Permit Office
3201 Boston St
Baltimore, MD 21224. (one story building on the water - knock if door is locked)
Phone: 410-396-7070.
The office is closed Thursday - Open Mon, Tues, Wed and Friday 9am-4pm.

The office is closed Thursdays Open Mon, Tues, Wed and Friday 9-4, but the permit office seems to open around 9:30 AM. It is best to walk into the building to get your permit. Often it is issued the same day. Snail mail is really slow.

Note on the older green permanent permit card without an expiration date: The lack of expiration date does not mean the permit is good forever and there is no "grandfather clause" that allows a liftime deferal.

Proof of yearly renewal, such as a receipt, must be carried while metal detecting in city parks. You do not need this receipt if your permit card has an expiraton date on it.

State Park Rules - NO DETECTING -

     Please contact your local County Council by (preferably) letter, email, or in person. Try to convince them that clad coins and trash are not illegal archaeological artifacts. Explain digging techniques. Also argue that future development will bury or redistribute these so-called "archaeological artifacts" forever. Be polite.
