                    CERTIFICATION OF CEO AND CFO 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  annual  report  on  Form  10-K  of  Public  Storage
     Properties, Ltd.;

2.   Based on my  knowledge,  this  annual  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 year-end report;

3.   Based on my  knowledge,  the  financial  statements,  and  other  financial
     information  included  in  this  year-end  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
     annual 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-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
        year-end report is being prepared;

     b) evaluated the effectiveness of the registrant's  disclosure controls and
        procedures  and  presented  in this  report  our  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  during 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  officers and I have disclosed,  based on
     our most recent evaluation of internal  controls over financial  reporting,
     to the registrant's  auditors and the audit committee of registrant's board
     of directors:

     a) all significant  deficiencies  and material  weaknesses in the design or
        operation  of  internal  controls  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
        controls over financial reporting.
