    Size Disclaimer

    Storage units at each of our self-storage facilities may vary in size and/or shape and are approximate to the unit size that we advertise as rentals. We recommend customers to ask to inspect the actual unit that they will be renting before they sign the rental agreement to ensure what they are receiving fits their needs and not based off of the unit size from the advertisement. The amount for the rental, whether it is for a general or specific unit,is not based off of the measurements of the square footage of the unit.
