Illinois Statutes Chapter 50. Local Government § 830/20. Unified license and permit bond

(a) A contractor seeking to do work or doing work in a county or municipality may obtain a unified license and permit bond. This unified license and permit bond may be used by the contractor, at the contractor's discretion, instead of any other license or permit bond, or both, required of a contractor by the county or a municipality within that county. The bond shall be in the amount of at least $50,000 for counties included within the provisions of the Northeastern Illinois Planning Act (now repealed)  1 and in the amount of at least $25,000 for all other counties.

(b) The unified license and permit bond shall be held for compliance with the ordinances and regulations governing contractors in the county or any municipality within that county where the contractor seeks to do work or is doing work. The unified bond required by this Act shall be filed by the contractor with the county clerk. At the time of filing, the county clerk may charge a reasonable administration fee, determined by the county board or board of county commissioners.

(c) If a contractor elects to use a unified license and permit bond under this Act and the territory of a municipality where a contractor seeks to do or is doing work is included within more than one county, then the contractor shall obtain a unified license and permit bond from each county and shall file a unified bond with each of the respective county clerks whether or not the contractor seeks to do or is doing work in that part of the municipality included in only one of the counties.

In addition, the contractor shall file a certified copy of the unified bond with the clerk in the municipality within that county where the contractor seeks to do work or is doing work. At the time of the filing, the clerk may charge a reasonable administration fee, determined by the corporate authorities of the municipality.
