What is a surety bond?

A surety bond is a three-party agreement between the contractor (principal), the project owner or public agency (obligee), and the bond company (surety). The surety promises that the contractor will meet specific obligations, like finishing the work or following licensing rules. If the contractor does not meet these obligations, the surety may step in to finish the job or pay the project owner up to the bond’s limit. The contractor must then pay back the surety for any valid claims.

Contract Bonds (deep dive)

Bid bonds

Purpose: Show you’re a serious, bondable bidder.
Typical amount: Often 5–10% of the bid (per solicitation).
If you refuse award: The obligee may claim the bond (e.g., to cover re‑procurement difference).
Pro tip: Confirm your surety can support final performance/payment bonds at your bid size before you submit.

Performance bonds

Purpose: Ensure the project is completed on time, on spec, on budget per contract.
Common claim triggers: Abandonment, chronic delays, quality/code failures, insolvency.
Surety remedies: They may finance you to finish, replace you, or bring in another contractor, choosing the option that keeps losses as low as possible.

Payment bonds

Purpose: Ensure subcontractors and suppliers are paid, preventing liens (critical on public works).
Best practices: Clear subcontracts, timely pay apps, lien waivers, prompt pay compliance.

Maintenance/Warranty bonds

Purpose: Correct covered defects for a set period after completion (often ~1 year, as specified).

Supply bonds

Purpose: Guarantee materials meet specs and are delivered as promised.

Subdivision bonds

Purpose: Guarantee developer-installed public improvements (roads, sidewalks, utilities) in new developments.

Completion bonds

Purpose: Guarantee completion by a specified date/terms—sometimes used alongside financing requirements.

Lien-Release & Retention bonds

Lien‑Release: Replace a filed mechanic’s lien with a bond during dispute resolution.
Retention (substitution) bonds: May replace cash retainage where allowed, improving contractor cash flow.

When are construction bonds required?

  • Public works: Commonly required by federal, state, and local agencies.
  • Private projects: Frequently required above certain contract values or risk thresholds.
  • Contract terms: Bid documents and contracts specify which bonds and in what amounts.
  • Subs/suppliers: May be asked to provide bonds for large or critical scopes.

How much do surety bonds cost?

Bond cost = premium rate × bond amount.

Illustrative ranges (qualification‑dependent):

  • Strong financials/credit: ~0.5%–3% of the bond amount.
  • Developing/credit‑impaired: ~3%–10%+ (collateral or funds control may apply).
  • License bonds: Often low, fixed annual premiums for well‑qualified applicants.

Examples (for illustration):

  • $25,000 license bond → ~$100–$300 annually (qualified).
  • $500,000 performance bond → ~1%–3% = $5,000–$15,000.

What affects the rate: The owner’s requirements, bond type, project size and complexity, your financials and credit, your experience, and the surety’s rate filings.

Bonding capacity explained

Sureties set two program limits based on the three Cs (Character, Capacity, Capital):

  • Single job limit: Largest bond you can carry on one project.
  • Aggregate limit: Total bonded backlog you can carry at once.

Capacity drivers:
Working capital, net worth, profitability/cash flow, CPA or reviewed statements, WIP/backlog quality, team experience on similar‑size jobs, internal controls (estimating, job cost, safety), banking support.

How to grow capacity:
Deliver clean projects, keep timely financials (annual + interim), maintain accurate WIP, diversify backlog, strengthen controls and banking, scale in measured steps.
