Subdivision Bonds
Subdivision and site-improvement bonds guarantee the public improvements you've promised the municipality — roads, grading, water, sewer, and more. We know how these are structured and reduced.

A subdivision bond (also called a site-improvement, plat, or completion bond) guarantees a municipality that a developer will build the public improvements required for approval — streets, curbs, sidewalks, storm drainage, water and sewer lines, grading, and landscaping.
Unlike contract bonds, the obligee is the local government, and there's no payment to a contractor behind the bond — so these are underwritten on the developer's balance sheet and the cost of the improvements. We help structure the bond so it can be reduced or released as work is accepted.

Subdivision Bonds FAQ
What is a plat bond?
A plat bond is a type of subdivision bond that guarantees the public improvements tied to a recorded plat — roads, curbs, drainage, water, and sewer — will be completed on schedule. "Plat bond," "site-improvement bond," and "completion bond" are regional names for the same guarantee a developer makes to the municipality.
How much does a subdivision bond cost?
A subdivision bond typically costs about 1%–3% of the bonded cost of the improvements per year, driven by the developer's financial strength. On $1,000,000 of improvements that's roughly $10,000–$30,000. Because there's no contractor behind the bond, the rate rests on the developer's balance sheet — we quote your exact rate after a quick review.
How is the subdivision bond amount determined?
By the engineer's estimate of the public improvements — often set by the municipality at 100–125% of that cost. We bond the exact penal sum the ordinance or agreement requires.
Do subdivision bonds require underwriting?
Yes. Because there's no contractor liable behind the bond, the surety underwrites the developer's financial strength and the cost to complete. Stronger financials mean easier approval and better terms.
Can the bond be reduced as work is completed?
Usually. Most municipalities allow phased reductions as improvements are inspected and accepted, with a maintenance bond held at the end. We help you document and request those reductions.
