partnership interest in EOP Operating Limited Partnership, if and to the extent
that the selling shareholders redeem their units and we issue them common shares
in exchange. The registration of the shares does not necessarily mean that any
of the shares will be offered or sold by the selling shareholders. Although we
will incur expenses in connection with the registration of these shares, we will
not receive any cash proceeds if they are sold.

    The common shares are listed on the New York Stock Exchange under the symbol

    The selling shareholders may from time to time offer and sell all or a
portion of the offered shares in transactions on the NYSE or any other national
securities exchange or quotation service on which the offered shares are listed
or quoted at the time of the sale, in the over-the-counter market, in negotiated

any agents or broker-dealers and applicable commissions or discounts and any
other required information with respect to any particular offer will be set
forth in this prospectus under the caption "Plan of Distribution" or in any
accompanying prospectus supplement. The selling shareholders reserve the right
to accept or reject, in whole or in part, any proposed purchase of the offered
shares to be made directly or through agents. The selling shareholders and any
agents or broker-dealers participating in the distribution of the offered shares
may be deemed to be "underwriters" within the meaning of the Securities Act of
1933, and any profit on the sale of offered shares by the selling shareholders
and any commissions received by any agents or broker-dealers may be deemed to be
underwriting commissions or discounts under the Securities Act.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

    Information contained in or incorporated by reference into this prospectus
and any accompanying prospectus supplement contains "forward-looking statements"
within the meaning of Section 27A of the Securities Act. We intend the
forward-looking statements to be covered by the safe harbor provisions for
forward-looking statements contained in Section 27A of the Securities Act. These
forward-looking statements relate to, without limitation, future economic
performance, our plans and objectives for future operations and projections of
revenue and other financial items, which can be identified by the use of
forward-looking terminology such as "may," "will," "should," "expect,"
"anticipate," "estimate" or "continue" or the negative thereof or other
variations thereon or comparable terminology. The cautionary statements
incorporated by reference from our 1998 Annual Report on Form 10-K under the
caption "Risk Factors" and other similar statements contained in this prospectus
or any accompanying prospectus supplement identify important factors with
respect to such forward-looking statements, including certain risks and
uncertainties, that could cause actual results to differ materially from those
in such forward-looking statements.

                                  THE COMPANY

    Equity Office was formed to continue and expand the national office property
business organized by Samuel Zell, our Chairman of the Board. Equity Office, a
real estate investment trust, is the managing general partner of, and controls a
majority of the limited partnership interests in, EOP Operating Limited
Partnership. We own all of our assets and conduct substantially all of our
business through EOP Operating and its subsidiaries.

    Our principal executive offices are located at Two North Riverside Plaza,
Suite 2200, Chicago, Illinois 60606, and our telephone number is (312) 466-3300.
We maintain regional offices in Los Angeles, Denver, Houston, Chicago, Atlanta
and Washington, D.C.

                           NO PROCEEDS TO THE COMPANY

    Equity Office will not receive any of the proceeds from sales of shares by
the selling shareholders. Most of the costs and expenses incurred in connection
with the registration under the Securities Act of the offered shares will be
paid by Equity Office. The selling shareholders will pay any brokerage fees and
commissions, fees and disbursements of legal counsel for the selling
shareholders and share transfer and other taxes attributable to the sale of the
offered shares.

