City of Miami Ordinance 3-23 (c) states:


An alarm system registered with the Alarm Ordinance Unit must have its permit renewed by the end of the permit year. After successfully renewing your alarm system, a new decal will be issued to you by the Alarm Ordinance Unit.

In late August, all registered alarm system owners will receive an invoice for the next permit year renewal. The invoice is sent through the US Mail.


If the renewal invoice is paid by September 30th, your alarm system registration will stay valid. You will receive a new decal shortly after payment is submitted. If you pay in person in the Alarm Ordinance Unit office, you will receive your decal at that time.

If this invoice is not paid by September 30th, then on October 1st your alarm system registration goes into an expired state. The following are possibilities you could be facing because of this:

• Assessed a late fee of $26.50 by the city’s Finance Department, which becomes part of the renewal fee and must be paid in full before your alarm system is re-activated
• A false alarm activation will result in an expired fine incident for which you will receive a $240.00 invoice. This must be paid in full before your alarm system is re-activated

The cost of your renewal depends on the following:

• No activations in the prior permit year results in a renewal fee of $30.00 (26.50 renewal fee, $3.50 administrative fee)
• 1 or more activations in the prior permit year results in a renewal fee of $82.50 ($79.00 renewal fee, $3.50 administrative fee)

Additionally, non-payment of a renewal invoice after September 30th will result in a $26.50 late fee being added to the invoice.

The initial $30.00 renewal fee plus $26.50 late fee equals a new invoice amount of $56.50
The initial $82.50 renewal fee plus $26.50 late fee equals a new invoice amount of $109.00
