FAQ
Common questions.
Who needs an Illinois Subdivision Bond?
Real estate developers, subdividers, and builders who are creating new subdivisions in Illinois need this bond. It's required by the local city, village, or county government before they will approve your final subdivision plat, allow you to sell lots, or permit home construction. The bond ensures you complete all public improvements like streets, sidewalks, utilities, and drainage systems according to approved plans.
How much does an Illinois Subdivision Bond cost?
The bond amount is based on an engineer's cost estimate of the public improvements you must complete—typically 100% to 150% of the estimated cost for streets, utilities, sidewalks, and drainage. For example, if improvements are estimated at $400,000, your bond penalty might be $500,000. The premium you pay depends on your credit, financial strength, and experience—typically 1-5% of the bond amount for qualified developers. You can reduce upfront costs by phasing the bond (bonding each construction stage separately).
When is the Illinois Subdivision Bond released?
The bond remains in force until you complete all required public improvements according to approved plans and the municipality or county formally accepts the work. After final inspections verify everything is built correctly, you request a bond release from the local government. Some municipalities require notarized original bond documents for recordation. The timeline typically ranges from 1 to 3 years depending on project size, though extensions are available if construction takes longer than planned.
