We explore the extent to which well-posedness results for the Poisson problem with a Dirichlet boundary condition hold in the setting of weighted Sobolev spaces in rough settings. The latter includes both the case of (strongly and weakly) Lipschitz domains in an Euclidean ambient, as well as compact Lipschitz manifolds with boundary.
