Prevailing Wage Rules for New Hampshire Contractors
Prevailing wage rules govern the minimum hourly compensation — including wages and fringe benefits — that contractors must pay workers on covered public construction projects. In New Hampshire, the legal framework differs substantially from the federal Davis-Bacon Act and from the prevailing wage statutes enacted by states such as Massachusetts or Vermont. Understanding where New Hampshire's rules apply, where federal law supersedes them, and which projects fall outside both frameworks is essential for contractors bidding on public work in the state.
Definition and scope
Prevailing wage, in the context of public construction, refers to the rate of pay — base wage plus any applicable fringe benefits — determined to be standard for a given trade or occupation in a specific geographic area. At the federal level, the Davis-Bacon Act (40 U.S.C. §§ 3141–3148) mandates these rates on federally funded construction contracts exceeding $2,000.
New Hampshire does not maintain a standalone state prevailing wage law applicable to all public construction. The state legislature has not enacted a "Little Davis-Bacon" statute of the type found in roughly 32 other states (U.S. Department of Labor, Wage and Hour Division). This structural fact distinguishes New Hampshire's regulatory landscape from neighboring states and directly affects how contractors operating across state lines must classify their wage obligations.
Scope boundary: The prevailing wage obligations described on this page apply to construction projects in New Hampshire that receive direct federal funding or federally assisted financing triggering Davis-Bacon coverage. State-only funded public construction in New Hampshire does not carry a state-mandated prevailing wage requirement. This page does not address prevailing wage law in Massachusetts, Vermont, or Maine, nor does it cover private construction projects. For a broader overview of the regulatory environment affecting contractors in the state, see New Hampshire Contractor Regulatory Agencies.
How it works
When a New Hampshire public construction project receives federal funding above the Davis-Bacon threshold of $2,000, the contracting federal agency is required to include wage determinations in the bid solicitation. These determinations are published through the SAM.gov Wage Determinations portal and specify minimum wages by trade classification for the applicable county.
The mechanism operates through the following structured sequence:
- Federal agency or program grantee identifies federal funding involvement and determines whether Davis-Bacon applies to the contract type (building construction, heavy construction, highway construction, or residential construction — each carries separate wage schedules).
- Wage determination selection — the appropriate determination is pulled from SAM.gov using the state (New Hampshire) and county as geographic parameters.
- Incorporation into contract documents — the applicable wage determination is embedded in the solicitation and becomes a binding contract term.
- Payroll certification — contractors and subcontractors submit certified payrolls weekly using Department of Labor Form WH-347 or equivalent software output.
- Compliance monitoring — the contracting agency or designated compliance officer reviews payroll records; the U.S. Department of Labor Wage and Hour Division retains investigative authority.
- Withholding and debarment — non-compliant contractors face withholding of contract funds; willful violations can result in debarment from federal contracts for up to 3 years under the Copeland Anti-Kickback Act (18 U.S.C. § 874).
Fringe benefits — including health insurance, pension contributions, and vacation pay — may satisfy a portion of the prevailing wage obligation, reducing the cash wage component. Contractors electing to pay the full prevailing rate in cash rather than through bona fide fringe benefit plans must pay the combined wage-plus-fringe rate entirely as wages.
For contractors navigating the parallel obligations of worker classification alongside wage compliance, New Hampshire Contractor Worker Classification addresses the independent contractor versus employee distinction that bears directly on payroll compliance.
Common scenarios
Federally funded municipal building project: A New Hampshire municipality receives a Community Development Block Grant (CDBG) for renovation of a public community center. CDBG-funded construction triggers Davis-Bacon and Related Acts requirements. The municipality must incorporate the appropriate wage determination — typically the "building construction" schedule for the relevant county — into all prime and subcontractor agreements.
State highway project with federal-aid funds: Projects funded through the Federal Highway Administration (FHWA) Federal-Aid Highway Program are subject to Davis-Bacon under the Federal-Aid Highway Acts. Contractors bidding on New Hampshire Department of Transportation (NHDOT) federally assisted highway work must comply with highway construction wage determinations.
State-funded school construction with no federal dollars: A New Hampshire school district uses a state bond with no direct federal funding. Because New Hampshire has no state prevailing wage statute, no prevailing wage obligation attaches to this project. This contrast with federally funded work is the central classification boundary contractors must evaluate at the bid stage.
Mixed-funding project: When a project combines state general funds with a federal grant covering even a portion of construction costs, the entire contract typically falls under Davis-Bacon if the federal contribution meets or exceeds the triggering threshold and the funding streams cannot be separated by discrete contract packages. Contractors should consult the funding agency's specific program guidance for blended-funding treatment.
Decision boundaries
The threshold determination in any New Hampshire public construction scenario is whether federal dollars are involved. The table-level classification logic breaks down as follows:
| Funding Source | State Prevailing Wage Applies? | Federal Davis-Bacon Applies? |
|---|---|---|
| Federal funding only | No (no NH statute) | Yes, if contract ≥ $2,000 |
| State funding only | No | No |
| Mixed federal + state | No | Yes, per federal program rules |
| Local funding only | No | No |
A secondary boundary involves the four Davis-Bacon construction categories — building, residential, highway, and heavy — each assigned separate wage schedules. Misclassifying a project type (e.g., treating a water treatment plant as "building" rather than "heavy") results in application of the wrong wage determination, which constitutes a compliance violation regardless of whether underpayment occurred.
Subcontractors are bound to the same wage determinations as prime contractors. A prime contractor cannot legally absolve itself of Davis-Bacon obligations by delegating work to subcontractors without passing through the wage determination requirements. This subcontractor flow-down obligation is documented in the contract clauses required by 29 CFR Part 5.
For contractors assessing the full spectrum of public project obligations alongside prevailing wage compliance, New Hampshire Public Works Contractor Requirements and New Hampshire Contractor Bid Process describe the additional qualification and procedural standards that govern public contract participation. Licensing status — particularly relevant for specialty trades on covered projects — is detailed at New Hampshire Contractor License Requirements.
