Owners of nonexempt, occupied mobile homes, upon receipt of
notice from the City Treasurer of their liability for the monthly
parking permit fee, shall remit to the City Treasurer a cash deposit
of $25 to guarantee payment of such fees when due to the City. It
shall be the full and complete responsibility of the licensee of a
mobile home park to collect such cash deposits from each occupied,
nonexempt mobile home therein and to remit such deposits to the City
Treasurer. Upon receipt of a notice from the owner or licensee that
the nonexempt, occupied mobile home has been or is about to be removed
from the City, the City Treasurer shall apply said cash deposit to
reduce any monthly parking permit fees for which said owner is liable
and refund the balance, if any, to said owner.
