Since July 1, 2019, California law (Health and Safety Code section 19892) says residential garage door openers sold or installed in the state need a battery backup that keeps the opener working during a power outage. A replacement garage door also cannot be connected to an older residential opener that lacks one. A civil penalty applies to each noncompliant opener.
1What the law says
Section 19892 of the California Health and Safety Code deals with the battery backup on residential automatic garage door openers. On or after July 1, 2019, nobody may manufacture for sale, sell, offer for sale or install a residential opener in California unless it has a battery backup.
The backup has a clear job: it must keep the opener working without interruption during an electrical outage. The same section covers openers made for commercial use when they are used in a home, so a heavy-duty opener does not escape the rule just because it was designed for a shop.
2What it covers, case by case
| Your situation | What the law says | What it means for you |
|---|---|---|
| Buying a new opener for a home | A residential opener sold, offered for sale or installed in California needs a battery backup | Pick a model that has the battery backup, and ask the installer to confirm it |
| Installing a replacement garage door | A replacement residential door cannot be connected to an existing residential opener that does not meet the rule, whatever year the opener was made | If your opener has no battery backup, plan to replace the opener with the door |
| Using a commercial-style opener at home | Subdivision (b) applies the rule to residential uses of openers made for commercial use | The same battery backup requirement applies |
| Keeping your current door and opener | The section regulates making, selling, installing and connecting replacement doors | Ask your installer if you are unsure how it applies to a repair |

3What the backup has to do
The text asks for an opener that stays operational through an outage. It does not tell you how big the battery is or how many cycles it must run, so the runtime depends on the model. Check the manual or the manufacturer's model page for what your opener's backup is designed to do, and replace the battery on the schedule the manual gives.
Look for a battery compartment on the opener head or a backup battery listed in the owner's manual. If you cannot find either, ask a technician to check the model number before you order a new door.
4Why a new door brings up the opener
The replacement-door rule is the one that surprises most homeowners. A door company cannot hook a new door to an older residential opener that lacks the backup, so a door quote can turn into a door and opener quote. That is not an upsell. It is how the law is written.
If you are weighing doors at the same time, see insulated vs non-insulated doors and our new garage door page, and budget for the opener on the same visit.
5Questions to ask before you buy an opener
- Does this model include a battery backup, and is it installed?
- Is the price for the opener installed, with the backup, or is the backup extra?
- Is the opener belt-drive, chain-drive or wall-mount, and does it suit the door's weight?
- What does the manual say about testing the backup and replacing its battery?
- Will the safety sensors and the auto-reverse be tested before the technician leaves?
Our typical price for a belt-drive opener installed with battery backup is $550 to $900, and the final price is confirmed after we see the door. Compare quotes line by line. See opener installation.

Questions people ask
Do I have to replace my old opener?
The section regulates making, selling, installing and connecting replacement doors. It does not say that owners must replace a working opener, but replacing the door triggers the rule for the opener that the new door connects to.
Can I buy a non-battery backup opener out of state and install it in California?
The section prohibits selling, offering for sale and installing residential openers without a battery backup in California on or after July 1, 2019, so a non-compliant opener should not be installed in a California home.
Is there a penalty for installing a noncompliant opener?
Yes. Section 19891 sets a civil penalty for each noncompliant opener that is installed, manufactured, sold or offered for sale.
Where can I read the law itself?
