The Medina County Board of Elections is located down the road to the North of the Hobby Lobby / Walmart plaza (Stonegate Drive). It’s on the south side of Stonegate Drive, in a little strip-mall looking plaza.
The mail-in ballot drop-box is located to the right of their door. There are two envelopes you need to use. One that you sign & put personal info on — that needs to go into the outer mailing envelope (aka privacy envelope) even if you’re not actually mailing the ballot. You can drop off your ballots any time — slide the envelope into the slot, so you don’t have to touch anything except your ballot.
