We investigate the emergence of altermagnetism induced by the depletion of local correlations on the Lieb lattice. Specifically, we consider a scenario where local correlations at the corner sites of the Lieb lattice are depleted. To account for general non-collinear and non-coplanar magnetizations, we construct local rotations in spin space. Within dynamical mean-field theory, we find a double-diagonal strip magnetization pattern, where spins align ferromagnetically along individual diagonals but antiferromagnetically relative to adjacent diagonals.
