Kentucky Bonding Requirements Overview
Kentucky's public construction bonding requirements are governed primarily by two statutes: KRS § 45A.435, which is part of the Kentucky Model Procurement Code, and KRS § 176.080, which specifically addresses bonding for highway and transportation construction projects. Together, these statutes establish the framework for when and how surety bonds must be furnished on publicly funded construction projects throughout the Commonwealth. Understanding these requirements is essential for any contractor working on — or hoping to bid on — public projects in Kentucky.
Under KRS § 45A.435, both performance and payment bonds are required on state public construction contracts exceeding $25,000. This is one of the lowest bonding thresholds among U.S. states, reflecting Kentucky's strong commitment to protecting both project owners and the subcontractor and supplier community on public works. Each bond must be in an amount equal to 100% of the contract price. The performance bond guarantees that the contractor will complete the project in accordance with the contract documents, and the payment bond guarantees that the contractor will pay all subcontractors, laborers, and material suppliers who furnish labor, materials, or services on the project.
For highway and transportation projects, KRS § 176.080 establishes additional bonding requirements administered by the Kentucky Transportation Cabinet (KYTC). KYTC requires both performance and payment bonds on all highway construction contracts. Contractors seeking KYTC work must also be prequalified through the KYTC Contractor Prequalification Program, which evaluates the contractor's financial capacity, equipment resources, construction experience, and bonding ability to determine the maximum contract amount for which the contractor may bid.
An important distinction about Kentucky is that the state does not have a statewide general contractor licensing system or a statewide contractor license bond requirement. Kentucky does not license general contractors at the state level. Instead, contractor licensing and registration requirements are established at the local level by individual cities and counties. Some Kentucky jurisdictions — such as Louisville/Jefferson County and Lexington-Fayette Urban County — require local contractor licenses and may impose local bonding requirements, but these vary by jurisdiction. Certain specialty trades, including electrical contractors, plumbing contractors, and HVAC contractors, are licensed at the state level through the Kentucky Department of Housing, Buildings and Construction.
For federal projects located within Kentucky, the federal Miller Act (40 U.S.C. § 3131-3134) applies, requiring both performance and payment bonds on federal construction contracts exceeding $150,000. Kentucky has significant federal construction activity, particularly related to military installations such as Fort Campbell and Fort Knox, as well as federal courthouse and government building projects.
Bid Bonds in Kentucky
A bid bond is a contract surety bond submitted with a contractor's bid on a construction project. It guarantees two things: first, that the contractor will honor their bid price and enter into the contract if awarded the project; and second, that the contractor will provide the required performance and payment bonds upon contract execution. Bid bonds protect project owners from frivolous or unreliable bids and ensure that the bidding process is competitive and credible.
In Kentucky, bid bonds are commonly required on public construction projects bid through the competitive bidding processes established by the Kentucky Model Procurement Code and by local government procurement ordinances. Most invitations for bids (IFBs) and requests for proposals (RFPs) issued by Kentucky public entities specify that a bid bond or bid security must accompany the bid submission. The typical bid bond amount is 5% of the bid price, although some Kentucky agencies and local governments may require different amounts.
Kentucky's bid bond requirements apply across a wide range of public project types, including:
- Kentucky Transportation Cabinet (KYTC) highway, bridge, and road projects
- Public school construction projects for Kentucky school districts
- County and city building and infrastructure projects
- Water and wastewater treatment facility construction
- Kentucky state university and college campus construction
- State agency facility construction managed by the Finance and Administration Cabinet
- Federal military installation construction at Fort Campbell and Fort Knox
At Surety Specialist, bid bonds are always free — no premiums, no fees, no hidden costs. We issue bid bonds at no charge for Kentucky contractors, whether you have an existing bonding line or are applying for the first time. This ensures you never have to pay for the opportunity to compete on a project.
Performance Bonds in Kentucky
A performance bond guarantees that the contractor will complete the construction project in accordance with the contract documents, plans, specifications, and timeline. If the contractor defaults — by abandoning the project, performing substandard work, or failing to meet contractual deadlines — the surety is obligated to step in to ensure the project is completed.
