with sbuild you can use --extra-package=package.deb or
--extra-package=/path/to/debs and then sbuild will use those debs or all debs
in the directory you specify, respectively, to satisfy dependencies and you
don't need to manage an apt repository yourself.

This depends on the chroot backend you are using. The default backend is
schroot and you probably want a solution for that one and not for the
autopkgtest or unshare backend. With schroot you would add additional mount
points by editing /etc/schroot/sbuild/fstab

You can either use this sbuild option:
--extra-repository="deb http://deb.debian.org/debian experimental main"
or you can use the option
--chroot-setup-commands="echo 'deb ...' >> /etc/apt/sources.list"
which runs arbitrary shell scripts inside your chroot.
All of the above is documented in the sbuild man page but there is lots of
stuff in there so I can understand why it's hard to find things without reading
the whole thing first. Anyways, if you see ways how to improve the man page,
I'd like to hear about them. Other than that there is
https://wiki.debian.org/sbuild which collects common recipes of how to use
sbuild in different scenarios, so feel free to add things you find useful to
it.
Thanks!
