Michigan Bonding Requirements Overview
Michigan's public construction bonding requirements are governed primarily by MI Comp Laws § 129.201 et seq., which establishes the framework for when and how surety bonds must be furnished on publicly funded construction projects throughout the Great Lakes State. Understanding these requirements is essential for any contractor working on — or hoping to bid on — public projects in Michigan.
Under MI Comp Laws § 129.201, both performance and payment bonds are required on all public construction projects in Michigan that exceed $50,000. This is a statutory mandate that applies to contracts awarded by the state of Michigan, counties, cities, villages, townships, school districts, community colleges, public universities, and all other political subdivisions. Michigan's $50,000 threshold is lower than many other states, reflecting the state's strong commitment to protecting both governmental entities and the subcontractors, laborers, and material suppliers who work on public projects.
Each bond — both the performance bond and the payment bond — must be in an amount equal to the contract price. The performance bond guarantees that the contractor will complete the project in accordance with the contract documents. The payment bond guarantees that the contractor will pay all subcontractors, laborers, and material suppliers who furnish labor, materials, or services on the project.
Michigan is also notable for requiring a $10,000 residential builder's license bond for residential builders and maintenance and alteration contractors. This bond is administered through the Michigan Department of Licensing and Regulatory Affairs (LARA) under the Residential Builders and Maintenance and Alteration Contractors Act (MCL § 339.2401 et seq.). The bond protects homeowners against financial loss caused by a contractor's failure to comply with the Act. Commercial general contractors are not required to post a statewide license bond, though individual municipalities may impose their own requirements.
Michigan's bonding framework also intersects with the state's prevailing wage requirements (governed by the Michigan Prevailing Wage Act for state-funded projects) and its competitive bidding requirements under various procurement statutes. Contractors working on Michigan public projects must understand how these overlapping requirements affect their bidding, bonding, and contracting obligations.
Bid Bonds in Michigan
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 Michigan, bid bonds are commonly required on public construction projects bid through the state's competitive bidding process. Most invitations for bids (IFBs) issued by Michigan governmental 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, consistent with standard industry practice and the requirements of most Michigan state agencies and municipalities.
Michigan's bid bond requirements apply across a wide range of public project types, including:
- Michigan Department of Transportation (MDOT) highway, bridge, and road construction projects
- School district construction and renovation projects (K-12 and intermediate school districts)
- County and municipal building and infrastructure projects
- Water and wastewater treatment facility construction
- University of Michigan, Michigan State University, and other public university campus projects
- State of Michigan facility construction managed by the Department of Technology, Management & Budget (DTMB)
- Community college construction and renovation projects
- Public hospital and healthcare facility construction
At Surety Specialist, bid bonds are always free — no premiums, no fees, no hidden costs. We issue bid bonds at no charge for Michigan 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 Michigan
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 MI Comp Laws § 129.201, performance bonds are required on all Michigan public construction projects exceeding $50,000. This is a statutory mandate, not a discretionary requirement. The performance bond must be in an amount equal to the contract price. This requirement applies to all Michigan governmental entities, including the state, counties, cities, villages, townships, school districts, and other political subdivisions.
Performance bonds are routinely required on a wide range of Michigan public projects, including:
- MDOT highway and bridge construction and rehabilitation projects
- Public school construction and major renovation projects
- Municipal infrastructure projects (roads, water, sewer, public facilities)
- State government building construction and renovation
- Public university and community college campus construction
- County road commission 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 Michigan contracts also include a maintenance or warranty provision extending beyond substantial completion, typically for one year.
Performance bond premiums for Michigan 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 Michigan
The payment bond is a critical component of Michigan's public construction bonding framework. MI Comp Laws § 129.201 requires a payment bond on every public construction project in the state that exceeds $50,000. 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 construction liens (Michigan's equivalent of mechanic's liens) cannot be placed on public property. On private projects, subcontractors and suppliers who are not paid can file a construction lien under the Michigan Construction Lien Act (MCL § 570.1101 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 construction 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 MI Comp Laws § 129.201
The payment bond must meet several specific requirements under Michigan law:
- Bond amount: The payment bond must be in an amount equal to the contract price.
- Threshold: Required on all public construction projects exceeding $50,000.
- Surety qualification: The surety issuing the bond must be authorized to do business in the state of Michigan and must meet the financial requirements of the contracting governmental entity.
