General contractor vs specialty license

Filed under Trade licenses
Verdict
- A general license is for projects involving two or more unrelated trades.
- One trade alone is specialty work, and a general license does not automatically cover it.
- A specialty holder who takes on a second unrelated trade has the same problem in reverse.
| Item | General | Specialty |
|---|---|---|
| Defined by | Two or more unrelated trades in the project | One trade |
| Exam | Broad across the trades that meet in a building | Deep in one |
| Typical work | Whole builds, multi-trade remodels | Re-roofs, service upgrades, re-pipes |
| Subcontracting | Normal and expected | Usually limited to your own trade |
| Covers the other? | Not by itself — in California a B may prime a one-trade job only by holding that class or subcontracting it | No — a second unrelated trade needs a general |
| Adding the other | An additional classification and usually another exam | Same |
§ 1The rule
California states the scheme in Business and Professions Code § 7055, and its shape is widely copied. The families are A General Engineering Contractor, B General Building Contractor, B-2 Residential Remodeling Contractor, C Specialty Contractor — with everything under C a single-trade classification.
What matters is that the general class is defined by the presence of two unrelated trades. It is not a bigger license that contains the small ones; it is a differently shaped one.
§ 2Three cases
Work through your own job like this
- Stand-alone re-roof. One trade. Specialty. In California a B holder may take it as the prime contractor only by holding the roofing class or subcontracting the roofing to a licensed roofer (B&P § 7057(b)); as a subcontractor, only the roofing class will do.
- Whole-house remodel. Framing, electrical, plumbing, finish. General, and it stays general even if you subcontract every trade.
- Re-pipe with drywall repair. Arguably two trades — and “arguably” is where boards and lawyers live. Read your board’s scope wording before you sign.
§ 3Holding both
If your work regularly crosses the line both ways, the decision is about timing. California prices an added classification at $230 on an existing license, against $150 when it rides an original application — so settle general or specialty, or both, before you file. How adding a class works, and why not to over-collect them, is in contractor license classifications.
Two of the trade ladders, plumbing and HVAC, are set side by side in plumbing vs HVAC license paths.
§ 4Getting it wrong
Nobody stops you bidding outside your class. The question surfaces at complaint time, and at that point working outside your classification carries the same exposure as working unlicensed — including the effect on your right to be paid. See working unlicensed.
