Deen Dayal Jan Awas Yojna (DDJAY) is an affordable plotted housing policy introduced by the Government of Haryana under the Haryana Development and Regulation of Urban Areas Act, 1975. The policy was designed to encourage the development of planned, low-density plotted colonies in low and medium potential towns across the state, making land ownership more accessible for middle-income families.

Under this policy, the Haryana Government follows a Public-Private Partnership (PPP) model, allowing private developers to plan and construct residential colonies that meet defined infrastructure standards — including internal roads, drainage, street lighting, and green spaces — while adhering to guidelines set by the Department of Town & Country Planning, Haryana.
