Metal Detecting in Michigan

1. The rule, in full

Michigan – Land Use Order of the Director 5.26

Read from the signed Land Use Orders of the Director published by the Michigan Department of Natural Resources (michigan.gov, LUOD.pdf, 732 KB), the whole document, 254,167 characters of extracted text, read chapter by chapter. Checked 3 Oct 2026.

Rewritten 3 Oct 2026 during the forestry and wildlife sweep. The previous version of this entry stated the rule as a prohibition "on all Bureau-administered lands except designated swimming beaches, designated day use areas, campgrounds and parking lots", with no section pin and no quotation, written from the department's metal detecting web page. That is not what Order 5.26 says, and the mechanism it described is not the one the Order operates. Recorded in METHODOLOGY under rule 11.

Operative text, Order 5.26, "Metal detector use in state parks and recreation areas, prohibited conduct":

"A person shall not do any of the following in any state park (SP) or recreation area (RA):
(1) Use a metal detector outside of a designated area illustrated as open on the access map as published on the department website by April 15th of each calendar year, without written authorization of the unit supervisor or manager." History: Iss. Dec. 14, 2023; Am. 6, 2023, Post Dec. 15, 2023.

The rule turns on a map, republished every year. This is the part that matters most in practice and the part the old entry got wrong. There is no standing list of permitted place types. What is open is whatever the access map published on the department website by 15 April of that calendar year shows as open, and it can differ from one year to the next. A reader who learned a list of place types from this page and went detecting on that basis would be working from something the Order replaced.

There are two lawful routes, and the second is easy to miss. Detecting inside an area the current map illustrates as open needs nothing further. Outside it, the Order does not prohibit detecting outright: it prohibits detecting "without written authorization of the unit supervisor or manager". So the permission route exists everywhere in a state park or recreation area, and the map decides only where you may go without asking.

Scope: state parks and recreation areas, as the Order itself says. Order 5.26 opens "in any state park (SP) or recreation area (RA)", the same formula Chapter V uses throughout. Neither "state park" nor "recreation area" is defined in the Order or in its Chapter I, Definitions and General Provisions; those terms come from the Natural Resources and Environmental Protection Act and have not been read for this entry.

The previous determination, "DNR-administered land only", was an inference and it was wrong. It reasoned from the authorising section, MCL 324.504, which gives the Director authority over department land. Authority over all department land is not an order that reaches all department land. Order 5.26 reaches two classes of it. This is METHODOLOGY rule 2: the scope language settles reach, not the grant of power.

What the rest of the Orders say about detecting: nothing. The Land Use Orders are organised in chapters by land class, and the whole document was read for this entry. "Metal detector" appears exactly twice in it, both in Order 5.26, once in its heading and once in its text.

So on Michigan state forest land and on state game and wildlife areas there is no detector rule in the Land Use Orders at all. That is a checked result rather than an untested gap: Chapters III and IV run to 40,592 and 85,573 characters and neither mentions a metal detector, excavation, an artifact or archaeology. Instruments outside the Land Use Orders have not been read for those classes.

Determination: Order 5.26 covers Michigan state parks and recreation areas. It does NOT reach municipal parks, and within state land it does NOT reach state forests, game and wildlife areas, public access sites and harbours or fisheries facilities.

Not restated here, and why. The previous entry carried a note that recovered items must be checked by a unit employee, that artifacts are left in position, and that relics or abandoned property of historical value are retained by the state. None of that is in Order 5.26 or anywhere else in the Land Use Orders. It came from the department's web page, which makes it agency policy rather than the Order, and it has not been re-read since 19 Sep

• Under rule 11 the department is authoritative about its own policy, so the substance may well be right, but it is not going back on this page as though the Order said it. It is queued for re-reading at source. Sources: michigan.gov signed Land Use Orders of the Director (LUOD.pdf) and Chapter III as separately published, both parsed locally, fetched 3 Oct 2026. Checked 3 Oct 2026.

2. Cities in Michigan that publish a rule

3 cities in Michigan publish a rule we can quote, out of 92 checked.

Of the 92 checked, 65 had pages on the city’s own site that we found and read. For the other 27 we could not locate a municipal source, so nothing is claimed about them either way.

3. County rules

County rules exist in Michigan, and they govern county land only. 1 county rule surfaced while checking cities in this state. Each was read and then set aside, because a county park rule does not answer whether a city park allows detecting, and it is not the state rule either. They are listed because their existence is the useful fact: if you are in a county park, a separate rule probably applies to you.

0 of these 1 name their county in the text that was read; the rest name only “county park” or “county parks”, so the source is given instead of a county name. A county is never inferred from a web address.

4. Cities checked - no published rule

89 cities in Michigan were checked and have no published rule on this page. Of those, 88 returned no rule, and 1 did return something that has not been published – mostly rules that turned out to govern county land, which are in the county section above. A city here is not a city where detecting is allowed. It is a city whose own published material did not answer the question.

All 89 were checked on 13 September 2026, in one sweep, so that date applies to every row. 1 has no municipal site recorded and is shown without a link rather than dropped, because dropping them would understate what was checked.

5. Land this page does not cover

This page answers for Michigan state land, and for city and county land where the state rule reaches it. Several other kinds of ground are not covered here, and naming them is more honest than letting a reader assume the page is complete.

Tribal land. This directory does not cover it, and will not.

There are 574 federally recognised tribal nations. Each is a sovereign jurisdiction with its own law, its own permitting, its own enforcement and its own cultural-resource provisions, and none of them is answered by a state's code or by any federal rule quoted on these pages. A one-line instruction to "get tribal permission" would be worse than this paragraph, because it implies one process and one authority where there are 574. If you are on or near tribal land, the governing law is that nation's, and the place to ask is that nation's own offices. Nothing on this page applies there.

BLM land is covered, partly, in its own place. The Bureau of Land Management holds about 245 million acres and the federal rule names metal detectors and permits them, which is the opposite of the national park rule. See BLM land: the detector is named, and permitted. That page covers the base regulation; it does not yet cover the supplementary rules individual BLM State Directors issue for particular field offices.

Named and not examined. These are recorded so their absence is visible rather than silent. No claim is made about any of them:

• Military withdrawn land, including ranges and training areas.
• Bureau of Reclamation land, which surrounds a great many reservoirs.
• Water district and irrigation district land.
• Wilderness, Wilderness Study Areas and National Conservation Areas, which carry designations of their own. And one general point about signs. The commonest piece of reasoning in this subject is "there was no sign, so it was allowed." Arizona's State Land Department answers it in writing, in condition 2 of its own Recreational Permit terms:

"You will comply with all laws, rules, regulations and ordinances. Posting is not required for these provisions to be enforceable."

That is Arizona's sentence about Arizona's provisions and this directory does not present it as the law of any other state. But the proposition it states is the one to carry: nothing read for this project makes a published rule's enforceability depend on a sign at the boundary. Where posting does matter, a specific provision says so, and that provision is quoted on the page where it occurs.
