Garage door contractor licensing by state

What each state actually requires

This table is built the slow way. Every row was read off the licensing board's own site, and the date it was read is printed next to it. The "licensing by state" pages that dominate this search disagree with each other and, more often, with the boards — so none of them are used here as a source.

How this table was built

All 51 jurisdictions — 50 states and the District of Columbia — have now been read directly off the licensing board's own site, and each row carries the date it was read. It shipped incomplete before that was true, naming the states it had not checked rather than padding them out, because a wrong licensing claim sends someone to hire a contractor who cannot legally do the work, or tells them to skip a check their state actually requires.

Two states name garage doors specifically. California licenses the work under C-61/D-28 and Florida certifies a Garage Door Installation Specialty Contractor with its own trade exam. Everywhere else it falls under a general, residential or home improvement licence, or under nothing at state level.

Where a threshold decides it, the range is wide enough to matter: $600 in Michigan, $2,000 in Arkansas and Idaho, $2,500 in West Virginia, $10,000 in Alabama, and $40,000 in North Carolina. The same garage door job needs a licence in one state and not in the state next to it.

What a licence proves, and what it does not

A contractor licence means the holder met a state's bar for paperwork: an exam in some states, proof of experience, a surety bond, liability insurance, sometimes a credit check. In Pennsylvania it is explicitly a registration rather than a licence, and the Attorney General's own guidance is clear that it is not a skills test.

None of that is a safety credential. No state exam we found tests whether the holder understands how much energy a wound torsion spring stores. A licence gives you recourse — a bond to claim against, a board to complain to, an insurer if something is damaged. Recourse matters. It is not the same as competence, and a page that tells you a licence number makes spring work a safe purchase is selling you something.

Why this question matters more for springs than for sensors

Most garage door jobs are low-stakes. If a photo eye gets aligned badly or a remote is programmed wrong, the cost of a mistake is an afternoon. The counterbalance system is different, and it is the reason we publish this table at all.

Under 16 CFR 1211.16(b) the federal government dictates the exact words every opener manual must carry, and one of them is: “Have a qualified service person make repairs to cables, spring assemblies and other hardware.” That sentence is in the manual that shipped with your opener. It does not say a licensed person. It says a qualified one — and in the fourteen states that license no general contractor at all, there is no state licence to tell you which is which.

So on spring, cable, drum and bottom-bracket work, the licence check is the floor rather than the ceiling. Ask what else the company carries: manufacturer training, an IDEA certification, years doing this specific work, and whether the technician replacing one spring will replace both.

Checking a licence takes about a minute

Where a state runs a public lookup, it is linked in the table. Search by the company name or the licence number on the estimate, and check three things: that the licence is active rather than expired or suspended, that the name on it matches the name on your paperwork, and that the classification covers the work. A licence in a trade that has nothing to do with doors is not coverage.

Two details catch people out. A licence held by a parent company does not automatically cover a franchisee operating under a different name. And in states where a bond is required, the bond amount is usually far smaller than a full door replacement — Washington sets $30,000 for general and $15,000 for specialty contractors — so it is a partial backstop rather than a guarantee.

If your state does not license this work

Fourteen jurisdictions license no general contractor at all: Texas, Ohio, Illinois, Colorado, Indiana, Missouri, Oklahoma, Kentucky, Kansas, South Dakota, Wyoming, New Hampshire, Maine, and New York outside its named counties. That is not a warning sign about the trade; it is a gap you fill with other checks.

Ask for a certificate of insurance sent directly from the insurer rather than forwarded by the contractor. Confirm the company pulls a permit where your city requires one for opener or structural work, since the permit puts a building inspector on the job. Get the estimate in writing with part numbers on it, because on springs the specification is the price. And check whether your city or county licenses contractors even though the state does not — many do.

Corrections

Licensing rules change, thresholds get raised, and boards reorganise. Every row above carries the date it was read so you can judge how stale it might be. If you find a row that no longer matches what the board says, we would rather hear about it than have it sit here being wrong.

Jurisdiction notice. Requirements are state law and change without notice. This page is not legal advice. Verify with the board linked in your row before relying on it, and check your city and county separately — local licensing can apply even where state licensing does not.
