Maryland HVAC Building Codes and Legislation
Maryland’s building code framework is primarily governed by the Maryland Building Performance Standards (MBPS), which mandate that all local jurisdictions across the state adopt and enforce the same edition of specific international model codes. As of the most recent state-level updates, Maryland has adopted the 2021 editions of the International Building Code (IBC), the International Residential Code (IRC), the International Energy Conservation Code (IECC), and the International Mechanical Code (IMC). These codes establish the minimum requirements for the design, installation, and energy efficiency of HVAC systems in new construction and major renovations.
Regulatory Agencies and Oversight
The administration of these building codes is overseen by the Maryland Department of Labor, specifically through the Division of Labor and Industry’s Building Codes Administration. This office is responsible for the adoption of state building codes and providing technical assistance to local jurisdictions. Additionally, the licensing and professional regulation of HVACR contractors—including the enforcement of standards for the installation, maintenance, and repair of HVAC systems—is managed by the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration (HVACR) Contractors, which operates under the Department of Labor’s Division of Occupational and Professional Licensing.
