General Contractor License Training Requirements
General contractor license training requirements vary sharply by state, from an 8-hour pre-license course in Virginia to a 60-hour prelicensure education requirement in Michigan, with some states (Washington) requiring no formal pre-license training at all. Most states that do require training treat it as separate from documented work experience, meaning the hours are required on top of your years in the trade, not instead of them.
This is the detail that catches experienced contractors off guard when they move states. Fifteen years of hands-on construction experience doesn’t exempt you from a new state’s prelicensure course; the education requirement exists to cover that state’s specific licensing law and business practices, not general trade skill you may already have.
Which states require the most pre-license training hours?
Based on our research, Michigan’s 60-hour prelicensure requirement for the Residential Builder license is the highest we found, followed by Oregon’s 16-hour requirement and Utah’s combined 30 hours (a 25-hour general course plus a 5-hour business and law course for general classifications). Virginia’s 8-hour course sits at the lower end among the states we researched that require any pre-license training at all.
| State | Pre-license training hours |
|---|---|
| Michigan (Residential Builder) | 60 hours |
| Utah (general classifications) | 30 hours combined |
| Oregon | 16 hours |
| Virginia | 8 hours |
| Washington | None required |

Can education substitute for experience instead of adding to it?
In some states, partially. California’s CSLB allows qualifying education, apprenticeship, or technical training to substitute for up to 3 of the 4 required experience years, as long as at least 1 year remains practical, hands-on experience. This is different from a mandatory pre-license course like Virginia’s or Michigan’s, which is required regardless of how many experience years you already have. Confirm whether your target state treats education as a substitute for experience or as an additional requirement layered on top, since the two models work very differently.
Does continuing education apply after I’m licensed, not just before?
Yes, in several states we researched. Massachusetts requires 12 continuing education units per 2-year Construction Supervisor License renewal cycle. Georgia tracks continuing education for Residential Basic and Residential Light Commercial licensees through CE Broker. Maryland’s MHIC license, by contrast, doesn’t require continuing education at renewal at all. Confirm your specific state’s post-licensure requirement separately from its pre-license training requirement, since states that are strict on one aren’t necessarily strict on the other.
Do online pre-license courses count?
Often, yes, if the course provider is state-approved, but “online” and “approved” aren’t the same thing. Several states maintain a specific list of approved prelicensure education providers; a generic online construction course that isn’t on that list typically won’t satisfy the requirement, regardless of how many hours it covers. See our online general contractor license page for more on which parts of the licensing process can legitimately happen online.
Why does Washington skip pre-license training entirely?
Because Washington’s L&I contractor registration substitutes bonding and insurance verification for a tested body of trade knowledge, and pre-license education exists in other states specifically to prepare candidates for that exam. Without a state trade exam, there’s no exam to prepare candidates for. See our washington general contractor license page for the full detail on that structural difference.

FAQ
Which state requires the most pre-license training hours? Michigan, at 60 hours for its Residential Builder license, the highest figure among the states we researched.
Does my construction experience exempt me from a state’s pre-license course? Generally no; most states requiring pre-license training apply it regardless of your years of hands-on experience, though some states let education substitute for a portion of the experience requirement itself, a different mechanism.
Do I need continuing education after I’m already licensed? It depends on the state; Massachusetts and Georgia require ongoing continuing education for renewal, while Maryland’s MHIC license doesn’t.
Can I complete pre-license training entirely online? Often yes, but only through a state-approved provider; confirm your target state’s approved-provider list before enrolling in any online course.
Does Washington require any pre-license training at all? No. Washington’s L&I registration process has no state trade exam and no formal pre-license training requirement, substituting bonding and insurance verification instead.
Bottom line: pre-license training hour requirements range from none to 60 hours depending on the state, and education substituting for experience is a genuinely different mechanism from a mandatory pre-license course, so confirm which model your target state uses before assuming your prior experience covers the gap. Confirm current requirements directly with that state’s board.