- Scope of coverage: The payment bond protects subcontractors, laborers, and material suppliers who furnish labor or materials for the public project.
Notice Requirements for Payment Bond Claimants
Michigan's notice requirements for payment bond claimants are notably different from many other states. Under MI Comp Laws § 129.207, the requirements depend on the claimant's contractual relationship with the bonded 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 serve a written notice on both the contractor and the governmental entity within 30 days after the claimant first furnished labor or materials. This is a critical distinction from many other states — Michigan requires notice within 30 days of first furnishing, not after last furnishing. The notice must identify the claimant, the project, and the nature of the work or materials being provided.
- Method of service: The notice must be served by certified mail (return receipt requested) or by hand delivery.
This early notice requirement is one of the most important features of Michigan's payment bond law. Many subcontractors and suppliers in other states are accustomed to giving notice after completing their work. In Michigan, the notice must be given at the beginning of the work, within 30 days of first furnishing. Failure to provide timely notice can result in the loss of payment bond rights for claimants not in privity with the contractor.
Suit Deadline
Under MI Comp Laws § 129.211, no action may be brought on the payment bond after one year from the date of final completion and acceptance of the public project by the governmental entity. This deadline is notable because it runs from the project completion date, not from the claimant's last furnishing date. This can work either for or against a claimant depending on the timing of their work relative to the project's overall completion. Claimants should monitor the project's completion status and consult with legal counsel well before the deadline approaches.
Subdivision Bonds in Michigan
Subdivision bonds (also called site improvement bonds or plat bonds) are required by Michigan counties, cities, and townships 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 Michigan, subdivision bond requirements are established at the local level through municipal ordinances and land division regulations. The Michigan Land Division Act (MCL § 560.101 et seq.) provides the statewide framework for subdivision plat approval, and individual municipalities establish specific requirements for infrastructure improvements and the financial guarantees (including surety bonds) that developers must provide. The bond guarantees that the developer will complete the required public improvements according to the approved site plans, engineering drawings, and applicable building codes.
Michigan's development landscape spans diverse environments — from the densely developed metropolitan areas of Detroit, Grand Rapids, and Ann Arbor to rural townships and lakefront communities across the state. Subdivision bond requirements can vary significantly depending on the jurisdiction. Major metropolitan areas and growing suburban communities tend to have the most detailed bonding requirements, while smaller rural townships may have simpler standards.
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 Michigan subdivision bonds generally range from 1% to 3% of the bond amount, depending on the developer's financial condition, credit, and experience. Michigan developers working in multiple jurisdictions should be aware that bond requirements and amounts can vary significantly from one municipality to another.
Michigan Contractor Licensing
Construction contractor licensing in Michigan is administered by the Michigan Department of Licensing and Regulatory Affairs (LARA) through its Bureau of Professional Licensing. Michigan's licensing requirements vary depending on the type of construction work being performed:
- Residential Builders: Contractors who build, repair, or alter residential structures (one- to four-family dwellings) must obtain a residential builder's license. Applicants must pass an examination, demonstrate at least three years of relevant experience (or equivalent education), carry required insurance, and post a $10,000 residential builder's license bond. The bond protects homeowners against financial loss resulting from the contractor's failure to comply with the Residential Builders and Maintenance and Alteration Contractors Act.
- Maintenance and Alteration Contractors: Contractors who perform maintenance, alteration, or repair work on residential structures (but do not build new structures) must obtain a maintenance and alteration contractor's license. This license also requires a $10,000 license bond.
- Commercial and Industrial Contractors: Michigan does not require a statewide license for commercial or industrial general contractors. Licensing requirements for commercial contractors are established at the local (city or township) level. Some Michigan municipalities require local contractor licensing and may impose their own bond requirements.
- Specialty Trades: Michigan licenses certain specialty trades at the state level, including electrical contractors (through the Electrical Administrative Board) and mechanical contractors (plumbing, HVAC). These specialties have their own examination, experience, and bonding requirements.
The $10,000 residential builder's license bond is separate from contract surety bonds (bid, performance, and payment bonds). The license bond is a condition of holding a residential builder's or maintenance and alteration contractor's license and remains in effect as long as the license is active. It provides a remedy for homeowners who suffer financial loss due to the contractor's violation of Michigan's residential construction laws. The bond does not cover disputes on commercial or public projects.
