Unincorporated Areas
For properties located in unincorporated areas of Madison County, specific regulations apply. Commercial site developments in these areas are regulated by Madison County Public Works. An approved Commercial Site Plan is required before a building permit can be issued for most commercial site developments. This plan must address aspects such as setbacks, parking, utilities, and drainage systems to ensure the project does not negatively impact neighboring properties or the environment. Public Works will verify details related to stormwater runoff, property boundaries, and vehicle access. If a commercial site plan does not comply with Madison County's regulations, the project cannot proceed. Redevelopment of commercial properties in unincorporated areas also requires adherence to site development permit rules, including obtaining a stormwater permit through the county's planning office. A detailed site plan is necessary, outlining new parking layouts, landscaping, building footprints, and drainage features. Madison County zoning ordinances govern these unincorporated areas, with separate permitting procedures and development standards compared to incorporated cities like Huntsville or Madison City.

Overview of HVAC Building Codes in Alabama
Alabama does not have a single, mandatory statewide building code for all residential construction. Instead, the state operates under a decentralized system where building regulation is primarily handled at the local level. Cities and counties have the authority to choose whether to adopt and enforce specific building codes. Consequently, code requirements and the specific editions of codes enforced can vary significantly across different jurisdictions within the state.
Adopted Codes and Standards
While local adoption varies, many jurisdictions in Alabama utilize the International Codes (I-Codes) published by the International Code Council (ICC) as their baseline. For state-regulated buildings (such as state-funded projects), the Alabama Division of Construction Management (DCM) has adopted the 2021 editions of the International Building Code (IBC), International Mechanical Code (IMC), and other related standards. Additionally, the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR) mandates that all certified contractors adhere to specific minimum standards for installation, service, and repair, which include the International Mechanical Code, International Residential Code (IRC), International Fuel Gas Code, and the National Electrical Code (NFPA 70), among others.
Primary State Agencies and Boards
- Alabama Building Commission (ABC) / Division of Construction Management (DCM): Responsible for adopting and amending building codes for state-funded buildings and providing guidance for local jurisdictions.
- Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR): Governs the licensing of HVAC contractors and establishes the minimum technical standards for HVAC installations, service, and repair across the state.
- Alabama Energy and Residential Codes Board: Provides guidance and adopts statewide minimum standards for energy efficiency and residential construction, though enforcement remains a local responsibility.
