Which states require a garage door opener battery backup?
One, as far as primary sources show. What matters more is what the law says, and what its own legislature found about the batteries.

The finding
California is the only state we could confirm. Health and Safety Code section 19892 (SB 969) bans selling or installing a home garage door opener without battery backup from July 1, 2019.
The fine is $1,000 per opener. We could not run a full fifty-state search, so this is one confirmed state, not proof there are no others (retrieved 2026-09-06).
What did we find?
Section 19892 bans making for sale, selling, offering for sale or installing a home opener without “a battery backup function that is designed to operate when activated because of an electrical outage.” The penalty under section 19891 is “one thousand dollars ($1,000) per opener”.
Under subdivision (c), a replacement door may not be connected to a non-compliant existing opener “regardless of the date of manufacture”.
DASMA reports that the California Senate’s own analysis of SB 969 estimated these batteries “typically need to be replaced ‘every three years’”. Nothing in section 19892 requires anyone to replace, test or disclose one. The duty applies at sale and installation, then stops.
LegiScan refused our requests, so we could not complete a fifty-state sweep. We do not claim no other state has such a law.
What are the limits of this answer?
A count of states needs its method attached. Here is what this one can and cannot support.
LegiScan’s multi-state bill search blocked our requests (an HTTP 403 error), so we could not sweep all fifty statute books. We can say “we found no other state”. We cannot say “California is the only state”.
Section 19892 has been in force since 2019 and could be amended. If you rely on it for business, read the current text at leginfo, not this page.
Cities and counties adopt and amend building codes on their own schedules. No state law does not mean no rule where you live.
DASMA objected to the bill because these are not life-safety devices. Every opener has a red manual-release handle, required by federal rule. Know how to use it, battery or not.
The “every three years” figure is DASMA’s report of what the California Senate’s analysis of SB 969 estimated. We quote DASMA quoting the analysis, and say so.
DASMA is the manufacturers’ association, and it opposed the bill. Its points are worth hearing and weighing with that in mind. We attribute every one of them to DASMA.
Why does California have this law when no other state does?
Because deadly wildfires in 2017 pushed it. Laws about garage door openers are rare. DASMA’s trade magazine said so in 2018: “It is extremely rare to see state or federal legislation about garage door openers.”
Its editor’s note gives the short history. Minnesota passed the first opener law on April 9, 1990. Congress, California, New York and Indiana followed that year. The 2018 California law “appears to be the first state or federal legislation to target GDOs since the flurry of legislative activity in the early 1990s.”
HyreGarage analysis: two points stand out. First, the states acted before Congress. Minnesota moved seven months before Public Law 101-608 passed in November 1990.
Second, 25 years passed between the federal rule taking effect in 1993 and the next opener law anywhere. This is not a heavily regulated product. Our UL 325 timeline tracks every federal change since.
Then came the fires. DASMA reports that Senator Bill Dodd introduced SB 969 “in response to the 2017 wildfires that left some people trapped in their garages. At least five deaths were reported to have some connection to automatic garage door openers that had no power.”
DASMA adds: “Some elderly victims were reportedly unable to use the emergency disconnect and/or lift their garage doors manually.”
When did each opener law pass?
In two bursts, 1990–1993 and 2018–2019, with 25 years of nothing in between. Each entry comes from the statute, the federal rule, or DASMA’s reporting at the time.
April 9, 1990
Minnesota acts first, before CongressDASMA’s trade magazine says Minnesota “passed the nation’s first legislation that specifically targeted residential garage door openers (requiring an external reversing mechanism such as a photo eye)”. It adds that “[a]t that time, similar legislation was adopted by the U.S. Congress and the states of California, New York, and Indiana.” The states moved first.
November 16, 1990
The federal lawPublic Law 101-608 § 203 sets two federal deadlines. From January 1, 1991, openers need built-in entrapment protection under UL 325 3rd edition, as revised May 4, 1988. From January 1, 1993, they need the added protection too.
November 16, 1990
Why states can still require moreSection 203(f) overrides only state rules on labeling, and state rules that “do not provide at least the equivalent degree of protection”. So a state is free to require more than the federal rule.
December 21, 1992
16 CFR Part 1211 is publishedThe federal safety rule appears at 57 FR 60455. It covers entrapment protection and the manual release. It says nothing about power failure, and no federal rule has since.
October 2017
The fires behind the billDASMA reports that Senator Bill Dodd introduced SB 969 “in response to the 2017 wildfires that left some people trapped in their garages. At least five deaths were reported to have some connection to automatic garage door openers that had no power.”
