The quick answer
- 1A state contractor's license is required in nearly every state for construction work above $500–$1,000. Exam, experience documentation, and a background check are standard requirements.
- 2A surety bond (typically $10,000–$25,000 for a new GC) is required to get licensed. The bond protects clients and the state — it's not insurance for you.
- 3Commercial general liability and workers' comp are non-negotiable. Most GCs carry $1–2 million per occurrence in GL coverage and are required by law to carry workers' comp as soon as they hire.
- 4Building permits are project-specific — separate from your contractor's license. You pull permits job by job from local building departments, and inspections follow at code-defined milestones.
1. Understand the license structure before you apply
Construction licensing in the U.S. is a patchwork. There's no federal contractor's license. Each state runs its own program, and many cities and counties layer additional requirements on top.
The key distinction is between a general contractor (GC) license and a specialty contractor license. A general contractor's license lets you manage entire construction projects — you can hire licensed subcontractors for electrical, plumbing, HVAC, and other regulated trades. A specialty license covers a single trade and typically won't let you manage work outside that discipline.
Most residential and commercial construction companies start with a GC license. If your work is focused on a specific trade (roofing, concrete, framing, HVAC), a specialty license may be the more direct path — the exam is narrower, the experience requirements are clearer, and the bond amount is often lower.
A few states — Texas being the most notable — don't issue a statewide general contractor's license. In Texas, licensing is handled at the city level. Houston, San Antonio, and Dallas all have their own contractor registration programs. If you're starting in a state like this, you need to check with every city where you plan to work.
2. Licensing and compliance requirements, step by step
Here's the sequence that works for most states.
LLC or business entity formation
Form your LLC before applying for a contractor's license. Construction companies have substantial liability exposure — property damage, bodily injury on job sites, and contract disputes. An LLC creates a legal wall between business liabilities and personal assets. File Articles of Organization, get an EIN from the IRS (free, 10 minutes online), and open a dedicated business bank account. Note: some states require the business to be licensed, not the individual, which makes entity formation a prerequisite for the license application.
Contractor's license exam and application
Most state contractor boards require: (1) passing a written exam covering construction law, project management, and trade-specific knowledge; (2) documenting 3–5 years of qualifying experience in construction; (3) providing business financial statements showing you have the capital to operate; (4) passing a background check. Prep courses for the exam are widely available — budget 40–80 hours of study for the business and law portion alone. Some states accept national exams (like PSI or Prometric) while others have proprietary tests.
Contractor's license bond (surety bond)
Most states require a contractor's license bond as a condition of licensure. Bond amounts vary: California requires a $25,000 bond for Class B General Building Contractor; Florida requires a $10,000 bond for the Certified General Contractor. You pay an annual premium to a surety company — typically 1–3% of the bond amount for good credit. If you have poor credit, the premium can reach 5–10%. The bond is renewed annually with your license.
Commercial general liability insurance
General contractor GL insurance covers bodily injury, property damage, and completed operations claims. State contractor boards typically require proof of GL coverage ($300,000–$1,000,000 per occurrence) as part of the license application. Most commercial clients and property owners will require a certificate of insurance before you step on site — often requiring themselves as an "additional insured." Rates scale with your annual revenue and payroll.
Workers' compensation insurance
Construction is a high-risk industry, and workers' comp is mandatory in virtually every state as soon as you have an employee. Rates for construction are among the highest of any industry — typically $10–$25 per $100 in payroll for general construction work, higher for roofing, electrical, and structural work. If you're a sole proprietor with no employees, you can often waive workers' comp for yourself — but the moment you hire, you're required to carry it.
General business license
Separate from your contractor's license. Most cities require a general business license for any business operating within city limits. Some cities also require contractor-specific registration on top of the general business license. If you plan to work in multiple cities or counties, you may need to register in each one.
Building permits (project by project)
Building permits are project-specific. You apply for each job separately, typically submitting drawings or plans, a description of work, and the property address. The building department reviews for code compliance and issues a permit. Inspections are required at framing, rough mechanicals, insulation, and final. Working without a permit can result in stop-work orders, fines, and orders to demolish unpermitted work — all of which come out of your pocket.

3. State-by-state contractor licensing highlights
The licensing structure varies significantly by state. Here are the key facts for the largest construction markets:
- California: The Contractors State License Board (CSLB) issues licenses in 44 specialty classifications plus the Class A (Engineering), Class B (General Building), and Class C (Specialty) tiers. The Class B license is what most residential GCs need. Exam pass rates run 40–50%. Bond requirement: $25,000. Experience requirement: 4 years at the journeyman or foreman level within the last 10 years.
