We show that if $0<t<s\leq n-1$, $\Omega\subseteq \mathbb{R}^{n}$ with lower$s$-content regular complement, and $z\in \Omega$, there is a chord-arc domain$\Omega_{z}\subseteq \Omega $ with center $z$ so that$\mathscr{H}^{t}_{\infty}(\partial\Omega_{z}\cap \partial\Omega)\gtrsim_{t}\textrm{dist}(z,\Omega^{c})^{t}$. This was originally shown by Koskela, Nandi,and Nicolau with John domains in place of chord-arc domains when $n=2$, $s=1$,and $\Omega$ is a simply connected planar domain.  Domains satisfying the conclusion of this result support $(p,\beta)$-Hardyinequalities for $\beta<p-n+t$ by a result of Koskela and Lehrb\"{a}ck;Lehrb\"{a}ck also showed that $s$-content regularity of the complement for some$s>n-p+\beta$ was necessary. Thus, the combination of these results gives acharacterization of which domains support pointwise $(p,\beta)$-Hardyinequalities for $\beta<p-1$ in terms of lower content regularity.