31 May and August 16, 2018
It passes almost unopposedThe bill cleared the California Senate 39–0 and the Assembly 64–7. DASMA says it “was the only entity that submitted formal opposition to the bill”.
September 21, 2018
Signed into lawThe Governor approved it and it was filed with the Secretary of State the same day, as Chapter 621 of the Statutes of 2018. It added Section 19892 to the Health and Safety Code, effective January 1, 2019.
July 1, 2019
The rule starts to biteFrom this date California bans making for sale, selling, offering for sale and installing a home opener without battery backup. A replacement door also may not be connected to a non-compliant existing opener.
What does the California law actually say?
It is short. Reading it takes two minutes and settles most questions. Here it is, section by section, quoted from the Health and Safety Code as enacted by SB 969.
The ban (§ 19892(a))
From July 1, 2019: “no person, corporation, or entity shall manufacture for sale in this state, sell, offer for sale at retail or wholesale, or install in this state a residential automatic garage door opener that does not have a battery backup function that is designed to operate when activated because of an electrical outage.”
It adds a performance rule: “The battery backup function shall operate in a manner so that the automatic garage door opener is operational without interruption during an electrical outage.”
What it covers (§ 19892(b))
“This section applies to all automatic garage door openers manufactured and sold for use in any residence and other residential applications of automatic garage door openers manufactured for commercial purposes.” So a commercial-grade opener fitted to a house is covered.
The part that catches people out (§ 19892(c))
“On or after July 1, 2019, no replacement residential garage door shall be installed in a manner that connects the replacement door to an existing residential automatic garage door opener that does not meet the requirements set forth in subdivision (a), regardless of the date of manufacture of the residential automatic garage door opener.”
In plain words: replace the door, and the opener must comply too, however old it is and whoever installed it.
The penalty (§ 19891(a))
“[A]ny violations of subdivision (a), (b), or (c) of Section 19890 or Section 19892 shall be subject to a civil penalty of one thousand dollars ($1,000) per opener installed, manufactured, sold, or offered for sale which is not in compliance.”
DASMA’s own coverage underlines it: “Yes, the fine is ‘$1,000 per opener.’”
Who can enforce it (§ 19891(d))
“Court proceedings may be initiated by the building department of the local agency with jurisdiction over enforcement of building standards, by affected consumers, or by the district attorney.”
And: “If an affected consumer initiates the proceeding, the civil penalties shall be payable to the consumer.” A homeowner sold a non-compliant opener can sue, not just complain.
What the law does not do
It does not make anyone replace an existing opener that stays in place. It does not require the battery to be maintained, tested or replaced. It sets no expiry, inspection or disclosure duty for the battery. The duty applies at sale and installation, then stops.
The batteries last about three years, and the law never asks anyone to replace them
DASMA opposed SB 969 with two arguments. One is a trade group defending its members. The other has turned out to be the lasting point.
The first was about the category: “garage door openers with backup batteries are not designed to serve as life safety devices.” That is partly a manufacturer’s liability position, so weigh it that way. It is also true. No federal or UL rule says what a backup battery must do in a fire.
The second is the one that matters: “battery backup systems require regular maintenance” and “must be regularly tested and periodically replaced.” DASMA also reports that the California Senate’s own analysis estimated these batteries typically need to be replaced “every three years.”
HyreGarage analysis: set that next to the law and a gap opens. Section 19892 covers making, selling, offering and installing. It says nothing about maintenance, testing, replacement, labeling battery age, or disclosure when a home is sold. The duty ends once a compliant opener is installed.
Follow it forward. The law took effect on July 1, 2019. On the legislature’s three-year estimate, openers installed that first year hit their first battery replacement around 2022, the second around 2025 and the third around 2028. Nothing in the law makes any of those happen.
So the number of California homes with a legally required backup battery that no longer holds a charge grows every year. You cannot see it: a dead battery looks like a working one until the power fails. Our study of who gets shut in when the power goes out covers the outage side.
To be clear: we are not claiming a measured failure rate. Nobody publishes one and we did not measure one. The three-year figure is a second-hand estimate from an analysis we did not read.
Our point comes from the law’s text alone: a rule applied at sale, on a part that wears out, fades unless something renews it.
How can you check what applies where you live?
Use your state’s own legislature website. We could not search fifty statute books, but you can search one in about fifteen minutes and get an answer you can cite.
