Colorado Performance BondLocal, State & CDOT — Not One Rule
Colorado does not run a single performance bond statute. A county road contract, a state agency building, and a CDOT highway project each answer to a different chapter of law, with different dollar triggers and different pre-bid steps. Get the wrong one and you either under-bond a public job or waste weeks on a prequalification process that never applied to you. This page walks through all three — plus the final-settlement claim clock that catches more Colorado subs and suppliers than any bond amount question.
Colorado Doesn't Have One Performance Bond Law — It Has Three
A performance bond is required on Colorado public works whenever the awarding body and the dollar figure clear the applicable threshold, and which threshold applies depends entirely on who awarded the contract:
The local-government track is also structurally different from the other two: § 38-26-106(2) writes it as one combined bond securing both faithful performance and payment of labor and materials, at a statutory floor of 50% of the contract price. State agency and CDOT contracts under § 24-105-202 require two separate instruments — a performance bond and a payment bond, each independently set at 50%. Price your bid off the wrong structure and you will either under-quote the bond or hand the agency the wrong paperwork at award. For the combined federal picture on projects that cross state lines, see our Miller Act requirements guide.
Official Colorado Requirements
"Before entering upon the performance of any work included in the contract, a contractor shall duly execute, deliver to, and file with the board, officer, body, or person by whom the contract was awarded a good and sufficient bond or other acceptable surety... in a penal sum not less than one-half of the total amount payable under the terms of the contract."Colorado Revised Statutes • C.R.S. § 38-26-106(1)
The Final-Settlement Clock: Colorado's Most-Missed Deadline
Colorado does not use mechanics' liens against public property, so a payment bond claim under § 38-26-107 is often the only recovery path for an unpaid sub or supplier on a public job. The process runs on a published notice and a hard 90-day window — miss either side of it and the claim can be barred entirely, independent of whether the money is owed.
Bond Filed at Contract Start
Contractor executes the § 38-26-106 bond before starting work — this is the instrument every later claim runs against.
Work Completes, Settlement Date Set
The contracting body fixes a date for final settlement once the contract work is substantially complete.
Publication (Contracts Over $150K)
Notice published at least twice in a newspaper of general circulation, or an approved electronic medium, no later than 10 days before settlement.
90-Day Claim Window
Unpaid claimants must commence action within 90 days after the settlement date. File a lis pendens with the contracting body to keep funds withheld while the case proceeds.
Below $150,000: the publication requirement in § 38-26-107 does not apply, but subs and suppliers still keep their direct-suit right under § 38-26-105 within six months of completion. Track your own completion date — there may be no public notice to remind you.
CDOT Prequalification: The Gate Before You Can Bid
Highway and bridge work runs on a separate statutory track from § 38-26-106. CDOT bidding is governed by the Construction Bidding for Public Projects Act (Title 24, Article 92) and implemented through 2 CCR 601-10. Only prequalified contractors may bid at all — the performance bond amount is the last step, not the first gate.
The 17-Day Rule (Both Directions)
- New or renewal prequalification applications go in at least 17 calendar days before the bid opening you intend to bid on.
- CDOT's Contracts and Market Analysis Branch returns approval or disapproval within 17 calendar days of receiving a complete application.
- Disapproved? You have 60 calendar days to appeal in writing to the CDOT Chief Engineer.
Four Prequalification Levels
- $0 – $3,000,000No CPA review required
- $3,000,000 – $5,000,000CPA-reviewed statement
- $5,000,000 – $20,000,000CPA-audited + affidavit
- Over $20,000,000CPA-audited + affidavit
CDOT's bid-capacity levels split the top end into $5M–$20M and over-$20M bands, but the audit-and-affidavit requirement itself is identical above $5,000,000 under 2 CCR 601-10 § 2.02.1(i) — the higher band raises how large a project you can bid on, not how the financials get reviewed.
The Financial Ratios CDOT Screens On (2 CCR 601-10 § 2.04.1(d))
Miss a benchmark and CDOT can still weigh irrevocable lines of credit, officer loans, or a dated bonding-capacity letter before ruling on prequalification — it is not an automatic denial, but it is a conversation worth having with your surety before you submit.
