                            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, 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 report;

4.       The  registrant's  other  certifying  officer and I are responsible for
         establishing  and  maintaining  disclosure  controls and procedures (as
         defined  in  Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  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)    [paragraph omitted pursuant to SEC Release Nos. 33-8238 and
                34-47986]

         c)    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

         d)    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 reporting; and

5.       The registrant's other certifying  officer 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.
