HVAC Permit Requirements in Westmoreland County, Pennsylvania
In Westmoreland County, Pennsylvania, HVAC permit requirements are handled at the local municipal level, not by a county-wide building and safety division. This means that the specific rules and application processes will vary depending on the township or borough where your property is located. There is no general county-level permit office for ordinary building permits, including those for HVAC installations.
For properties in unincorporated areas, the same principle applies: you must identify the specific municipality that governs the area and follow their permit procedures. If a municipality has opted out of local Uniform Construction Code (UCC) enforcement, you will need to contact the Pennsylvania Department of Labor and Industry for state-level permit processing.
To obtain an HVAC permit, you will generally need to:
- Identify the specific municipality where your property is located.
- Contact that municipality to inquire about their specific building permit requirements, application process, and any associated fees.
- If the municipality does not handle UCC enforcement directly, you may need to contact the Pennsylvania Department of Labor and Industry.
While the county government, through its Department of Planning and Development, handles matters like subdivision, land development, and zoning, these do not typically encompass individual building permits for HVAC systems.

Pennsylvania HVAC Building Codes and Legislation
Building construction and HVAC systems in Pennsylvania are regulated under the Pennsylvania Uniform Construction Code (UCC), which was established by the Pennsylvania Construction Code Act (Act 45 of 1999). The UCC mandates a statewide building code, though over 90% of municipalities have elected to administer and enforce these codes locally, either through their own employees or certified third-party agencies.
As of January 1, 2026, Pennsylvania has adopted the 2021 International Codes (I-Codes) as the base for the UCC. These codes, which include the International Mechanical Code (IMC), International Residential Code (IRC), and International Energy Conservation Code (IECC), set the standards for HVAC system design, installation, efficiency, and safety. It is important to note that while the state adopts these standards, the UCC Review and Advisory Council (RAC) may recommend specific amendments to these codes for Pennsylvania, and local municipalities may have additional ordinances.
Primary State Agencies and Boards
- Pennsylvania Department of Labor and Industry (L&I): This department is responsible for promulgating regulations to implement the UCC. L&I holds jurisdiction for all state-owned buildings, elevators, and commercial code enforcement in municipalities that have chosen to "opt-out" of local administration.
- UCC Review and Advisory Council (RAC): This 19-member council is tasked with advising the Department of Labor and Industry and the General Assembly on proposed changes to the UCC, including recommendations on whether the latest triennial International Codes should be adopted as published or with state-specific modifications.
