A subdivision bond, also known as a plat bond or site improvement bond, guarantees that a developer will complete the public improvements required as part of a private development. These improvements usually include roads, sidewalks, curbs, gutters, drainage systems, water and sewer lines, and street lighting.
Cities, counties, and municipalities across the U.S. require subdivision bonds before approving plats or issuing development permits. The bond means public infrastructure is completed to code, protecting taxpayers from inheriting unfinished improvements if the developer encounters financial difficulty.
Subdivision bonds are usually written for the full estimated cost of required public improvements, as determined by the municipality’s engineer. Premium rates usually range from 1% to 3% of the bond amount for qualified developers with strong financials.
For a development requiring $500,000 in public improvements, the subdivision bond amount would be $500,000, and the annual premium would typically range from $5,000 to $15,000, depending on creditworthiness and financial strength.
Subdivision, we issue bonds on behalf of the developer, not the contractor building the improvements. This is a critical distinction: the developer is the principal, and the municipality is the obligee. A contractor’s performance bond for the same project is a separate instrument that protects the developer, not the city.
A subdivision bond guarantees that a developer will complete required public improvements, roads, utilities, and sidewalks, before the municipality accepts the development. If the developer fails, the surety covers the cost of completion.
The developer, not the contractor. The bond is between the developer (principal), the surety, and the local government agency (obligee).
The municipality’s engineer estimates the cost of required public improvements. The bond is usually written for 100% to 120% of that estimated cost.
Many jurisdictions allow reduction riders as phases of improvement are completed and accepted. Ask your surety to include this option at the time of issuance.
