Several key factors should help you decide this, including market demand, the size of the storage units you plan to offer, and the size of your land parcel itself.
Let’s say you’re working with a 2-acre property, which spans about 87,120 square feet. For example, if you’re looking to offer each renter a 10’x15’ storage unit, which is a popular mid-range unit size, you can reasonably fit about 100 storage units on your land.
While a 2-acre plot of land has about 87,120 square feet, not all of it can accommodate storage units. You also need to designate space on the property for driving, parking, fencing, stormwater runoff, and so on. The actual amount of space on your property occupied by storage units is your “coverage rate,” and most self-storage businesses have coverage rates that fall somewhere between 30% and 50%.
