                            CERTIFICATION PURSUANT TO
                             18 U.S.C. SECTION 1350,
                             AS ADOPTED PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


I, Ronald L. Havner, Jr., certify that:

   1.  I have  reviewed  this  quarterly  report on Form 10-Q of Public  Storage
       Properties IV, Ltd.;

   2.  Based on my knowledge,  this quarterly report does not contain any untrue
       statement of a material fact or omit to state a material  fact  necessary
       to make the statements  made, in light of the  circumstances  under which
       such  statements  were made,  not  misleading  with respect to the period
       covered by this report;

   3.  Based on my knowledge,  the  financial  statements,  and other  financial
       information  included  in this  report,  fairly  present in all  material
       respects the financial condition, results of operations and cash flows of
       the  registrant as of, and for, the periods  presented in this  quarterly
       report;

   4.  The  registrant's  other  certifying  officers and I are  responsible for
       establishing  and  maintaining  disclosure  controls and  procedures  (as
       defined in Exchange Act Rules 13a-14 and 15d-14) for the  registrant  and
       we have:

       a)designed  such  disclosure  controls  and  procedures,  or caused  such
         disclosure controls and procedures to be designed under our supervision
         to  ensure  that  material  information  relating  to  the  registrant,
         including its consolidated subsidiaries,  is made known to us by others
         within  those  entities,  particularly  during the period in which this
         report is being prepared;

       b)evaluated the effectiveness of the registrant's disclosure controls and
         procedures  and  presented  in  this  report   conclusions   about  the
         effectiveness  of the disclosure  controls and procedures as of the end
         of the period covered by this report based on such evaluation; and

       c)disclosed  in this  report  any  change  in the  Registrant's  internal
         control over financial  reporting that occurred the  Registrant's  most
         recent fiscal  quarter (the  Registrant's  fourth fiscal quarter in the
         case  of  an  annual  report)  that  has  materially  affected,  or  is
         reasonably  likely  to  materially  affect  the  registrant's  internal
         control over financial reports; and

   5.  The registrant's other certifying officers and I have disclosed, based on
       our most recent evaluation of internal control over financial  reporting,
       to the  registrant's  auditors and the audit  committee  of  registrant's
       board of directors (or person performing the equivalent functions):

       a)all significant  deficiencies and material  weaknesses in the design or
         operation  of  internal  control  over  financial  reporting  which are
         reasonably  likely to  adversely  affect  the  registrant's  ability to
         record, process, summarize and report financial information; and

       b)any fraud,  whether or not material,  that involves management or other
         employees  who have a  significant  role in the  registrant's  internal
         control over financial reporting.
