Maryland's Prevailing Wage Framework: Thresholds, Overtime, and Apprenticeship Contributions
Maryland's Prevailing Wage Law is the operational framework behind the pre-bid contractor registration we covered in the MD Pre-Bid Registration essay. Administered by the Maryland Department of Labor's Prevailing Wage Unit (Division of Labor and Industry), the law applies to public works at $250,000+ with specific funding triggers. A couple of Maryland-specific wrinkles worth knowing: overtime is paid for hours over 10 per day (not just 40 per week), there's a mandatory $0.25/hour apprenticeship contribution on projects over $100,000, and three counties — Montgomery, Baltimore County, Anne Arundel — run their own county-level prevailing wage laws on top.
State thresholds — when the law applies
Maryland Prevailing Wage Law triggers at $250,000 project value or greater, with funding-source tests:
- State agency or state instrumentality projects — any State funding triggers coverage.
- Political subdivision (county/municipal) projects — law applies if 25% or more of funding is State money.
- School construction — $250K+ with 25%+ State funding.
- Mechanical service contracts — law applies at $2,500 or greater (lower threshold for this project type).
Primary source: labor.maryland.gov (Prevailing Wage Unit). See our companion essay on the distinctive MD Pre-Bid Contractor Registration requirement for the registration gate that sits alongside these thresholds.
County-level prevailing wage overlays
Three Maryland counties run their own prevailing wage laws that apply to county-funded construction independent of the state thresholds:
- Montgomery County — $250,000 threshold for county-financed construction.
- Baltimore County — $300,000 threshold for county capital projects.
- Anne Arundel County — County capital contracts over $250,000, or capital contracts with County contribution over $5,000,000.
These county-level laws can extend prevailing wage coverage to projects that wouldn't trigger state prevailing wage (e.g., a county-only-funded project that doesn't meet the 25%-State-funding test for state coverage but does meet the local county threshold).
The wage determination process
Rates are determined by the Prevailing Wage Unit through a structured process:
- Annual survey conducted September-October gathering data on wages paid throughout the state.
- Rate calculation uses collective bargaining agreements, actual wages paid on similar projects, and other wage information. Public hearings can provide input.
- Commissioner determines prevailing wage as:
- The rate paid to 50%+ of workers in a classification in the locality; or
- If fewer than 50% at the same rate, the rate paid to at least 40%; or
- If fewer than 40% at the same rate, a weighted average.
- Issued for each locality — MD's 23 counties + Baltimore City.
- Effective one year.
- Building and Highway rates issued separately, per county and per craft.
- Posting — prime contractors post the Wage Determination prominently at the jobsite.
- Classification gap resolution — if a wage determination lacks a needed classification, contractors contact the Prevailing Wage Unit before starting work.
The 10-hour daily overtime rule
Maryland's overtime rule on prevailing wage projects is more aggressive than federal or most states' framework:
- Daily overtime — hours exceeding 10 in a single day.
- Weekly overtime — hours exceeding 40 in a workweek.
- Sunday and legal holiday work — also overtime eligible.
- Calculation — typically 1.5× the prevailing hourly rate.
The 10-hour daily threshold is important for scheduling decisions. Contractors used to federal 40-hour-weekly overtime only need to plan differently in MD — a 12-hour shift on a Monday triggers overtime for hours 11-12 even if the weekly total stays under 40.
Apprenticeship contributions
MD imposes a mandatory apprenticeship contribution on projects valued at $100,000 or more:
- $0.25 per hour per employee in a covered craft.
- Destination options:
- Registered apprenticeship program.
- Organization with registered apprenticeship programs.
- State Apprenticeship Training Fund.
- Apprentice wages — apprentices must be registered with the Maryland Apprenticeship and Training Program to be paid at apprentice rates.
This is a real line-item cost on MD prevailing wage projects. Not every state imposes this.
Certified payroll — Prevailing Wage Portal
- Electronic submission through the MD Prevailing Wage Portal.
- Timing — certified payroll statements submitted within 14 days after the end of each payroll period.
- Content — verify wage rates paid (straight time + overtime) meet or exceed prevailing wage for the classification, plus accurate classification of worker by work performed.
- Contractor records — business name/address/contact, structure, officers, FEIN, MD tax registration, workers' comp insurance proof.
- Form — federal WH-347 or equivalent. Some counties (e.g., Montgomery) use specific web-based systems like LCPTracker.
- Prime contractor responsibility — certifies and submits all subcontractors' payroll records, attesting to compliance with prevailing wage rates, accurate classifications, and full law compliance.
The MD Department of Labor recommends using a browser other than Chrome for online submission due to known compatibility issues. Noted.
Penalties
- Late payroll submission — $10 per calendar day late.
- Underpayment — $20 per day per underpaid worker.
- Willful violations — debarment, criminal referral where facts support.
Combined with the pre-bid registration requirement (see our MD Pre-Bid essay), MD's prevailing wage framework is among the more rigorous compliance environments in the region.
How MD PW compares to neighbors
- Delaware. Per-project rate request, no pre-bid registration analog. See our DE Per-Project Rate essay.
- Pennsylvania. $25K/$100K thresholds, four rate categories, weekly certified payroll. See our PA PW essay.
- New Jersey. Digital Wage Hub, cross-state DBA interaction common. See our NJ Wage Hub essay.
- Virginia. $250K state agency threshold with locality opt-in. See our VA PW scope essay.
- Maryland. $250K threshold with funding-source rules, 10-hour daily overtime, mandatory apprenticeship contribution, pre-bid registration requirement, three-county local overlays.

What contractors should know
- Confirm threshold and funding source. State funding % matters for political subdivision projects.
- County-level overlays in Montgomery, Baltimore County, Anne Arundel. Check the local ordinance.
- Schedule around the 10-hour daily overtime rule. 12-hour shifts accumulate cost.
- Budget the $0.25/hour apprenticeship contribution on projects ≥$100K.
- Classification matters. Workers classified by actual duties; missing classifications resolved via Prevailing Wage Unit before start.
- Pre-bid registration is the gate. See our MD Pre-Bid Registration essay.
- Portal submission within 14 days of payroll period end.
What to do with this
If you're bidding MD public works: register pre-bid, confirm threshold and state-funding test, verify county overlay if applicable.
If scheduling crews: plan for 10-hour daily overtime, not just 40-hour weekly.
If budgeting: apprenticeship contribution, prevailing wage rates including fringe, certified payroll compliance infrastructure.
If operating in Montgomery, Baltimore County, or Anne Arundel: check county ordinance for lower thresholds.
