  We present an $A_4$ flavor extended $\rm B-L$ model for realization of eV
scale sterile neutrinos, motivated by the recent experimental hints from both
particle physics and cosmology. The framework considered here is a gauged $\rm
B-L$ extension of standard model without the introduction of right-handed
neutrinos, where the gauge triangle anomalies are canceled with the inclusion
of three exotic neutral fermions $N_{i}$ ($i=1,2,3$) with $\rm B-L$ charges
$-4,-4$ and $5$. The usual Dirac Yukawa couplings between the SM neutrinos and
the exotic fermions are absent and thus, the model allows natural realization
of eV scale sterile-like neutrino and its mixing with standard model neutrinos
by invoking $\rm A_4$ flavor symmetry. We demonstrate how the exact
tri-bimaximal mixing pattern is perturbed due to active-sterile mixing by
analyzing $1+3$ case in detail. We also show the implication of eV scale
sterile-like neutrino on various observables in neutrino oscillation
experiments and the effective mass in neutrinoless double beta decay. Another
interesting feature of the model is that one of three exotic fermions is
required to explain eV scale phenomena, while other two fermions form stable
dark matter candidates and their total relic density satisfy the observed
$3\sigma$ limit of Planck data. We constrain the gauge parameters associated
with $U(1)$ gauge extension, using relic density and collider bounds.
