How to Start a Construction Company: Licenses, Bonds, and What It Actually Costs (2026 Guide)

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.

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:

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. The complete construction insurance stack

A single policy won't cover everything. Construction involves multiple overlapping risk layers, and serious GCs carry several policies working in concert. Here's what the full insurance stack looks like and when each policy applies:

Small residential GCs typically start with CGL, workers' comp, and commercial auto. As project size grows above $500K, add builder's risk and umbrella. If you're doing any design-build or providing drawings, add professional liability before your first such project — CGL doesn't cover design errors.

7. Bonding requirements and prevailing wage law

If you pursue public projects — schools, government buildings, roads, water treatment plants — you'll encounter a different compliance universe than private work. The key elements are construction bonds and prevailing wage requirements.

Construction bond types

Not all surety bonds are the same. Your contractor's license bond is a standing license requirement. Project bonds are specific to individual contracts:

• Bid bond: Submitted with a bid on a public project. Guarantees that if you win the bid, you'll enter the contract at the bid price and provide the required performance and payment bonds. Bid bond amounts are typically 5–10% of the bid price. If you win and refuse to sign, the bond pays the difference between your bid and the next-highest bid.
• Performance bond: Guarantees you will complete the project according to the plans, specifications, and contract terms. If you default, the surety either steps in to complete the project or pays damages up to the bond amount (typically 100% of the contract value). Performance bonds are required by the federal Miller Act on all federal construction contracts over $150,000, and by most state "Little Miller Acts" on state-funded work.
• Payment bond: Guarantees that subcontractors, suppliers, and laborers on the project will be paid. Required on the same federal and state projects as performance bonds. Without a payment bond, a sub who doesn't get paid could file a mechanics' lien against the project — which can halt funding and cause the owner enormous problems. The payment bond eliminates that risk for the owner.

Performance and payment bonds are typically packaged together and cost 0.5–3% of the contract value. Your surety credit capacity — the maximum dollar value of projects you can bond at once — is based on your net worth, liquidity, and project backlog. New construction companies usually start with a bonding capacity of 5–10x net worth.

Federal Davis-Bacon Act

The Davis-Bacon Act of 1931 requires that workers on federally funded construction contracts over $2,000 be paid the "prevailing wage" for their trade in the local area. Prevailing wages are set by the U.S. Department of Labor and published in wage determinations that are incorporated into every covered contract. The prevailing wage includes both a base hourly rate and a fringe benefit component (health insurance, pension, apprenticeship, etc.).

Davis-Bacon applies to construction, alteration, and repair of public buildings and public works financed by federal funds. This includes projects funded by federal grants to states and municipalities — which covers a large portion of public school, road, and infrastructure work. As a GC, you're responsible for Davis-Bacon compliance for all your subcontractors as well.

State prevailing wage laws ("Little Miller Acts")

Over 30 states have their own prevailing wage laws that apply to state-funded projects — often called "Little Davis-Bacon" laws. These may have lower thresholds than the federal act ($1,000–$25,000 depending on the state) and use state-specific wage rates determined by each state's department of labor. Some states (like California) have wage rates significantly higher than federal Davis-Bacon rates.

Prevailing wage violations are serious. Penalties include back pay for all affected workers, debarment from future public work, and in some states, criminal charges for willful violations. Before bidding any government job, confirm whether prevailing wage applies and obtain the applicable wage determination for every trade you'll use.

8. Revenue model by project type

Construction revenue varies enormously by market segment. Understanding the contract ranges and typical margins for different project types helps you choose where to focus — and how to price your work.

Gross margin is revenue minus direct costs (labor, materials, subcontractors, equipment). Net profit after overhead (office, insurance, vehicles, admin) for most small GCs runs 5–12%. The most profitable construction companies focus on a narrow niche, build a reliable subcontractor network, and use cost-plus or time-and-materials contracts to reduce scope risk.

9. 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.
