What bonding costs by trade in Illinois

Bond cost is a percentage of a number the state sets

Two numbers set the bill: the bond amount, fixed by the agency that registers the trade, and the rate, a percentage a bond company prices from your credit and record.

Illinois bond rates typically run 1% to 4% of the bond amount with strong credit, and 5% to 15% with weaker credit. The trade's role in the price is only the first number. A $20,000 plumbing bond at those published rates is roughly $200 to $800 a year with strong credit, or $1,000 to $3,000 without it.

That makes the trade the floor and the credit tier the range. The floor differs by a factor of two and a half between Illinois trades; the range differs by a factor of fifteen. If you want to move the bill, the percentage is the half that moves. The lower premium guide is the how-to.

The premium table by trade

Here is the whole state picture in one table. The premium columns are the published Illinois rate ranges multiplied by each bond amount — the arithmetic of the two claims this page cites, not separate quotes.

Read your row, then remember the rate column is the half you control. Every bond in the table runs on its agency's own form, so the paper is fixed and the premium is not.

Plumbing and irrigation: the two $20,000 bonds

The two water trades post identical bonds through the same agency, with different registrations behind them.

The plumbing registration is $150 a year, renewable with a $100 late or reinstatement fee, and the bond rides on the Department's own form, expiring September 30 each year. The irrigation bond is also $20,000, on its own form, for anyone installing lawn sprinkler systems.

The premium arithmetic is the same for both at every credit tier, which is why the table shows one row's numbers twice. What differs is the paperwork behind the bond: plumbing adds an insurance certificate with four state-set limits, irrigation adds the irrigation contractor registration. The plumbing side is mapped in full on the plumber bond page.

Roofing: one trade, two bond sizes

Roofing is the one Illinois trade where the contractor chooses the bond amount, by choosing the license tier.

The limited roofing license covers residential work only and carries a $10,000 bond. The unlimited license covers residential and commercial work and carries $25,000. The application fee is $125 either way, and the license runs to December 31 of each odd-numbered year, so the fee is paid in alternate years.

For a self-employed residential roofer, the cheaper tier is also the honest one: buying the unlimited bond to look bigger costs premium on $15,000 that no residential job ever called for. The full license walk-through, including the exam behind it, is the roofer license page.

The trade that pays insurance instead

One Illinois trade can pay the financial-responsibility demand with a policy instead of a bond, and the comparison is worth having in a budget.

A commercial pesticide applicator pays $300 for a three-year license and shows financial responsibility through a surety bond or a certificate of liability insurance with published minimums. An irrigation-and-spray lawn operator usually meets it with the policy the license renews alongside, not with a second premium.

The insurance route's minimums are real money on paper — $50,000 per person and $100,000 per occurrence bodily injury with a $500,000 aggregate — but general liability policies at or above those limits are what most operators carry anyway. The stack for this trade is set out on the get bonded and insured guide.

The trades that pay nothing to the state

Cleaners, painters, handymen and most remodelers pay no bond, no license fee and no registration to any Illinois state agency. The budget line for bonding in those trades is zero, and the request that does arrive is a certificate.

What those trades buy is optional and demand-driven. A dishonesty bond for a cleaner is a real product sold to real buyers — property managers ask for it, and some clients read it as the price of entry. But it is priced as an insurance product against employee theft, not as a state bond, and it is not on any Illinois form.

When a client in an unlicensed trade asks for "bonded and insured," the useful answer is a certificate of insurance at the limits in the contract, and a clear sentence about what a dishonesty bond would and would not cover. The mechanics of the certificate are on the certificate of insurance guide, and the bond versus insurance page has the wording for the sentence.

Keep the percentage down, not just the amount

The trade sets the bond and the credit sets the rate, so the budget's real lever is the half you own. Work it before the renewal, not after the quote.

The published tiers put excellent credit at 650 and above, average at 550 to 649, below average at 549 and under. A contractor sitting at 640 is one balance away from a different price list, and the same file also decides what a paid bond claim costs next year.

Two pages take it from here. How to pay less for a bond is the credit-and-shopping how-to. How a claim hits your bond is the record worth protecting, because a claim moves the rate more than any tier does.
