We are acting as tax counsel to Parkway, Inc., a Maryland corporation (the “Company”), in connection with its registration statement on Form S-11, as amended (the “Registration Statement”), filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), relating to the offer and sale from time to time by the selling stockholders identified in the Registration Statement of up to 6,246,216 shares of common stock, $0.001 par value per share (the “Common Stock”), of the Company (the “Shares”), which consists of (i) 4,821,416 Shares (the “TPG Shares”) that were received by TPG VI Pantera Holdings, L.P. and TPG VI Management, LLC, collectively, in the distribution by Cousins Properties Incorporated (“Cousins”) of the outstanding Common Stock of the Company on October 7, 2016, pursuant to that certain Agreement and Plan of Merger, dated as of April 28, 2016, by and among Parkway Properties, Inc., Parkway Properties LP (“Parkway LP”), Cousins and Clinic Sub Inc., a wholly owned subsidiary of Cousins, and that certain Separation, Distribution and Transition Services Agreement, dated as of October 5, 2016, by and among the Company, Cousins, Parkway LP and certain other parties (the “Distribution Agreement”), (ii) 1,020,862 Shares (the “Redemption Shares”) that, from time to time, the Company may issue to the holders of limited partnership units in Parkway LP (“OP Units”) upon the tender of OP Units for redemption in accordance with the Second Amended and Restated Agreement of Limited Partnership of Parkway LP, dated as of February 27, 2013, as amended (the “Partnership Agreement”), and (iii) 403,938 Shares (the “Thomas Affiliate Shares”) that are held by persons who may be deemed affiliates of the Company, in each case, as well as any of their permitted transferees, pledgees, donees, assignees, successors, and others who later come to hold any of the Shares other than through a public sale.

Bases for Opinions

The opinions set forth in this letter are based on relevant current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations thereunder (including proposed and

temporary Treasury Regulations), and interpretations of the foregoing as expressed in court decisions, applicable legislative history, and the administrative rulings and practices of the Internal Revenue Service (the “IRS”), including its practices and policies in issuing private letter rulings, which are not binding on the IRS except with respect to a taxpayer that receives such a ruling, all as of the date hereof. These provisions and interpretations are subject to change by the IRS, Congress and the courts (as applicable), which may or may not be retroactive in effect and which might result in material modifications of our opinions. Our opinions do not foreclose the possibility of a contrary determination by the IRS or a court of competent jurisdiction, or of a contrary position taken by the IRS or the Treasury Department in regulations or rulings issued in the future. In this regard, an opinion of counsel with respect to an issue represents counsel’s best professional judgment with respect to the outcome on the merits with respect to such issue, if such issue were to be litigated, but an opinion is not binding on the IRS or the courts, and is not a guarantee that the IRS will not assert a contrary position with respect to such issue or that a court will not sustain such a position asserted by the IRS. Terms or phrases that are not capitalized but appear in quotation marks are used herein as they are used for U.S. federal income tax purposes in the Code, Treasury Regulations, and administrative guidance and rulings.

In rendering the following opinions, we have examined such statutes, regulations, records, agreements, certificates and other documents as we have considered necessary or appropriate as a basis for the opinions, including, but not limited to: (1) the Registration Statement; (2) an executed copy of the Distribution Agreement, and (3) certain organizational documents of the Company and its subsidiaries (those documents referred to in clauses (1) through (3), the “Reviewed Documents”).

The opinions set forth in this letter are premised on, among other things, the written representations of the Company contained in a letter to us dated as of the date hereof (the “Management Representation Letter”). Although we have discussed the Management Representation Letter with the Company, for purposes of rendering our opinions, we have not made an independent investigation or audit of the facts set forth in the Reviewed Documents and the Management Representation Letter. We consequently have relied upon the representations and statements of the Company as described in the Reviewed Documents and the Management Representation Letter, and assumed that the information presented in such documents or otherwise furnished to us is accurate and complete in all material respects.

In this regard, we have assumed with your consent the following:

(1) that (A) all of the representations and statements as to factual matters set forth in the Reviewed Documents and the Management Representation Letter are true, correct, and complete as of the date hereof, (B) any representation or statement in the Reviewed Documents and the Management Representation Letter made as a belief or made “to the knowledge of” or similarly qualified is true, correct and complete as of the date hereof, without such qualification, (C) each agreement described in the Reviewed Documents is valid and binding in accordance with its terms, and (D) each of the obligations of the Company, and its subsidiaries, as described in the Reviewed Documents, has been or will be performed or satisfied in accordance with its terms;

(2) the genuineness of all signatures, the proper execution of all documents, the authenticity of all documents submitted to us as originals, the conformity to originals of documents submitted to us as copies, and the authenticity of the originals from which any copies were made;

(3) that any documents as to which we have reviewed only a form were or will be duly executed without material changes from the form reviewed by us; and

(4) from and after the date of this letter, the Company will comply with its representation contained in the Management Representation Letter that it will utilize all appropriate “savings provisions” (including the provisions of Sections 856(c)(6), 856(c)(7), and 856(g) of the Code, and the provision included in Section 856(c)(4) of the Code (flush language) allowing for the disposal of assets within 30 days after the close of a calendar quarter, all available deficiency dividend procedures, and the relief provisions of Treasury Regulation Section 1.857-11(c) and Section 852(e) of the Code) available to the Company under the Code in order to correct any violations of the applicable REIT qualification requirements of Sections 856 and 857 of the Code, to the full extent the remedies under such provisions are available.

