            Re: Registration Statement on Form S-8:
             1998 Equity
Participation Plan___________________
 
Ladies and Gentlemen:
 
     We have served as Maryland counsel to Kimco Realty Corporation, a Maryland
corporation (the 'Company'), in connection with certain matters of Maryland law
arising out of the registration of 3,000,000 shares (the 'Shares') of Common
Stock, $.01 par value per share, of the Company ('Common Stock') covered by the
above-referenced Registration Statement (the 'Registration Statement'), under
the Securities Act of 1933, as amended (the '1933 Act'). The Shares are to be
issued by the Company pursuant to the Company's 1998 Equity Participation Plan
(the 'Plan'). Capitalized terms used but not defined herein shall have the
meanings given to them in the Registration Statement.
 
     In connection with our representation of the Company, and as a basis for
the opinion hereinafter set forth, we have examined originals, or copies
certified or otherwise identified to our satisfaction, of the following
documents (hereinafter collectively referred to as the 'Documents'):
 
           1. The Registration Statement, filed with the Securities and Exchange
     Commision (the 'Commission'), pursuant to the Securities Act of 1933, as
     amended (the '1933 Act'), and the related form of prospectus in the form in
     which it will be sent or given to employees of the Company in accordance
     with Rule 428(b)(1) under the 1933 Act;
 
           2. The charter of the Company (the 'Charter'), certified as of a
     recent date by the State Department of Assessments and Taxation of Maryland
     (the 'SDAT');
 
           3. The Bylaws of the Company, certified as of a recent date by its
     Secretary;
 
           4. Resolutions adopted by the Board of Directors of the Company
     relating to (i) the approval of the Plan and (ii) the issuance and
     registration of the Shares, certified as of a recent date by the Secretary
     of the Company;
 
           5. Resolutions adopted by the stockholders of the Company relating to
     the approval of the Plan, certified as of recent date by the Secretary of
     the Company;
 
           6. A specimen of the certificate representing a share of Common
     Stock, certified as of a recent date by the Secretary of the Company;
 
           7. A certificate of the SDAT as to the good standing of the Company,
     dated as of a recent date;
 
           8. A certificate executed by the Secretary of the Company, dated the
     date hereof;
 
           9. The Plan; and
 
          10. Such other documents and matters as we have deemed necessary or
     appropriate to express the opinion set forth in this letter, subject to the
     assumptions, limitations and qualifications stated herein.
 
     In expressing the opinion set forth below, we have assumed, and so far as
is known to us there are no facts inconsistent with, the following:
 
                                       8

          1. Each individual executing any of the Documents whether on behalf of
     such individual or another person, is legally competent to do so.
 
          2. Each individual executing any of the Documents on behalf of a party
     (other than the Company) is duly authorized to do so.
 
          3. Each of the parties (other than the Company) executing any of the
     Documents has duly and validly executed and delivered each of the Documents
     to which such party is a signatory, and such party's obligations set forth
     therein are legal, valid and binding and are enforceable in accordance with
     all stated terms.
 
          4. All Documents submitted to us as originals are authentic. All
     Documents submitted to us as certified or photostatic copies conform to the
     original documents. All signatures on all such Documents are genuine. All
     public records reviewed or relied upon by us or on our behalf are true and
     complete. All statements and information contained in the Documents are
     true and complete. There has been no oral or written modification or
     amendment to the Documents, or waiver of any of the provisions of any of
     the Documents, by action or omission of the parties or otherwise.
 
          5. The Shares will not be issued in violation of any restriction or
     limitation contained in Article VII of the Charter.
 
     The phrase 'known to us' is limited to the actual knowledge, without
independent inquiry, of the lawyers at our firm who have performed legal
services in connection with the issuance of this opinion.
 
     Based upon the foregoing, and subject to the assumptions, limitations and
qualifications stated herein, it is our opinion that:
 
          1. The Company is a corporation duly incorporated and existing under
     and by virtue of the laws of the State of Maryland and is in good standing
     with the SDAT.
 
          2. The Shares have been duly authorized for issuance pursuant to the
     Plan and, when and if issued and delivered against payment therefor in the
     manner described in the Plan, will be (assuming that upon any such issuance
     the total number of shares of Common Stock issued and outstanding will not
     exceed the total number of shares of Common Stock that the Company is then
     authorized to issue under the Charter) validly issued, fully paid and
     nonassessable.
 
     The foregoing opinion is limited to the substantive laws of the State of
Maryland and we do not express any opinion herein concerning any other law. We
express no opinion as to compliance with the securities (or 'blue sky') laws or
the real estate syndication laws 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 opinion expressed herein after the date hereof.
 
     This opinion is being furnished to you for submission to the Securities and
Exchange Commission as an exhibit to the Registration Statement and,
accordingly, may not be relied upon by, quoted in any manner to, or delivered to
any other person or entity without, in each instance, our prior written consent.
 
     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,

                                          Ballard Spahr Andrews & Ingersoll, LLP
 
                                       9
