According to Self Storage Auctions, a website, there isn't really a good centralized source for this information. You need to call each storage place and check with them. There's some info here: http://www.storageauctions.com/3.htm

Self Storage Auctions are a great money making idea. You can get auction information at www.auctionzip.com.
Silver Star Self Storage sometimes has auctions. Contact them at 3043 North Pecos Road, N. Las Vegas, NV - (702) 399-4550 One site listing some Las Vegas auctions is http://storageauctions.tripod.com/ (this is an auction house). http://www.auctionzip.com/nv.html lists a number of different auctions in Nevada, including self storage.
Finding your storage company's auctions depends on its location. You can try to locate their auctions by visiting http://www.auctionzip.com/. Self storage sales have to be advertised in the local newspapers more than once to satisfy county requirements. It will list the original name of the owner. An owner can retreive his property if he pays the fee before the auction starts.
The law requires that self storage auctions and dates must be published in the newspaper for two consecutive dates. The auction must then be at least seven days after the second week of publication. This can only occur if the owner of the storage unit has notified the person who has not paid that the unit will be sold. The owner must wait 2 weeks before putting the items in the unit up for auction in the newspaper.
You can search for storage auctions in your area online. Using your zip code, you can find upcoming auctions with the dates, times and addresses listed. I did a search for 29401 and four results came up. Not sure if that is the zip you are wanting to use though, so check it out for yourself.
Check the BLM website for auction dates, they also have online auctions as well.