                              SELLING SHAREHOLDERS

    The selling shareholders received their offered shares pursuant to
transactions relating to the formation of Equity Office in 1997. Equity Office
may issue 20,021,720 of the offered shares to selling shareholders holding up to
20,021,720 units of limited partnership interest in EOP Operating if the selling
shareholders redeem their units and we issue them common shares in exchange. The
following table provides the name of each selling shareholder, the number of
common shares owned by each selling shareholder before the offering to which
this prospectus relates, and the number of shares offered by each selling
shareholder. As used in this prospectus, the term "selling shareholder" also
includes transferees, assignees, distributees or pledgees of any person
identified as a selling shareholder. Except as the footnotes to the table below
indicate, the number of shares offered by a selling shareholder represent common
shares that Equity Office may issue on redemption of the selling shareholder's
units. Since the selling shareholders may sell all, some or none of their
shares, Equity Office cannot estimate the number of shares that will be sold by
the selling shareholders or that will be owned by the selling shareholders upon
completion of the offering. The offered shares represent approximately 4.0% of
the total number of Equity Office's common shares, assuming redemption of all
outstanding units for common shares, outstanding as of July 30, 1999.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Title 8 of the Corporations and Associations Article of the Annotated Code
of Maryland, as amended from time to time (the "Maryland REIT Law"), permits a
Maryland REIT to include in its declaration of trust a provision limiting the
liability of its trustees and officers to the trust and its shareholders for
money damages except for liability resulting from (a) actual receipt of an
improper benefit or profit in money, property or services or (b) active and
deliberate dishonesty established by a final judgment as being material to the
cause of action. The Company's declaration of trust, as amended from time to
time, and as filed with the State Department of Assessments and Taxation of
Maryland (the "Declaration of Trust"), contains such a provision which
eliminates such liability to the maximum extent permitted by the Maryland REIT
law.

    The Declaration of Trust authorizes the Company, to the maximum extent
permitted by Maryland law, to obligate itself to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
(a) any present or former trustee or officer or (b) any individual who, while a
trustee of the Company and at the request of the company, serves or has served
as a director, officer, partner, trustee, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or any
other enterprise from and against any claim or liability to which such person
may become subject or which such person may incur by reason of his or her status
as a present or former trustee or officer of the Company. The Bylaws obligate
the Company, to the maximum extent permitted by Maryland law, to indemnify and
to pay or reimburse reasonable expenses in advance of final disposition of a
proceeding to (a) any present or former trustee or officer who is made party to
the proceeding by reason of his service in that capacity or (b) any individual
who, while a trustee or officer of the Company and at the request of the
Company, serves or has served another corporation, partnership, joint venture,
trust, employee benefit plan or any other enterprise as a trustee, director,
officer or partner of such corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise and who is made a party to the
proceeding by reason of his service in that capacity, against any claim or
liability to which he may become subject by reason of such status. The
Declaration of Trust and Bylaws also permit the Company to indemnify and advance
expenses to any person who served a predecessor of the Company in any of the
capacities described above and to any employee or agent of the Company or a
predecessor of the Company. The Bylaws require the Company to indemnify a
trustee or officer (or any former trustee or officer) who has been successful,
on the merits or otherwise, in the defense of any proceeding to which he is made
a party by reason of his service in that capacity against reasonable expenses
incurred in connection with the proceeding.

    The Maryland REIT Law permits a Maryland REIT to indemnify and advance
expenses to its trustees, officers, employees and agents to the same extent as
permitted by the Maryland General

                                      II-1
<PAGE>
Corporation Law, as amended from time to time (the "MGCL"), for directors and
officers of Maryland corporations. The MGCL permits a corporation to indemnify
its present and former directors and officers, among others, against judgments,
penalties, fines, settlements and reasonable expenses actually incurred by them
in connection with any proceeding to which they may be made a party by reason of
their service in those or other capacities unless it is established that (a) the
act or omission of the director or officer was material to the matter giving
rise to the proceeding and (i) was committed in bad faith or (ii) was the result
of active and deliberate dishonesty, (b) the director or officer actually
received an improper personal benefit in money, property or services or (c) in
the case of any criminal proceeding, the director or officer had reasonable
cause to believe that the act or omission was unlawful. The foregoing
limitations on indemnification are expressly set forth in the Bylaws. However,
under the MGCL, a Maryland corporation may not indemnify for any adverse
judgment in a suit by or in the right of the corporation or for a judgment of
liability on the basis that a personal benefit was improperly received, unless,
in either case, a court orders indemnification and then only for expenses. Under
the MGCL, as a condition to advancing expenses, as required by the Bylaws, the
Company must first receive (a) a written affirmation by the trustee or officer
of his good faith belief that he has met the standard of conduct necessary for
indemnification by the Company and (b) a written undertaking by or on his behalf
to repay the amount paid or reimbursed by the Company if it shall ultimately be
determined that the standard of conduct was not met. In addition, Mr. Dobrowski,
a trustee of the Company, will be indemnified by General Motors Investment
Management Corporation ("GMIMCO") and will be covered by an insurance policy
maintained by General Motors Corporation, of which GMIMCO is a subsidiary, in
connection with serving on the Board.

