    This can be (mostly) made to work.

    Mount the filesystem on the host machine with quotas enabled,
    pointing to a file reachable by the jail. Example /etc/fstabs:

    /dev/da0s1d /JAIL_NAME/home ufs rw,nosuid,nodev,userquota=/JAIL_NAME/usr/quotas/JAIL_NAME.home 2 2

    In the jail, use

    /dev/da0s1d /home ufs rw,nosuid,nodev,userquota=/usr/quotas/JAIL_NAME.home,noauto 2 2

    Remember that you only have a single namespace (numberspace?) for
    UIDs so do not re-use them in other jails.
