969, Dodd. Automatic garage door openers: backup batteries.

Existing law requires an automatic garage door opener that is manufactured for sale, purchased, sold, offered for sale, or installed in a residence to comply with specified safety requirements, including that the automatic garage door opener have an automatic reverse safety device.

This bill, beginning July 1, 2019, would also require an automatic garage door opener that is manufactured for sale, sold, offered for sale, or installed in a residence to have a battery backup function that is designed to operate when activated because of an electrical outage. The bill would make a violation of those provisions subject to a civil penalty of $1,000. The bill would, on and after July 1, 2019, prohibit a replacement residential garage door from being installed in a manner that connects the door to an existing garage door opener that does not meet the requirements of these provisions.
