The boundary regularity for the normalized $p$-parabolic equation $u_t =\frac{ 1}{ p}|Du|^{ 2-p}\Delta_pu$ is studied. Perron's method is used to construct solutions in arbitrary domains. We classify the regular boundary points in terms of barrier functions, and prove an Exterior Sphere result. A fundamental solution is identified. A Petrovsky criterion is established, and we examine the convergence of solutions as $p \to \infty$.
