Ladies and Gentlemen:

We have acted as counsel to Global Self Storage, Inc., a Maryland corporation (the "Company"), in connection with the Company's registration statement on Form S-8, as filed with the Securities and Exchange Commission (the "Commission") on June 29, 2026 (the "Registration Statement") for registration under the Securities Act of 1933, as amended (the "Securities Act"), of up to 1,000,000 shares (the "Shares") of the Company's common stock, par value $0.01 per share, which may be issued from time to time pursuant to the Global Self Storage, Inc. Amended and Restated 2017 Equity Incentive Plan (the "Plan").

In rendering the opinion expressed below, we have examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of such corporate records, documents, certificates and other instruments as in our judgment are necessary or appropriate.

Based on the foregoing, and such other examination of law and fact as we have deemed necessary, we are of the opinion that the Shares have been duly and validly authorized and, when issued in the manner and for compensation contemplated by the Registration Statement and the Plan, will be validly issued, fully paid and nonassessable.

The opinion stated herein is limited to the Maryland General Corporation Law as currently in effect.

We express no opinion as to other laws, statutes, ordinances, rules or regulations, and we assume no responsibility for the applicability or effect of such laws, statutes, ordinances, rules or regulations of any other jurisdiction. In addition, we have assumed that the resolutions of the Company's board of directors or its compensation committee authorizing the Company to issue and deliver the Shares pursuant to the Plan and the applicable award agreements will be in full force and effect at all times at which such Shares are issued and delivered by the Company, and that the Company will take no action inconsistent with such resolutions.

This letter has been prepared for your use in connection with the Registration Statement and is based upon the law as in effect and the facts known to us on the date hereof. We have not undertaken to advise you of any subsequent changes in the law or of any facts that hereafter may come to our attention. <br>

We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.

Very truly yours,

/s/ Clifford Chance US LLP***
