Estimate the real space requirement
List the large items and number of boxes you expect to store, then compare unit dimensions rather than only square-foot labels. Ask whether ceilings, doors, columns or irregular shapes reduce usable space and whether staff can show the actual unit type.
Compare access and building features
Check gate or building access hours, elevator availability, loading areas, carts, lighting, climate-control conditions and whether the unit is indoors or drive-up. If you need frequent access, operating convenience may matter more than the lowest introductory rate.
Read the complete pricing terms
Ask about administration fees, lock requirements, deposits, insurance requirements, promotional end dates, future rate changes and notice needed to move out. A low first-month price can be misleading if the ongoing rate is not clear.
Know what cannot be stored
Facilities restrict hazardous, illegal, perishable or other items. Review the current rental rules and insurance terms directly before moving belongings into the unit.