- Florida: The Department of Business and Professional Regulation (DBPR) issues Certified General Contractor (CGC) and Certified Building Contractor (CBC) licenses. The CGC exam covers four parts: project management, business and finance, building codes, and site preparation. Bond: $10,000–$100,000 depending on financial stability. Florida also has a Registered contractor tier for work limited to a single county.
- Texas: No statewide GC license — but every major city has its own contractor registration. Houston requires a contractor registration for work over $5,000. Dallas requires registration for all structural and mechanical work. Electrical and plumbing work requires a state license from TDLR regardless of location.
- New York: New York City is the most regulated market — the NYC Department of Buildings issues a General Contractor License separate from any state license. Applicants need 7 years of experience, must pass a written and practical exam, and carry $1 million in GL insurance. Outside NYC, county-level requirements vary widely.
- Arizona: The Registrar of Contractors (ROC) licenses contractors in three categories: commercial, residential, and dual. Exam required. Surety bond required. Arizona is particularly active in enforcement — complaints against unlicensed contractors regularly result in cease-and-desist orders and fines up to $15,000.
- Washington: The Department of Labor & Industries (L&I) issues a Contractor Registration (not a "license") for general contractors. Registration requires a $12,000 bond for general contractors and $6,000 for specialty contractors. There's no exam for registration, but electrical and plumbing work requires a specialty license with an exam.
4. OSHA compliance requirements for construction companies
OSHA 29 CFR 1926 governs construction safety. As a general contractor, you're responsible for OSHA compliance not just for your own employees, but for all workers on the job site you control. Key requirements:
- OSHA 10-Hour training: Many states (New York, Massachusetts, Connecticut, Nevada, and others) mandate that all construction workers on public projects complete OSHA 10-Hour training. Even where not legally required, it's increasingly required by project owners and GCs as a condition of site access.
- Fall protection: Falls are the leading cause of construction fatalities. OSHA requires fall protection (guardrails, safety nets, or personal fall arrest systems) at heights of 6 feet or more in residential construction and 10 feet in some commercial contexts. This is the most-cited OSHA violation in construction, year after year.
- Hazard Communication (HazCom): Any job site using hazardous chemicals (paints, solvents, adhesives, treated lumber) must maintain Safety Data Sheets (SDS) and train workers on chemical hazards. GCs are responsible for ensuring subcontractors on their sites comply.
- Excavation and trenching: Trenches deeper than 5 feet require a protective system (sloping, shoring, or trench box). Trenches deeper than 20 feet require a registered professional engineer to design the protective system. Cave-ins kill more workers than any other excavation hazard.
- Scaffolding: Scaffolding must be erected and inspected by a competent person. Planks must be secured, guardrails required above 10 feet, and workers must be trained on scaffold hazards. Scaffold violations are consistently among OSHA's top 10 citations for construction.

5. What a construction company actually costs to start
Here's a realistic breakdown for a small general contractor starting a residential construction company:
| Item | Low | High |
|---|---|---|
| LLC formation + registered agent (year 1) | $150 | $700 |
| Contractor license exam + application fees | $300 | $800 |
| Exam prep course | $200 | $600 |
| Contractor's license bond (year 1 premium) | $150 | $750 |
| Commercial general liability insurance (year 1) | $2,000 | $8,000 |
| Commercial auto insurance (year 1) | $1,500 | $5,000 |
| Tools and initial equipment | $3,000 | $15,000 |
| Work truck or van (used) | $8,000 | $35,000 |
| Business license + local registrations | $100 | $500 |
| Accounting software + initial bookkeeping setup | $300 | $1,000 |
| Total | $15,700 | $67,350 |
These are pre-revenue costs — before you've landed your first job. Add working capital to cover materials deposits and payroll between invoice and collection on your first projects, and a realistic startup budget is $30,000–$100,000 for a properly capitalized construction company.
6. Where new construction companies run into trouble
- Starting work before the license is in hand. This is the most common and most expensive mistake. Unlicensed contracting is a criminal offense in most states, and any work performed while unlicensed can result in the client voiding the contract and demanding their money back — even on completed projects.
