BOP Insurance: What a Business Owner's Policy Really Covers

Contractor Insurance: GL, Comp, Tools and Bonds in 2026

"Licensed and bonded" does not mean what your customer thinks it means

It is on the truck, the business card and the website of nearly every trades business in North America. Customers read it as this contractor is insured, so I'm protected and so is he.

Here is what a bond actually is. A surety bond is a three-party instrument between a surety, the contractor, and the project owner. If the contractor fails to perform, the surety steps in and makes sure the obligation is met. The Small Business Administration describes it plainly: surety bonds help small businesses win contracts by giving the customer a guarantee that the work will be done.

The customer. Not you.

And then the part almost nobody explains at the point of sale: when a surety pays out on your bond, you pay the surety back. A bond is not insurance you bought for yourself. It is credit extended on your behalf, backed by an indemnity agreement you signed, often personally.

That distinction — insurance transfers risk away from you, a bond transfers it through you — is the single most misunderstood thing in trades insurance, and it sets up everything else on this page. The wider program picture is in small business insurance.

1. Bonds vs insurance: the difference that costs money

1.1 The three parties

Insurance is two parties: you and the insurer. You pay a premium, the insurer accepts the risk, and when a covered claim happens the insurer pays and does not come looking for the money.

Surety is three parties: the principal (you), the obligee (the project owner or the licensing authority), and the surety. The bond guarantees your performance to the obligee. The surety is not pricing the likelihood that something goes wrong. It is underwriting the likelihood that you are good for it.

The common bonds in the trades:

Bond What it guarantees Who it protects
License or permit bond That you'll comply with the licensing statute or code The public and the licensing authority
Bid bond That if you win, you'll enter the contract at your bid The project owner
Performance bond That you'll complete the contract per its terms The project owner
Payment bond That you'll pay your subs and suppliers Subs, suppliers, and indirectly the owner

None of them protects you. All of them are required of you.

1.2 The indemnity agreement

This is the sentence to remember: a surety that pays a claim has a right of recovery against the principal. You signed a general indemnity agreement to get the bond, and on a small contracting business that agreement is usually personal, and often signed by a spouse as well.

So the sequence in a real failure is: you cannot complete the job, the owner calls the bond, the surety completes the job or pays damages, and then the surety bills you for what it spent. A bond does not make a failed project go away. It makes it someone else's problem for the duration of the project and yours again afterward.

Practical consequence: bonding capacity is underwritten on your financial statements, your working capital and your track record — not on your premium budget. If you want more bonding capacity next year, the levers are clean financials, retained earnings and a CPA-prepared statement, not shopping brokers.

1.3 The SBA guarantee program

If commercial sureties will not bond you, there is a federal route worth knowing about, and it is materially more generous than it was.

The SBA's Surety Bond Guarantee Program backs bid, performance, payment and ancillary bonds issued by participating sureties. As of the SBA's current guidance, the program covers contracts up to $9 million for non-federal contracts and up to $14 million for federal contracts — raised in March 2024 from $6.5 million and $10 million, the first increase since 2013. The SBA's guarantee to the surety runs in the range of 80% to 90% of the surety's loss.

The cost: 0.6% of the contract price as an SBA fee on performance and payment bond guarantees, returned if the bond is cancelled or not issued. There is no SBA fee on bid bond guarantees. You must qualify as small under SBA size standards and still meet the surety's credit, capacity and character requirements.

For a small or emerging contractor being turned down by the conventional market, this is the program that gets you onto bigger work.

2. Why the trades are priced in a different universe

2.1 What the fatality and injury data actually says

Contractors often assume their premiums are high because underwriters are pessimistic. The Bureau of Labor Statistics data says the underwriters are reading the same numbers you can.

