Prevailing Wage Delaware: A Contractor's Guide to Rates, Requirements, and Certified Payroll

Last Updated: June 2026

Delaware may be the second smallest state in the country, but its public construction pipeline keeps contractors busy, from school district buildings and DelDOT highway and bridge work to Port of Wilmington upgrades and state facility projects. Whenever state dollars fund that work, Delaware's own prevailing wage law applies, and it operates separately from the federal Davis-Bacon Act.

Delaware maintains its prevailing wage requirements under 29 Del. C. § 6960, administered by the Delaware Department of Labor, Division of Industrial Affairs. The law sets county-specific wage floors for laborers and mechanics on state-funded public works, requires weekly certified payroll, and carries real penalties for getting it wrong.

This guide covers which projects are covered and at what dollar thresholds, how the state sets county rates, the annual determination cycle, certified payroll and apprenticeship rules, the penalty structure, and a phase-by-phase compliance checklist.

Delaware Prevailing Wage Basics

Key Takeaways

  • Delaware has its own prevailing wage law (29 Del. C. § 6960), administered by the DOL Division of Industrial Affairs.
  • State-funded public works trigger Delaware rates. Federally funded work triggers the Davis-Bacon Act.
  • Prevailing wage applies to new construction over $500,000 and to alteration or repair work over $45,000.
  • Rates are set by county (New Castle, Kent, and Sussex) and published annually on or before March 15.
  • Certified payroll must be submitted weekly, and the DOL retains it for six months.
  • Civil penalties run $1,000 to $5,000 per violation, with up to three years of debarment from public works.

In Delaware, the prevailing wage is the combination of a base hourly rate and bona fide fringe benefits paid to the majority of workers in a specific trade within a specific county. The Delaware Department of Labor, Division of Industrial Affairs sets these rates and enforces payment on state-funded construction, under the authority of 29 Del. C. § 6960.

The purpose is straightforward: to protect local wage standards so that taxpayer-funded construction does not undercut the going rate for skilled trades in each county. Delaware organizes its determinations into three construction categories: Building, Highway, and Heavy.

 

What Qualifies as a Public Works Project in Delaware?

Delaware law defines a public works project as the construction, reconstruction, demolition, alteration, repair, or maintenance of a public building or work that is paid for with funds from the State of Delaware, a state agency, a public school district, or the federal government.

Two dollar thresholds determine whether prevailing wage provisions must be written into the contract:

  • New construction (including painting and decorating): projects over $500,000.
  • Alteration, repair, renovation, rehabilitation, demolition, or reconstruction: projects over $45,000.

Because the funding source decides which law governs, that is the first question to settle on any public project. State funds point you to Delaware's determination. Federal funds point you to Davis-Bacon.

How Does Delaware Prevailing Wage Compare to Federal Davis-Bacon?

Delaware's state prevailing wage law and the federal Davis-Bacon Act both set wage floors for public construction, but they apply to different funding sources and operate independently.

Delaware's law applies to projects funded by the state or its subdivisions. The federal Davis-Bacon Act applies to federally funded or assisted construction contracts over $2,000. When a project carries both state and federal dollars, contractors may need to satisfy both frameworks and pay the higher applicable rate. For any mixed-funding project, confirm your specific obligations with the contracting agency before work begins.

Rate-setting differs between the two as well. Delaware ties its rates to local collective bargaining agreements where those rates prevail, and falls back on its own annual survey where they do not. Federal Davis-Bacon rates are set by the U.S. Department of Labor through separate wage surveys and published through SAM.gov wage determinations. Because the two can produce different numbers for the same trade and county, pulling the correct determination for your funding source is essential.

For a deeper look at how these frameworks differ, see our guide on Understanding the Difference Between State and Federal Prevailing Wage Laws.

 

How Are Delaware Prevailing Wage Rates Determined?

Delaware sets prevailing wage rates by tying them to collective bargaining agreements. When a labor organization's collectively bargained rate has prevailed for a particular trade in a particular county for four consecutive years, that rate becomes the prevailing wage. When no collective bargaining rate applies, the prevailing wage is the highest rate of the four years, or the Department uses the rate established by its annual prevailing wage survey.

