Permit Requirements for New London, Pennsylvania
For HVAC projects in New London, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Chester 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:

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.

HVAC Permit Requirements in Chester County, Pennsylvania
There is no county-wide building or safety division in Chester County, Pennsylvania, that issues HVAC permits. Chester County is comprised of 73 individual municipalities, and each municipality is responsible for enforcing building codes and issuing permits within its own jurisdiction. Because there is no centralized county authority for these permits, you must contact the specific municipality where the property is located to determine their unique requirements, fee schedules, and application processes.
Rules for Properties in Unincorporated Areas
In Pennsylvania, all land is located within an incorporated municipality (such as a township, borough, or city). There is no such thing as "unincorporated" land in the sense of being outside of municipal jurisdiction. If you are located in a township, you are still subject to that township's specific building and zoning ordinances. If a municipality does not have its own building department to enforce the Pennsylvania Uniform Construction Code (UCC), they typically designate a third-party inspection agency or utilize the Pennsylvania Department of Labor and Industry to handle permit applications and inspections. You must identify your specific township or borough and contact their building or code enforcement office to confirm the necessary permits for your HVAC project.

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.
