Before Cook County's Department of Building and Zoning will issue a permit to place a temporary construction trailer on an unincorporated-area site, it requires the applicant to post a $10,000 surety bond to the Board of Commissioners of Cook County. Ours is $100 flat — the price you see is the checkout price. The bond issues the moment you pay — a soft credit pull at most, never a hard inquiry.
















A temporary-trailer restoration bond is a small, specific filing. Here's the entire process:
The trailer's location, township, and intended use, plus your business details. That's the application.
Restoration bonds like this are among the thousands of bond types that issue right after purchase. At most, 1–2 business days.
Your executed bond arrives by email, ready to file with the Cook County Department of Building and Zoning alongside your trailer permit application. Wet-ink original mailed on request.
Cook County's own restoration-performance bond form, issued by the Department of Building and Zoning, conditions a temporary-trailer permit on a $10,000 guarantee that if the associated construction project is delayed past its permit or abandoned before the building is completed, the trailer is removed and the site is returned to the condition it was in before the trailer went in.
It's a three-party arrangement: you (the principal), the surety carrier, and the Board of Commissioners of Cook County (the obligee), with the County itself as the party the bond protects. If the trailer is left in place and the site is not restored, the County can draw against the bond up to the $10,000 penal sum to cover the cleanup.
It is not insurance for you — if the surety pays a claim, you repay the surety. The obligation runs for as long as the trailer permit is open; the County's own form ties release to the Building Commissioner confirming the site has been restored, not to a fixed calendar date, so keep your paperwork until you get that release.
These are the actual issuing fields — the site location, the trailer's intended use, and your business details.
