areas

Tennessee’s Natural Areas Preservation Act, in Title 11, Chapter 14, protects designated scenic, scientific, and recreational sites from destruction or substantial diminishment.6Justia Law. Tennessee Code 11-14-108 – Designation of Areas Digging to recover a target is exactly the kind of ground disturbance the statute was written to prevent. Treat designated natural areas as closed.

Federal Land in Tennessee

TVA Property

This is the restriction that catches the most Tennessee detectorists off guard. The Tennessee Valley Authority manages hundreds of thousands of acres across the state, and detecting on TVA public land is strictly prohibited. Any artifacts found on TVA land are federal property, and removing them is illegal.7Tennessee Valley Authority. Look but Don’t Touch Artifacts on TVA Public Lands No permit process opens TVA land to recreational detecting. If you are near a TVA reservoir, dam, or managed recreation area, assume detecting is off the table.

National Park Service Sites

Tennessee’s NPS sites include Great Smoky Mountains National Park, Shiloh National Military Park, and Stones River National Battlefield. Federal regulations prohibit possessing or using a metal detector anywhere in an NPS area.8eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources The only exceptions are detectors broken down and packed so they cannot be used, or equipment used for authorized scientific or administrative work. Carrying an assembled detector through a national park can itself draw enforcement action.

The Archaeological Resources Protection Act

ARPA covers all federally managed land in Tennessee, including national forests, wildlife refuges, and TVA property. It makes it illegal to excavate, remove, or damage any archaeological resource on public land without a federal permit. An “archaeological resource” is any material remains of past human life or activity at least 100 years old, so a Civil War bullet or button pulled from federal ground qualifies.9Office of the Law Revision Counsel. 16 USC Chapter 1B – Archaeological Resources Protection

First-time ARPA violations carry fines up to $10,000 and up to one year in prison. When the archaeological or commercial value exceeds $500, the maximum jumps to $20,000 and two years. Repeat convictions can bring up to $100,000 and five years.9Office of the Law Revision Counsel. 16 USC Chapter 1B – Archaeological Resources Protection Because a five-year sentence makes a repeat ARPA violation a federal felony, the general federal sentencing statute allows individual fines up to $250,000.10Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine

Native American Remains and Cultural Items

If you find Native American human remains or cultural items on federal or tribal land, NAGPRA requires you to report the discovery by phone to the responsible federal agency immediately, followed by written documentation within 24 hours.11eCFR. 43 CFR Part 10 – Native American Graves Protection and Repatriation Regulations Trafficking in Native American remains without legal authority is a separate federal crime, up to a year and a day in prison for a first offense and up to 10 years for later violations.12Office of the Law Revision Counsel. 18 USC 1170 – Illegal Trafficking in Native American Human Remains and Cultural Items

Rivers, Lakes, and Shipwrecks

Water adds more federal law. The Rivers and Harbors Act makes it illegal to excavate, fill, or alter the channel of any navigable waterway without Army Corps of Engineers authorization.13Office of the Law Revision Counsel. 33 USC 403 – Obstruction of Navigable Waters Generally

The Abandoned Shipwreck Act transfers ownership of abandoned wrecks on state submerged lands to the state government.14Office of the Law Revision Counsel. 43 USC Chapter 39 – Abandoned Shipwrecks Recovering artifacts from a covered wreck without state authorization is illegal. Sunken military vessels and aircraft are protected wherever they lie, and federal regulations prohibit disturbing, removing, or damaging any sunken military craft without a permit.15eCFR. 32 CFR Part 767 Subpart A – Regulations and Obligations Given Tennessee’s Civil War history, the chance of running into a military-related object underwater is real.

City and County Parks

Local governments layer their own rules on top of state and federal law. Some Tennessee cities require permits for detecting in public parks. Others ban it in specific locations. Nashville’s Metro Parks system operates under its own policy manual. Knoxville restricts detecting in parks with historical significance. Restrictions vary by city, from time-of-day limits to full bans in designated zones to blanket rules against any ground disturbance. Rangers and local police can cite you and confiscate equipment. A phone call to the local parks department before you go out is usually enough to find out where you stand.

Taxes on What You Keep

The IRS treats found property as taxable income. Under Treasury Regulation 1.61-14, treasure trove is gross income in the year you reduce it to undisputed possession, valued at fair market value in U.S. dollars.16GovInfo. 26 CFR 1.61-14 – Miscellaneous Items of Gross Income You owe income tax on a valuable find in the year you dig it up, even if you never sell it. There is no minimum exemption. Keeping records of what you find, where, and any appraisals protects you if the IRS asks later.

Penalties Stacked by Law

Enforcement comes from state park rangers, TDEC officials, TVA police, National Park Service rangers, and local law enforcement. Equipment confiscation is common, and repeat offenders can be banned from public lands. Federal violations tend to be prosecuted more aggressively than state ones, particularly when historically significant artifacts are involved.
