  Massive neutrino is an evidence of new physics beyond the Standard Model. One
of the well motivated new physics scenarios is a model with gauged lepton
flavor symmetry. We investigate neutrino properties in the minimal
SU$(3)_\ell\times$SU$(3)_E$ gauged lepton flavor model. In this model, three
new species of fermions are introduced to cancel gauge anomalies. These new
fermions lead to a see-saw mechanism for neutrino mass generation. We impose
the constraints from perturbative unitarity in 2-2 scattering processes, as
well as current experimental constraints, to obtain viable neutrino spectrum.
We determine the lower bound, with the SU(3)$_\ell$ gauge coupling set to 1, on
the lightest neutrino mass of $3.76\times10^{-3}\,(18.9\times10^{-3})\,$ eV for
the normal (inverted) hierarchy.
