Illinois Subdivision Bond Requirements
How subdivision (site improvement / plat) bonds work in Illinois: the enabling statute local governments rely on, how the bond amount is sized from the engineer's estimate, and what developers post to get a plat approved.
Application process
The bond is posted with the city or county that approves the plat, not a state agency. The local government (the obligee) sizes the security from the project engineer's estimate of the improvements still to be built (streets, curbs, sidewalks, storm drains, water and sewer), and the developer files the executed bond with the development or subdivision improvement agreement. Many Illinois jurisdictions reduce the required amount as phases are inspected and accepted.
Renewals
The bond stays in force until the local government inspects and accepts the improvements and releases the security; it is not renewed on a fixed license cycle.
Amounts are set locally under 65 ILCS 5/11-12-8, so two projects in different Illinois jurisdictions can face different security terms for the same scope of work. Confirm the exact security form and amount with the approving city or county before ordering the bond.
Key statutes
- Municipal plat approval, completion guarantee (65 ILCS 5/11-12-8) . Municipal code provision under which Illinois municipalities require a bond or letter of credit guaranteeing completion of subdivision improvements before plat approval.
