Permit Requirements for Afton, Iowa
For HVAC projects in Afton, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Union County.

Union County HVAC Permit Requirements
Union County, Iowa, does not appear to have its own distinct building and safety division for HVAC permits. Instead, HVAC contractors and work are regulated at the state level by the Iowa Plumbing & Mechanical Systems Board (PMSB).
For properties in unincorporated areas of Union County, the Board of Supervisors has oversight regarding permits for businesses established in these areas. However, specific details regarding HVAC permit requirements for unincorporated areas are not explicitly detailed in the provided search results. It is generally understood that state-level regulations would apply, and local county approval might be necessary for certain aspects, especially concerning utility permits or zoning in unincorporated areas.
In Iowa, HVAC contractors must be licensed by the Iowa Plumbing & Mechanical Systems Board (PMSB). This includes obtaining an apprentice license, a journeyperson license, and ultimately a master license, each with specific experience and examination requirements. Contractors must also register with the Iowa Division of Labor, maintain a permanent place of business, and provide proof of insurance (including $500,000 in liability insurance), a surety bond, and workers' compensation insurance.
Most residential and commercial HVAC projects require permits, especially those involving modifications or additions that affect major building systems, occupant safety, equipment capacity, gas or electrical connections, or the building envelope. This includes installing new furnaces, air conditioners, heat pumps, or altering ductwork.
Union County does offer an online portal for permit applications, which includes categories for Electric, HVAC, Gas, and Plumbing Permits.

State Statutes and Adopted Codes
The State of Iowa adopts model building codes to establish minimum safety and performance standards for construction, including HVAC systems. These adoptions are codified through the Iowa Administrative Code. As of recent updates, the state has adopted the following primary model codes:
- International Building Code (IBC): 2024 edition.
- International Residential Code (IRC): 2024 edition.
- International Existing Building Code (IEBC): 2024 edition.
- International Energy Conservation Code (IECC): 2012 edition.
- State Mechanical Code: Generally based on the International Mechanical Code (IMC).
It is important to note that Iowa Code Chapter 103A allows local jurisdictions (cities and counties) to adopt and enforce their own building codes, provided they are not less restrictive than the state-level standards. Consequently, contractors and designers must verify specific requirements with the local Authority Having Jurisdiction (AHJ) in addition to state-level mandates.
Primary State Agencies and Boards
The administration and oversight of building and mechanical codes in Iowa are managed by several key state entities:
- Iowa Department of Inspections, Appeals, and Licensing (DIAL): This department houses the State Building Code Bureau, which is responsible for the administration of the State Building Code, including plan reviews for state-funded projects and facilities under state jurisdiction.
- State Building Code Advisory Council: Created by Iowa Code section 103A.14, this seven-member body appointed by the Governor provides guidance and oversight regarding the state building code and its updates.
- Iowa Department of Health and Human Services (HHS): This department, often in conjunction with specific boards like the Plumbing and Mechanical Systems Review Board, oversees licensing and standards related to mechanical and plumbing systems.
- State Fire Marshal Division: Part of the Iowa Department of Public Safety, this division is involved in the enforcement of fire safety codes, which often intersect with mechanical and HVAC system requirements.
