General Contractor Insurance Requirements by State (2026): All 50 States

A fire on a half-framed house does not care that your CGL declaration looks expensive. A hurt carpenter does not care that your LLC is “protected.” A developer’s insurance exhibit does not care that your state only asked for a $25k bond.

That’s why general contractor insurance searches crush every other contractor insurance topic — and why the companion to our GC license map has to be an honest insurance map, not a sales page pretending $1M/$2M is federal law.

Here’s the contrast with trade insurance posts (garage door, locksmith, pest, mobile mechanic): more states publish real GC / HIC / registration floors and bonds — Florida CILB, California CSLB, Maryland MHIC, New Jersey HIC, Washington L&I, Arizona ROC, Nevada NSCB, Oregon CCB. Still: those floors are usually below what commercial owners type into the exhibit. Builder’s risk, umbrella, completed ops, and sub COI verification are where GCs actually get hurt.

This guide is the 2026 map — board floors where we pulled primary sources, soft language where the data is thin, and the COI reality that shows up on real jobs. Sister post for the license card itself: General Contractor License Requirements by State (2026).

What insurance general contractors actually buy

You are not buying “GC insurance” as one SKU. You are buying a stack that covers third-party claims, the unfinished structure, the trucks, your people, excess limits, and — when you touch design — professional mistakes.

Line	What it covers	Typical ask	Legal status
Commercial General Liability (CGL)	Third-party bodily injury & property damage; products/completed operations; personal/advertising injury (form-dependent)	$1M / $2M on most commercial COIs; sometimes per-project aggregates	Industry practice / contract. Some boards set lower license floors (FL GC $300k/$50k; CT HIC $20k; WA registration floors; MD/NJ HIC ~$500k).
Builder’s Risk	First-party property: the structure under construction, materials, sometimes soft costs / delay	Full project value; deductibles and sublimits matter	Contract-driven — owner or GC purchases per prime contract. Not a substitute for CGL. Not tools coverage.
Commercial Auto	Liability (and usually physical damage) for work trucks, pickups, equipment haulers	Often $1M CSL on commercial exhibits; hired/non-owned if staff drive personal vehicles	State FR law sets floors for all drivers. Personal auto usually excludes business use.
Workers’ Compensation	Employee injuries on site; employers’ liability for related suits	Statutory + EL often $100k/$500k/$100k on COIs	State law once employee threshold is met. Construction is often stricter. Texas optional for most private employers (nonsubscribers) with traps; public jobs via §406.096.
Umbrella / Excess	Limits above GL + auto (+ sometimes employers’ liability)	$2M–$5M common on larger commercial / institutional projects	Optional unless contract requires. Follow-form vs drop-down wording matters.
Professional Liability / E&O	Design errors, negligent professional services, design-build exposure	Often $1M+; project-specific sometimes required	Contract / risk-driven. Design-build nearly always; pure construction GCs still get surprised by design-assist creep.
Surety / License Bond	Consumer / board protection under bond terms (not liability insurance)	$1k–$500k+ depending on board (CA $25k; NV schedule; AZ ROC; OR CCB)	Where the licensing board requires. Bond ≠ GL ≠ builder’s risk.
Inland Marine / Tools & Equipment	Contractor tools, leased equipment, installation floaters	Scheduled limits	Optional but strongly recommended — builder’s risk is not your toolbox.

Builder’s risk — the structure is not on your GL

This is the GC signature myth. Commercial general liability does not insure the building while it is under construction. CGL responds to claims by others for injury or damage you cause. When a windstorm guts an open frame, or a fire takes the nearly finished roof, or materials are stolen from the site overnight, you are in builder’s risk territory — a first-party property form written on the project.

• Who buys it: the prime contract decides. Owners/developers often purchase on commercial ground-up; GCs sometimes buy on design-build or when the exhibit assigns it. Subs rarely insure the whole project.
• Who must be listed: named insureds, additional insureds, and loss payees (lenders) — get this wrong and claim checks stall.
• Watch-outs: existing structures on renovations, owner-furnished equipment, off-site storage, transit, soft costs / delay in completion, flood and earthquake sublimits, occupancy / hot-testing, and the definition of project completion.
• Not covered by BR: your tools and mobile equipment (inland marine), third-party liability (CGL), employee injuries (WC), or design errors (E&O).

Mythbusts GCs still believe

1. “My GL covers the building while it’s under construction.” No — that’s builder’s risk (first-party). GL is third-party liability.
2. “I’m a sole proprietor, so I don’t need workers’ comp.” Depends on state law and every client contract. Construction thresholds are often 1+. Texas nonsubscriber opt-out exists with notice traps; public jobs and serious GCs still demand WC.
3. “My sub’s insurance covers their work.” Not if they are uninsured, underinsured, misclassified, or never issued the AI / completed-ops endorsements. Verify COIs; audit high-risk trades.
4. “One policy covers everything.” No GC practice policy replaces builder’s risk + auto + WC + umbrella + E&O when those exposures exist.
5. “The COI is the coverage.” A certificate is evidence, not the policy. Additional insured status needs endorsements. Cancelled policies + stale PDFs = you are exposed. Same consumer logic as NAIC contractor scam guidance: verify with the insurer.
6. “Bonded means insured.” Bonds and insurance are different animals. A CSLB / ROC / NSCB / CCB bond protects under bond terms up to the penal sum and can chase you for reimbursement. It does not defend a third-party BI claim the way CGL does.
7. “The homeowner’s policy has me covered on residential jobs.” Homeowners policies are for the residence owner — not your business liability, not your employees, and often contested when a contractor causes the loss. Carry your own CGL; do not borrow the HO-3 as a business plan.
8. “Completed ops ended when I got paid.” Products/completed operations is exactly why doors fail, roofs leak, and decks collapse months later. Upstream parties demand completed-ops AI for a reason — match CG 20 10 + CG 20 37 (or equivalents) to the exhibit.
9. “Per-occurrence limits are all that matter.” Aggregates and per-project aggregates matter on multi-site years. An exhausted aggregate mid-project is a crisis.
10. “Design-assist isn’t design.” If you stamp, hire under your contract, or take responsibility for constructability decisions that are really design, E&O exposure is in the room. Name it and insure it.

