The isovalently doped high-$T_{\text{c}}$ superconductorBaFe$_2$(As$_{1-x}$P$_x$)$_2$ is characterized by a rich temperature-dopingphase diagram, which includes structural, antiferromagnetic, andsuperconducting phase transitions. In this work, we use photomodulatedreflectance at 1.5 eV to detect the onset of linear birefringence in the normalstate, and by inference, the breaking of four-fold rotational (C$_4$) symmetry.We find that C$_4$ breaking takes place in the normal state over a range of $x$that spans the optimal P concentration, unlike the line oforthorhombic-tetragonal and magnetic phase transitions, which terminates at, orjust below, the optimal value of $x$.