Every state publishes its code and bill history. Search the code for “garage door opener” and “automatic garage door”. California’s rule sits in the Health and Safety Code at §§ 19890–19892. Yours, if it exists, will be in a building, housing or consumer protection title.
A bill that died leaves no trace in the code, but it shows what your state has considered. It also tells you whether the question is still live.
This decides what applies to your permit. Ask which code edition is in force and whether any local change covers garage door openers. Get the answer in writing.
HyreGarage analysis: most “battery backup laws by state” pages we found were published by sellers of openers. None we saw cited a statute. A page that names a rule without naming its section cannot be checked.
Subdivision (c) makes the door job and the opener job one job. Raise it before the quote is written, and get the compliance position in writing. Our garage door opener guide explains the choices.
What do the legal terms mean?
- Battery backup function
- The law sets no technical standard. Section 19892(a) says only that it must be “designed to operate when activated because of an electrical outage” and keep the opener “operational without interruption during an electrical outage.” It sets no runtime, cycle count, battery type or service life.
- Residential automatic garage door opener
- Under § 19892(b), “all automatic garage door openers manufactured and sold for use in any residence and other residential applications of automatic garage door openers manufactured for commercial purposes”. A commercial-grade opener on a house is covered.
- Civil penalty
- $1,000 per non-compliant opener under § 19891(a). This is separate from the $500 per opener that § 19891(b) sets for certain § 19890 violations, and from the $500 for a seller’s breach of the Civil Code § 1102.6 disclosure rule.
- Affected consumer
- Under § 19891(d), one of three parties who can bring a case, with the local building department and the district attorney. Only the consumer keeps the penalty: “If an affected consumer initiates the proceeding, the civil penalties shall be payable to the consumer.”
- Manual release
- The red handle, required by 16 CFR 1211.9. It must be red and “easily distinguishable from the rest of the operator”, adjustable to six feet above the floor, and free the door with at most 50 pounds of force when blocked in the down position. It works in a power cut, battery or not.
- Preemption
- Where federal law overrides state law. Public Law 101-608 § 203(f) overrides only state labeling rules and rules that “do not provide at least the equivalent degree of protection”. A state may require more than the federal rule, never less, and may not add its own label.
What couldn’t we verify?
A fifty-state sweep. This is the big gap, and it limits the headline. LegiScan’s multi-state search blocked our requests (an HTTP 403 error) on the retrieval date.
Reading fifty statute books one by one was beyond this page. We report one confirmed state and a search that found no others. We do not claim none exist.
The California Senate’s bill analysis. The “every three years” estimate is central here, and we have it second-hand: DASMA reporting what the analysis said. We say so every time. Anyone building on it should pull the committee analysis from the bill history at leginfo.
Enforcement. We found no record of how often § 19892 has been enforced, by whom, or with what result. California does not appear to publish one centrally. A $1,000-per-opener penalty with a private right to sue makes that history worth knowing, but we cannot report it.
Field checks of battery condition. The three-year point is structural, drawn from the law’s text and a reported estimate. Nobody has surveyed California garages to count how many required batteries still work. We did not either.

Primary-source research, data analysis and fact checking
We are not a garage door company. We read the agency file, the code record, the standards document or the public register ourselves, compute the figure from it, and publish it with the source and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. Our own company records cover ten states; nothing national is ever derived from them.
- 10
- states our own company records cover — and the limit of any claim made from them
- 3,901
- garage door companies in the store
- 457
- license records verified against a state board
- 0
- national claims made from a ten-state store
How this desk works
- Primary sources only. Injury counts come from CPSC. Housing counts come from the Census file, not from a summary of it. Code history comes from the building commission that adopted the code. We do not cite an article that cites a source; we retrieve the source and do the arithmetic ourselves.
- Every figure carries its retrieval date. Registers change, datasets are revised and codes are amended. A number without the date it was read cannot be checked, so every study states one.
- Fact, calculation and analysis are labeled apart. A quote is a quote, a HyreGarage computation says so, and an interpretation says “HyreGarage analysis”. Presenting our reading of a dataset as something the agency stated would be the easiest way to lose the only thing this desk is for.
- Limitations go above the fold. If a figure is an upper bound, a bracket, or an association rather than a cause, that is said before the figure is quoted rather than in a footnote underneath it.
- No DIY instructions for spring, cable or track work. Those components hold enough stored energy to cause serious injury, and CPSC records the consequences. We describe what has failed and what a competent repair involves; we do not tell you how to do it.