COI checklist when you hire subs (and when owners hire you)

Treat every subcontract like a mini insurance program. Before a sub mobilizes:

• Limits: CGL at least matching your contract flow-down (often $1M/$2M); WC statutory; commercial auto if they drive on site; umbrella if required.
• Additional insured: ongoing operations and completed operations (CG 20 10 + CG 20 37 or equivalents) naming the upstream parties required by the prime.
• Primary & noncontributory: their policy responds first without contribution from your program.
• Waiver of subrogation: in favor of owner / GC / required parties where permitted.
• Certificate holder: exact legal names; current dates; no pending cancellation without notice language your exhibit requires.
• Verify: call the agent or carrier on high-risk trades. A pretty ACORD 25 is not a warranty.
• Wrap-ups: if the job is OCIP/CCIP, follow enrollment and payroll reporting — and keep practice coverage for exclusions (auto, E&O, off-site, corporate).

When you are the one sending a COI upstream, match the exhibit — do not send a generic certificate and hope. Per-project vs aggregate wording, AI for completed ops, and umbrella attachment points are where bids die in procurement review.

OCIP / CCIP wrap-ups — brief and honest

OCIP (owner-controlled) and CCIP (contractor-controlled) programs centralize certain project coverages — typically GL and often WC — for enrolled parties. They are not magic:

• Enrollment, payroll reporting, and safety duties are real administrative work.
• Auto, professional liability, pollution, off-site fabrication, warranty work, and corporate operations frequently sit outside the wrap.
• Bid credits and audit true-ups can surprise unpaid estimators.
• Builder’s risk may be bundled or separate — read the manual.
• In monopolistic WC states, wrap design changes because WC may already be state-fund only.

High-stakes deep dives

Florida — CILB $300k/$50k (license floor, not commercial COI)

Rule 61G4-15.003: general and building contractors must maintain $300,000 public liability and $50,000 property damage for an active certificate/registration. Many other CILB categories sit at $100k/$25k. DBPR can audit. Construction WC generally at 1+. Commercial owners still want $1M/$2M + umbrella. Sources: 61G4-15.003, DBPR Construction FAQs.

California — $25k bond + LLC GL + WC discipline

CSLB active licenses require a $25,000 contractor bond (B&P §7071.6). LLCs need CGL with at least a $1 million aggregate under B&P §7071.19 (plus add-ons per personnel of record). CGL is not a universal mandate for every entity type — homeowners still expect disclosure of whether you carry it. WC with employees; confirm current CSLB WC-on-file rules. Sources: CSLB Bond Requirements, CSLB Law Book materials on CGL/LLC.

Texas — nonsubscriber trap + §406.096 public projects

Most private employers may operate as nonsubscribers (Labor Code §406.002) with posting, written employee notice, and DWC filings (including annual windows). You lose exclusive remedy and key defenses if a worker sues. Governmental building/construction contracts require WC certification under §406.096 with sub flow-down. Private commercial work still demands WC by contract almost everywhere. Source: TDI nonsubscribers.

Maryland & New Jersey — HIC ~$500k floors

MHIC and NJ HIC regimes commonly require liability around $500,000 — closer to market practice than most license floors. Still raise limits and add umbrella for institutional / multi-family work. Confirm live MHIC and NJ DCA pages before locking a binder number.

Washington, Arizona, Nevada, Oregon — registration/license bonds

WA L&I: contractor registration insurance floors commonly $200k/$50k or $250k CSL plus a registration bond. AZ ROC: bond scales with class/volume. NV NSCB: bond $1k–$500k set by the Board. OR CCB: bond by endorsement. None of these replace CGL, builder’s risk, or WC.

Connecticut — HIC $20k floor

DCP Home Improvement / New Home Construction registrations list GL of at least $20,000 — a floor, not a commercial program. Raise to market $1M/$2M.

All 50 states + DC

Tags: req = clear contractor-board GL floor, registration insurance floor, or high-signal bond/WC rule called out with primary or strong secondary sources; local = city/county or soft-confirm dollars; no = rare for GCs (most states have some contractor overlay — we used local when the statewide GL dollar was soft).

Market note for every state: owners and upstream GCs commonly still ask $1M/$2M CGL + WC + auto + AI/completed ops even when the license floor is lower or silent. Builder’s risk is almost always contract-specified.

FAQ

Bottom line

Insurance for general contractors is a stack — CGL + builder’s risk + commercial auto + WC law + umbrella on larger jobs + E&O when design enters the chat — plus whatever license bond your board demands. Florida’s $300k/$50k CILB floor, California’s $25k bond and LLC GL rules, Maryland/New Jersey ~$500k HIC floors, Washington L&I registration insurance, Arizona/Nevada/Oregon bond schedules, and Texas nonsubscriber + §406.096 public-project rules are the headline calls. Everywhere else: confirm the board packet, confirm who buys builder’s risk, verify sub COIs for real, and assume the market still wants $1M/$2M with completed ops.
