Research study
Who licenses garage door installers? Almost no one
A garage door is the heaviest moving thing in most homes. Here is what a state actually asks of the person who installs one.

The finding
Few states license garage door installation as its own trade. In our 457 verified license records, California (CSLB class D28) and Nevada (C-3D, Overhead Doors) name the trade.
Arizona files all 16 of our records under CR-5, a class that names no trade. Texas, per its licensing agency’s program list, licenses elevator contractors but not garage doors. This covers three states, not a national count.
What did we find?
We audited our own license records. HyreGarage holds 457 verified contractor license records for garage door companies. They cover three of the ten states in our company list. The classification field on each record tells a clear story.
California has a class that names the trade: CSLB D28, Doors, Gates and Activating Devices. 268 of our 315 California records hold it on its own. Nevada has one too, C-3D, Overhead Doors, on 121 of our 126 Nevada records.
Arizona does not. All 16 of our Arizona records sit under CR-5, “As Restricted by the Registrar”, a class whose title names no trade. The work shows up only in a typed-in note on the record, written six different ways across those 16 records.
Some states license no construction at all. The Texas Department of Licensing and Regulation program list covers electricians, air conditioning contractors and elevator contractors. It has no program for garage doors. Washington registers contractors instead of licensing them.
The limit of this finding: license records for three states. It is not a fifty-state survey and not a national count.
What this page can and cannot claim
The main evidence here is our own data, so the scope rules are stricter, not looser.
Those three are California, Nevada and Arizona. Every classification finding here is limited to them. There is no national claim on this page, and none should be read into it.
We hold no license records for Texas, Florida, Colorado, Georgia, North Carolina, Washington or Tennessee. For Texas and Washington we checked the state directly. For the other five we did not, and the table says so.
Where we could not reach a board, we record the position as not established. Florida’s DBPR and Georgia’s Secretary of State both returned HTTP 403 (access blocked) to us. A website that will not load is not evidence of anything.
Plenty of good garage door companies work in states that license nothing. A license number does not tell you if the last spring was wound correctly. This page is about what the state asks, not who is good.
Our data records what can be verified about companies. It is not a ranking, and nothing here should be read as one.
Classes are added and retired, and registration rules move. Everything here carries a retrieval date. Check it with the board before you rely on it for business.
Why is this harder to answer than it looks?
Because "is the work licensed?" and "does the state name the trade?" are two separate questions. Ask who licenses garage door installers and you tend to hear one of two confident answers. Both are wrong.
The first: of course they are licensed, because contractors are licensed. The second: nobody licenses them at all.
The truth is more specific. Whether a state licenses this work, and whether it treats it as its own trade, are two questions with different answers.
A state can require a license for the job without having any class that describes it. Then the work is done under a general class, and the state cannot tell who does it.
You only see this by reading the classification field on many real license records. Our data lets us do that. We hold 457 verified license records for garage door companies, from three state boards. Their classes answer the second question directly.
HyreGarage analysis: this matters to you as a homeowner. If a state has a class for the trade, you can search its register for it. Then the license on your quote says something about this exact work.
If it does not, a license number only says the company may build things in general. A general building contractor has not, by that fact, ever wound a torsion spring (the tightly wound spring above the door that lifts its weight). For what a spring job involves, see garage door spring repair.
What do the license records actually say?
Counted from HyreGarage’s license data. Each record is traced to the board that issued it. The classification column shows the field exactly as the board records it.
| State | Authority | Records held | Classification | Names the trade? |
|---|---|---|---|---|
| California | California Contractors State License Board (CSLB) | 315 | D28 — Doors, Gates and Activating Devices | Yes |
| Nevada | Nevada State Contractors Board (NSCB) | 126 | C-3D — Overhead Doors | Yes |
| Arizona | Arizona Registrar of Contractors (ROC) | 16 | CR-5 — “As Restricted by the Registrar” | No |
HyreGarage license data, counted 2026-09-06, from our list of 3,901 garage door companies across 10 verified states and 2,709 cities. We hold license records for three of the ten states. No records for the other seven reflects our research so far, not a finding about them.
