Maryland Recording Law Summary:

In this state, it is a criminal offense to tape-record a conversation without the consent of all involved parties. Md. Code Ann., Cts. & Jud. Proc. § 10-402. This means that in Maryland you are not legally allowed to record a conversation you are taking part in unless all parties are in agreement. It is also forbidden to record someone with criminal or torturous intentions, and consent cannot be legally given in such situations.

However, Maryland law does make an exception in cases where the person or people communicating are doing so in an environment where they should not be under the expectation of privacy. For example, it is legal to record someone in a neighboring apartment if you can clearly hear them through the walls.
