        Re: Real Estate Investment Trust of California

Ladies and Gentlemen:

   
    We  have acted as  counsel for BRE Properties,  Inc., a Delaware corporation
("Parent"), and BRE Maryland,  Inc., a Maryland corporation  and a wholly  owned
subsidiary  of  Parent  (the  "Maryland  Subsidiary"),  in  connection  with the
Agreement and Plan of Merger,  dated as of October  11, 1995, among Parent  (for
itself  and on behalf of the  Maryland Subsidiary), Real Estate Investment Trust
of California,  a California  real  estate investment  trust ("RCT"),  and  Real
Estate   Investment  Trust  of  Maryland,  a   Maryland  business  trust  and  a
wholly-owned subsidiary of RCT (the "RCT  Subsidiary"), as amended by the  First
Amendment to Agreement and Plan of Merger dated as of December 21, 1995, and the
Second  Amendment to Agreement and  Plan of Merger dated  as of January 29, 1996
(the "Merger Agreement") pursuant to which (i) RCT will be merged with and  into
the  RCT Subsidiary, (ii) the RCT Subsidiary will be merged with and into Parent
(the "Parent  Merger"),  and (iii)  Parent  will be  merged  with and  into  the
Maryland  Subsidiary  (the "Reincorporation  Merger"). Unless  otherwise defined
herein, all capitalized words and phrases defined in the Merger Agreement  shall
have the same meanings when used herein.
    

    In  connection  with this  opinion, we  have  examined originals,  or copies
certified  or  otherwise  identified  to  our  satisfaction,  of  the  following
documents:

        (a)  Certified  copies  of  the  Amended  and  Restated  Certificate  of
    Incorporation and the Bylaws of Parent  as amended and restated to date  and
    the Articles of Incorporation and the Bylaws of the Maryland Subsidiary (the
    "Charter Documents");

        (b)  Resolutions adopted by the Board of Directors of Parent at meetings
    held on October 2,  1995, and January 29,  1996, and resolutions adopted  by
    the  Board  of Directors  of the  Maryland  Subsidiary by  unanimous written
    consent dated as of January 29,  1996, authorizing, among other things,  the
    transactions contemplated by the Merger Agreement;

   
        (c) Parent's registration statement on Form S-4 (File No. 33-65365) with
    respect  to the  shares of Parent  Common Stock  to be issued  in the Parent
    Merger and the shares of the Surviving Corporation Common Stock to be issued
    in the Reincorporation  Merger, filed  with the Commission  on December  22,
    1995,  as amended  by Pre-Effective  Amendment No. 1  filed with  the SEC on
    January 5, 1996,  and Pre-Effective Amendment  No. 2 filed  with the SEC  on
    February  1,  1996,  and all  exhibits  and appendices  to  the Registration
    Statement, and the Prospectus constituting a part thereof (such registration
    statement as  so  amended  at the  time  it  is declared  effective  by  the
    Commission,  and including  the documents incorporated  by reference therein
    and the information deemed to be a part thereof pursuant to Rule 430A(b)  of
    the   Rules  and   Regulations,  being   hereinafter  referred   to  as  the
    "Registration Statement"); and
    

        (d) Specimen certificates for the Surviving Corporation Common Stock.

    We have also examined originals or copies, certified or otherwise identified
to our satisfaction, of such records of Parent and the Maryland Subsidiary, such
agreements, certificates of public officials,

certificates of officers or representatives  of Parent, the Maryland  Subsidiary
and  others,  and  such  other documents,  certificates  and  records,  and have
conducted such further  investigation of  matters of fact  and law,  as we  have
deemed necessary or appropriate as a basis for the opinions set forth herein. As
to  any  facts  material  to  the  opinions  expressed  herein  which  were  not
independently established  or verified,  we  have relied  upon oral  or  written
statements  and representations of officers and other representatives of Parent,
the Maryland Subsidiary and others.

    In our  examination  we have  assumed  the  legal capacity  of  all  natural
persons,  the genuineness of  all signatures, the  authenticity of all documents
submitted to  us as  originals,  the conformity  to  original documents  of  all
documents   submitted  to  us  as  certified   or  photostatic  copies  and  the
authenticity  of  the  originals  of  such  latter  documents.  In  making   our
examination  of documents executed by parties  other than Parent or the Maryland
Subsidiary, we have assumed that such parties had the power, corporate or other,
to enter into and perform all  obligations thereunder and have also assumed  the
due  authorization by  all requisite action,  corporate or other,  and the valid
execution and  delivery by  such parties  of such  documents and  the  validity,
binding  effect  and  enforceability  thereof. We  also  have  assumed  that the
transactions related to the Parent Merger and the Reincorporation Merger will be
consummated in accordance  with the  Merger Agreement  and as  described in  the
Joint Proxy Statement and Prospectus.

   
    Subject  to the assumptions, limitations,  exceptions and qualifications set
forth herein, it is our opinion that (i) the shares of Parent Common Stock to be
issued pursuant to Parent Merger have been duly and validly authorized and, when
issued and delivered in  exchange for the shares  of beneficial interest of  RCT
issued  and outstanding immediately  prior to the Parent  Merger pursuant to the
Merger Agreement, will, upon the effectiveness of the Parent Merger, be  validly
issued,  fully  paid  and  non-assessable;  and  (ii)  the  shares  of Surviving
Corporation Common Stock  to be  issued pursuant to  the Reincorporation  Merger
have been duly and validly authorized and, when issued and delivered in exchange
for  the shares  of the Parent  Common Stock issued  and outstanding immediately
prior to the Reincorporation Merger pursuant to the Merger Agreement, will, upon
the effectiveness of the Reincorporation  Merger, be validly issued, fully  paid
and non-assessable.
    

    We  express no opinion herein concerning any laws other than the laws of the
State of California, the  General Corporation Law of  the State of Delaware  and
the General Corporation Law of the State of Maryland.

   
    We  assume no  obligation to supplement  this opinion if  any applicable law
changes after the  date hereof  or if  we become aware  of any  fact that  might
change  the opinions  expressed herein  after the  date hereof.  This opinion is
furnished to you solely for your benefit  in connection with the Merger and  may
not be quoted in full or in part or otherwise referred to, filed with, furnished
to,  or relied  upon by  any other  person or  entity, or  by you  for any other
purpose, with  or without  reference  to our  firm,  without the  prior  written
consent of this firm.
    

    We  hereby  consent to  the  filing of  this opinion  as  an exhibit  to the
Registration Statement and to the use of the name of our firm therein. In giving
this consent, we do not admit that  we are within the category of persons  whose
consent is required by Section 7 of the 1933 Act.

                                          Very truly yours,

   
                                          /S/  FARELLA BRAUN & MARTEL
