KEY TAKEAWAYS
- Since July 1, 2019, every automatic garage door opener sold or installed in a California home must have a battery backup (Senate Bill 969).
- Replacing your garage door? The new door cannot be connected to an old opener that has no battery backup.
- Penalty: the law sets a $1,000 civil penalty per violation for sellers and installers.
- Why it matters here: power shutoffs during high fire risk can leave you without power. A charged backup keeps the door working, usually for about 20 cycles or up to 24 hours depending on the model.
If you are buying or installing a garage door opener in California, it must have a battery backup. The rule comes from Senate Bill 969, and it has applied since July 1, 2019. Here is what it means for your home, in plain English.
What the law says
Short answer: new openers in California homes must keep working during a power outage. SB 969 says an automatic garage door opener that is made for sale, sold, offered for sale, or installed in a home must have a battery backup that works when the power goes out.
The law also covers new garage doors. A replacement door cannot be installed in a way that connects it to an existing opener that does not meet the battery backup rule. A violation carries a civil penalty of $1,000.
Who it affects
- Buying a new opener: it must include a battery backup. Most current models from brands like LiftMaster and Chamberlain have one built in or available.
- Replacing your garage door: if your current opener has no battery backup, plan to replace the opener too. See garage door replacement.
- Keeping your current door and opener: the law is about openers that are sold or installed and doors connected to them. It does not tell you to remove an opener that was already in place. Still, a backup is a smart safety upgrade.
Why California passed it
The law followed the 2017 Northern California wildfires. During those fires, some people lost power and could not open their garage doors to escape. A battery backup keeps the door working so you can get your car out.
How a battery backup works
The battery sits inside or next to the opener and charges while the power is on. When the power goes out, the opener switches to the battery.
- How long it lasts: many LiftMaster and Chamberlain backups are rated for about 20 open-and-close cycles or up to 24 hours on standby, depending on the model.
- Recharging: after the power comes back, the battery usually recharges within about a day.
- Replacing the battery: plan on a new battery every 1 to 3 years. Many openers beep or show a light when the battery is weak.
Power shutoffs in Southern California
Short answer: during high fire risk, the utility may turn your power off on purpose. Southern California Edison runs Public Safety Power Shutoffs in high fire risk areas during dangerous weather, often when Santa Ana winds blow. SCE has said shutoffs could happen more often and last longer in 2026.
Two simple steps help:
- Keep the backup battery healthy. Replace it when the opener warns you.
- Learn the manual release. It is the red cord on the opener rail. Only use it with the door fully closed, because a door with a broken spring can drop fast.
How to check your opener
- Look for a battery indicator light or a battery compartment on the opener.
- Find the model number on the label and search the brand’s website.
- Unplug the opener and press the wall button. If the door runs, you have a working backup. If it does not, call us.
While you are at it, test your safety sensors. Federal rules under UL 325 have required a safety reversing system, usually photo-eye sensors near the floor, on openers made since 1993.
Choosing a new opener
- Quiet: a belt-drive opener for garages under bedrooms.
- Budget and strength: a chain-drive opener for detached garages.
- Clear ceiling: a wall-mount opener.
- Phone control: a smart opener.
