Wit One of the perks of owning a traditional home is the freedom you have to put decorations up, something that may be limited if you're living in Miami Beach condos.
Your decorations may differ depending on whether you celebrate Christmas, Hanukkah or something else. However, there was a time in South Florida when associations had the right to completely bar any kind of religious display in Miami Beach condos, a rule that has since been struck down. Nowadays residents can display these objects regardless of the time of the year.
You should know that although you're free to hang up your mezuzah or wreath to show your spirit or beliefs, associations can still put the kibosh on decorations that are not religious in nature or border on being too big and potentially obstructive. All condominium associations (Miami Beach condos included) have governing documents dictating what you can and cannot do. It wouldn't hurt to take a look at the rules just to be on the safe side without ruffling anyone's feathers.
