Do Subcontractors Need Their Own License?

Whether subcontractors need their own license depends on what trade they are performing and which state the work is in — not just whether their general contractor is licensed. Many homeowners assume a licensed GC covers all workers on the job. That assumption can lead to serious legal and financial exposure.

Do subcontractors need their own contractor license?

Yes, in most states, subcontractors performing specialty trade work — electrical, plumbing, HVAC, roofing — must hold their own separate trade license regardless of whether they are working under a licensed general contractor. The general contractor's license covers overall project management and general construction work, not specialized trade work performed by others.

• Electricians must hold electrician licenses in virtually every state
• Plumbers must hold plumber licenses regardless of who the GC is
• HVAC subcontractors need their own HVAC or mechanical contractor licenses
• Roofing subcontractors may need separate roofing contractor licenses in many states
• A GC's license does not “cover” unlicensed trade subs in almost any jurisdiction

What happens if an unlicensed subcontractor does work on my home?

If an unlicensed subcontractor performs specialty trade work on your home, the permit may be invalid, the work may fail inspection, and you may have no legal recourse against the subcontractor if the work is defective. In some states, knowingly permitting unlicensed work can create liability for the homeowner. An unlicensed electrician's work that causes a fire may complicate your insurance claim if the insurer determines the work was unpermitted and unlicensed.

Who is responsible if a subcontractor is unlicensed — the GC or the homeowner?

The general contractor is primarily responsible for ensuring that subcontractors hold required licenses. Most state contractor licensing laws impose this obligation on the GC. However, homeowners are not entirely insulated — if you had reason to know a subcontractor was unlicensed and allowed them to proceed, you may have limited recourse under some state laws. The practical takeaway: ask the GC to provide license numbers for all specialty trade subcontractors before work begins.

• GC is legally responsible for hiring only properly licensed subs in most states
• Ask for subcontractor trade license numbers before work starts
• Verify each sub's license directly with the relevant state board
• Include a contract provision requiring the GC to use only licensed subcontractors

How do I find out which subcontractors will work on my project?

Ask the general contractor for a list of all specialty trade subcontractors they plan to use before signing the contract. Legitimate GCs know their subcontractors and can provide this information readily. For each specialty sub, request their trade license number and the state board it was issued by. You can then verify each license independently. If a GC resists disclosing subcontractors, treat that as a red flag.

Do subcontractors need their own general liability insurance?

Yes — specialty trade subcontractors should carry their own general liability insurance in addition to holding a trade license. The GC's policy may or may not cover damage caused specifically by a sub's work, and many policies explicitly exclude damage from work performed by subcontractors. Always ask the GC to provide certificates of insurance for any major specialty subcontractors being used on your project.

• Ask for subcontractor certificates of insurance, not just the GC's policy
• Verify the sub's insurance is current and covers the period of their work
• GC policies often have exclusions for subcontractor-caused damage
• Workers' comp for subcontractors is a separate issue from the GC's workers' comp

Are sole-proprietor subcontractors considered employees or contractors?

This distinction matters for workers' compensation liability. A sole-proprietor subcontractor who lacks their own workers' comp coverage may be reclassified as an employee of the GC (or even the homeowner) under some state laws, creating liability exposure if they are injured on your property. In states like California, the workers' comp rules around subcontractors are particularly strict. Always confirm subcontractors have their own coverage or are expressly covered under the GC's policy.

How common is unlicensed subcontractor work?

According to the Bureau of Labor Statistics, an estimated 10–20% of construction workers in the United States are misclassified or operating outside proper licensing requirements at any given time. Trade associations estimate unlicensed subcontractor work is particularly prevalent in roofing, HVAC, and general carpentry. The problem is worst after major natural disasters when contractor demand spikes rapidly.

How can I verify subcontractor credentials quickly?

Each specialty trade has its own state licensing board — electricians through the state electrical board, plumbers through the state plumbing board, and so on. You can verify each subcontractor by searching those boards directly. Alternatively, CheckLicensed.com can verify contractor and specialty trade license status from official state sources for $14.99 per check, covering both GCs and specialty trade licensees across dozens of states.