Every rate has two components: a base hourly rate and a fringe benefit amount. Both are published together, and both count toward the total wage obligation.

To put the right rate on a worker, you need the determination that matches the project's county, trade classification, and construction category. For help interpreting one, see our guide on how to read a wage determination.

County Rates: New Castle, Kent, and Sussex

Delaware publishes rates by county, and the same trade can carry a different rate in New Castle, Kent, and Sussex. As an illustration of the spread, the state's highest prevailing wage applies to elevator constructors in building construction in New Castle, while one of the lowest applies to certain roofing classifications in Sussex.

For contractors working across county lines, that variation matters at bid time. Using a New Castle rate on a Sussex project, or the reverse, can leave you either underbidding or out of compliance. Always pull the current determination from the Delaware DOL for the specific county where the work is performed.

The Annual Determination and Survey Cycle

Delaware refreshes its rates on a fixed annual schedule:

  • The Department mails survey forms to contractors and interested parties at the end of the calendar year.
  • Completed surveys are due back in early February.
  • Contractors may submit opinions for reconsideration of rates around mid-February.
  • On or before March 15, the Department publishes its annual Prevailing Wage Determination, valid for one year or until amended.

Once published, the determination holds for the cycle. The Department also offers electronic survey reporting through its online labor and licensing environment (OLLE).

Delaware Contractor Licensing and Registration

Two registration requirements sit alongside prevailing wage compliance. Contractors bidding on jobs over $50,000 must apply for a license, and construction businesses must register with the Delaware Department of Labor Office of Contractor Registration before beginning work in the state. Confirm both are active before you bid.

Apprentices and Prevailing Wage in Delaware

Apprentices can be paid apprentice rates on Delaware public works, but only under specific conditions. An apprentice must be indentured and employed in a bona fide apprenticeship program, and individually registered with the Delaware Department of Labor by the program sponsor. Any apprentice or trainee who is not registered must be paid the full prevailing wage rate for the classification of work they actually performed.

Delaware apprenticeships generally run about four years, or 8,000 hours of on-the-job training, with a minimum of 144 hours of related classroom instruction per year. Completing the program qualifies the worker for journeyperson status.

Apprentice-to-journeyworker ratios are a frequent source of compliance questions on prevailing wage projects. For more on how those ratios work, see our guide on apprenticeship ratios and prevailing wage requirements.

Certified Payroll Reporting in Delaware

Delaware does not publish its own uniquely numbered certified payroll form. Instead, contractors submit sworn weekly payroll in the federal Form WH-347 format, which keeps reporting consistent for contractors who also handle Davis-Bacon work. The key distinction is where the report goes: on federally funded projects, certified payroll follows the federal process, while on state-funded projects, the sworn payroll is submitted to the Delaware Department of Labor.

One requirement that is specific to Delaware sits alongside the payroll report itself: a daily task log for each worker, described in the recordkeeping section below. Together, the weekly certified payroll and the daily log form the backbone of a Delaware compliance file.

 

What Goes on a Delaware Certified Payroll Report?

Each certified payroll report should capture:

  • Worker name and trade classification (matching the wage determination classifications)
  • Daily and total weekly hours worked on the covered project
  • Base hourly rate and fringe benefit rate
  • Gross wages earned
  • Itemized deductions
  • Net wages paid
  • A signed statement of compliance attesting to the accuracy of the report

Worker misclassification is the single most common and most expensive certified payroll error. Classification must reflect the work actually performed, not a job title or the rate a contractor budgeted for.

Fringe Benefits & Overtime

Delaware recognizes a specific set of fringe benefits toward the prevailing wage obligation: health, welfare, retirement, vacation, holiday, sick leave, and education benefits relating to apprenticeship and training programs. Contractors can satisfy the fringe obligation by providing actual benefits, paying the cash equivalent, or using a combination of the two, as long as total compensation meets the full base-plus-fringe requirement.

For overtime, hours worked beyond 40 in a work week are paid at one and a half times the applicable base prevailing wage rate, plus the fringe benefit for the task actually performed. For a fuller breakdown of how fringe works, see our easy explanation of fringe benefits.

