What Is a Subdivision Bond?
A subdivision bond (also called a subdivision improvement bond or site improvement bond) is a surety bond required by cities, counties, and municipalities to guarantee a developer completes all required public improvements tied to a subdivision project. These improvements must be built according to approved plans before lots can be released or final plats recorded.
A subdivision bond protects the public agency by ensuring improvements are completed even if the developer cannot finish the work. Required improvements may include:
- Roads, curbs, gutters, and sidewalks
- Water, sewer, and storm drainage systems
- Grading and earthwork
- Erosion control and stabilization
- On‑site and off‑site improvements
- Landscaping, lighting, and public infrastructure
If you’re developing a subdivision or recording a final plat, the governing agency will require this bond before granting approval.
Subdivision Bond Amounts and Cost
Subdivision bond amounts are typically based on the engineer’s estimate plus contingency and mobilization. Most agencies require:
- 100%–150% of the improvement cost
- Additional percentages for contingency or inflation
- Separate bonds for performance, labor & materials, or monumentation
Your premium depends on:
- Bond amount
- Credit score
- Business financials
- Experience with similar projects
- Project size and scope
Most qualified developers receive fast approvals with competitive rates.
