Connecticut Labor Law and Legislation for Mechanical Contractors
Keeping up with Connecticut labor law is part of running a mechanical contracting business. MCAC tracks the legislation, regulatory changes, and compliance requirements that affect our members so you have what you need to stay ahead of it.
When Connecticut legislation affects mechanical contractors, MCAC members hear about it before it becomes a problem on a job — not after the fact.
- PREVAILING WAGE
Prevailing Wage in Connecticut
Prevailing wage law applies to most public works projects in Connecticut, including new construction and renovation projects that meet the dollar thresholds set by the state. For mechanical contractors working on plumbing, pipefitting, and HVAC systems, knowing the current rates and requirements is not optional.
Two significant changes took effect in 2025. Public Act 25-168 updated prevailing wage thresholds and Public Act 25-174 covered off-site fabrication.
July 2025 Rate Adjustment - Annual wage schedule updates are in effect across all trades. Contact the office for current figures.
Members can contact the office for the current prevailing wage rate schedules or find them through Connecticut's Department of Labor.

- CONN-OSHA
CONN-OSHA Requirements
Connecticut has its own OSHA-approved state plan, and mechanical contractors working on public works projects are subject to specific training requirements under CONN-OSHA. Workers on covered projects must have completed an approved construction safety course.
MCAC offers OSHA 10 and OSHA 30 training through our in-house certified trainer to help members meet this requirement.
OSHA 10 & OSHA 30 Training Available
- Paid Sick Leave
Connecticut Paid Sick Leave Law
Public Act 24-8 expanded Connecticut's paid sick leave requirements beginning January 1, 2025. The law now applies to employers with one or more employees, covering most mechanical contractors in the state. Employees accrue one hour of paid sick leave for every 30 hours worked, up to 40 hours per year.
Contractors should review their current policies against the updated requirements to ensure compliance.
Review your current policies against the updated requirements. If you have questions about compliance, contact MCAC for guidance.

- ADDITIONAL REQUIREMENTS
Other Requirements to Know
Wage Theft Liability
Connecticut law holds general contractors jointly liable for wage violations by subcontractors on a project. Mechanical subcontractors should understand how this affects their exposure on multi-contractor jobs.
Prevailing Wage Debarment
Contractors found in violation of prevailing wage law can be debarred from public works projects in Connecticut. MCAC can connect members with resources to understand their obligations and avoid violations.
Renewable Energy Projects
Prevailing wage requirements apply to certain renewable energy projects overseen by the Connecticut Department of Economic and Community Development. Members working in this sector should confirm project coverage before starting work.
Davis-Bacon Act
Federal projects in Connecticut are subject to Davis-Bacon Act prevailing wage requirements, which are separate from Connecticut state law. Members working on federally funded projects should be aware of which law governs their specific contract.
- ADVOCACY
MCAC's Role in Legislative Advocacy
