Alarm Permit Information

The City of Lake Oswego encourages alarm users and alarm businesses to assume increased responsibility for maintaining the mechanical reliability and the proper use of alarm systems to prevent unnecessary police emergency response to false alarms, thereby contributing to the protection of the emergency response capability of the City while ensuring the public is protected from unreasonable alarm noise. 

The alarm user may obtain an alarm permit annually for each alarm system they have. The permit will be valid for a one-year period immediately following the issuance of the permit. There are exceptions and costs associated with alarm permits. Please refer to Lake Oswego City Code Article 20.08 for more details about use, fees, and enforcement.

As of July 1, 2026, the City of Lake Oswego has partnered with Alarm Program Systems (APS) to administer the alarm ordinance. Access Lake Oswego’s official alarm program website to obtain information about the alarm program.