    The limited partnership agreement of the Operating Partnership (the
"Partnership Agreement") also provides for indemnification of the Company and
its officers and trustees to the same extent that indemnification is provided to
officers and trustee of the Company in its Declaration of Trust, and limits the
liability of the Company and its officers and trustees to the Operating
Partnership and its respective partners to the same extent that the Declaration
of Trust limits the liability of the officers and trustees of the Company to the
Company and its shareholders.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to trustees, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Act and is therefore unenforceable.

ITEM 17.  UNDERTAKINGS

(a) The undersigned Registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:

        (i) To include any prospectus required by Section 10(a)(3) of the
            Securities Act of 1933;

        (ii) To reflect in the prospectus any facts or events arising after the
             effective date of the registration statement (or the most recent
             post-effective amendment thereof) which, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in this registration statement. Notwithstanding the
             foregoing, any increase or decrease in volume of securities offered
             (if the total dollar value of securities offered would not exceed
             that which was registered) and any deviation from the low or high
             end of the estimated maximum offering range may be reflected in the
             form of prospectus filed with the Commission pursuant to Rule
             424(b) if, in the aggregate, the changes in volume and price
             represent no more than a 20 percent change in the maximum aggregate
             offering price set forth in the "Calculation of Registration Fee"
             table in the effective registration statement; and

       (iii) To include any material information with respect to the plan of
             distribution not previously disclosed in the registration statement
             or any material change to such information in this registration
             statement;

    PROVIDED, HOWEVER, that subparagraphs (i) and (ii) above shall not apply if
    the information required to be included in a post-effective amendment by
    those paragraphs is contained in the periodic reports filed with or
    furnished to the Commission by the Registrant pursuant to Section 13 or
    Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
    by reference in this registration statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the Securities offered
    herein, and the offering of such Securities at that time shall be deemed to
    be the initial bona fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
    any of the Securities being registered which remain unsold at the
    termination of the offering.

    (b) The undersigned Registrant hereby further undertakes that, for the
purposes of determining any liability under the Securities Act of 1933, each
filing of the Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in this registration statement shall be deemed to be a new registration
statement relating to the Securities offered herein, and the offering of such
Securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.

    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to existing provisions or arrangements whereby the
Registrant may indemnify a director, officer or controlling person of the
Registrant against liabilities arising under the Securities Act of 1933, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Registrant

                                      II-3
<PAGE>
of expenses incurred or paid by a director, officer or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

                                   SIGNATURES

    Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Chicago, Illinois, on this 26th day of August, 1999.

Board of Trustees
Equity Office Properties Trust
Two North Riverside Plaza
Suite 2200
Chicago, Illinois  60606

Ladies and Gentlemen:

     We are acting as counsel to Equity Office Properties Trust, a Maryland
real estate investment trust (the "Company"), in connection with its
registration statement on Form S-3 (the "Registration Statement") filed with
the Securities and Exchange Commission relating to proposed resales of up to
21,545,034 of the Company's common shares of beneficial interest, $.01
par value per share ("Common Shares"), 20,021,720 of which Common Shares
may be issued at the Company's election in private placements if and to the
extent that holders of 20,021,720 units of limited partnership interest in
EOP Operating Limited Partnership ("Units") tender such Units for redemption,
all of which Common Shares are to be sold by or on behalf of certain
shareholders of the Company.  This opinion letter is furnished to you at your
request to enable the Company to fulfill the requirements of Item 601(b)(5)
of Regulation S-K, 17 C.F.R. Section 229.601(b)(5), in connection with the
Registration Statement.

