89 FR 18538 (March 14, 2024): CPSC Adopts 2023 UL 325 Revision for Garage Door Operators

The federal safety standard for residential garage door operators was last updated in March 2024. The change brought the rule in line with new UL 325 requirements for smart openers controlled by apps and remote monitoring systems.

What this regulation says

89 FR 18538, published March 14, 2024, is a final rule from the Consumer Product Safety Commission. It amends 16 CFR Part 1211 to update the referenced edition of UL 325 from an earlier version to the February 2023 revision (UL 325-2023).

The core safety requirements from earlier editions remain unchanged. Every residential operator must have primary inherent entrapment protection (auto-reverse on contact) and secondary external entrapment protection (photoelectric sensor or edge sensor).

The Federal Register rule states its purpose:

"Safety Standard for Automatic Residential Garage Door Operators" (89 FR 18538, March 14, 2024), adopting the February 2023 revision of UL 325 as the updated federal reference standard.

What changed is coverage of operators controlled remotely. The 2023 revision of UL 325 added requirements for operators that can be closed via a mobile app, a remote web interface, or a timer. These operators must provide two types of warning before a remotely initiated close:

1. A visual warning: a flashing light on or near the operator must activate before the door begins moving.
2. An audible warning: a buzzer or speaker must alert anyone in or near the garage that the door is about to close.

These warnings must occur before movement begins and must be visible and audible from the door opening. They address a real hazard: a door closing remotely when someone is in the garage and unaware the door is about to move.

The 2024 Federal Register rule incorporated this addition into federal law by updating the UL 325 edition reference in 16 CFR 1211.5 and related sections.

When it applies

The updated rule applies to residential garage door operators manufactured after the rule's effective date. Operators already in service before the effective date are not retroactively required to meet the new alert requirements, but any new smart opener installed on the Front Range should meet the 2023 UL 325 requirements.

What this means for you

Smart opener safety has a new floor. If you are buying or installing a wi-fi-enabled or app-controlled opener, it must meet UL 325-2023. Look for the current UL listing mark, and confirm with the manufacturer that the listed edition is the 2023 revision.

Existing openers are not automatically non-compliant. The rule applies prospectively to new manufacturing. An opener purchased and installed before the effective date does not need to be replaced solely because of the 2024 update.

The alert requirement matters in practice. The visual and audible warnings are meaningful: they give a person in the garage time to get clear before the door closes. If you are evaluating smart openers, verify that the pre-close warning is present and operates when triggered remotely.

The two-device rule is unchanged. The 2024 update did not eliminate or modify the dual entrapment protection requirement. All new openers still need both auto-reverse and a photo-eye or edge sensor.

G Brothers installs openers that carry the current UL listing. For smart openers, we verify the pre-close alert before completing installation.
