Prevailing wage

Connecticut prevailing wage and certified payroll rules

Connecticut's prevailing wage law (C.G.S. 31-53) covers state and municipal public works when the whole project reaches $1 million for new construction or $100,000 for remodeling and repair. Rates come from the Department of Labor, reset every July 1, and certified payroll goes to the contracting agency monthly.

Yes, Connecticut has its own prevailing wage law, and it is stricter on paperwork than most. Section 31-53 of the Connecticut General Statutes covers construction, remodeling, and repair of public works for the state, its agents, and every town, city, and school district. The trigger is the combined total cost of all work by all contractors and subcontractors: $1 million or more for new construction, $100,000 or more for remodeling, refinishing, refurbishing, rehabilitation, alteration, or repair. Contractors file a certified payroll with a signed statement of compliance every month, and knowingly filing a false one is a felony.

Which Connecticut projects are covered

The dollar test is project-wide, not per contract. A town that splits a $1.3 million library addition into a $700,000 general contract and a $600,000 site package still has a covered project, because the statute counts the combined total cost of all work by all contractors and subcontractors. Before awarding any contract, purchase order, or bid package, the public agency has to certify the total dollar amount of the project to the Labor Commissioner. After award, the contractor certifies under oath the pay scale it and its subs will use.

  • New construction: covered when the combined total cost or total bond authorization reaches $1,000,000.
  • Remodeling, refinishing, refurbishing, rehabilitation, alteration, or repair: covered at $100,000.
  • State highways and bridges: Section 31-54 carries its own wage requirement for state highway work.
  • Other funding streams: Section 31-53c covers certain projects funded by the Department of Economic and Community Development, and 31-53d covers some renewable energy and hydrogen projects.

The rules moved recently. Public Acts 25-168 and 25-174 took effect July 1, 2025, and the Department of Labor says they changed coverage of certain off-site fabrication work and DECD-funded projects, and confirmed that all prevailing wage projects are subject to the annual July 1 rate adjustment. If you fabricate in your own shop for a public job, ask the agency or the department how the 2025 changes apply before you price it. The department will also issue a coverage determination letter for a specific project on request by email.

How Connecticut sets rates and where to find them

Connecticut rates are set town by town. The Labor Commissioner adopts the hourly wage and the fringe benefit contributions (health, pension, annuity, and apprenticeship funds) from the collective bargaining agreements for the same trade in the town where the project is built. Where more than one agreement covers a trade, the agreement of historical jurisdiction wins. Where no agreement exists for that trade in that town, the department uses the federal Davis-Bacon determination instead.

The Department of Labor posts the schedules on its prevailing wage page in three sets: Building, Heavy/Highway, and Residential, along with an Important Information sheet and footnotes. The department warns that rates can change during the year and that a project going out to bid should use a bid package with current rates. The public agency is supposed to contact the Labor Commissioner 10 to 20 days before advertising to get the right schedule into the bid documents.

The July 1 adjustment

Here is the rule that catches out-of-state contractors. Under Section 31-55a, every contractor on a covered job must contact the Labor Commissioner on or before July 1 of each year for the life of the contract and raise wages and fringe contributions to the new rates effective that July 1. Say you win a $2.4 million school roof and HVAC job in February and the work runs into October. Your bid rates are good through June 30, and every hour after that is paid at the new schedule. Build the July bump into your bid, because the contract price does not move with it.

If you are not signed to a fund, you still owe the fringe. The statute says a contractor with no obligation to pay into an employee welfare fund must pay the fringe amount for each worker's classification as cash wages on every payday. See how to calculate fringe benefit credits for the math.

Connecticut certified payroll requirements

Every employer on a covered job keeps wage and hour records by worker and classification, and submits a certified payroll to the contracting agency every month. The department's form is the Payroll Certification for Public Works Projects, and the statute allows records to be kept and sent electronically, by mail, email, or another method the agency accepts. The signed statement that goes with it says:

  1. The records are correct.
  2. Each worker was paid at least the prevailing wage and fringe set by the Labor Commissioner and the contract.
  3. The employer complied with the prevailing wage sections.
  4. Each worker is covered by workers' compensation, shown by listing the carrier, policy number, and effective and expiration dates.
  5. The employer receives no kickbacks from any employee or welfare fund.
  6. The employer knows that filing a certified payroll it knows to be false is a class D felony.

Two details matter for general contractors. A GC may rely on a lower-tier sub's certification, but not if it knows the certification is false. And Connecticut treats certified payrolls as public records, so anyone can ask to inspect and copy them. Collect payroll from every sub on a fixed day each month; our guide on collecting certified payroll from subcontractors covers a routine that holds up.

10-hour OSHA proof

Section 31-53b requires each contractor to furnish proof, with the certified payroll for the first week each employee starts on the project, that the worker has completed at least a 10-hour OSHA-approved construction safety and health course. Keep a copy of every card in the job file before the worker's first day, not after.

Penalties for Connecticut prevailing wage violations

  • Underpayment: a contractor or sub that knowingly or wilfully pays below the prevailing rate or skips fringe contributions can be cited and fined $5,000 for each offense.
  • Violator list and debarment: the commissioner keeps a list of violators and settlements for the preceding three calendar years, reviews it every May 1, and must refer for debarment any contractor whose settlements in that period exceed $50,000 in back wages or fringe benefits, or $50,000 in penalties.
  • Agency remedies: the state or town can terminate the contractor's right to proceed and charge the excess cost to the contractor and its surety, or withhold payment.
  • Certified payroll: filing one you know is false is a class D felony with a fine up to $5,000, prison up to five years, or both.

How Connecticut differs from Davis-Bacon

Federal Davis-Bacon covers federally funded or assisted contracts over $2,000 and requires certified payroll weekly, usually on the optional WH-347 form (see Form WH-347). Connecticut's thresholds are far higher, its rates come from local union agreements town by town, its payroll is monthly, the statement of compliance adds workers' comp and felony language, and rates step up every July 1 during the contract. A municipal project with federal grant money can carry both sets of rules, so ask the agency up front which schedules apply and whether it wants weekly federal payrolls in addition to the monthly state filing.

Connecticut work also touches the state's other contractor rules. Check the Connecticut contractor license requirements, Connecticut mechanics lien deadlines, and Connecticut prompt payment rules for public jobs.
