Trespassing

Perhaps one of the most easily broken laws, trespassing is entering another person's property without permission. 

Trespassing is a crime under Ohio Revised Code 2911.21, and is typically a fourth-degree misdemeanor.  

More specifically, criminal trespassing involves intentionally entering or remaining on

someone else's property without authorization. This means that accidentally entering your neighbor's lawn is not criminal trespassing (unless there is a clear fence or sign indicating no entry).

"Even if you are allowed to enter a place that's open to the public , you can still be convicted of criminal trespass if you stay after the space closes or fail to leave after you're ordered to do so"

This means entering a park after it has already closed (typically indicated by a sign) is a crime. Failing to leave a store after being asked to is a crime as well.
