Massachusetts is friendly to beach detectorists: DCR sandy beaches are open without any permission. Off the beach, though, it’s a different rule — you need the park supervisor’s OK, and only to find lost property. Add a strong antiquities law and the quirky Colonial-era private-beach doctrine, and here’s the full picture.
At a glance
| State parks | Allowed* On DCR land, detecting is allowed without permission only on coastal and inland sandy beaches; elsewhere it needs park-supervisor permission and only to recover lost personal property. |
|---|---|
| State & public land | Restricted The Massachusetts Antiquities Act (M.G.L. c.9 §§26–27C) bars field investigation on Commonwealth land without a State Archaeologist permit; violations are a misdemeanor and finds are forfeited. |
| Beaches | Depends DCR coastal and inland sandy beaches are open without special permission; many private tidal-flat beaches are owned to low water under the 1641 Colonial Ordinance. |
| Local & federal | Depends Cities and towns set their own rules (many require a permit or ban detecting). |
*Even where detecting is allowed, archaeological/historic sites are protected and you must fill holes and follow posted rules. Always confirm the current rule with the specific land manager.
Metal detecting in Massachusetts state parks
Department of Conservation and Recreation (DCR) land is governed by 302 CMR 12.04. Detecting is allowed without permission only on coastal and inland sandy beaches. Everywhere else on DCR land, using a detector requires permission from DCR personnel (the park supervisor) and only to recover lost personal property — general relic or treasure hunting isn’t covered.
Massachusetts’s antiquities law
The Massachusetts Antiquities Act (M.G.L. c.9 §§26–27C) prohibits “field investigation” on land owned or controlled by the Commonwealth without a permit from the State Archaeologist; violations are a misdemeanor (up to $500 or 6 months) and any finds are forfeited to the Commonwealth.
Beaches, private land & local rules
DCR coastal and inland sandy beaches are open without special permission. Be aware of the 1641/47 Colonial Ordinance: many Massachusetts beaches are privately owned all the way to the low-water mark, where only fishing, fowling, and navigation are public rights — detecting is not a protected public right on private tidal flats. Cities and towns set their own rules (many require a permit or ban detecting), and digging on state land still triggers the c.9 permit requirement. See our national guide.

Frequently Asked Questions
- Can you metal detect on a Massachusetts state-park beach?
- Yes — under 302 CMR 12.04, coastal and inland sandy DCR beaches are exempt from the permission requirement, so you may detect there without a special permit. Non-DCR (town or private) beaches may restrict or prohibit it.
- Do you need permission to detect in a Massachusetts state park away from the beach?
- Yes. Off the sandy beach on DCR land, detector use requires the park supervisor’s permission and only to locate lost personal property; general relic or treasure hunting is not covered.
- Is there a Massachusetts law about digging up historic items?
- Yes — the Massachusetts Antiquities Act (c.9 §§26–27C) bars field investigations on Commonwealth-owned or -controlled land without a State Archaeologist permit; violations are a misdemeanor and finds are forfeited to the state.