 

Posting & Recordkeeping Requirements

Contractors must post the applicable wage scale in a prominent, easily accessible place at the job site. Delaware's prevailing wage regulations also require a daily log for each worker that lists, in general terms, the tasks performed and the time spent on each (for example, "hung drywall" or "wired lighting fixtures"). This task log supports accurate classification and is exactly the kind of record an investigator will ask to see.

 

Delaware Prevailing Wage Violations and Penalties

Delaware enforces prevailing wage through the Division of Industrial Affairs. When the Department finds an employer has not paid the required rates, it notifies the employer by certified mail and allows 15 days to come into compliance before escalating. The consequences stack quickly:

Any employer who knowingly fails to pay prevailing wage, submit payroll reports, or post the required notice faces a civil penalty of $1,000 to $5,000 for each violation.

Full payment of underpaid wages and fringe benefits owed to affected workers.

 The Department may direct that accrued contract payments be withheld to cover the difference owed to workers.

If an employer fails to comply within 15 days of the certified-mail notice, the Secretary may terminate the employer's right to proceed under the contract, with the employer liable for resulting damages.

Contractors adjudicated in violation can be barred from bidding on or being awarded public works in Delaware for three years from the date of judgment, and Delaware maintains a public debarment list.

 

The takeaway for contractors is simple: the cost of a single misclassification or a missed payroll submission can far exceed the cost of getting the process right from day one. For a look at the errors investigators flag most often, see our guide on common prevailing wage contractor errors.

Delaware Prevailing Wage Compliance by Project Phase

Prevailing wage compliance touches every stage of a Delaware public works project. Here is what to have in place at each phase.

Pre-Bid Phase

  • Confirm the funding source: state funds mean Delaware's law, federal funds mean Davis-Bacon, and mixed funding may mean both.
  • Verify the project meets the applicable threshold ($500,000 new construction or $45,000 alteration and repair).
  • Confirm your contractor license (for jobs over $50,000) and DOL contractor registration are active.
  • Pull the current determination for the project's county and trade classifications, and build base plus fringe into your estimate.

During Project Execution
  • Post the applicable wage scale conspicuously at the job site.
  • Classify every worker by the duties actually performed, not by title.
  • Maintain the required daily task log for each worker.
  • Monitor subcontractor compliance, since responsibility for the project's certified payroll flows up to the prime contractor.

Active Project and Close-Out

    • Submit sworn, certified payroll weekly in the WH-347 format.
    • Watch for any amended determination published during the project cycle.
    • Run an internal payroll audit before close-out to catch and correct discrepancies before the Department does.

 

Simplify Delaware Prevailing Wage Compliance

Delaware's county-specific rates, weekly certified payroll, apprenticeship rules, and steep penalties make compliance a moving target, especially for contractors managing multiple projects or working across all three counties.

Points North gives you two ways to stay ahead of it. WageIQ automates your most complex prevailing wage and fringe calculations before payroll runs, applying the correct county rate and classification to every worker and integrating with the payroll system you already use. For contractors who would rather hand the work off entirely, Managed Services handles the compliance process from start to finish, which is especially valuable for firms new to prevailing wage or juggling complex, multi-site projects.

Frequently Asked Questions

The Delaware prevailing wage is the base hourly rate plus fringe benefits that the Department of Labor requires on state-funded public works. Rates are set by county and trade classification under 29 Del. C. § 6960 and published in an annual determination.

The Delaware Department of Labor, Division of Industrial Affairs sets and enforces prevailing wage rates. Rates are tied to local collective bargaining agreements where they prevail, and to the Department's annual survey where they do not.

Prevailing wage applies to new construction projects over $500,000 and to alteration, repair, renovation, demolition, or reconstruction projects over $45,000, when the work is funded in whole or in part by the State of Delaware.

Not for state-funded work. Delaware uses its own determination for state-funded projects. Federally funded projects follow the Davis-Bacon Act, and the two rate sets can differ, so contractors must apply the correct one based on the funding source.

Yes. Contractors on covered public works must furnish sworn certified payroll weekly. Delaware accepts the federal WH-347 format, and the Department of Labor retains submitted payroll for six months.

The Department publishes a new Prevailing Wage Determination on or before March 15 each year, valid for one year or until amended.
