We present a method of construction of exact localized many-body eigenstatesof the Hubbard model in decorated lattices, both for $U=0$ and$U\rightarrow\infty$. These states are localized in what concerns both hole andparticle movement. The starting point of the method is the construction of aplaquette or a set of plaquettes with a higher symmetry than that of the wholelattice. Using a simple set of rules, the tight-binding localized state in sucha plaquette can be divided, folded and unfolded to new plaquette geometries.This set of rules is also valid for the construction of a localized state forone hole in the $U\rightarrow\infty$ limit of the same plaquette, assuming aspin configuration which is a uniform linear combination of all possiblepermutations of the set of spins in the plaquette.
