How to get bonded and insured in Illinois

The order that keeps a self-employed contractor working

Register first, bond second, insure third. Every Illinois trade that demands a bond hangs it on a registration, and the registration names the insurance limits.

That order is not taste. A plumbing contractor cannot buy the right bond before registering, because the Illinois Department of Public Health sets the bond amount, prints its own bond form, and requires the business name on the bond to match the application. Work backwards and you buy the wrong paper twice.

Which trade you work decides most of this. See when Illinois requires a bond for the trade-by-trade list, and what bonding costs by trade for the premium side of it.

Find out who registers your trade

Illinois has no single contractor license. Each trade answers to a different body, and some answer to nobody at the state level at all.

Plumbers and irrigation contractors register with the Illinois Department of Public Health. Roofers license with the Illinois Department of Financial and Professional Regulation. Commercial pesticide applicators, which is most lawn-care operators who spray, license with the Illinois Department of Agriculture. Cleaners, painters and most remodelers answer to no state board — but a city can still demand papers before a permit.

Cities add their own layer. Elgin requires a $20,000 permit bond from sewer and mechanical contractors before it issues permits. Naperville requires electrical contractors to register with the city and pulls no punches on the point: all electrical work in the city requires a permit.

Start on the trade-by-trade requirements page. It lists who requires what, with the bond amount each body sets.

Buy the surety bond on the agency's own form

The bond amount is not your choice, and neither is the paper it sits on. Illinois agencies print their own bond forms and refuse substitutes.

The plumbing bond is the clearest example. It is $20,000, it runs on the Department's own form, it expires September 30 of the current year, and the Department refuses continuous bonds. A letter of credit in the same amount is accepted instead. The roofing license bond is different again: $10,000 for a residential-only license, $25,000 for one that covers commercial work too, and this one is continuous.

One bond house can write all of these. The premium is where shopping helps, and how to pay less for a bond covers that in full.

Buy the policies the paperwork names

The registration sets your insurance limits before any client does. Buy to the registration first, then add what clients ask for.

The plumbing registration demands a certificate of insurance showing $100,000 general liability per occurrence, $300,000 bodily injury, $50,000 property damage, and $500,000 workers' compensation if you have employees. The roofing license asks for $500,000 liability per occurrence of personal injury and $250,000 property damage, on the Department's own RF-INS form. The pesticide applicator license takes either a bond or a certificate of liability insurance, and names its own minimums.

A client can ask for more than the state does, but never for less. What a bond pays and what a policy pays are different things, and mixing them up is expensive — the bond versus insurance page separates them.

Workers' comp when you work alone

Working alone, you are usually outside the workers' compensation requirement. The paperwork still asks, so answer it with the right form rather than with silence.

A plumbing contractor with no employees files a notarized Affidavit of No Employees with the state. A corporation, partnership or LLC whose only people are its officers, partners or members files the opt-out form, where each person rejects benefits under the Illinois Workers' Compensation Act. The event vendor version of the same rule is plainer still: proof of workers' comp is only needed if you employ help.

The details, including what changes the day you hire someone, are on the workers' comp exemption page.

The certificate the client will actually check

The certificate of insurance is the document your client holds. Get its details right or the job stalls at the front desk.

Illinois agencies are pickier than most clients. The plumbing registration wants the certificate to name the Department itself as certificate holder, refuses binders and continuous certificates, and demands written notice 30 days before any cancellation or expiry. The State Fair's vendor certificate names its own extra condition: the Illinois Department of Agriculture must appear as additional insured, and certificates without that wording are not accepted.

The full walkthrough, including what a client means by "make us additional insured", is the certificate of insurance guide.

The calendar you now own

A bond is not a purchase, it is a subscription. Write every expiry down in one place the day you register.

The plumbing contractor registration expires September 30 of the current year, which is why its bond may not be continuous. The roofing license runs to December 31 of each odd-numbered year regardless of when it was issued. Surety bonds themselves typically run one-year terms, so even a continuous roofing bond gets looked at once a year by the surety that wrote it.

Miss a date and the consequence is administrative, not negotiable: a plumbing registration is suspended if a renewed certificate is not on file before the old one expires, and suspended registration stops your apprentices counting time.

What the first year costs

Budget three numbers: the registration fee, the bond premium, and the policy. Two of the three are published; the third is a quote.

Registration fees are published. Plumbing registration is $150 a year. The roofing license application is $125. The commercial pesticide applicator license is $300 for three years. Bond premiums are published as ranges: an Illinois bond typically costs 1% to 4% of the bond amount with good credit, so a $20,000 bond runs roughly $200 to $800 for the year. General liability is quoted, but starting prices are published: one direct carrier starts at $19 a month, another at $27.50.

The full premium breakdown by trade, credit tier and bond amount is on the bonding costs page, and the vendors compared side by side are on the insurance providers page.

Take the first job with the paperwork in your truck

Once the registration, bond and certificate are on file, you are set up the way Illinois trade paper expects. Keep copies where the work happens, because permits and clients ask at the site, not by email.

Expect the certificate to be requested before the bond is, and the bond to be requested before anyone reads your registration number. Commissary kitchens, village permit counters and event offices all want the same document with a different holder typed on it.

One last thing before you sign the first contract: know what a claim on your bond would mean. It is the one part of this stack that protects the client and comes back to you. The bond claim guide covers what happens, and how to keep a dispute from turning into one.