- Misclassifying employees as independent contractors. Construction companies often try to reduce costs by 1099-ing workers who are legally employees. The IRS and state labor agencies audit construction companies heavily for this. Penalties include back taxes, interest, and fines — plus liability for workers' comp claims from misclassified workers who get injured.
- Skipping the lien process. Mechanics' liens are your primary protection for getting paid in construction. You typically need to serve a preliminary notice to the property owner and lender within the first 20–30 days of starting work. Many contractors don't do this and lose their lien rights — meaning they're unsecured creditors if the client doesn't pay.
- Pulling permits only when clients insist. Some contractors skip permits to save time and money. When work gets sold, refinanced, or inspected, unpermitted work is discovered and the current owner is forced to get permits or demolish the work. The contractor who did the work often faces claims for this cost years after the job.
- Inadequate contract documentation. Verbal agreements and loose scopes of work are the source of most construction disputes. Every job needs a written contract covering scope, materials specifications, change order process, payment schedule, and dispute resolution. A construction attorney can draft a solid template for $500–$1,500.
- Not carrying enough insurance for larger projects. A $1 million GL policy is adequate for small residential work. Once you're doing commercial projects, additions, or high-end custom homes, you need to verify that your coverage limits match the project value. A single claim on an underinsured project can end a small construction company.
Frequently asked questions
Do you need a license to start a construction company?
In virtually every state, yes. Most states require a contractor's license issued by the state contractor board for any construction work above a low dollar threshold ($500–$1,000 in most states). Unlicensed contracting is a misdemeanor or felony in many states — it can result in fines, project shutdowns, and personal liability for work performed. A few states (like Texas) don't require a statewide general contractor license but have extensive local licensing requirements at the city level.
How much does it cost to get a contractor's license?
Exam fees run $75–$250. License application fees run $100–$500. Bond premiums depend on your bond amount and credit score — for a $15,000 bond, expect to pay $150–$450 per year. Insurance (GL + workers' comp) is the biggest single cost: $3,000–$15,000 per year for a small contractor. Total startup cost for just the licensing and compliance side: $1,000–$3,000 in year one before you price a single job.
What is a contractor's license bond?
A contractor's license bond (also called a contractor's surety bond) is a three-party agreement between you, the state licensing board, and a surety company. If you fail to complete a job, violate licensing laws, or cause financial harm to a client, the bond provides a financial remedy — up to the bond amount. The bond is not insurance for you; it protects consumers and the state. Bond amounts range from $5,000 to $100,000+ depending on the state and license type. You pay an annual premium of 1–3% of the bond amount if your credit is good.
What insurance does a construction company need?
Commercial general liability ($1–2 million per occurrence) is required for most licenses and job sites. Commercial auto covers your vehicles and equipment in transit. Workers' comp is mandatory in almost every state the moment you have an employee. For larger projects, you may also need builder's risk insurance, umbrella coverage, and professional liability (if you're doing any design-build work). A complete insurance package for a small general contractor typically runs $5,000–$20,000 per year depending on payroll and revenue.
Can you start a construction company with no experience?
Most states require documented work experience as a condition of getting licensed — typically 3–5 years of journeyman-level experience in the trade. California requires 4 years of experience at the journeyman or foreman level. Florida requires construction industry experience or completion of a state-approved exam prep course. You can work as an unlicensed subcontractor under a licensed contractor to build qualifying experience before applying for your own license.
What is the difference between a general contractor license and a specialty contractor license?
A general contractor (GC) license allows you to oversee entire construction projects and hire subcontractors for specialty trades. A specialty contractor license covers a specific trade — electrical, plumbing, HVAC, roofing, concrete, etc. GC licenses typically require broader experience and higher bond/insurance amounts. In California, the Class B General Building Contractor license requires at least two unrelated trades on a project. Specialty licenses are easier to obtain and can be more profitable if you focus on a specific niche.
Do construction companies need permits for every job?
Building permits are project-specific approvals from the local building department — separate from your contractor's license. Most structural work, electrical, plumbing, HVAC, and exterior alterations require a permit. Permits are typically pulled by the licensed contractor, not the property owner (though owners can pull permits for their own homes in most jurisdictions). Pulling a permit triggers inspections at key milestones. Working without a required permit can result in stop-work orders, fines, and require demolishing unpermitted work.
How do I find the exact license requirements in my state?
Contractor licensing requirements vary by state, county, and city — and many jurisdictions have multiple overlapping requirements. For the exact agencies, fees, and application forms in your area, use the StartPermit permit database.
