Banks are subject to separate and very specific regulations under Federal and state laws, so it is not analogous and does not carry the same risks. You are also granted specific possessory rights in the box itself; you aren't handing the contents to the bank and letting it do whatever with it. A separate warrant or court order is needed to enter the box. Leases are technically conveyances of an estate in land; the land becomes yours insofar as the authorities are concerned, which is why the cops need a separate warrant to enter each apartment. Storage lockers are much the same as leases; you are granted exclusive right to occupy the space, which is why the entry into and disposition of contents is highly controlled (see Storage Wars) and again, separate warrants needed.

AHs are just another business. Unlike the storage locker you are not granted an exclusive right to enter and use the space. You just hand over your stuff.
