Building permits for unincorporated Madison County — home to Huntsville and the heart of Alabama's aerospace economy — are issued by the Building Inspection Department. Huntsville, Madison, and other cities permit separately.
This guide covers what requires a permit, the County's online permitting system, fees, trade permits, and inspections — so your Madison County project stays on track.
Madison County issues building permits only for properties in unincorporated areas. The department enforces the IRC, IBC, and related trade codes, plus contractor-licensing requirements set by the Alabama Home Builders Licensure Board and the Licensing Board for General Contractors. Note: in Madison County, Huntsville Utilities performs electrical inspections in many areas. Verify jurisdiction before applying.
Alabama has no single statewide building code for private construction. The State Building Code (2021 IBC, amended March 2025 with portions of the 2024 I-Codes) is enforced by the Division of Construction Management (DCM) only for state-owned buildings, public and private schools, hotels/motels, and movie theaters. For everything else, building permits are issued and enforced locally by city and county building departments. Under Act 2024-443, a statewide Alabama Residential Building Code (based on the IRC and IECC) becomes mandatory January 1, 2027, administered by the Alabama Home Builders Licensure Board — so residential code enforcement is moving toward a consistent statewide baseline.

Madison County trade permits
Electrical, plumbing, and mechanical work each needs its own permit and appropriately licensed tradespeople.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by a contractor licensed by the Alabama Electrical Contractors Board (AECB).
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and sewer/gas connections — performed by a contractor licensed by the Alabama Plumbers & Gas Fitters Examining Board.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting — performed by a contractor licensed by the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR Board).
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify contractor licensing. Alabama splits contractor oversight across five state boards: the Alabama Licensing Board for General Contractors (LBGC) licenses commercial/public work (projects $50,000+, swimming pools $5,000+); the Alabama Home Builders Licensure Board (HBLB) licenses residential builders for work over $10,000 and also licenses roofers; the Alabama Electrical Contractors Board, the Plumbers & Gas Fitters Examining Board, and the Board of Heating, Air Conditioning & Refrigeration Contractors (HACR) license those trades regardless of project value. Unlicensed residential homebuilding is a Class A misdemeanor. Verify licenses at gencon.alabama.gov (commercial) and hblb.alabama.gov (residential).
