The finding
Nobody knows how many openers predate the 1993 safety standard, because no federal dataset counts openers. What we can count: the Census Survey of Construction shows 16.28 million new single-family houses built with a garage from 1971 to 1992 (retrieved 2026-09-06). That is a floor for garages, not a count of openers.
What did we find?
The American Housing Survey’s 2023 Definitions file records whether a home has a garage or carport. It has no opener item, no equipment age and no replacement date. The Census Survey of Construction records garages on new houses, not openers. Any published count of pre-1993 openers was made up.
Adding up the Survey of Construction’s garage series: 16,280 thousand new single-family houses were built with a garage from 1971 to 1992. That is 71.8% of the 22,682 thousand houses completed in those 22 years.
The series starts in 1971, and the housing stock is older than that.
Public Law 101-608 § 203 sets two deadlines. Openers made from January 1, 1991 had to meet UL 325 third edition’s entrapment protection. From January 1, 1993 they also had to meet the added requirements: the second, independent sensor most people picture.
What does this page claim, and what doesn’t it?
The main claim here is that a number does not exist, so its edges matter.
An estimate would need two inputs: how often openers were fitted in each era, and how often they were replaced. No federal source we found has either. An estimate built on guessed values for both would be a guess wearing a citation.
A garage built in 1985 may never have had an opener, may have had one added later, or may be on its fourth. The figure bounds the question; it does not answer it. It does not count unsafe openers either, because openers get replaced.
The Survey of Construction series starts in 1971. Every garage built before then is outside it. Census ACS puts 26.4% of all American housing units in buildings built in 1959 or earlier.
Garages on apartment buildings, and garages added to existing houses later, are not in the series.
A pre-standard opener that is maintained and still reverses is not automatically a hazard. A newer opener with its photo-eyes bypassed is not automatically safe. We cover sensors in a separate study.
It is a paid standard. Everything we say about UL 325 is quoted from the law or the Code of Federal Regulations, never presented as if we had the standard open.
Why can’t anyone tell you the number?
Because no survey asks. “How many garage door openers predate the 1993 standard?” sounds like something a federal agency would know. It gets asked often, and answers circulate freely.
We looked for the source behind those answers and found none. So we checked what the likely datasets actually contain.
The American Housing Survey. This is the obvious place: it is the federal survey of what is in American homes, and it covers equipment in detail. We read its 2023 Definitions file directly. It records vehicle parking, and notes that “[a] garage or carport is only counted” when attached to the house.
It mentions an attached garage in its disaster-preparedness questions. It has no garage door item, no opener item, no equipment age for either and no replacement date. The survey that knows the age of your water heater does not know you have an opener.
The census and the ACS do not ask about garages at all. Table B25034 gives only the year a building was built. CPSC regulates the product and records injuries, but it publishes no count of openers in use.
The Survey of Construction records features of new houses in detail, including parking. That is why this page can say anything with numbers. But it records the parking type (one-car, two-car, three-or-more garage, carport, or none), not whether an opener was fitted.
HyreGarage analysis: this gap follows from how the surveys are scoped. Household surveys ask about equipment people pay to run and replace, such as heating, cooling, water heating and appliances, because housing-cost and energy programs need those.
An opener is cheap to run, invisible on a power bill, and attached to the building rather than the household. It falls between the surveys. So a product Congress thought dangerous enough to legislate directly has never been counted nationally.
What does the law say, and when? The record from the documents
Every entry is quoted from Public Law 101-608 or the current text of 16 CFR Part 1211, both retrieved directly. The two-deadline structure is what most accounts lose.
November 16, 1990
Public Law 101-608 is approvedSection 203 makes its own requirements “a consumer product safety rule issued by the Consumer Product Safety Commission under section 9 of the Consumer Product Safety Act.” Congress wrote the standard itself instead of asking the Commission to develop one.
January 1, 1991
First deadline: protection built into the openerThe statute: “Effective on and after January 1, 1991, each automatic residential garage door opener manufactured on or after that date for sale in the United States shall conform to the entrapment protection requirements of … UL 325, third edition, as revised May 4, 1988.”
January 1, 1991
Openers must carry a dateSubsection (d) requires the maker to “clearly identify on any container of the system and on the system the month or week and year the system was manufactured and its conformance with the requirements of subsection (b).” That is why your opener’s own label can answer the question this page asks.