Any material variation or difference in the facts from those set forth in the documents that we have reviewed and upon which we have relied (including, in particular, the Management Representation Letter) may adversely affect the conclusions stated herein.

Opinions

Based upon and subject to the assumptions and qualifications set forth herein, including, without limitation, the discussion in the next two paragraphs below, we are of the opinion that:

(1) the Company has been organized and has operated in conformity with the requirements for qualification and taxation as a REIT under the Code, beginning with its short taxable year commencing October 6, 2016, and ended December 31, 2016, and the Company’s current organization and current and proposed method of operation (as described in the Registration Statement and the Management Representation Letter) will enable it to meet the requirements for qualification and taxation as a REIT under the Code for its taxable year ending December 31, 2017, and future taxable years; and

(2) the portions of the discussions in the Registration Statement under the heading “Material U.S. Federal Income Tax Considerations” that describe applicable U.S. federal income tax law are correct in all material respects as of the date hereof.

The Company’s qualification and taxation as a REIT under the Code depends upon the ability of the Company to meet on an ongoing basis (through actual quarterly and annual operating results, distribution levels, diversity of stock ownership and otherwise) the various qualification tests imposed under the Code, and upon the Company utilizing any and all appropriate “savings provisions” (including the provisions of Sections 856(c)(6), 856(c)(7), and 856(g) of the Code and the provision included in Section 856(c)(4) of the Code (flush language) allowing for the disposal of assets within 30 days after the close of a calendar quarter, all available deficiency dividend procedures, and the relief provisions of Treasury Regulation Section 1.857-11(c) and Section 852(e) of the Code) available to the Company under the Code to correct violations of specified REIT qualification requirements of Sections 856 and 857 of the Code. Our opinions set forth above do not foreclose the possibility that the Company may have to utilize one or more of these “savings provisions” in the future, which could require the Company to pay an excise or penalty tax (which could be significant

in amount) in order to maintain its REIT qualification. We have not undertaken to review the Company’s compliance with these requirements on a continuing basis, nor will we do so in the future. Accordingly, no assurance can be given that the actual results of the Company’s operations, the sources of its income, the nature of its assets, the level of its distributions to stockholders and the diversity of its stock ownership for any given taxable year will satisfy the requirements under the Code for qualification and taxation as a REIT.

In order to qualify as a REIT, 75% of the Company’s total assets must be comprised of “real estate assets” (as that term is used for purposes of Section 856(c) of the Code) and limited other assets specified in the Code as of the close of each calendar quarter of each taxable year of the Company, and at least 75% of the Company’s gross income for any taxable year for which it seeks to qualify as a REIT must be derived from certain specified “real estate” sources, including interest on mortgage loans. The Company’s ability to comply with this requirement is entirely dependent on the Company acquiring and owning (for U.S. federal income tax purposes) on the relevant dates “real estate assets” with an aggregate value equal to, or in excess of, 75% of its “total assets” and owning throughout the relevant taxable year assets that will produce sufficient “real estate” gross income to satisfy the 75% gross income test. The value of the assets that the Company will own at the end of any future calendar quarter, cannot be known with certainty as of the date hereof. Similarly, the gross income that the Company’s assets will produce for 2017 (or future years), and the nature of that income, cannot be known with certainty as of the date hereof. The accuracy of our opinions are entirely dependent on the Company’s representations contained in the Management Representation Letter regarding the anticipated value and composition of its assets that it will own, and the nature of its income derived therefrom.

This opinion letter addresses only the specific U.S. federal income tax matters set forth above and does not address any other federal, state, local or foreign legal or tax issues.

This opinion letter has been prepared for your use in connection with the filing of the Registration Statement and speaks as of the date hereof. We assume no obligation by reason of this opinion letter or otherwise to advise you of any changes in our opinions subsequent to the effective date of the Registration Statement. Except as provided in the next paragraph, this opinion letter may not be distributed, quoted in whole or in part or otherwise reproduced in any document, or filed with any governmental agency without our express written consent.

We hereby consent to the filing of this opinion letter as Exhibit 8.1 to the Registration Statement and the reference to Hogan Lovells US LLP under the caption “Legal Matters” in the Registration Statement. In giving this consent, however, we do not admit thereby that we are an “expert” within the meaning of the Securities Act of 1933, as amended.

Very truly yours,
