We theoretically study the stability of lattice supersolid states\nin the extended Bose-Hubbard model with bounded spatial disorder.\nWe construct a disorder mean-field theory and compare with quantum\nMonte Carlo calculations. The supersolid survives weak disorder on\nthe simple cubic lattice. We also find that increasing disorder strength\ncan transform a lattice solid into a supersolid as it tends to percolate\nthrough the disorder landscape.