From the BLS Census of Fatal Occupational Injuries for 2024:

  • 1,034 construction workers died on the job — roughly one in five of all US workplace deaths that year, against a national total of 5,070.
  • The construction fatality rate was 9.2 per 100,000 full-time equivalent workers, the lowest since 2011, but a figure that has sat between nine and ten for more than a decade.
  • Falls, slips and trips caused 389 of those deaths. Construction accounted for 48.8% of all fatal falls, slips and trips in private industry — nearly half of every fatal fall in the entire private economy, in one sector.

Non-fatal injuries follow the same shape. BLS reports that in private construction, falls, slips and trips resulting in at least one day away from work occurred at an annualized rate of 30.0 per 10,000 full-time workers in 2024, against 22.6 across all private industry. For falls to a lower level specifically: 13.9 in construction against 4.1 across private industry — more than three times the rate.

2.2 What that does to your rate

Those numbers arrive on your invoice through the class code. The Oregon Department of Consumer and Business Services publishes the only public interstate comparison of workers' compensation rates, using a fixed set of class codes. From its 2024 study, manual rates per $100 of payroll in the single most expensive state for each trade:

Class code Trade Highest state rate per $100 of payroll
5645 Carpentry — dwellings, three stories or under $38.79 (Georgia)
5551 Roofing, all kinds $28.84 (Georgia)
6217 Excavation and drivers $15.99 (New Jersey)
5183 Plumbing $7.68 (New York)
5190 Electrical wiring within buildings $5.96 (New York)
8810 Clerical office employees $0.48 (Hawaii), and $0.04 in Massachusetts and Washington

Read the top and bottom rows together. In a single sector, the spread between the office and the roof is a factor of hundreds. These are published manual rates before experience rating and carrier deviations, so they illustrate rather than quote — but the shape is why classification accuracy matters more in the trades than anywhere else in business insurance.

Practical consequence: if your estimator sits in an office four days a week and on site one day, that payroll split is worth real money — and it is only worth it if it is documented, accurate and defensible at audit. The full mechanics are in workers' compensation insurance.

3. The five policies a trades business actually needs

1. General liability, with completed operations.
Third-party bodily injury and property damage. The completed operations hazard is the part that matters most in construction: it responds to claims arising after you finished and left. Under the ISO business owner's policy, the products-completed operations aggregate is set at twice the per-occurrence limit and can be increased to three times by endorsement.

2. Workers' compensation.
In several US states the general employee threshold does not apply to construction — coverage is required from the first employee regardless. In Ontario, construction is on the mandatory list and the WSIB operates expanded compulsory coverage in the construction industry, which generally pulls in owners, partners and executive officers who would be exempt in any other sector.

3. Commercial auto.
Vans, trucks, trailers and the employee who runs to the supply house in her own car. Note that commercial auto is the one line still rising in a soft market: CIAB recorded a 4.5% average increase in Q2 2026 while overall premiums fell 2.0%. See commercial auto insurance.

4. Tools, equipment and installation coverage.
ISO publishes a Contractors' Installation, Tools and Equipment Coverage endorsement for the business owner's policy, providing installation coverage plus tools and equipment coverage, with optional extensions for non-owned tools and equipment and employees' tools. That second option is the one that resolves the argument after a break-in, when it turns out half the stolen tools belonged to the crew personally.

Note also what the Insurance Bureau of Canada says on the Canadian side: products, equipment or supplies stolen from or damaged in a vehicle are not covered under personal auto or home insurance. Tools in a van are a commercial exposure in both countries.

5. Builders risk, on the right projects.
Covers the structure under construction, materials and sometimes soft costs. Who buys it depends on the contract — sometimes the owner, sometimes the GC, sometimes you. The failure mode is everyone assuming someone else did. Settle it in writing at contract signature, not after the fire.

4. Subcontractors: the exposure that lands on you

4.1 In the United States

If a subcontractor cannot produce evidence of their own coverage, their payroll can be added to yours at audit, and their injured worker can become your claim. The mechanics vary by state, but the direction never does: uninsured subs become your exposure.

