The typical issue with basements is moisture, especially in the summer/humid months. That moisture can lead to a 'musty' smell. If you use a dehumidifer and keep stuff off the floor, you should be OK. Here are the specs of the room I use for storage: Basement room with no direct heat. (Forced air heating is only upstairs in my house) 100% light free (window covered with room-darkening blinds and door shut), except when I am in it Dehumidifier running non-stop in the summer to remove as much moisture as possible Carpeted (This helps keep the moisture away from the Lego I store on shelves. I do not place anything on the carpet itself except for storage totes that are used to store Ziploc-sealed lots of polybags. I do also keep a couple DampRid-style jugs around the room. I use these personally to non-scientifically judge the moisture level in the air. They essentially grab moisture from the air and pull it into a container. If they are collecting a lot of moisture, I adjust the settings on my dehumidifier.
