What is a Bid Bond?
A bid bond is a type of surety bond that contractors provide during the bidding process for construction or development projects in real estate. It guarantees that if the contractor wins the bid, they will sign the contract and provide the necessary performance and payment bonds. This protects property owners or developers from financial losses or delays if the contractor backs out.
For example, if a contractor bids $500,000 on a project but then refuses to sign the contract, the project owner can claim against the bid bond (typically 5-10% of the bid) to cover rebidding costs.

Key Points
- A bid bond is a financial guarantee for real estate construction projects, ensuring contractors follow through on bids.
- It protects investors from financial loss if a contractor backs out after winning a contract.
- Research suggests bid bonds are crucial for large projects, especially public ones, to ensure accountability.
- The evidence leans toward bid bonds being cost-effective, often free or low-cost for qualified contractors.
Why It Matters for Real Estate Investors
Bid bonds are essential for real estate investors, especially in large-scale projects, as they:
- Ensure contractors are financially capable and serious about their bids.
- Prevent delays and additional costs from contractor defaults.
- Promote fair competition, particularly in taxpayer-funded projects.

The Role of Bid Bonds in Real Estate
In the realm of real estate, particularly in construction and development, ensuring project continuity is paramount. Bid bonds serve as a financial safeguard, guaranteeing that contractors adhere to their bids. This is especially relevant for investors managing large-scale projects, where delays or financial losses can significantly impact returns. The information gathered from various sources, including financial and construction-focused platforms, highlights bids as a critical tool for risk mitigation.
A Detailed Look at Bid Bonds
A bid bond is a legal agreement, often classified as a surety bond, that ensures contractors fulfill their project obligations. Specifically, it guarantees that if a contractor wins a bid, they will:
- Enter into the contract at the agreed price.
- Provide performance and payment bonds before commencing work.
The bond involves three key parties:
- Principal: The contractor or bidder purchasing the bond.
- Obligee: The project owner or developer requiring the bond, such as a real estate investor.
- Surety: The bonding company issuing the bond, acting as a financial guarantor.
For instance, if a contractor bids $500,000 on a commercial development and then backs out, the project owner can claim against the bid bond, typically set at 5-10% of the bid (e.g., $25,000 to $50,000). This compensation covers costs like rebidding, ensuring the project can move forward without significant financial strain.
Sources such as Investopedia emphasize that bid bonds provide both financial and legal recourse, protecting owners from underfunded or frivolous bids. This is particularly vital in real estate, where construction projects often involve substantial investments.
Operational Mechanics
The process begins when a contractor submits a bid, accompanied by a bid bond, usually amounting to 5-10% of the total bid price. For federally funded projects, the Miller Act mandates a 20% bond, as noted by Procore. Here’s a detailed breakdown:
- Bid Submission: The contractor includes the bid bond with their proposal, signaling financial commitment.
- Bid Evaluation: The project owner reviews bids, selecting the lowest qualified bidder.
- Contract Award: The winning contractor must sign the contract and provide performance and payment bonds.
- Claim Process: If the contractor fails to comply, the owner can file a claim against the bond. The surety compensates up to the bond amount, which may cover the difference between the original bid and the next lowest bid (e.g., if the original bid is $500,000 and the next is $525,000, the claim could be $25,000).
Claims against bid bonds are rare but occur due to errors in bidding, such as underbidding, as highlighted by Surety First. The contractor and surety are jointly and severally liable, meaning the surety may seek reimbursement from the contractor based on bond terms.
Cost and Accessibility for Contractors
The cost of a bid bond typically ranges from 0.5% to 1% of the bid amount, but JW Surety Bonds notes that many surety companies offer them for free to qualified contractors, given the low risk involved. Factors influencing cost include:
- Jurisdiction and local regulations.
- The contractor’s creditworthiness and financial stability.
- The size and complexity of the project.
For smaller projects (≤ $350,000), contractors may only need a bid bond request form, while larger projects require detailed financials, such as job costs, subcontractor bids, and CPA-prepared reports, as per Procore.
Legal Framework and Requirements
Bid bonds are legally required for most federal construction projects under the Miller Act, ensuring contractors can perform as bid. This is crucial for public projects, where taxpayer money is involved, and is often extended to state and local levels. Private developers may also require bid bonds, especially for large commercial or residential developments, to mitigate risk.
The penal sum, or bond amount, is typically 5-10% for non-federal projects, but federal contracts may require up to 20%, as seen in examples like a $250,000 bid needing a $50,000 bond for federal work, according to Investopedia.
Importance for Real Estate Investors
For real estate investors, bid bonds are indispensable, particularly in large-scale construction. They:
- Filter out unserious bidders, ensuring only financially capable contractors participate.
- Protect against defaults, covering costs like rebidding, which can delay projects and inflate budgets.
- Promote fair competition, especially in public projects funded by taxpayers, as noted by Procore.
In real estate, where projects can involve millions, bid bonds mitigate risks of contractor withdrawal, ensuring project timelines and budgets are maintained. For instance, a developer bidding out a multi-million-dollar commercial project can rely on bid bonds to avoid the financial strain of rebidding.
Comparison with Other Bonds
Bid bonds are part of a broader bonding ecosystem in construction. Here’s a comparison with related bonds, based on insights from Investopedia and JW Surety Bonds:
| Bond Type | Purpose | When It Applies |
|---|---|---|
| Bid Bond | Guarantees contractor will sign contract and provide other bonds | During bidding phase |
| Performance Bond | Ensures project completion as per contract terms | After contract award, during construction |
| Payment Bond | Ensures payment to subcontractors and suppliers | After contract award, during construction |
Bid bonds are replaced by performance and payment bonds once the contract is awarded, providing continuous protection throughout the project lifecycle.
Practical Tips for Real Estate Investors
To effectively utilize bid bonds, investors should:
- Mandate Bid Bonds: Especially for large or public projects, make them a standard requirement in bidding documents.
- Understand Terms: Ensure the bond covers potential rebidding costs, typically 5-10% of the bid.
- Verify Sureties: Work with reputable surety companies to ensure bond validity, as seen in guidance from JW Surety Bonds.
- Know Local Laws: Be aware of jurisdiction-specific requirements, as bid bound percentages and legal obligations vary.
For example, for a $1 million project, requiring a 10% bid bond ($100,000) ensures significant protection against contractor defaults, aligning with best practices outlined by Procore.
FAQ: Bid Bonds in Real Estate
Who are the parties involved?
There are three key parties in a bid bond arrangement. The first is the principal, who is the contractor purchasing the bond. The second is the obligee, who is the project owner or developer requiring the bond. The third is the surety, which is the bonding company that provides the financial guarantee and steps in if the contractor fails to meet their obligations.
What happens if a contractor defaults on a bid?
If a contractor who wins the bid refuses to sign the contract or otherwise fails to follow through with the agreed-upon work, the project owner has the right to make a claim against the bid bond. The surety company will then compensate the owner up to the bond amount, which can cover additional costs such as rebidding the project or paying the difference between the original bid and the next lowest acceptable offer.
Are these required for all real estate projects?
Bid bonds are legally required for most federally funded construction projects under the Miller Act. Many state and municipal projects also include this requirement. While private developers are not always obligated to use bonds, it is considered a best practice, especially for large or complex developments where the financial stakes are high.
Conclusion
Bid bonds are a cornerstone of risk management in real estate construction, ensuring contractors are accountable and projects proceed smoothly. By requiring it, investors can safeguard their investments, minimize delays, and maintain financial stability.