July 1, 1991
Makers must warn the publicSubsection (e): manufacturers “shall, in consultation with the Consumer Product Safety Commission, notify the public of the potential for entrapment by garage doors equipped with automatic garage door openers and advise the public to test their openers for the entrapment protection feature or device required by subsection (b).”
December 21, 1992
The rule is published: 57 FR 6045516 CFR Part 1211, the Safety Standard for Automatic Residential Garage Door Operators, appears in the Federal Register. Its authority line reads “15 U.S.C. 2056 Note; 15 U.S.C. 2063 and 2065.” The “Note” is section 203 itself.
January 1, 1993
Second deadline: the added protectionOpeners must meet “any additional entrapment protection requirements” of UL 325 3rd edition taking effect by this date. 16 CFR 1211.1: “This standard applies to all residential garage door operators manufactured on or after January 1, 1993 for sale in the United States.” This is the deadline behind photo-eyes and edge sensors.
1997, 2000, 2016, 2018
The rule keeps changingPart 1211 was amended at 62 FR 46667 (Sept. 1997), 65 FR 70657 (Nov. 2000), 81 FR 20228 (Apr. 2016) and 83 FR 32569 (July 2018). The 2016 change is large: it created today’s §§ 1211.6 to 1211.13 and required software in built-in protection devices to meet UL 1998.
Why do the two dates matter?
Because each one added a layer of protection. Almost every account says “1993.” The law says 1991 and 1993, and that is the difference between one layer and two.
1991 brought protection built into the opener. The machine senses the door has hit something and reverses. Today this is 16 CFR 1211.7, “Inherent primary entrapment protection requirements”: “[a] vertically moving residential garage door operator system shall be supplied with inherent primary entrapment protection.” The door must actually touch the obstruction first.
1993 brought a second, independent device. The law required “any additional entrapment protection requirements” of UL 325 3rd edition taking effect by that date. The current rule lists what qualifies.
The first is a photoelectric sensor (photo-eyes) “that when activated results in an operator that is closing a door to reverse direction of the door, returns the door to, and stops the door at the fully open position, and the sensor prevents an operator from closing an open door.”
The others: “[a]n external edge sensor installed on the edge of the door” with the same result; an independent inherent door sensor; or “[a]ny other external or internal device that provides entrapment protection equivalent” to those.
HyreGarage analysis: the second layer matters most for the hazard people fear, because it acts before contact. An opener made in 1991 or 1992 was compliant for its date and still has only the first layer. Treating the rule as one 1993 event hides that. See how photo-eyes get bypassed or misaligned.
A third rule gets even less attention, and it lets you answer the question for your own home. Section 203(d) requires the maker to mark the unit and its box with “the month or week and year the system was manufactured and its conformance with the requirements of subsection (b).”
A UL logo or listing mark with UL 325 date marking satisfies it.
Since 1991, every opener has had to carry its own date of manufacture. Nobody can count the national total, but you can date the one over your car in about a minute. The UL 325 timeline tracks every later change to the rule.
How many garages were built before the standard?
At least 16.28 million new single-family houses with garages, 1971–1992. Census has recorded parking on new houses since 1971, and HyreGarage added it up. The first two rows are fully pre-standard. The 1990s row spans both deadlines and cannot be split, because the data is yearly.
| Era | Completions (thousands) | Share with a garage | What the era was |
|---|---|---|---|
| 1971–1979 | 10,131 | 68.3% | Carports were still common: 17% of 1971 completions had one, against 2% today. |
| 1980–1989 | 9,783 | 72.5% | The standard does not exist yet. Nothing built in this decade was required to have any entrapment protection at all. |
| 1990–1999 | 10,708 | 84.6% | The decade the rule arrives, mid-stride: January 1, 1991 and January 1, 1993 both fall inside it. |
| 2000–2009 | 12,588 | 89.1% | The garage is now standard equipment on a new American house. |
| 2010–2019 | 6,539 | 90.1% | Completions collapse after 2008; the garage share does not. |
| 2020–2025 | 5,927 | 90.7% | The highest garage share in the fifty-four years the series covers. |
| 1971–1992 (pre-standard) | 22,682 | 71.8% | 16,280 thousand garages built before the standard applied to any opener. |
| 1993–2025 (standard in force) | 32,994 | 88.7% | 29,272 thousand garages built while the standard applied. |
HyreGarage computation from the Census file parking_cust.xls, retrieved 2026-09-06. Counts are thousands of houses, as published. The garage column adds the one-car, two-car and three-or-more-car groups. Before 1992, three-or-more is not reported separately and sits inside two-car, which does not change the total. New single-family houses only.