Arizona writes the same trade six different ways
All 16 of our Arizona records carry the same class: CR-5, “As Restricted by the Registrar”. The trade appears only in the restriction note. This is every different version of it in our records.
| Restriction text, as recorded | Records |
|---|---|
| GARAGE DOORS AND OPENERS | 7 |
| GARAGE DOORS & OPENERS | 3 |
| GARAGE DOOR AND OPENERS | 2 |
| GARAGE DOORS | 2 |
| GARAGE DOORS & AUTOMATIC GATES | 1 |
| GARAGE DOORS AND OPENERS ONLY | 1 |
HyreGarage audit of Arizona Registrar of Contractors records, 2026-09-06. 16 records, six different texts for really the same trade. One, “GARAGE DOORS & AUTOMATIC GATES”, is truly broader. The other five are the same work spelled differently. Sixteen records is small: it shows how the field works, not the size of Arizona’s register.
Why is a typed-in note not a real classification?
Because you cannot search or count it reliably. The Arizona table can look like simple clerical mess. It is more than that, and it has a cost.
A classification uses a fixed list of names. When California records D28, it means the same thing on every record. The board can list every holder, you can search for it, and a researcher can count it. That is what makes a category a category.
A typed-in restriction has none of that. “GARAGE DOORS AND OPENERS” and “GARAGE DOORS & OPENERS” are the same scope but different text. A search for one misses the other. Any count is a count of spellings.
The real differences sit in the same field as the typing differences. “GARAGE DOORS” leaves out openers. “GARAGE DOORS & AUTOMATIC GATES” adds gates. “GARAGE DOORS AND OPENERS ONLY” sets a clear limit. You cannot tell a real scope change from a spelling change without reading every record by hand.
HyreGarage analysis: Arizona cannot easily answer a question California answers in seconds: how many licensed garage door contractors are there, and who are they? Enforcement, consumer search and research all inherit that gap. The state regulates the work without being able to see it.
Our evidence is small. Sixteen records is a small slice of a state register. We are describing how a field is built, not measuring everyone in it.
What the sample shows is that the field can and does vary this way. That is a feature of how the register was designed, and it does not need a large sample to prove.
What do the ten states in our records require?
Sorted by how many garage door companies we hold for each state. The right-hand columns show plainly where our knowledge stops. We did not establish five of the ten, and saying so beats filling the cells.
| State | Companies in our records | Position on licensing this trade | How we know, or why we do not |
|---|---|---|---|
| Texas | 798 | No state licensing for construction contracting at all | TDLR license program list, retrieved directly |
| Florida | 791 | Not established by us | DBPR construction industry pages returned HTTP 403 to this environment |
| Arizona | 380 | ROC registration, no classification naming the trade — CR-5 with a free-text restriction | HyreGarage license records, 16 primary-verified records |
| Colorado | 358 | Not established by us | Not researched for this page |
| Georgia | 332 | Not established by us | Secretary of State board pages returned HTTP 403 to this environment |
| California | 312 | CSLB license with a classification that names the trade — D28 | HyreGarage license records, 315 primary-verified records |
| North Carolina | 296 | Not established by us | Not researched for this page |
| Washington | 277 | Registration, not licensing. Bond and insurance, no trade exam, no doors specialty among 63 | Washington L&I contractor pages, retrieved directly |
| Tennessee | 232 | Not established by us | Not researched for this page |
| Nevada | 126 | NSCB license with a sub-classification that names the trade — C-3D Overhead Doors | HyreGarage license records, 126 primary-verified records |
Company counts from HyreGarage data, 2026-09-06. “Not established by us” means we did not check the state’s position with a primary source. Do not read it as licensing either existing or missing. Florida’s DBPR construction pages and Georgia’s Secretary of State board pages both returned HTTP 403 to us on the retrieval date.
Which trades do states test, and where do garage doors fit?
Both states we checked directly regulate other trades heavily. Putting the lists side by side shows where garage doors sit.
Texas licenses elevator contractors
The TDLR program list includes air conditioning contractors, electricians, boiler inspectors, elevator contractors and water well drillers, among many others. It has no program for garage doors, overhead doors, or general or residential construction contracting.
An elevator and a garage door are both heavy loads that move up and down on a counterbalance. Only one is a licensed trade in Texas.
Washington registers instead of licensing
Registration requires “a Washington Continuous Contractor Surety Bond in the amount of: $30,000 for general contractors. $15,000 for specialty contractors”, plus “$200,000 in public liability and $50,000 property damage, or $250,000 combined single limit”.
There is no trade exam for general construction work. Our installer insurance study by state covers bond and insurance rules in more detail.
