Contractors bonding and insurance questions come up at every stage of a GC's growth. New contractors want to know what coverage they need. Growing firms need to expand their bonding capacity. Multi-state operators need to navigate different requirements across jurisdictions.

This guide answers the most common questions GCs ask about bonding and insurance, organized by topic.

Questions About Getting Started

What bonding and insurance do I need to start a construction company?

At minimum, you need general liability insurance ($1M/$2M is the standard starting point), workers' compensation insurance (mandatory in 49 states), commercial auto insurance for business vehicles, and a contractor license bond in states that require one.

Bonding capacity for project bonds takes time to build. Start by establishing a surety relationship even before you bid bonded work. Your surety broker will evaluate your financial statements and set initial limits.

How much will my first-year bonding and insurance cost?

First-year costs depend on your revenue, payroll, project types, and location. A new GC with $1M in projected revenue can expect roughly the following.

Coverage	Estimated Annual Cost
General liability	$3,000-$8,000
Workers' comp	$5,000-$25,000 (varies by trade)
Commercial auto	$2,000-$6,000
Umbrella ($1M)	$1,500-$4,000
Contractor license bond	$500-$2,000
Total	$12,000-$45,000

These are rough estimates. Actual costs depend on your state, trade classifications, claims history, and coverage limits.

Do I need bonding if I only do private work?

You do not legally need project bonds for private work unless the contract requires them. However, many private owners on projects over $1M require performance and payment bonds. Having a bonding program in place expands your bidding opportunities significantly.

Questions About Costs and Pricing

Why did my insurance premium increase?

Premium increases typically result from one of four factors: claims filed against your policy, industry-wide rate increases by carriers, changes in your payroll or revenue (which affect premium calculations), or changes in your experience modification rate.

Review your premium breakdown with your broker. Identify which factor drove the increase and whether you can address it. Claims-driven increases improve over time if you reduce incident frequency.

How can I lower my bonding costs?

Five strategies reduce bonding premiums. Strengthen your balance sheet by retaining earnings. Improve your personal credit score. Build a track record of completed bonded projects. Negotiate annual account programs instead of per-project bonds. Work with a construction-specialized surety broker who has access to competitive markets.

Is the bond premium a one-time cost or annual?

Bond premiums are typically charged at bond issuance. For multi-year projects, the surety may charge a continuation premium at each anniversary. The initial premium usually covers the first year. Continuation premiums run 50-75% of the initial rate.

Questions About State Requirements

Which states require contractor license bonds?

States with contractor license bond requirements include California ($25,000), Oregon ($75,000), Washington (varies by type), Nevada ($5,000-$100,000), and Arizona ($5,000-$15,000). Other states have local or municipal bond requirements even without statewide mandates.

How do workers' comp requirements vary by state?

All states except Texas mandate workers' compensation. The employee threshold varies. Florida requires coverage for any employer with one or more construction employees. Georgia requires coverage with three or more employees. Most states mandate coverage for all construction employers regardless of employee count.

Texas allows employers to opt out of workers' comp, but non-subscribers face unlimited liability for workplace injuries and cannot use many common legal defenses. Most GCs in Texas carry workers' comp despite the opt-out option.

Do indemnification rules differ by state?

Yes. Anti-indemnity statutes govern what indemnification language is enforceable in construction contracts. Most states prohibit broad-form indemnification (requiring one party to indemnify another for the other party's own negligence). Some states allow intermediate-form indemnification. A few states have minimal restrictions.

Your subcontract indemnification clause must comply with the law of the state where the project is located. Using a single template across states without state-specific modifications creates unenforceable provisions.

Questions About Subcontractor Requirements

What bonding and insurance should I require from subcontractors?

Use a tiered approach based on subcontract value and risk. At minimum, every sub needs general liability ($1M/$2M), workers' comp (statutory), and commercial auto ($1M). Add umbrella coverage for subs with contracts over $100,000-$200,000. Require bonds on subcontracts over $500,000 or on critical-path trades.

What if a subcontractor cannot get bonded?

A sub who cannot obtain a bond may have financial problems, a poor completion record, or limited experience. Evaluate the risk carefully. Options include requiring a larger retainage, obtaining a letter of credit instead, using a different sub, or self-insuring the default risk (only advisable on small scopes with low exposure).

How do I verify subcontractor insurance is valid?

Request a current certificate of insurance. Verify the carrier's A.M. Best rating. Confirm that additional insured endorsements name your company correctly. Check that policy dates cover the project duration. For highest assurance, contact the carrier directly to confirm active coverage.

Automated compliance platforms streamline this process by tracking expiration dates, flagging gaps, and alerting your team when action is needed.

Questions About Claims and Disputes

What happens when I file a bond claim?

Bond claims follow a structured process. You notify the surety in writing of the contractor's default. The surety investigates by reviewing contract documents, inspecting the work, and interviewing both parties. The surety chooses a remedy: financing the original contractor to complete, hiring a replacement, or paying the bond amount.

The entire process typically takes 30-90 days. Complex claims may take longer.

Does filing an insurance claim raise my premiums?

Yes. Claims affect your loss ratio and experience modification rate. Workers' comp claims directly impact your EMR, which determines your premium rate. General liability claims affect your loss ratio, which carriers consider at renewal. However, large claims have more impact than small ones, and the effect diminishes over three to five years.

Can my surety drop me after a claim?

Yes. A surety can decline to issue new bonds after a claim. However, the existing bonds remain in force. To maintain your bonding program, communicate with your surety throughout any claim situation. Demonstrate that the claim was an isolated event, not a systemic problem. If your current surety exits, your broker can find a replacement, though terms may be less favorable.

FAQs

What is the difference between bonding and insurance? Bonding guarantees contractor performance. Insurance covers financial losses from covered events. Bonds are underwritten based on the contractor's ability to perform. Insurance is underwritten based on risk exposure.

How long does it take to get a surety bond? Standard bonds take 3-10 business days. Rush requests may process in 24-48 hours. New surety relationships take 2-4 weeks for the initial setup.

What happens if my insurance lapses? Operating without insurance exposes you to unlimited personal and business liability. Most contracts treat lapsed insurance as a default. Your contractor license may be suspended in states that require proof of insurance.

Do I need separate insurance for each project? Your general liability, workers' comp, and auto policies typically cover all projects. Builders' risk and project-specific coverage may need separate policies per project. Check with your broker when taking on projects with unusual risk profiles.

Can I bond a project that exceeds my current bonding capacity? You can request a capacity increase from your surety. Provide updated financial statements and a project-specific analysis. Allow 30-60 days for the underwriting review. Not all requests are approved.

What credit score do I need for bonding? Personal credit scores above 700 qualify for standard bonding programs. Scores between 650-700 may qualify with higher premiums or collateral requirements. Scores below 650 make bonding difficult but not impossible through specialty programs.
