Hiring a general contractor for an addition or major remodel? Before you sign a contract, you need to know whether your contractor is legally licensed in your state—because requirements vary wildly, and a cheap bid from an unlicensed operator can turn into a nightmare. We'll walk you through licensing requirements by state and what to check before you hire.
Why Contractor Licensing Matters for Your Project
A licensed general contractor carries insurance, passes exams on building codes, and is accountable to your state's licensing board if something goes wrong. An unlicensed contractor operating illegally may vanish mid-project, leave you liable for accidents on your property, or produce work that fails inspection. For additions and major remodels—projects that often cost $50,000 to $250,000+—licensing is your primary protection.
The Two Main Licensing Models
States use one of two approaches: statewide licensing and local (city or county) licensing.
Statewide licensing means your state requires a single general contractor license to legally bid and perform work across the entire state. Examples include California, Florida, Texas, and New York. Statewide systems typically require 4–8 years of documented experience, an exam score (usually 70–75%), and continuing education credits every 2–3 years.
Local licensing means cities or counties issue their own permits and may or may not require a state license. States like Colorado, Oregon, and many Midwest states rely partly on local building departments to regulate contractors. In these areas, you'll still want proof of local licensing, insurance, and references—but requirements can differ between jurisdictions.
Key Licensing Requirements Across States
High-Barrier States (Strict Requirements)
California, Florida, and Texas have the highest standards. California requires 4 years of field experience, a written exam covering legal and technical knowledge, and a $300+ application fee. Florida mandates 1 year of experience as a licensed contractor and a Building Contractor exam. Texas requires 4 years of experience in the past 10 years, plus the TACO (Texas A&M Contractor Operating) exam. These states also require contractors to hold active workers' compensation insurance and bond requirements ranging from $12,500 to $50,000.
Medium-Barrier States (Moderate Requirements)
New York, Illinois, Washington, and Arizona typically require 1–3 years of verifiable field experience and a state exam. Application fees run $200–$500. Most require surety bonds of $25,000–$100,000 and proof of liability insurance (usually $300,000–$1,000,000 minimum).
Low-Barrier or Local-Only States
Colorado, Georgia, New Hampshire, and South Carolina have minimal or no statewide contractor licensing. However, most municipalities still require local permits and contractor registration. In these states, your responsibility is heavier—check your city or county's specific requirements and lean heavily on contractor reviews, references, and background checks.
What to Verify Before Hiring
When evaluating a general contractor for your addition or remodel, do this checklist:
- Search the state licensing board (usually online) for the contractor's license number, expiration date, and complaint history
- Request proof of liability insurance ($1 million minimum for residential work)
- Ask for workers' compensation insurance certificates for their employees
- Confirm bonding status (performance and payment bonds protect you if the contractor defaults)
- Check the Better Business Bureau for complaints and resolution history
- Get at least three written quotes with detailed scope, timeline, and materials listed
- Ask for references from similar projects (additions or significant remodels) completed in the last 2–3 years
Common Red Flags
Avoid contractors who:
- Can't produce a current license or claim they're "licensed in another state" (license doesn't transfer)
- Won't provide written contracts—only a verbal agreement or handshake
- Ask for large upfront payments (more than 10–20% of the total project cost)
- Don't carry insurance or claim it's "too expensive"
- Pressure you to pull permits yourself or skips permitting entirely
Finding and Comparing Contractors
Start by asking trusted neighbors or your architect (if you hired one) for referrals. Online platforms like Mercoly let you compare and find trusted general contracting providers in one place, filter by license status, and read verified customer reviews—saving time on vetting.
Frequently Asked Questions
Q: Do I need a licensed contractor for a room addition or is a handyperson enough? A: Room additions require building permits and inspections, so you need a licensed general contractor. Handypersons typically handle smaller repairs; additions fall outside their scope and insurability.
Q: What happens if I hire an unlicensed contractor and something goes wrong? A: You'll have no recourse through the state licensing board, your homeowner's insurance may deny claims related to unlicensed work, and you could face fines or be forced to have the work redone by a licensed contractor at your expense.
Q: How long does a general contractor license last? A: Most states require license renewal every 2–3 years, with continuing education requirements varying from 0 to 24 hours depending on the state.