Two operational rules that prevent nearly all of this:

  • Collect the certificate before work starts, not with the invoice. A certificate obtained afterward may cover a period that did not include the loss.
  • Check the expiry date against your project schedule and re-collect on renewal. Certificates expire mid-project constantly.

4.2 In Canada: clearances

Ontario formalizes this and the consequence is unusually direct. Before you pay a subcontractor, obtain a WSIB clearance certificate. If you pay without one and the subcontractor has premium arrears, you can be required to pay those arrears yourself.

The WSIB also warns that the Canada Revenue Agency's contractor test and the WSIB's worker test are not the same test. Someone who is legitimately an independent contractor for tax purposes can still be your worker for coverage purposes. Do not rely on the tax classification.

4.3 The exclusion that removes their bad work from your policy

This one is technical and expensive. ISO publishes an endorsement titled Exclusion — Damage To Work Performed By Subcontractors On Your Behalf, which removes the exception that would otherwise bring subcontracted work back into coverage under the products-completed operations hazard. There is a designated-sites version too.

In plain terms: if that endorsement is on your policy, damage arising out of work your subs performed on your behalf may be excluded — on the very projects where you carry the contractual responsibility for it.

Ask your broker one question in writing: is any subcontractor work exclusion attached to my general liability, and if so, which projects does it apply to? Then read the answer next to your subcontract agreements.

5. The endorsements general contractors demand

The certificate a GC's compliance system accepts is not the same thing as the coverage. Certificates summarize; endorsements create. ISO publishes a long list of construction-specific ones, and these are the recurring asks:

Requirement The endorsement behind it What it does
Additional insured, ongoing operations Additional Insured — Owners, Lessees or Contractors, including automatic status when required in a written construction agreement Lets the GC or owner claim against your policy directly
Additional insured, completed operations Additional Insured — Owners, Lessees or Contractors — Completed Operations Extends that status to claims after the job is finished
Waiver of subrogation Waiver of Transfer of Rights of Recovery, including an automatic version tied to written contracts Your insurer gives up its right to recover from the GC
Primary and non-contributory Primary And Noncontributory — Other Insurance Condition Your policy pays first, before theirs
Per-project aggregate Designated Construction Project(s) General Aggregate Limit; Amendment of Aggregate Limits (Per Project) Stops one bad project from eating the aggregate you need for every other project that year

That last row is the one contractors most often do not know to ask for and most often need. Without a per-project aggregate, your $2M aggregate is shared across every job you run in the policy year. One serious claim in March can leave you contractually non-compliant in October.

6. When you outgrow the standard package

Contractors are eligible for the standard ISO business owner's policy, but inside a narrow box. The published conditions:

  • Annual payroll must not exceed $300,000
  • Exterior work may not be performed above three stories
  • Total cost of subcontracted work capped at 10% of annual gross sales
  • No renting or leasing equipment to others

Read the third condition again. A contractor who subcontracts 12% of turnover — an entirely normal way to run a small building business — is outside the standard form. So is one who grows past three or four employees on the tools.

Falling out of the box is not a problem. It is a transition to a separately underwritten commercial package policy, which costs more and negotiates better. The problem is falling out of it without knowing, and finding out at a non-renewal notice or, worse, at a claim. If your payroll, subcontracting share or work height changed this year, tell your broker before renewal.

7. What it costs

Commercial auto, contractors $172/month Progressive Commercial
Workers' compensation Priced per $100 of payroll by class code — see the trade table in section 2.2 Oregon DCBS (rates), institutional

The honest summary: for a trades business, workers' compensation and commercial auto are usually the two largest lines, and both are driven by things you control — classification accuracy, driver records, claim frequency — rather than by which carrier you pick.

One piece of timing. CIAB's Q2 2026 survey found construction risks among the ten lines whose premiums decreased, while commercial auto and umbrella rose. If your program renews as a package, the property and construction-risk components should be falling. Ask for the line-by-line breakdown rather than the total.