     For purposes of this opinion letter, we have examined copies of the
following documents:

     1.  An executed copy of the Registration Statement.

     2.  The Articles of Amendment and Restatement of Declaration of Trust of
         the Company, as certified by the Maryland State Department of
         Assessments and Taxation on June 16, 1999 and by the Assistant
         Secretary of the Company on the date hereof as then being complete,
         accurate and in effect.

     3.  The Bylaws of the Company, as certified by the Assistant Secretary
         of the Company on the date hereof as then being complete, accurate
         and in effect.

     4.  The Certificate of Limited Partnership of EOP Operating Limited
         Partnership (the "Operating Partnership"), as certified by the
         Secretary of State of the State of Delaware on November 25, 1998,
         and certified as of the date hereof by the Assistant Secretary of
         the Company, in its capacity as managing general partner of the
         Operating Partnership, as then being complete, accurate and in
         effect.

     5.  The Agreement of Limited Partnership of the Operating Partnership,
         dated as of July 3, 1997, as amended, as certified as of the date
         hereof by the Assistant Secretary of the Company, in its capacity as
         managing general partner of the Operating Partnership, as then being
         complete, accurate and in effect (the "Partnership Agreement").

     6.  An executed copy of the Registration Rights Agreement dated as of
         July 11, 1997 by and among the Company and the Persons Listed on the
         Signature Pages thereto (the "Registration Rights Agreement").

     7.  Resolutions of the Board of Trustees of the Company, for itself and
         as managing general partner of the Operating Partnership, adopted on
         May 5, 1997, as certified by the Assistant Secretary of the Company
         on the date hereof as then being complete, accurate and in effect,
         relating to the original issuance of the Units, the execution and
         delivery of the Transaction Documents, the preparation and filing of
         the Registration Statement and arrangements in connection therewith.

     8.  A certificate of the Assistant Secretary of the Company dated August
         27, 1999.

     In our examination of the aforesaid certificates and documents, we have
assumed the genuineness of all signatures, the legal capacity of natural
persons, the accuracy and completeness of all documents submitted to us, the
authenticity of all original documents and the conformity to authentic
original documents of all documents submitted to us as copies (including
telecopies).  We

also have assumed that the Common Shares will not be issued in violation of
the ownership limit contained in the Company's Declaration of Trust.  This
opinion letter is given, and all statements herein are made, in the context
of the foregoing.

     This opinion letter is based as to matters of law solely on applicable
provisions of Maryland law.  We express no opinion as to any other laws,
statutes, ordinances, rules or regulations or as to compliance with the
securities (or "blue sky") laws, rules or regulations or the real estate
syndication laws of Maryland.

     Based upon, subject to and limited by the foregoing, we are of the
opinion that the Common Shares, if and when issued and delivered in
accordance with the terms of the Partnership Agreement and appropriate
resolutions of the Board of Trustees of the Company authorizing the issuance
of the Common Shares upon redemption of the Units as contemplated thereby,
will be validly issued, fully paid and nonassessable under the laws of the
State of Maryland.  In rendering the foregoing opinion, we have assumed the
receipt by the Operating Partnership of the consideration specified in the
resolutions of the Board of Trustees of the Company, as managing general
partner of the Operating Partnership, authorizing the original issuance and
sale of the Units.

     This opinion letter has been prepared for your use in connection with
the Registration Statement and speaks as of the date hereof.  We assume no
obligation to advise you of any changes in the foregoing subsequent to the
delivery of this opinion letter.

     We hereby consent to the filing of this opinion letter as Exhibit 5.1 to
the Registration Statement.  In giving this consent, we do not thereby admit
that we are an "expert" within the meaning of the Securities Act of 1933, as
amended.

                                          Very truly yours,


                                          /s/ Hogan & Hartson L.L.P.
