Subdivision and Site Improvement Bonds in Florida – Laying the Groundwork for Growth

Florida is one of the fastest-growing states in the country, and with that growth comes an incredible demand for new housing developments, commercial centers, and public infrastructure. Before any homes go up or businesses open their doors, there’s foundational work that must be done—grading land, installing underground utilities, building roads, and ensuring stormwater systems are in place. These early stages of development are critical, and they come with serious responsibility. That’s where subdivision and site improvement bonds come in.

For land developers, general contractors, and site work companies across Florida, these bonds are often the key to unlocking permits, satisfying municipal requirements, and keeping projects moving. They guarantee local governments and regulatory bodies that developers will complete the necessary public infrastructure improvements according to approved plans and within agreed timelines.

In this post, we break down site improvement and subdivision bonds in Florida, explain why regulators require them, show how they differ from performance and maintenance bonds, and highlight what developers must know to stay compliant. We also show how Florida Risk Partners makes it fast and easy to issue the right bond through our 24/7 quote/bind/issue platform.

What Is a Subdivision Bond?

In Florida, a subdivision bond—also called a site improvement bond or plat bond—guarantees that a developer or contractor will complete the public infrastructure improvements a city or county requires before officially approving or occupying a development.

These improvements may include:

• Roadways and curbs
• Sidewalks and bike paths
• Sewer and water mains
• Stormwater drainage systems
• Street lighting and signage
• Fire hydrants and utilities

Municipal planning departments or county development agencies typically require subdivision bonds as a condition for approving a land development permit, site plan, or final plat. These bonds protect the public interest by ensuring developers complete critical infrastructure—even if they fail to follow through.

Without a subdivision bond, a developer may not be able to record a plat, sell lots, or begin vertical construction. In many jurisdictions, it’s not just good practice—it’s a legal requirement.

Who Needs a Subdivision Bond in Florida?

Subdivision bonds are most commonly required of:

• Residential developers creating new subdivisions or communities
• Commercial developers building shopping centers, office parks, or industrial campuses
• Site contractors performing public improvements on behalf of a developer
• Builders extending roads, sewer, or drainage infrastructure to support private construction

For example, if a developer is subdividing a 100-acre property in Pasco County into a 300-home community, the county will likely require the developer to bond the public improvements (roads, sidewalks, storm drains) before the plat is recorded or any lots can be sold. If the developer fails to complete the improvements, the county can use the bond to finish the work.

These bonds are often required in advance of construction and must remain in effect until:

• The improvements are completed,
• Inspected and approved by the municipality, and
• Final acceptance is issued.

Site Improvement Bonds vs. Performance Bonds: What’s the Difference?

While performance bonds and subdivision/site improvement bonds both guarantee completion of construction work, the parties and purposes differ:

Performance Bond	Subdivision Bond
Required by a private owner or public agency	Required by a city or county
Protects the project owner	Protects the municipality/public interest
Guarantees contract completion	Guarantees infrastructure improvement for public use
Typically used for vertical construction	Typically used for horizontal/site work before vertical construction begins

In short, a site improvement bond guarantees that public improvements tied to land development will be completed per local ordinances, even if the developer abandons the project or defaults.

Florida-Specific Subdivision Bond Requirements

Each municipality or county in Florida may have its own specific bond form, required coverage percentage, and approval process. Here are a few examples from around the state:

Hillsborough County

• Requires subdivision bonds for public improvements associated with platting or site development
• Bond must cover 110%–120% of the engineer’s estimated cost of improvements
• Developer must provide engineer-sealed cost estimates and obtain approval before issuance

City of Orlando

• Requires improvement bonds before final plat approval
• Accepts surety bonds, letters of credit, or cash escrow
• Bond duration typically extends until final acceptance, plus a one-year warranty period

Collier County

• Requires performance security for infrastructure improvements
• Bond must remain in effect until all improvements are completed and accepted
• Warranty bond (10–20%) often required following completion

Before starting the bonding process, it’s essential to verify the specific requirements with the municipality’s engineering, planning, or development review department. The team at Florida Risk Partners can help guide you through that step.

How Is the Bond Amount Determined?

Unlike flat-fee license or permit bonds, subdivision and site bonds are calculated based on a percentage of the actual cost of the public improvements—not the total project cost.

A developer must usually submit:

• A sealed cost estimate from a Florida-licensed engineer
• A schedule of values breaking down each component (e.g., asphalt, concrete, drainage pipe)
• An approved construction plan

The bonding entity (typically a city or county) will review the estimate and set a required bond amount—often 110% to 125% of the projected cost to provide a buffer for inflation or contingency. For example, if your stormwater and utility installation is estimated at $1.2 million, your required bond amount may be $1.35 million.

Keep in mind that bonds must usually be renewed annually until the improvements are fully completed and accepted.

What Happens If You Don’t Secure a Required Bond?

Without the required Florida subdivision bond, your development could face:

• Delays in permitting – No bond, no permit
• Denial of final plat recording – You can’t sell or transfer lots
• Prohibition of vertical construction – Can’t pull building permits
• Loss of developer reputation and trust – Municipalities may flag you as non-compliant
• Legal consequences or fines – Non-compliance with development codes

In short, not securing the bond on time can cost you far more in delays, legal issues, and lost sales than the cost of the bond itself.

What Underwriters Look for in Subdivision Bond Applications

Because subdivision bonds can involve large dollar amounts and extended timeframes, surety companies conduct thorough underwriting. They’ll look for:

• Experience – Your history with similar development projects
• Financial stability – Clean balance sheets, net worth, and liquidity
• Engineering plans and cost estimates – Accuracy and approvals
• Bond duration and phasing – Will this be a 12-month or multi-year project?

Newer developers or those with thin financials may need personal indemnity or collateral to get approved. That’s why it’s critical to work with a bond partner who understands the Florida development process.