Washington does test some trades
L&I regulates 63 specialties that must register. Some trades, such as plumbing, electrical, elevators, boilers and asbestos, carry “additional requirements for education, examination, and licensing” on top of registration. Doors and garage doors are not among the named specialties.
California is the counter-example
D28, “Doors, Gates and Activating Devices”, is a CSLB class with its own scope. Our records show it working as a real trade category: 268 of 315 records carry it alone, not as an add-on to a general license.
Nevada sits in between
C-3D, “Overhead Doors”, is a sub-class, not a top-level class. But it names the work and it can be searched, which is what matters. 121 of our 126 Nevada records carry it.
What the pattern suggests
HyreGarage analysis: the trades that get exams are ones where the danger is hidden until it is disastrous: gas, electricity, a lift shaft, asbestos.
A garage door feels obviously dangerous, and obvious danger has often been a poor guide to what gets regulated. This is an observation about the pattern, not a policy recommendation.
How do you check a company when the state does not?
In a state with no class for this trade, checking falls to you. These questions give you real information.
Every state board with a register has a public search. Look the number up instead of accepting a photo of a card. Check the name on the license matches the name on the quote. A common gap is a license held by a different business from the one you are hiring.
In California, the answer you want is D28. In Nevada, C-3D. In a state with no such class, ask which class they hold and what it allows. Notice whether it describes this work or only allows construction in general.
They are different things that protect different people. Washington’s $30,000 general contractor bond is a state minimum, not a measure of the company. Ask for the certificate of liability insurance. Check it is current and names the right business.
A license belongs to a business. The person winding your springs may be an employee, a subcontractor or a day hire. Ask how long they have done this work, and whether the company’s workers’ compensation covers them. That matters if they are hurt on your property.
HyreGarage analysis: where the state does not define this trade, the written spec does the job a license class would. A quote naming the cycle rating, the design pressure and the impact standard tells you more than a registration number. Our quote checker walks through it.
It is a phrase, not a fact. The fact is a number you can look up and a certificate with a date on it.
What do these licensing terms mean?
- License
- Permission to practice a trade, usually granted on proof of skill (often an exam), and can be taken away. What Texas grants electricians and elevator contractors.
- Registration
- Being added to a list, usually on proof of a bond and insurance instead of skill. What Washington requires of construction contractors. The difference is real: registration tests money, licensing tests skill.
- Classification
- The fixed category a license is granted in, which sets its scope. CSLB D28 “Doors, Gates and Activating Devices” and NSCB C-3D “Overhead Doors” are classes that name this trade.
- CR-5 “As Restricted by the Registrar”
- The Arizona ROC class all 16 of our Arizona records carry. Its title names no trade. The scope is typed in separately as free text, so it cannot be searched or counted as a category.
- Primary-verified
- Our term for a record traced to the authority that issued it, not to a directory or listing site. Every license figure here is primary-verified. That is the only reason we publish counts from our own data at all.
- Qualifying party
- The named person whose qualifications support a company’s license. Arizona ROC records list one, as do others. Worth knowing because it is a person, and people leave.
What could we not find?
Five of our own ten states. We did not establish the position for Colorado, North Carolina or Tennessee. We could not reach the boards for Florida or Georgia: DBPR’s construction pages and Georgia’s Secretary of State board pages both returned HTTP 403 to us.
Those cells in the table say “not established by us” and mean it. We have not called any state unlicensed because a web request failed.
The other forty states. This is not a fifty-state survey and does not pretend to be. A real national list would mean reading fifty sets of laws and fifty class schedules. That is real work we have not done.
How big each register is. We can say what classes our records carry. We cannot say how many D28 holders CSLB has, or how many CR-5 holders Arizona has. That needs the full registers, not the part we hold. None of our counts is a count of licensed contractors in a state.
Whether classification predicts anything. The next question is whether states with a named class see better results: fewer complaints, fewer injuries, better work. That needs complaint and enforcement data next to the license data, and we hold neither.
Arizona at full scale. Sixteen records show that the restriction field varies. They do not show how much. A full pull of the Arizona register for this trade would answer that.
The irony is that doing so is hard for exactly the reason this page describes. You cannot filter a register on a field with no fixed list of names.

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.
Data as of HyreGarage license data and state board records, counted 2026-09-06.

Comparing companies in a state that defines nothing?
Ask each one for three things: the license or registration number, what its class covers, and the spring cycle rating in writing. The state may not check two of those for you.
