The Reservoir District Tax Exemption Temporary Amendment Act of 2026 aims to amend Chapter 46 of Title 47 of the District of Columbia Official Code to designate certain properties as affordable housing, which will be subject to Fair Market Rents as determined by the U.S. Department of Housing and Urban Development (HUD). The bill includes a reorganization of sections within the code, specifically redesignating section 47-4683 to 47-4684 and the second section 47-4682 to 47-4683.

Additionally, the bill amends section 47-4683(b)(2) to require that one-third of the operating rental housing units in the designated property be set aside as affordable housing. These units will be available to households that qualify for the 80 Percent Income Limit Category based on the Multifamily Tax Subsidy Project Income Limits for the Washington-Arlington-Alexandria HUD Metro Fair Market Rent Area, as reported annually by HUD. The act will take effect upon approval by the Mayor and will expire 225 days after its enactment.
