The domain growth processes originaated from noise-induced phase transitions are analyzed, both for conserved and non-conserved dynamics. The existence of a scaling regime is established in the two cases, and the corresponding growth laws are determined. Additionally, we point out a generic anomalous behavior of the pair correlation function at short distances in the presence of noise sources, and identify its origin analytically.
