I started watching AD at the end of the first season and was wondering if Roxanne's mom was ever shown. Just curious because I've never seen her mom. Isn't her grandmother also supposed to be living with them?

Yes, her mother was shown in the ifrst season but not lately.

I have not heard of any grandmother though!!

I remember when Lenny and Roxanne were leaving her apartment and Roxanne yelled back into the apartment that she was going out. She said it in Polish.

Roxanne's mom was showed a couple times in season 1......Her grandmother is there to except never shown......Plus they hardly show what goes on in Roxanne's household....which im guessing is why they hardly ever show her mom and never show her grandma.....Mel :D