Under KRS § 45A.435, a performance bond is required on Kentucky state public construction contracts exceeding $25,000. This low threshold means that performance bonds are required on a much broader range of public projects in Kentucky than in most other states. The requirement applies to all state agencies subject to the Kentucky Model Procurement Code. Local governments in Kentucky may set their own bonding thresholds, and many follow the state's lead by requiring bonds on relatively small contracts.
Performance bonds are routinely required on the following types of Kentucky public projects:
- KYTC highway, bridge, and transportation infrastructure projects (required on all KYTC contracts)
- State facility construction managed by the Finance and Administration Cabinet
- Public school construction and renovation projects
- City and county infrastructure projects including roads, utilities, and public buildings
- University and higher education construction projects
- Kentucky state park improvement projects
When required, the performance bond amount is set at 100% of the contract price, consistent with industry standards and the practice under the federal Miller Act. The performance bond remains in effect until the project is substantially complete and accepted by the owner. Some Kentucky contracts also require a maintenance bond or warranty provision extending beyond substantial completion.
Performance bond premiums for Kentucky contractors generally range from 1% to 3% of the contract price, depending on the contractor's financial strength, credit history, experience, and the project's size and complexity. Performance and payment bonds are typically issued together as a matched pair, and the premium covers both bonds.
Payment Bonds in Kentucky
The payment bond is a critical component of Kentucky's public construction bonding framework. KRS § 45A.435 requires a payment bond on every state public construction contract in the Commonwealth that exceeds $25,000. The payment bond guarantees that the contractor will pay all subcontractors, laborers, and material suppliers who furnish labor, materials, or services on the project.
This requirement exists because mechanic's liens cannot be placed on public property in Kentucky. On private projects, subcontractors and suppliers who are not paid can file a mechanic's lien under KRS § 376.010 et seq. to secure their interest in the property. But this remedy is not available on public projects. The payment bond serves as a substitute for mechanic's lien rights, ensuring that those who contribute labor and materials to a public project have a financial remedy if the contractor fails to pay them.
Key Requirements Under KRS § 45A.435
The payment bond must meet several specific requirements under Kentucky law:
- Bond amount: The payment bond must be in an amount equal to 100% of the contract price.
- Threshold: Required on all state public construction contracts exceeding $25,000.
- Surety qualification: The surety issuing the bond must be authorized to do business in the Commonwealth of Kentucky and must appear on the U.S. Treasury Department's Circular 570 list of approved sureties or must otherwise satisfy the financial requirements of the contracting public entity.
- Bond availability: A copy of the payment bond must be made available to any claimant who has furnished labor or materials for the project and has not been paid.
Notice Requirements for Payment Bond Claimants
The notice and claim procedures under KRS § 45A.440 are critically important for subcontractors and suppliers seeking payment on bonded Kentucky public projects. The requirements differ depending on whether the claimant has a direct contract with the contractor:
- Claimants in privity with the contractor (those with a direct contract with the bonded contractor) are not required to serve a preliminary notice as a condition of making a claim on the payment bond.
- Claimants not in privity with the contractor (sub-subcontractors, second-tier suppliers, and others without a direct contract with the contractor) must give written notice to the contractor within 90 days after the date on which the claimant performed the last of the labor or furnished the last of the materials for which the claim is made. The notice must state the amount claimed and the name of the party for whom the work was done or materials supplied.
- Method of service: The notice must be served by registered or certified mail.
Suit Deadline
Under KRS § 45A.440, no action on the payment bond may be commenced after one year from the date on which the claimant last performed labor or last furnished materials. This one-year statute of limitations is strictly enforced by Kentucky courts. A claimant who misses this deadline loses their right to recover on the bond, regardless of the merits of their claim. It is therefore essential for subcontractors and suppliers to track their last furnishing date carefully and to consult with legal counsel well before the deadline approaches.
