    <dei:AmendmentDescription contextRef="c-1" id="f-37">This Amendment No. 1 on Form 10-K/A (&#x201c;Amendment&#x201d;) amends the Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (&#x201c;Original 10-K Filing&#x201d;) of Elme Communities (&#x201c;Elme&#x201d; or the &#x201c;Company&#x201d;) filed with the Securities and Exchange Commission (&#x201c;SEC&#x201d;) on February 27, 2026. The Original 10-K Filing omitted certain information required by Part III of Form 10-K (&#x201c;Part III&#x201d;) in reliance on General Instruction G(3) to Form 10-K (&#x201c;Instruction&#x201d;), under which the information required by Part III (Items 10, 11, 12, 13 and 14) could be incorporated by reference into the Original 10-K Filing from our definitive proxy statement for an annual meeting of shareholders (&#x201c;Proxy Statement&#x201d;) if the Proxy Statement were filed with the SEC not later than 120 days after the end of the fiscal year covered by the Original 10-K Filing or as an amendment to the Form 10-K if such amendment is filed no later than the end of the 120-day period. This Amendment is being filed as permitted by the Instruction to provide the information required by Part III. As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the &#x201c;Exchange Act&#x201d;), Part IV of the Original 10-K Filing is being amended solely to add as exhibits certain new certifications in accordance with Rule 13a-14(a) under the Exchange Act. Because no financial statements have been included in this Amendment and this Amendment 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.Except as described above, this Amendment does not amend or otherwise update any information in the Original 10-K Filing, and the Original 10-K Filing, as amended by this Amendment, continues to speak as of the date of the Original 10-K Filing, other than as expressly indicated in this Amendment. Accordingly, this Amendment should be read in conjunction with the Original 10-K Filing.</dei:AmendmentDescription>
