Building permits in Huntsville — Alabama's largest and fastest-growing city — are issued by the Building Inspection Department. The City enforces the 2021 IRC and IBC with local amendments.
This guide covers what requires a permit, the City's ePlans Review portal, fees, trade permits, and inspections — so your Huntsville project stays on track.
Huntsville — the Rocket City — is booming, and its permit office is busier than ever. Many projects need approvals from multiple departments (Planning, Zoning, Engineering, Inspection, Natural Resources). Commercial plans must be sealed by an Alabama-licensed design professional in specific cases (e.g., over 2,500 sq ft or certain occupancies). If your site is in a FEMA Special Flood Hazard Area, a Flood Development Permit (FDP) is required before approval.
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.
What requires a building permit in Huntsville?
Under locally adopted codes, a permit is required for most construction activities:
Permit required
- New residential and commercial construction, additions, conversions
- Structural and load-bearing alterations
- Reroofing, windows, siding, and exterior modifications
- Electrical service changes and most wiring work
- HVAC installations, changeouts, and ductwork
- Plumbing alterations, repipes, water heaters
- Decks, porches, fences, patios, pools, garages

Typically exempt
- Painting, wallpapering, tiling, carpeting, cabinet installation
- Countertop replacement and similar finish work
- Minor repairs replacing existing materials in kind
- Small one-story detached accessory structures below the local size threshold (verify locally)
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without a permit in Huntsville can result in fines, stop-work orders, and mandatory removal of unpermitted work.

Huntsville 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).
