New Hampshire prevailing wage requirements affect every GC and estimator bidding public works projects—and rates change annually. Understanding the 2026 rates, classification nuances, and compliance requirements is critical to avoiding underbids and penalties.
New Hampshire's prevailing wage landscape presents a unique challenge for estimators: the state has no prevailing wage law for state-funded projects, but federal Davis-Bacon requirements apply to any project receiving federal dollars. You estimate under two different regimes depending on funding source. Getting it wrong compresses your margin by 15% or more before breaking ground. For a $5 million public works project, that's $750,000 in labor cost requiring precision.
Labor represents 30–50% of total project cost on most commercial builds. When prevailing wage applies, those rates run 20–40% higher than open-shop market rates. Ironwork, electrical, and HVAC trades show the steepest premiums. A prevailing wage electrician costs $58/hour plus $32 in fringes. Your standard market rate runs $42 all-in. That's $48 per man-hour difference. Underestimating headcount or misclassifying workers turns winning bids into losses.
New Hampshire has no state prevailing wage law for public works projects. This distinguishes it from Massachusetts, Connecticut, and Vermont, where state-level prevailing wage applies to publicly funded construction. Contractors on federally funded projects must comply with the Davis-Bacon Act and related federal wage determinations.
Federal Davis-Bacon requirements kick in when a project receives more than $2,000 in federal funding. Construction, alteration, or repair of public buildings or public works all trigger compliance. This threshold is low. Even small federal grants activate full prevailing wage requirements. The Davis-Bacon Act mandates contractors and subcontractors pay workers no less than locally prevailing wages and fringe benefits for corresponding work on similar projects in the area.
The Department of Labor determines prevailing wage rates based on two sources: collective bargaining agreements (union rates) or wage surveys in each locality. For New Hampshire, these rates appear as wage determinations organized by county and trade classification. General building construction differs from heavy construction or highway project determinations. Estimators must match the correct WD number to project type and location.
Non-compliance penalties are severe and material. Contract termination is standard. Debarment from future federal contracts lasts up to three years. Progress payments get withheld. Back wages plus liquidated damages become your liability. The DOL can require certified payroll audits spanning years. For preconstruction teams, prevailing wage compliance is not just a labor cost issue—it's a risk management and bonding capacity issue.
Common project types that trigger federal prevailing wage in New Hampshire include:
Confirm funding sources during the proposal stage. Mixed-funding projects combine state, local, and federal dollars. Careful parsing is required. Only the portion funded by federal dollars may require prevailing wage. In practice, most owners apply prevailing wage to the entire project. This simplifies compliance and payroll administration.
Prevailing wage rates for New Hampshire in 2026 are governed by Davis-Bacon wage determinations issued by the U.S. Department of Labor. These determinations specify hourly base wages and fringe benefit rates. Dozens of trade classifications are included and organized by county or multi-county regions.
Davis-Bacon wage determinations for New Hampshire are organized by county groups and construction type. WD NH20260022 covers general building construction in Hillsborough and Rockingham counties. Separate determinations apply to heavy and highway work statewide. Rates update periodically. New surveys trigger updates. Union collective bargaining agreement renegotiations trigger updates as well.
Union prevailing wage rates reflect all changes over time. Wage rates typically remain in effect until a new survey is conducted. Some rates stay static for 12–24 months. Others—particularly in high-activity trades—see annual adjustments of 3–5%. Electrical and plumbing rates shift most frequently.
Sample 2026 prevailing wage rates for select trades in Southern New Hampshire are based on recent DOL determinations:
These rates represent total compensation. Distinguish between base wage and fringe benefits. Fringe benefits can be paid as cash wages or as bona fide benefits. Health insurance, pension contributions, and training funds qualify as benefits. Your payment method affects payroll tax calculations. Workers' compensation premiums and general liability insurance costs shift based on your choice.
If you pay a $34.50 fringe as cash, add 7.65% FICA. State and federal unemployment taxes apply. Workers' comp adds 8–15% depending on trade classification. That $34.50 becomes $38–40 in true cost. Pay it as benefits instead. Those taxes don't apply to the fringe portion. You must administer qualifying benefit plans. Document contributions for DOL audits.
Davis-Bacon wage determinations list dozens of classifications within each trade. Determining which classification applies to your crew is critical for margin protection. A carpenter, millwright earns a different rate than a carpenter, form builder. Carpenter, acoustical ceiling installer rates differ as well. Misclassification—intentional or accidental—is one of the most common compliance violations.
Each wage determination includes detailed scope of work descriptions for every classification. Examples include:
