When a local government approves your site plan or subdivision — roads, curbs, drainage, sidewalks, utility stubs — it typically will not sign off until you’ve guaranteed those improvements actually get built. A site improvement bond is that guarantee, filed with whichever city, county, or planning authority approved your project. Premium is priced at 3% of the bond amount plus a $25 underwriting fee, $275 minimum — enter the improvement cost your approving authority requires and your exact price appears at the application.
















Site improvement bonds close fast once your approving authority’s figure is in hand. Here is the whole thing:
Who is requiring the bond (the city, county, or authority name), the estimated improvement cost, your estimated completion date, and the type of work being bonded. Because underwriting on a site improvement bond is more involved, every request carries a $25 fee.
Most requests at routine amounts clear the same day the file is complete. A soft credit pull runs as part of underwriting and never affects your score; larger or unusual improvement scopes can take a brief additional review.
Submit the executed bond, on whatever form your city, county, or planning authority requires, to satisfy the condition attached to your site plan approval. Wet-ink original mailed on request.
A site improvement bond — also called a subdivision bond, site plan bond, or public improvement bond depending on the jurisdiction — is a developer’s guarantee to the government that approved the project: the roads, curbs, sidewalks, drainage, and utility work shown on the approved site plan will actually get built, or the local government has the money to finish them. It is standard practice across nearly every U.S. municipality and county with a site plan or subdivision review process, though each jurisdiction sets its own form, amount, and release conditions.
It is the usual three-party arrangement: you (the principal, typically the developer), the surety carrier, and your local government as obligee — the city, county, or planning authority that conditioned final approval on the bond. If the improvements are not completed to the approved plan, the obligee can draw on the bond to hire another contractor to finish them. It is not insurance for you — if the surety pays a claim, you repay the surety.
Because no single statute governs this bond nationwide, we do not cite one — the requirement comes from whatever ordinance, subdivision regulation, or development agreement your local approving authority applies, and the amount is normally the engineer’s estimated cost of the improvements, sometimes with a contingency percentage the authority adds. Name the authority requiring your bond in the application, and put the improvement cost from your approved plans in the amount field — we price from that figure, with a $25 underwriting fee that applies to every site improvement request on this program.
These are the actual issuing fields — who is requiring the bond, your estimated improvement cost, and the type of work being bonded. A $25 underwriting fee applies to every request; the rest is priced from your figure.
