If getting back to schroot mode is not a problem for you, there is the option to follow these instructions[1] I wrapped up a couple of years ago. They should still apply, modulo the fact that it is necessary to also pass --chroot-mode=schroot to the sbuild command, or adjust the sbuildrc to change the default mode.

I would expect any method involving bind-mount to require running the pre-build commands as root, and any method involving mknod to require work with capabilities(7), user_namespaces(7) and setcap(8), but implementation details are evading me so far. In hope this helps, -- .''`.
