You're not going a lot of details about exactly what the use case you
have in mind; are you talking about a non-root user creating a file
system which then gets mounted somwhere?  In practice you still need
root to do the mount, or at the very least to set up the /etc/fstab to
allow a non-root user to mount a file system at a particular mount
point.

If it's the latter which you are envisioning, then the root_owner
extended option to mke2fs(8) may be what you're looking for.

If it isn't please go into a much greater detail about what exactly it
is you are trying to do, and why.
