HVAC Permit Requirements in Prince George's County, Maryland
In Prince George's County, Maryland, obtaining an HVAC permit is a crucial step for ensuring compliance with building codes and safety standards. The Department of Permitting, Inspections, and Enforcement (DPIE) is the primary agency responsible for issuing these permits. Licensed Master HVACR contractors are typically required to apply for these permits on behalf of property owners.
County-Level Jurisdiction
Prince George's County, through its Department of Permitting, Inspections, and Enforcement (DPIE), has jurisdiction over HVAC permit requirements. Mechanical permits, including those for HVAC systems, are generally applied for online through the county's Momentum permit system. For certain types of permits or those associated with existing permits in the legacy ePermits system, the ePermits online portal may still be used. Master HVACR contractors must register with the county and provide their Maryland State-issued HVACR license number to apply for permits online.
Rules for Properties in Unincorporated Areas
The permit requirements for HVAC installations in Prince George's County generally apply to all properties within the county, including those in unincorporated areas. The DPIE oversees the permitting and inspection process for mechanical systems throughout the county. While specific regulations for unincorporated areas are not detailed separately, the standard county-wide procedures for obtaining mechanical permits and undergoing inspections are applicable.
Key Requirements and Processes:
- Licensed Professionals: Only licensed Master HVACR contractors can apply for mechanical permits.

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.
