Most efficient is to query disk quotas. Disk quotas must be enabled on the system that owns the data (NFS server if NFS is used); it's not necessary to use limits.
Less efficient: run a find -ls on the folders and post-process the output (with awk or perl or shell-builtins).

quotaoff
QUOTAON(8) BSD System Manager's Manual QUOTAON(8)
NAME
quotaon, quotaoff -- turn filesystem quotas on and off
SYNOPSIS
quotaon [-g] [-u] [-v] filesystem ...
quotaon [-g] [-u] [-v] -a
quotaoff [-g] [-u] [-v] filesystem ...
quotaoff [-g] [-u] [-v] -a
DESCRIPTION
quotaon announces to the system that disk quotas should be enabled on one or more filesystems. quotaoff announces to the system that the
specified filesystems should have any disk quotas turned off. The filesystems specified must have entries in /etc/fstab and be mounted.
quotaon expects each filesystem to have quota files named quota.user and quota.group which are located at the root of the associated file
system. These defaults may be overridden in /etc/fstab. By default both user and group quotas are enabled.
Available options:
-a If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable all the filesystems indicated in
/etc/fstab to be read-write with disk quotas. By default only the types of quotas listed in /etc/fstab are enabled.
-g Only group quotas listed in /etc/fstab should be enabled/disabled.
-u Only user quotas listed in /etc/fstab should be enabled/disabled.
-v Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off.
Specifying both -g and -u is equivalent to the default.
FILES
quota.user at the filesystem root with user quotas
quota.group at the filesystem root with group quotas
/etc/fstab filesystem table
SEE ALSO
quota(1), libquota(3), fstab(5), edquota(8), quotacheck(8), repquota(8)
HISTORY
The quotaon command appeared in 4.2BSD.