Subdivision Bonds in Kentucky
Subdivision bonds (also called site improvement bonds or plat bonds) are required by Kentucky counties and cities when a land developer subdivides property and is responsible for constructing public improvements. These improvements typically include roads, sidewalks, curbing, storm drainage, water and sewer lines, street lighting, and landscaping within public rights-of-way.
In Kentucky, subdivision bond requirements are established at the local level by individual counties and cities through their subdivision regulations. The bond guarantees that the developer will complete the required public improvements according to the approved site plans, engineering drawings, and applicable building codes. If the developer fails to complete the improvements, the local government can draw on the bond to hire another contractor to finish the work.
Kentucky's approach to land development is shaped by the state's planning and zoning enabling legislation, including KRS Chapter 100 (Planning and Zoning), which authorizes local planning commissions to adopt subdivision regulations. These local regulations establish the standards for public improvements in new developments and determine when subdivision bonds are required. Kentucky's growth areas — particularly the Louisville metropolitan area, Lexington, Northern Kentucky (adjacent to Cincinnati), and Bowling Green — generate significant demand for subdivision bonds as residential and commercial development continues to expand.
The bond amount is typically determined by the local government's engineer based on the estimated cost of the required improvements, and it often equals 100% to 120% of that estimate. Premiums for Kentucky subdivision bonds generally range from 1% to 3% of the bond amount, depending on the developer's financial condition, credit, and experience. Kentucky developers working in multiple jurisdictions should be aware that bond requirements and amounts can vary from one county or city to another.
Kentucky Contractor Licensing
Kentucky takes a decentralized approach to contractor licensing. Kentucky does not license general contractors at the state level. There is no statewide general contractor license issued by a state board or agency. Instead, contractor licensing and registration requirements are established at the local level by individual cities and counties.
- Local Contractor Licenses: Many Kentucky cities and counties require contractors to obtain a local license or registration before performing construction work within their jurisdiction. Louisville/Jefferson County (Louisville Metro) requires a contractor license through Louisville Metro Government. Lexington-Fayette Urban County Government has its own licensing requirements. Other cities and counties throughout the state may have their own local requirements, including examinations, insurance, and in some cases local bonding. The specific requirements vary by jurisdiction.
- State-Licensed Specialty Trades: While general contractors are not licensed at the state level, certain specialty trades are licensed through the Kentucky Department of Housing, Buildings and Construction. These include licensed electricians, licensed plumbers, licensed HVAC contractors, and licensed boiler installers. Each specialty category has its own examination and experience requirements.
Kentucky does not require a statewide contractor license bond because the state does not issue a statewide general contractor license. Some local jurisdictions may require a bond as part of their local licensing process, but these requirements vary. This distinguishes Kentucky from states like California ($25,000 license bond), Nevada ($5,000 to $100,000 license bond), and Arizona ($2,500 to $16,000 license bond based on license class). Contractors working in Kentucky should check with the specific city or county where they plan to perform work to determine local licensing and bonding requirements.
Notice & Claim Requirements in Kentucky
Understanding Kentucky's notice and claim requirements is essential for subcontractors, laborers, and material suppliers working on bonded public construction projects. The procedures under KRS § 45A.440 are specific and strictly enforced, and failure to comply can result in the loss of payment bond rights. Below is a detailed breakdown of the key timelines and requirements.
| Requirement | Details |
|---|---|
| Bond threshold (state) | Performance and payment bonds required on Kentucky state public construction contracts exceeding $25,000 under KRS § 45A.435. |
| Bond threshold (federal in KY) | Performance and payment bonds required on federal construction contracts exceeding $150,000 under the federal Miller Act. |
| Notice (claimants in privity) | Claimants who have a direct contract with the contractor are not required to serve a preliminary notice as a condition of their claim rights. |
| Notice (claimants not in privity) | Must give written notice to the contractor within 90 days after the date on which the claimant performed the last of the labor or furnished the last of the materials. The notice must state the amount claimed and identify the party for whom the work was done. |
| Method of notice | Registered or certified mail. |
| Suit deadline | No action on the payment bond may be commenced after 1 year from the date on which the claimant last performed labor or last furnished materials. |
| Where to file suit | Actions on the payment bond must be brought in the circuit court of the county in which the project is located. |
| Attorneys' fees | Kentucky law does not provide a general statutory right to attorneys' fees in payment bond actions; recovery of fees depends on the bond terms and applicable contract provisions. |
These notice and claim provisions are distinct from the requirements under Kentucky's private mechanic's lien law (KRS § 376.010 et seq.). On private projects, subcontractors and suppliers must comply with specific notice and recording requirements to preserve their lien rights. On public projects governed by KRS § 45A.440, the notice requirements are different, and the remedies run against the payment bond rather than the property. Contractors, subcontractors, and suppliers should be careful not to confuse these two separate sets of requirements.