Every application must also include a bonding-capacity letter — signed and dated within the last two months — stating your single-project performance bond capacity. We issue that letter for your CDOT prequalification file, separate from the bond itself, which is executed once you are actually awarded the contract.
What a $2,000,000 Municipal Contract Actually Costs in Bond Terms
The penal sum — not the contract price — is what your premium is calculated against. Here is the statutory floor on a local-government award, and how it compares to a state or CDOT contract of the same size.
Local Government Penal Sum Floor
C.R.S. § 38-26-106(1). Many counties and municipalities set the penal sum at 100% of the contract price by contract terms — confirm the actual figure in the bid documents before pricing your premium.
Colorado Performance Bond Structure by Awarding Body
Based on a $2,000,000 contract example
| Factor | Local Government | State Agency (Non-CDOT) | CDOT |
|---|---|---|---|
| Governing Law | § 38-26-105 / § 38-26-106 | § 24-105-202 | 2 CCR 601-10 (Title 24, Art. 92) |
| Dollar Threshold | Over $50,000 | Over $150,000 | Public Project ≥$150,000/fiscal year |
| Bond Structure | One combined performance + payment bond | Separate performance AND payment bonds | Separate bonds, per § 24-105-202 |
| Statutory Floor on $2M | $1,000,000 (50%) | $1,000,000 + $1,000,000 (50% each) | $1,000,000 + $1,000,000 (50% each) |
| Pre-Bid Step | None beyond the solicitation | None specified in statute | Prequalification 17 days before bid opening |
| Claims Process | Direct suit within 6 months (§ 38-26-105) | Final settlement / § 38-26-107 process | Same Title 24 payment bond process |
| Obligee | County, city, or school district | State agency (non-transportation) | Colorado Department of Transportation |
Statutory penal sums are floors, not caps — agencies routinely require higher percentages in the contract documents. Confirm the actual required amount in your specific solicitation.

Supply Contracts and Maintenance Work Trigger the Same Bond
Colorado's bonding statutes do not limit “public works” to new construction. § 38-26-105 and § 38-26-106 both define public works to include the construction, erection, repair, maintenance, or improvement of covered public property — the same $50,000 (local) and $150,000 (state) thresholds apply whether you are building a bridge or maintaining one.
Two situations catch contractors who assume the bond requirement only applies to ground-up construction:
Maintenance Contracts
A multi-year county road resurfacing or municipal facilities maintenance contract over $50,000 is a public work under the statute's own text — the bond requirement does not reset because the work is ongoing rather than a single build. See our maintenance bond guide for how these differ from a warranty bond on a completed project.
Supply & Equipment Contracts
Equipment and material supply contracts tied to a public works project frequently require their own bond, separate from the general contractor's performance bond on the underlying job. Review our supply bond page if you are quoting materials or equipment into a Colorado public contract rather than the labor itself.
Colorado Performance Bond Cost by Contract Size
Premiums scale with contract size and underwriting depth, not a flat percentage. A local county contract under $500,000 usually clears underwriting on the application alone. Above that, the same financial-statement tiers that drive CDOT's prequalification levels tend to drive your surety's underwriting depth too. For a broader breakdown, see our performance bond cost guide or run the numbers on our performance bond calculator.
Underwriting depth in Colorado:
Performance Bond Premium by Credit Tier
Based on a Varies by contract bond amount
- Excellent (750+)Rate: 0.5-1.5%$5,000-$15,000
- Good (680-749)Rate: 1.5-3%$15,000-$30,000
- Fair (620-679)Rate: 3-5%$30,000-$50,000
- Below 620Rate: 5-10%+$50,000-$100,000+
Based on a $1,000,000 bond amount. Actual premium depends on contract size, awarding body, contractor financials, and surety carrier.
Colorado Performance Bond Questions
Specific to Colorado statutes, CDOT prequalification, and claims timelines
My subcontract is with the general contractor, not the county — can I still sue the bond directly if I do not get paid?
