2,546 office parks operated by PS Business Parks, which Public Storage owns a 42 percent interest in. The largest self-storage business in Canada is operated by a separate company that is allowed to use the Public Storage brand.

For example, claims have been denied because the storage unit had an intact lock; affiliated insurance companies cited insufficient evidence of forced entry, though burglars often replace the unit's lock in an attempt to conceal the burglary. Insurance commissioners in two states have criticized the