Michigan also operates a Homeowner Construction Lien Recovery Fund, which provides an additional layer of protection for homeowners beyond the license bond. This fund, administered by LARA, can compensate homeowners who suffer losses due to a residential builder's failure to pay subcontractors, among other covered claims.
Notice & Claim Requirements in Michigan
Understanding Michigan's notice and claim requirements is essential for subcontractors, laborers, and material suppliers working on bonded public construction projects. The procedures under MI Comp Laws § 129.201 et seq. 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 | Both performance and payment bonds required on public projects exceeding $50,000. |
| Notice (claimants in privity) | Claimants who have a direct contract with the contractor are not required to serve a preliminary notice. |
| Notice (claimants not in privity) | Must serve written notice on the contractor and the governmental entity within 30 days after first furnishing labor or materials. This is an early notice requirement — not after last furnishing. |
| Method of notice | Certified mail (return receipt requested) or hand delivery. |
| Suit deadline | No action on the payment bond may be brought after 1 year from the date of final completion and acceptance of the project by the governmental entity. |
| Where to file suit | Actions must be brought in the circuit court for the county where the project is located. |
| Bond amount | Both performance and payment bonds must equal the full contract price. |
These notice and claim provisions are distinct from the requirements under Michigan's Construction Lien Act (MCL § 570.1101 et seq.), which governs private construction projects. On private projects, subcontractors and suppliers must comply with the Construction Lien Act's notice and filing requirements to secure construction lien rights against the property. On public projects governed by MI Comp Laws § 129.201, the remedies run against the payment bond rather than the property, and the notice requirements are different. The most critical difference is Michigan's 30-day preliminary notice requirement for public project payment bond claims, which requires notice early in the project rather than after the work is complete.
Frequently Asked Questions About Michigan Contract Bonds
Under MI Comp Laws § 129.201 et seq., both performance and payment bonds are required on all Michigan public construction projects exceeding $50,000. Each bond must be in an amount equal to the contract price. These requirements apply to contracts awarded by all Michigan governmental entities, including the state, counties, cities, villages, townships, school districts, community colleges, and public universities.
Yes, for residential contractors. Michigan requires a $10,000 residential builder's license bond for residential builders and maintenance and alteration contractors through the Department of Licensing and Regulatory Affairs (LARA). This bond protects homeowners against financial loss caused by the contractor's failure to comply with Michigan's Residential Builders Act. Commercial and industrial general contractors are not required to post a statewide license bond in Michigan, though some municipalities have local licensing and bonding requirements.
Michigan's notice requirement is unique and critically important. Under MI Comp Laws § 129.207, claimants who do not have a direct contract with the bonded contractor must serve written notice on both the contractor and the governmental entity within 30 days after first furnishing labor or materials. This is an early notice requirement — it must be given at the beginning of the project, not after the work is complete. This differs from many other states that require notice after last furnishing. Failure to give timely notice can result in the loss of payment bond rights.
Under MI Comp Laws § 129.211, no action may be brought on a public project payment bond after one year from the date of final completion and acceptance of the project by the governmental entity. This is different from many states that measure the deadline from the claimant's last furnishing date. In Michigan, the clock starts running from the overall project completion date, which means claimants must monitor the project's status to ensure they do not miss the filing deadline.
No. Construction liens (Michigan's equivalent of mechanic's liens) cannot be filed against public property. The Michigan Construction Lien Act (MCL § 570.1101 et seq.) applies only to private construction projects. On public projects, the payment bond required under MI Comp Laws § 129.201 serves as the substitute for construction lien rights. If you are a subcontractor or supplier who has not been paid on a Michigan public project, your remedy is to make a claim against the contractor's payment bond.
Michigan 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 depends on the contractor's credit scores, financial statements (balance sheet strength, working capital, net worth), years of construction experience, 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 Michigan contractor bonding a $1,000,000 public project might pay $10,000 to $25,000 in combined performance and payment bond premiums.
The Homeowner Construction Lien Recovery Fund is a state-administered fund that provides an additional layer of protection for Michigan homeowners beyond the residential builder's license bond. Administered by LARA, this fund can compensate homeowners who suffer financial losses due to a licensed residential builder's failure to pay subcontractors (which results in construction liens being placed on the homeowner's property), as well as other covered claims. The fund operates separately from the $10,000 license bond and has its own application process and eligibility requirements.