Does the garage share differ by region? Yes, by 11 points
The share of new single-family houses built with a garage in 2025, by Census region. An 11-point spread is a reminder that a national figure describes no real place.
| Region | With a garage | With a carport | With neither |
|---|---|---|---|
| West | 94% | 1% | 6% |
| Midwest | 92% | — | 8% |
| South | 88% | 2% | 10% |
| Northeast | 83% | — | 17% |

How do you tell how old your opener is?
Read the label on the motor unit. It takes about a minute and answers the question for your house, the only version with an answer.
Look at the side or end of the powerhead, the box on the ceiling. Since January 1, 1991 the manufacture date has been required on the unit itself. Take a photo rather than reading it upside down.
The manufacture date, and any UL 325 listing mark. Section 203(d) says the UL logo or listing mark plus UL 325 date marking meets the marking rule, so seeing both together tells you something.
Two small sensors facing each other, low on the tracks on each side, usually about six inches off the floor. If a working opener has none, it likely predates the 1993 rule, or they were removed. Removal is a different and more urgent problem.
An unlabeled powerhead is either pre-1991 or has lost its label to decades of dust and heat. Either way, you cannot show it complies.
Every maker publishes a test for its own units. Since July 1, 1991 they have had to “advise the public to test their openers for the entrapment protection feature or device.” If the door does not reverse as the maker says it should, stop using the opener and have it checked.
What does the rule require today?
Part 1211 has been amended four times since 1992 and is long. These are the parts a homeowner is most likely to meet, quoted from the current text.
Who it covers
16 CFR 1211.2 defines a residential garage door operator as one that “(a) Serves a residential building of one to four single family units; (b) Is rated 600 volts or less; and (c) Is intended to be employed in ordinary locations in accordance with NFPA 70.” A five-unit building is outside it.
Built-in primary protection
§ 1211.7 says a vertically moving system “shall be supplied with inherent primary entrapment protection.” Where it tracks door position, it “shall measure or monitor the position of the door at increments not greater than 1 inch” and reverse when the door moves outside its set pattern.
The second device
The rule lists what counts: a photoelectric sensor, an external edge sensor, an independent inherent door sensor, or “[a]ny other external or internal device that provides entrapment protection equivalent.” Each must both reverse a closing door and “prevent an operator from closing an open door.”
The red handle
§ 1211.9: “[a] means to manually detach the door operator from the door shall be supplied. The gripping surface (handle) shall be colored red and shall be easily distinguishable from the rest of the operator.”
It must adjust to six feet above the floor and release with no more than 50 pounds of force when the door is blocked in the down position.
What couldn’t we verify?
UL 325 itself. It is a paid standard and we did not buy it. Every UL 325 reference here comes from the law or the federal rule describing it. We reproduce no UL test, pass mark or clause number. Any page that does, without saying where it got it, deserves a second look.
How often openers were fitted and replaced. An estimate of pre-1993 openers still in use needs both rates, and we found no federal source for either. Trade estimates exist. We did not use them: a number from a trade body’s unpublished model is not one we can defend.
Anything before 1971. The Census parking series starts there. Much of the housing stock is older: nationally, 26.4% of units are in buildings built in 1959 or earlier. None of those garages are in our 16.28 million.
Injuries. Whether older openers show up more in injury records is a real, separate question. It needs CPSC injury data, not housing data. See what federal injury data shows about garage doors.
One thing we chose not to do: turn 16.28 million garages into “X million dangerous openers.” That needs two rates nobody publishes, and the result would be quoted for years with our name on it. The number we can count is the number we publish.

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.

Replacing an opener rather than dating one?
Ask each company for the model, the drive type, and confirmation that new photo-eyes will be installed and aligned, not reused. Then the quotes describe the same job.