Yes. C.R.S. § 38-26-105 lets any person, copartnership, association, company, or corporation "supplying or furnishing labor, laborers, materials, rental machinery, tools, or equipment" sue the bond directly, whether your contract runs through the prime contractor or a subcontractor. You do not need privity with the county or municipality. The catch is timing: the statute requires the action to be brought within six months after completion of the work. That clock is separate from and shorter than the 90-day final-settlement claim window under § 38-26-107 — miss the six-month deadline and the direct-suit right on the payment bond is gone regardless of what the final settlement notice said.
I missed the final settlement publication notice — is my claim on a Colorado public works bond dead?
Not necessarily, but the clock is unforgiving once the notice runs. Under § 38-26-107, on any contract over $150,000 the contracting body must publish notice of final settlement at least twice in a newspaper of general circulation (or an approved electronic medium) no later than ten days before the settlement date. Once that date passes, you have 90 days to commence an action against the bond or the withheld funds get released. If you are inside the 90 days, file immediately — including a notice of lis pendens with the contracting body — because that filing is what extends the fund-withholding beyond the 90-day mark while your case proceeds. If the 90 days have already run and no action was filed, the practical recovery path narrows sharply; talk to construction counsel about whether the contracting body actually complied with the publication requirement, since a defective publication can reopen the window.
Does a $120,000 county road resurfacing contract need a performance bond in Colorado?
Yes. The local-government threshold under § 38-26-105 and § 38-26-106(3)(a) is contracts over $50,000 — a $120,000 county contract is well past it. What often surprises contractors is that Colorado bonds this differently than states with separate performance and payment bonds: § 38-26-106(2) makes it one combined penal bond that secures both faithful performance of the contract and payment to labor and material suppliers, set at a statutory floor of 50% of the contract price ($60,000 minimum here), though many counties and municipalities set the penal sum at 100% by contract terms. Confirm which the county actually requires before you price the bond into your bid — the difference between $60,000 and $120,000 of bonded exposure changes your premium meaningfully.
My CDOT project is valued around $130,000 — do I still need to go through bidder prequalification?
Probably not through the full 2 CCR 601-10 prequalification process, but confirm with the specific Invitation for Bids. The rules define a "Public Project" as CDOT highway, bridge, or maintenance work "for which appropriation or expenditure of funds may be reasonably expected to exceed one hundred fifty thousand dollars in the aggregate for any fiscal year." A single $130,000 contract sits under that figure. But CDOT calculates the aggregate across everything you might be awarded that fiscal year, not just the one project in front of you — and the Invitation for Bids itself can impose Special Prequalification criteria regardless of contract size. Do not assume you are exempt; check the specific solicitation.
Is the CDOT bonding capacity letter the same document as my actual performance bond?
No — they serve different purposes and happen at different stages. The bonding capacity letter is a prequalification document: 2 CCR 601-10 § 2.02.1(j) requires every application to include "a recently signed and dated letter from the bonding agent or bonding company indicating the single project performance bond capacity for the Contractor." Section 2.04.1(d) adds the age limit — when CDOT relies on that letter to evaluate your financial capability, it "cannot be more than two months old upon receipt" by CDOT. That letter tells CDOT you can bond a project of a given size — it is not the bond itself and does not secure any contract. The actual performance bond gets executed after you are awarded a specific contract, sized to that contract's value under § 24-105-202. We issue both: the capacity letter for your prequalification file, then the bond once you win the award.
What happens if my company does not meet one of CDOT's four prequalification financial ratio benchmarks?
It is not an automatic disqualification. CDOT's presumptive ratios under 2 CCR 601-10 Section 2.04.1(d) are Total Current Assets to Total Current Liabilities greater than 1.0, Cash and Accounts Receivable to Total Current Liabilities greater than 1.0, Net Fixed Assets to Net Worth less than 2.3, and Total Liabilities to Net Worth less than 4.0. If your financials fall outside one of those ranges, the rule explicitly lets the Contracts and Market Analysis Branch Manager consider other factors — irrevocable lines of credit, officer loans to the company, or that same bonding-capacity letter — before denying prequalification. Falling short on one ratio is a conversation to have with your surety before you apply, not a reason to skip bidding.
