Subdivision Bond Cost

Subdivision bonds, also called site improvement or plat bonds, guarantee that a developer will complete the public improvements a city or county requires before it accepts a new subdivision.

How much does a subdivision bond cost?

Bond amount is set by the local government, usually the engineer's estimate of the remaining improvement cost. Premium runs 1 to 3 percent of the bond amount for well-qualified developers. Term runs until the work is accepted. Premium for a subdivision runs about 1% to 15% of the bond amount per year, set by underwriting based on credit and financials.
