New Hampshire Contractor Bond— Municipal & Public Works Bonds

New Hampshire does not require a state-level contractor license bond -- general contractors are not licensed at the state level. However, over 30 municipalities enforce independent bonding requirements ranging from $4,000 to $125,000, and the state's Little Miller Act (RSA 447:16-18) mandates performance and payment bonds on public works contracts. Whether you need a municipal bond or public project bonding, we can help. Businesses in New Hampshire that also require a New Hampshire auto dealer bond can apply for both at once. Contractors working across the border should check Vermont contractor bond requirements as well.

Official New Hampshire Requirements

"Every person who enters into a formal contract with the state or any political subdivision thereof for the construction, alteration or repair of any public building or public work... shall furnish a performance bond and also a payment bond."
New Hampshire Revised Statutes Annotated, RSA 447:16 • RSA 447:16-18 (Little Miller Act)

No State-Level Contractor License Bond in NH

Unlike many states, New Hampshire does not license general contractors at the state level and has no statewide contractor license bond requirement. The Office of Professional Licensure and Certification (OPLC) licenses electricians, plumbers, and HVAC technicians, but none of these trade licenses require a surety bond. Contractor bonding in New Hampshire is driven by two separate systems:

Municipal Bonds
$4,000-$125,000
30+ cities/towns with independent requirements
Public Works Bonds (RSA 447)
100% of Contract
Performance + payment bonds required

No Lien Rights on Public Projects: Why Payment Bonds Are Critical

Subcontractors on unbonded public work have almost no recourse for nonpayment

On private construction projects in New Hampshire, subcontractors who are not paid can file a mechanics lien against the property under RSA 447:1-15. This lien attaches to the real property and provides significant leverage for collecting unpaid debts.

On public projects, however, this remedy does not exist -- you cannot place a lien on government-owned property. The payment bond required under RSA 447:16-18 serves as the substitute protection. If a general contractor fails to pay subcontractors on a bonded public project, those subcontractors file claims against the payment bond rather than the property.

This distinction is critical for subcontractors evaluating whether to work on public projects. If the general contractor does not carry a payment bond (because the contract falls below the $75,000 state or $125,000 municipal threshold), subcontractors have limited recourse for non-payment. Learn more about payment bonds on our payment bonds page.

From Bid Documents to Bond Filing: The Public Works Process

Five steps to securing your RSA 447 performance and payment bonds

1

Identify Bond Requirements

Review the project bid documents or RFP to determine if performance and payment bonds are required. State contracts at $75,000+ and municipal contracts at $125,000+ trigger mandatory bonding under RSA 447:16-18.

2

Gather Financial Documentation

Prepare your business financial statements, work history, equipment schedule, and bank references. Larger contracts require more thorough underwriting by the surety company.

3

Apply for Your Bonds

Submit your application through a licensed surety bond provider. Performance bonds guarantee project completion; payment bonds guarantee payment to subcontractors and suppliers.

4

Submit Bonds with Contract

Once approved, provide your performance and payment bonds (each at 100% of contract value) to the contracting authority. Bonds must be from a Treasury-listed surety company.

5

Maintain Bond Through Completion

Your bonds remain active for the duration of the project and applicable warranty period. The surety company may require updated financials for multi-year projects.

What Your NH Municipal Bond Will Cost

Credit score is the biggest factor -- here is the range for a $5,000 bond

Public works performance/payment bonds for larger contracts cost 1-3% of the contract value. Use our contractor bond calculator for a personalized estimate.

New Hampshire Contractor Bond FAQs

Common New Hampshire contractor bond questions

Does New Hampshire require a state contractor license bond?
No. New Hampshire does not have a state-level contractor license bond requirement. Unlike states such as California or Florida, NH does not license general contractors at the state level at all. However, individual municipalities across the state have their own bonding requirements, and public works projects require performance and payment bonds under the Little Miller Act (RSA 447:16-18). If you work in multiple NH municipalities, you may need separate bonds for each jurisdiction.
What is the New Hampshire Little Miller Act (RSA 447:16-18)?
The New Hampshire Little Miller Act, codified in RSA 447:16-18, requires contractors on public works projects to provide performance and payment bonds. For state contracts of $75,000 or more, both bonds must equal 100% of the contract value. For municipal contracts of $125,000 or more, the same 100% bonding requirement applies. These bonds protect the government entity and subcontractors/suppliers from contractor default or non-payment.
Which NH municipalities require contractor bonds?
Over 30 New Hampshire cities and towns have independent contractor bonding requirements. Manchester requires a $5,000 bond for highway and street work. Salem requires bonds and insurance through its Engineering Division. Nashua, Concord, Dover, and many other municipalities have their own requirements ranging from $4,000 to $125,000. There is no centralized state registry -- you must contact each municipality directly to verify current bond requirements before bidding on work.
Do NH electricians, plumbers, or HVAC contractors need bonds?
No. While the New Hampshire Office of Professional Licensure and Certification (OPLC) licenses electricians, plumbers, and HVAC technicians at the state level, none of these trade licenses require a surety bond. Licensing requirements focus on examination, experience, and continuing education rather than bonding. However, these tradespeople may still need bonds for specific municipal work or public works contracts.
How much does a New Hampshire contractor bond cost?
New Hampshire contractor bond costs depend on the bond amount required and your credit profile. For municipal bonds ($4,000-$125,000 range), expect to pay 1-5% of the bond amount annually. A $5,000 Manchester highway bond might cost $50-$250 per year. Public works performance and payment bonds for larger contracts typically cost 1-3% of the contract value. For a deeper look at pricing, see our surety bond cost guide at /surety-bond-cost/.
How do I get bonded for a New Hampshire public works project?
To get bonded for an NH public works project: (1) Identify the specific bond requirements from the project bid documents, (2) Gather your financial statements, work history, and credit information, (3) Apply through a licensed surety bond provider, (4) Receive your performance and payment bonds matching 100% of the contract value, (5) Submit bonds with your bid or upon contract award. Most bonds can be issued within 1-5 business days depending on contract size and your qualifications.
Can I transfer my New Hampshire contractor bond to another state?
No. Each state has its own bonding requirements and obligees. A New Hampshire municipal bond is payable to that specific municipality and cannot be used in Vermont, Massachusetts, or Maine. If you work across state lines, you need separate bonds in each state. However, applying through a single surety provider simplifies the process -- we can issue bonds for multiple states from one application.
What is the difference between a New Hampshire contractor bond and a performance bond?
A municipal contractor bond (also called a license bond) is required to obtain and maintain your contractor license in an NH municipality. It guarantees compliance with local codes and regulations. A performance bond, required under RSA 447:16-18 for public works contracts, guarantees that you will complete a specific project according to the contract terms. You may need both simultaneously -- the license bond for your municipal registration and a performance bond for each qualifying public project.
