You’ve seen them, I know you have. They pop up everywhere, as if by magic: Bandit Signs. They usually say “WE BUY HOUSES” or something similar, with a phone number — no company name, just the statement and a phone number, maybe a tag line.

In both Baltimore City and Baltimore County, they’re illegal — my guess is in most municipalities they’re illegal. At the very least, they’re an eyesore and add additional blight to neighborhoods that can ill afford even more blight.
I would like to invite you to join in my campaign to rid our neighborhoods of these signs. If you see them in the public right-of way — light poles, street signs, etc. Or if you see them posted to a vacant home — rip them down and throw them into the trash! Or use them for a creative art project. (Just don’t trespass on someone else’s property.)
Many thanks to @vees for providing the text of the Baltimore County and City codes regarding signage. You can read the full text here. (Link opens a PDF).
Oh, and if you do happen to do something creative with them — send me a photo and I’ll post them!
