Amendment Description	This Amendment No. 1 to the Annual Report on Form 10-K (this "Amendment No. 1") of Broad Street Realty, Inc. (the "Company," "we," "us," and "our,") amends the Company's Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the Securities and Exchange Commission (the "SEC") on April 15, 2022 (the "Original Form 10-K"). This Amendment No. 1 is being filed for the sole purpose of including the information required by Part III of Form 10-K. In accordance with Rules 12b-15 and 13a-14 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we have also amended Part IV, Item 15 to include currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 from our principal executive officer and principal financial officer. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Similarly, because no financial statements have been included in this Amendment No. 1, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted.Except as described above, this Amendment No. 1 does not amend any other information set forth in the Original Form 10-K, and we have not updated disclosures included therein to reflect any subsequent events. This Amendment No. 1 should be read in conjunction with the Original Form 10-K and with our other filings made with the SEC subsequent to the filing of the Original Form 10-K.
