About this bond

What a subdivision bond is

Cities and counties often require a developer to bond the public improvements in a new subdivision or site plan, like streets, sidewalks, storm drains, sewer and water lines, before they approve the final map or permits. The bond guarantees the improvements are built to the agency's standards.

In Illinois

Illinois municipalities approve subdivision plats under 65 ILCS 5/11-12-8, which covers plat approval and bonds for improvements. Each city or county sets the bond amount in its own ordinance.

  • State law bars a county or municipality from requiring a cash bond when an irrevocable letter of credit is filed.

You need this bond if you're

  • A developer or subdivider recording a final map
  • A builder with a site plan that includes public improvements
  • A contractor building improvements under a developer agreement
  • An owner required to bond grading or erosion control

What the surety looks at

The project, the engineer's cost estimate for the improvements and the developer's finances. Larger projects need financial statements.

3% of the contract amount, with a $250 minimum. The calculator on this page works it out for your amount. Propeller adds a $25 service fee for this bond.

No. You pay the premium. The bond amount is the most the surety would pay out on a valid claim, and if it ever pays one, you pay the surety back.

Who sets the subdivision bond amount in Illinois?

The city or county approving the subdivision, usually based on the engineer's estimate of the improvement costs. See the facts above for the state law behind it.