8. Nine questions before you bid

  1. What are my per-occurrence and aggregate limits, and do I have a per-project aggregate?
  2. Is completed operations included, and what is that aggregate?
  3. Is any subcontractor work exclusion attached to my general liability?
  4. Which additional insured endorsements are on the policy — ongoing operations only, or completed operations too?
  5. What class codes are my payroll split across, and can I defend the split at audit?
  6. Do I have tools and equipment coverage, and does it extend to employees' own tools?
  7. Who is buying builders risk on this project, and is that written into the contract?
  8. Do I have a current certificate — or in Ontario, a clearance — for every sub on site this week?
  9. What did I sign in the surety's indemnity agreement, and who else signed it?

Solo tradespeople with no employees have a different starting point: see insurance for sole proprietors and LLCs, including how to satisfy a client asking for proof of workers' compensation you are not required to carry.

9. Frequently asked questions

What insurance does a contractor need?

Five things in most cases: general liability with completed operations, workers' compensation, commercial auto, tools and equipment coverage, and builders risk on projects where the contract puts it on you. ISO publishes a Contractors' Installation, Tools and Equipment Coverage endorsement for the business owner's policy, with optional extensions for non-owned tools and for employees' own tools. Which limits you need is usually set by your client contracts rather than by your own risk assessment.

What does "licensed and bonded" actually mean?

That the contractor holds the required trade licence and has a surety bond in place. The bond is a three-party instrument between the surety, the contractor and the obligee, and the SBA describes surety bonds as giving the customer a guarantee that the work will be done. It protects the customer, not the contractor — and if the surety pays a claim, it has a right of recovery against the contractor under the indemnity agreement the contractor signed. Being bonded is not the same as being insured.

Is a surety bond the same as insurance?

No. Insurance is a two-party contract in which the insurer accepts a risk and does not seek repayment after paying a covered claim. A surety bond is a three-party guarantee in which the surety pays the obligee and then recovers from the contractor. Practically, insurance transfers risk away from you and a bond routes it through you.

Do I need workers' comp for a construction business with one employee?

In several US states, yes — construction is carved out of the general employee threshold, so coverage is required from the first employee regardless of the count that applies to other industries. In Ontario, construction is on the WSIB's mandatory registration list and the board operates expanded compulsory coverage in construction, which generally covers owners, partners and executive officers who would be exempt in other sectors. Confirm with your state agency or provincial board.

Am I responsible if my subcontractor has no insurance?

Frequently, yes. In the US, an uninsured subcontractor's payroll can be added to yours at workers' compensation audit and their injured worker can become your claim. In Ontario the rule is explicit: obtain a WSIB clearance certificate before paying a subcontractor, because if you pay without one and the sub has arrears, you can be required to pay those arrears yourself. The WSIB also notes that the CRA's contractor test and its own worker test are different tests.

What is a per-project aggregate and why does it matter?

A standard general liability aggregate applies across everything you do in the policy year. A designated construction project aggregate, available by ISO endorsement, gives each project its own aggregate limit. Without it, one serious claim early in the year can exhaust the aggregate your later contracts require you to carry, leaving you contractually non-compliant on jobs you have already signed.

How much does contractor insurance cost?

There is no meaningful single figure, because workers' compensation dominates the program and is priced per $100 of payroll by class code. The Oregon DCBS interstate study shows the scale: in its 2024 data, carpentry on dwellings was rated as high as $38.79 per $100 of payroll and roofing as high as $28.84, against $0.04 to $0.48 for clerical office work. On the liability side, commercial publishers put general liability for construction and contracting near the top of the industry range at roughly $337 a month, against a $45 median across all industries.

Can a contractor get a business owner's policy?

Yes, within limits. Under ISO's rules, contractors are eligible for the standard BOP only if annual payroll does not exceed $300,000, exterior work is not performed above three stories, subcontracted work does not exceed 10% of annual gross sales, and the business does not rent or lease equipment to others. Growing past any of those moves you to a separately underwritten commercial package policy — which is normal, and usually gives you more negotiating room, provided you find out before your renewal rather than after a claim.
