Cook County septic bonds.

Installing a private sewage disposal system — a septic system — in unincorporated Cook County requires review by the Cook County Department of Public Health and a permit from the Department of Building and Zoning, which conditions the permit on a $10,000 surety bond. Premiums cost 0.5% of the bond amount, $100 minimum. The application collects no credit information.

What it is and who needs it.
What the private sewage disposal bond actually guarantees
Outside the four incorporated Cook County municipalities that run their own state-approved septic ordinances (Barrington Hills, Inverness, Palos Park, and South Barrington), the Cook County Department of Public Health reviews and approves private sewage disposal (septic) system applications — plans, soil reports, and the property's legal description — under standards set by the Illinois Department of Public Health, the state's governing body for septic systems.
The Department of Building and Zoning issues the permit that lets you install the system, and conditions it on a surety bond. It is a three-party arrangement: you (the principal), the surety carrier, and Cook County (the obligee), protecting the County and neighboring property owners if the installation is not completed to the approved plan.
Cook County's published Building and Zoning bond schedule sets this bond at $10,000. The premium is 0.5% of that amount, $100 minimum, and the application collects no credit information.
