Alarm Registration & Renewal

The City of Huntsville Ordinance 21-984 requires the registration of security alarm systems within Huntsville city limits. Alarm systems may be registered by the alarm company at the time of installation, but residential and commercial alarm system owners should contact the Public Safety Alarms Office to confirm registration status. Unregistered alarm systems are subject to a $100 fine in addition to assessed penalties for unexcused false alarm activations.

Read a Summary of the Alarm Ordinance and follow the instructions below for residential and commercial security alarm systems.


The City of Huntsville Alarms Office has transitioned its operations to CryWolf alarms management to better serve businesses and residents and help reduce false alarms.

To contact CryWolf about your alarm registration please call, 833-811-0299 or email HuntsvilleAL@alarm-billing.com.

Once the initial registration process is completed, an alarm permit decal will be mailed to the registered party and should be placed in a highly visible location on/near the main entrance of the registered building.

The number printed on an alarm permit decal is renewable from year to year. When you renew your alarm permit, the permit number will automatically be renewed. If the decal is in good condition, a replacement is unnecessary. If the alarm permit decal is no longer posted or the condition has deteriorated, contact CryWolf to request a replacement.
