  The 5$d$ based SrIrO$_3$ represents prototype example of nonmagnetic
correlated metal which mainly originates from a combined effect of spin-orbit
coupling, lattice dimensionality and crystal structure. Therefore, tuning of
these parameters results in diverse physical properties in this material. Here,
we study the structural, magnetic and electrical transport behavior in
epitaxial SrIrO$_3$ film ($\sim$ 40 nm) grown on SrTiO$_3$ substrate. Opposed
to bulk material, the SrIrO$_3$ film exhibits a ferromagnetic ordering at low
temperature below $\sim$ 20 K. The electrical transport data indicate an
insulating behavior where the nature of charge transport follows Mott's
variable-range-hopping model. A positive magnetoresistance is recorded at 2 K
which has correlation with magnetic moment. We further observe a nonlinear Hall
effect at low temperature ($<$ 20 K) which arises due to an anomalous component
of Hall effect. An anisotropic behavior of both magnetoresistance and Hall
effect has been evidenced at low temperature which coupled with anomalous Hall
effect indicate the development of ferromagnetic ordering. We believe that an
enhanced (local) structural distortion caused by lattice strain at low
temperatures induces ferromagnetic ordering, thus showing structural
instability plays vital role to tune the physical properties in SrIrO$_3$.
