9.3 Prevailing Wage and Public Work
Key Takeaways
- Maryland's prevailing wage law covers state-funded public works construction contracts valued at $250,000 or more with state funding of 25 percent or more, including school construction
- Rates are set by the Commissioner of Labor and Industry by trade classification and locality, and include a basic hourly rate plus fringe benefits payable in benefits or cash
- Workers must be paid for the classification of work they actually perform, and every contractor and subcontractor on a covered project files weekly certified payrolls
- The federal Davis-Bacon Act applies to federal construction contracts over $2,000 and also requires weekly certified payrolls; mixed-funding projects can trigger both laws
- Private home improvement work is almost never covered, but the trigger — public funding plus contract value — is still tested
What Maryland's Prevailing Wage Law Requires
Prevailing wage laws take labor cost out of the competition on taxpayer-funded construction: every bidder must pay the same locally prevailing rates, so contracts are won on efficiency and management rather than on who can squeeze wages hardest. Maryland's law lives in the State Finance and Procurement Article, Title 17, Subtitle 2, and is administered by the Prevailing Wage Unit of the Division of Labor and Industry.
The Coverage Trigger
According to the Maryland Department of Labor's Prevailing Wage Unit, the law applies to state or political-subdivision construction contracts — including school construction — where the contract value is $250,000 or more with state funding of 25 percent or more. Two numbers, and the exam tests both: the dollar threshold and the state-funding percentage. Subcontractors on a covered project are covered just like the prime — you cannot escape the law by taking a small slice of a large covered contract.
How Rates Are Set
The Commissioner of Labor and Industry surveys the market and issues hourly prevailing rates by trade classification (carpenter, electrician, laborer, and so on) and by locality, because rates differ across Maryland's regions. Each covered project gets a wage determination that becomes part of the contract documents. The prevailing rate has two parts: a basic hourly rate plus fringe benefits. An employer can satisfy the fringe component by providing bona fide benefits — health insurance, pension contributions, and similar plans — or by paying the cash equivalent on the paycheck, or any combination that adds up.
Classification Discipline
Workers must be paid the rate for the classification of work actually performed, not the cheapest classification a contractor can argue for. A worker classified as a laborer who spends the day doing carpenter's work is owed the carpenter rate for those hours. The legitimate exception is a registered apprenticeship program: apprentices may be paid below the journeyman rate according to the program's approved ratios — a detail the exam uses to test whether you know the exception is narrow.
Certified Payroll and Enforcement
Every contractor and subcontractor on a covered project must submit weekly certified payroll reports through the state's electronic system. Each report lists every worker, their classification, hours worked, wage rate, fringe contributions, and deductions, and is accompanied by a signed statement of compliance. These are sworn documents: a false certification is not a bookkeeping error, it is grounds for enforcement.
When underpayment is found, the core remedy is restitution — the worker is made whole for the difference between what was paid and the prevailing rate — plus potential civil penalties and interest. Contractors with serious or repeated violations risk being barred from public work. The Prevailing Wage Unit investigates complaints, audits payrolls, and publishes decisions, so treat certified payroll as a compliance system, not paperwork.
Where the Rates Come From
The Commissioner builds rates from an annual prevailing wage survey of contractors and from collective bargaining data, then issues determinations project by project. If a needed classification is missing from a determination, the contractor files a supplemental rate request rather than inventing a rate. Determinations can be challenged and are periodically adjusted, so contractors must verify they are working from the current determination for their project. Note also that some local jurisdictions layer on their own rules — Montgomery County, for example, ties its county prevailing wage law to the state's monetary threshold — so the funding source, not just the dollar amount, dictates which regime applies.
Davis-Bacon on Federal Work
Federally funded construction runs on a parallel statute. The Davis-Bacon Act applies to federal contracts in excess of $2,000 for the construction, alteration, or repair of public buildings and public works. The U.S. Department of Labor's Wage and Hour Division issues prevailing wage determinations by county and classification, and contractors file weekly certified payrolls — Form WH-347 is the standard document. Watch for mixed-funding projects: when a project carries both state and federal money, both laws can apply, and the worker is entitled to the higher applicable rate for the classification. Federal-aid highway and housing work is the classic example.
Why a Home Improvement Contractor Should Care
Private residential home improvement — the core MHIC business — is almost never subject to prevailing wage, because it is neither publicly funded nor, usually, above the threshold. The topic is still tested for three reasons:
- The MHIC exam covers Maryland business and labor law broadly, and its writers know contractors cross between residential and public work.
- MHIC contractors do bid publicly funded residential projects — public housing renovations, school-related construction, and weatherization programs funded with state or federal money.
- The exam tests whether you understand the trigger: public funding plus contract value, not whether the work "feels" like a government job.
Common Traps
- The threshold measures the total construction contract value, not the size of your subcontract.
- Prevailing wage is not minimum wage. Minimum wage is a floor for nearly all employment; prevailing wage is a project-specific, classification-specific rate that is typically far higher.
- Paying the basic hourly rate while ignoring the fringe component still underpays the worker.
- Working foremen and owners who personally perform labor on the project must appear on the certified payroll like anyone else.
Under the Maryland Department of Labor's published guidance, which project is subject to the state prevailing wage law?
On a covered public works project, a contractor classifies a worker as a laborer, but the worker spends most days performing carpentry. What must the contractor pay?
The federal Davis-Bacon Act's prevailing wage and weekly certified payroll requirements apply to federal contracts for construction, alteration, or repair of public buildings or public works in excess of:
