Permit Requirements for Mc Grann, Pennsylvania
For HVAC projects in Mc Grann, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Armstrong County.
Authority Having Jurisdiction (AHJ)
Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:
General HVAC Guidelines
Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Armstrong County Building & Safety Jurisdiction
Armstrong County does not have a single, county-wide building department that manages permits for all areas. Instead, the administration and enforcement of the Pennsylvania Uniform Construction Code (UCC) are handled at the local municipal level. Many municipalities in Armstrong County have opted to participate in the "Armstrong County UCC Group," which contracts with a third-party agency, currently Bureau Veritas, to provide building code official and inspection services. Other municipalities may manage their own code enforcement or use different third-party agencies.
Rules for Properties in Unincorporated Areas
Properties located in unincorporated areas (townships) are subject to the specific building code ordinances adopted by that township. Because there is no county-wide authority, you must contact the secretary or building permit officer of the specific township where the property is located to determine if an HVAC permit is required. Even if a township does not have comprehensive zoning, it may still enforce the Pennsylvania UCC, which generally requires permits for mechanical work that involves new equipment, changes in capacity, or alterations to gas or electrical connections. Always verify with your local municipal office before beginning any HVAC work to confirm if a permit is necessary and to obtain the correct application forms.

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.
