What it is and who needs it.
What the bond actually guarantees
Cook County's Department of Building and Zoning requires every contractor performing work in unincorporated Cook County — the townships and areas outside any incorporated city or village — to register, and registration is conditioned on a $20,000 surety bond filed with the Department. The County charges a $150 initial fee per trade and a $75 annual renewal fee per trade directly, separate from the bond premium.
It's a three-party arrangement: you (the principal), the surety carrier, and Cook County (the obligee), with property owners and the County as the protected parties. If a bonded contractor's work causes damage the registration requirement is meant to guard against, a harmed party can recover against the bond up to the $20,000 penal sum.
It is not insurance for you — if the surety pays a claim, you repay the surety. Registration renews annually by December 31, so line your bond term up with that date to avoid a gap that would keep you off the County's registered-contractors list.

Claims, renewal, filing, and what sets the price.
If a claim is made
A claim comes from the party the bond protects, the obligee named on the form, when the duty the bond guarantees is not met.
The surety investigates and pays a valid claim, up to the $20,000 bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.
Renewal and term
The premium covers a one-year term from the effective date you choose; a longer term is the same price per year, chosen at checkout.
Renew before the expiry date to keep the bond in force: the license, permit or contract it backs expects continuous coverage.
How to file it

What sets the price
The premium is fixed at $100 at the $20,000 amount for every applicant: the carrier’s rate book prices this bond by the form, not by your credit or your business profile.