Frequently Asked Questions About Kentucky Contract Bonds
Under KRS § 45A.435, both performance and payment bonds are required on Kentucky state public construction contracts exceeding $25,000. This is one of the lowest bonding thresholds among U.S. states. Each bond must be in an amount equal to 100% of the contract price. For highway and transportation projects, KRS § 176.080 establishes additional requirements administered by the Kentucky Transportation Cabinet (KYTC). Local governments may set their own thresholds as well.
The notice requirements depend on whether the claimant has a direct contract with the bonded contractor. Claimants who are in privity (have a direct contract with the contractor) are not required to serve a preliminary notice. Claimants who are not in privity (sub-subcontractors, second-tier suppliers, etc.) must give written notice to the contractor within 90 days after the date on which the claimant performed the last of the labor or furnished the last of the materials for which the claim is made. The notice must state the amount claimed and the name of the party for whom the work was done. It must be served by registered or certified mail.
Under KRS § 45A.440, no action on the payment bond may be commenced after one year from the date on which the claimant last performed labor or last furnished materials. This statute of limitations is strictly enforced by Kentucky courts. Missing this deadline bars the claimant from recovering on the bond. Claimants should track their last furnishing date carefully and consult with an attorney well before the one-year deadline expires.
No. Kentucky does not have a statewide contractor licensing system for general contractors and therefore does not have a statewide contractor license bond requirement. Contractor licensing in Kentucky is handled at the local level by individual cities and counties. Some jurisdictions — such as Louisville Metro and Lexington-Fayette Urban County — require local contractor licenses and may impose local bonding requirements, but these vary by jurisdiction. Certain specialty trades (electrical, plumbing, HVAC) are licensed at the state level through the Department of Housing, Buildings and Construction.
The Kentucky Transportation Cabinet (KYTC) has specific bonding requirements for highway and transportation construction projects governed by KRS § 176.080. KYTC generally requires both performance and payment bonds on all highway construction contracts. Contractors seeking KYTC work must be prequalified through KYTC's Contractor Prequalification Program, which evaluates a contractor's financial capacity, equipment resources, construction experience, and bonding ability to determine the maximum contract amount for which the contractor may bid. KYTC projects include highway construction and resurfacing, bridge construction and rehabilitation, and other transportation infrastructure improvements.
No. Mechanic's liens cannot be filed against public property in Kentucky. This is a fundamental principle of construction law that applies in all 50 states. On Kentucky public projects, the payment bond required under KRS § 45A.435 serves as the substitute for mechanic's lien rights. If you are a subcontractor or supplier who has not been paid on a Kentucky public project, your remedy is to make a claim against the contractor's payment bond rather than filing a lien. On private projects, Kentucky's mechanic's lien statute (KRS § 376.010 et seq.) provides lien rights.
Kentucky contract bond premiums typically range from 1% to 3% of the bond amount (which usually equals the contract price) for well-qualified contractors. The exact premium rate depends on several factors, including the contractor's personal and business credit scores, financial statements (balance sheet strength, working capital, net worth), years of construction experience in Kentucky, project size and type, and current work backlog. New contractors or those with credit challenges may pay higher rates. Bid bonds are always free through Surety Specialist. As an example, a Kentucky contractor bonding a $1,000,000 public project might pay $10,000 to $25,000 in combined performance and payment bond premiums.
